Product Description:Xinxiang Songjin Machinery Co., Ltd. is dedicated to the field of high-efficiency and energy-saving heat exchange tubes. The integrally formed finned tubes developed by the company are at the world's leading level. The integrally formed spiral finned steel tubes use No. 20 steel pipes compliant with the GB/T3087-2008 standard for seamless steel tubes for low and medium-pressure boilers, or 20G steel pipes compliant with the GB/T5310-2017 standard for seamless steel tubes for high-pressure boilers as the base tubes. These are processed through hot-rolled fin tube machines via rolling and pressing to form spiral finned heat exchange tubes with an integrated structure of fins and base tubes.   Integrally formed spiral finned tubes are primarily used as next-generation heat exchange components in medium and high-pressure boiler economizers and air preheaters. They offer advantages such as "high efficiency, energy savings, cost-effectiveness, resistance to ash accumulation, wear resistance, long service life, and strong environmental adaptability." Compared to conventional bare tubes or high-frequency welded spiral finned tubes, the integrally formed spiral finned tubes produced by our company have the following technical advantages: 1. No welding required, longer service life. Integrally formed spiral finned tubes eliminate the need for welding, completely removing contact thermal resistance between the fins and the base tube and preventing fin loosening. They exhibit high efficiency, stability, and reliable heat transfer performance, with a longer service life, making them particularly suitable for harsh environments, such as economizers in circulating fluidized bed boilers with high flue gas velocity and hard particles. The weld adhesion rate of welded finned tubes is difficult to achieve at 100% and is challenging to inspect. Welding creates contact thermal resistance and requires post-weld thermal stress treatment. Long-term use can lead to weld cracking, causing fins to detach from the tubes and further increasing contact thermal resistance, which reduces heat transfer efficiency and necessitates tube replacement.If a crack gap is 0.1 mm, with air's thermal conductivity at 0.021 kcal/(m2·h·°C), the thermal resistance reaches 0.0045 m2·h·°C/kcal, equivalent to the thermal resistance of a 180 mm thick steel plate. Integrally formed finned tubes do not suffer from the issues associated with welded fins. Their service life matches that of the base tube material and is 3-4 times longer than that of high-frequency welded or brazed spiral finned tubes. Higher heat transfer efficiency. Taking economizers as an example, the total heat transfer coefficient on the flue gas side is generally no more than 100 kcal/(m2·h·°C), while the heat transfer coefficient on the water side inside the tubes is as high as 5000~10000 kcal/(m2·h·°C). Thus, the flue gas side plays a dominant role in the heat transfer process. According to the heat transfer formula Q = kFΔt, increasing the heat transfer area enhances heat transfer. Experimental test reports from the State Key Laboratory of Multiphase Flow at Xi'an Jiaotong University indicate that the heat transfer coefficient of integrally formed spiral finned tubes is 6~7 times that of bare tubes. Thermal performance test reports on finned tube bundles also show that the Nusselt number (Nu) of integrally formed spiral finned tube bundles is about 4 times that of bare tubes, with a significantly higher heat transfer coefficient and improved heat transfer performance. In contrast, research literature on welded spiral finned tubes indicates that their heat transfer coefficient generally does not exceed that of bare tubes by a significant margin, and the Nusselt number (Nu) of their tube bundles is about 4 times that of bare tubes. Additionally, integrally formed finned tubes do not suffer from the inherent contact thermal resistance and weld adhesion issues of welded tubes. The fin roots feature a small R smooth transition, and the fin cross-section has a trapezoidal structure. These characteristics make the heat transfer performance of integrally formed finned tubes significantly superior to that of high-frequency resistance welded and brazed spiral finned tubes. Reduced tendency for ash accumulation, slagging, and clogging. Removing ash, slag, and fouling from heat transfer surfaces is a critical maintenance task for heat exchange equipment such as economizers.Since the thermal conductivity of the ash and slag layer on the flue gas side of economizers is very low, even a thin fouling layer can create significant thermal resistance. Each millimeter of ash and slag layer is equivalent to a 400 mm thick steel wall. The presence of fouling thermal resistance not only reduces heat transfer but also significantly increases the tube wall temperature, leading to overheating and potential tube failure, which can cause accidents. The integrally formed finned tubes feature a small R smooth transition between the fin roots and the base tube, with a smooth surface that eliminates the ash accumulation, slagging, and clogging issues common in welded finned tubes due to folded and uneven fin roots. Even if some ash accumulates, it is easily blown off, ensuring effective heat transfer and improving operational economy. Higher tensile strength, pressure resistance, and wear resistance. Integrally formed finned tubes are produced by extruding and rolling thick-walled tubes, effectively subjecting the tubes to an additional high-temperature rolling process.Safety performance evaluation reports from the China Special Equipment Inspection and Research Center and comprehensive technical inspection reports from the National Steel Product Quality Inspection Center indicate that the integrally formed spiral finned tubes produced by our company exhibit higher longitudinal tensile strength, yield strength, and hardness compared to the base tubes, i.e., the national standard boiler steel tubes 20 and 20G, though with a reduction in elongation. The increased hardness enhances the wear resistance of the integrally formed finned tubes, particularly the improved hardness of the fins, which is beneficial for resisting erosion by flue gas dust. This addresses the severe wear issue in fluidized bed boilers caused by high flue gas velocity and hard particles. The reduction in elongation, i.e., decreased plasticity, does not affect the use of the finned tubes, as manufacturing economizers with these tubes does not require tube bending (only end welding), and high plasticity is not a critical requirement. In summary, integrally formed finned tubes represent a new manufacturing method for spiral finned tubes and can be considered, within certain applications, as the next-generation product replacing high-frequency welded and brazed spiral finned tubes. The integrally formed finned tubes produced by our company have undergone comprehensive technical testing and evaluation by multiple national relevant agencies, meeting or exceeding the relevant standards for steel tubes used in the boiler industry. In terms of the quality assurance system, the company strictly adheres to the established "Integrally Formed Spiral Finned Steel Tube Production Process Operating Procedures," which cover specifications for processing machinery and equipment, operational procedures, raw material procurement, and product inspection. more>

Product Description:Benefits of Using Triple-Start Threaded Tubes in Heat Exchange Equipment:(1) Simultaneous enhancement of heat transfer inside and outside the tube;(2) Fast processing speed, excellent results, and low cost;(3) Wide applicability: enhances heat transfer for evaporation, condensation, gaseous flow heat transfer, and liquid flow heat transfer both inside and outside the tube;(4) Self-adjusting capability with thermal expansion and contraction;(5) Reduced scale formation.I. Product Introduction:Since Luwsun et al. from the United States published the first academic report on threaded tubes in 1966, threaded tubes have garnered significant attention as high-efficiency heat exchange components. They are now increasingly widely used in China. Threaded tubes are heat-conducting tubes with internal convex and external concave spiral shapes, manufactured by cold-rolling ordinary smooth tubes. They are suitable for use as heat exchange tubes in equipment such as boilers, condensers, low-pressure heaters, oil coolers, and air coolers.II. Advantages:1. Application in boilers: After optimization for heat exchange and flow resistance, the heat transfer capacity of one threaded tube is equivalent to 1.7–1.8 ordinary steel tubes of the same size. This not only significantly reduces the number of steel tubes required but also allows for a smaller boiler shell diameter. As a result, steel consumption for pressure components is markedly reduced, saving materials and lowering costs.2. Application in the air conditioning and refrigeration industry: Compared to ordinary smooth tubes, threaded tubes offer 1.5–2.0 times the heat transfer surface area, greatly improving refrigerant flow patterns and enhancing boiling and condensation heat transfer inside the tubes. The refrigerant is propelled in a spiral motion by the internal threads, reducing pressure loss by over 50%. Manufacturing processes such as tube expansion and welding are the same as for ordinary tubes. This enables the miniaturization and lightweighting of air conditioners, saving approximately one-third of the tube weight compared to smooth tubes. Operation is energy-efficient, reducing costs.3. Application in heat exchange equipment: Steel or stainless steel tubes are formed in one pass through machine rolling. Scale on the surface of threaded tubes forms in a spiral pattern. Temperature changes during equipment operation cause the tubes to expand and contract, enabling the scale to self-detach. In contrast, scale on smooth tubes forms a cylindrical layer with no self-detaching capability. Threaded tubes are now widely used in power plant condensers and boiler auxiliary heat exchange systems, making them an ideal replacement for smooth tubes and copper tubes.Forming Process:After cold-rolling steel tubes, the tube dimensions shrink by 0.1% to 0.5%. Factors affecting the shrinkage length include: 1. Thread depth (e); 2. Pitch (s); 3. Thread radius (r). These parameters can be adjusted as needed.Processing diameter: ∮6mm–89mm; processing thickness: 0.5mm–5mm; adjustable spiral direction, adjustable pitch, adjustable thread depth. more>

Product Description:Xinxiang Songjin Machinery Co., Ltd. holds a national invention for the spiral flat tube forming machine. The tube forming process ensures that the wall thickness remains unchanged and does not exceed the material's yield point, maintaining the mechanical integrity of the tube. Both ends of the tube remain circular, facilitating connection with the tube sheet. The range of tube materials is extensive, including carbon steel, stainless steel, Cr-Mo alloys, duplex and super duplex alloys, as well as titanium, zirconium, and tantalum, with tube diameters ranging from φ12 to φ40.The heat transfer rate of spiral flat tubes is significantly better than that of ordinary smooth tubes, with lower pressure drop and reduced susceptibility to fouling and blockage.A simulation study was conducted with fluids having a Reynolds number less than 1000 to compare the differences between spiral flat tubes and spiral elliptical flat tubes, while analyzing the field synergy angle of the two tube cross-sections and comparing them with straight flat tubes and straight elliptical flat tubes. The results indicate that the Nusselt number on the wall of both spiral tubes increases with the Reynolds number, with the rate of increase gradually slowing; the comprehensive performance evaluation factor of both spiral tubes increases with the Reynolds number, and that of the spiral flat tube is higher than that of the spiral elliptical flat tube, making it the preferred choice under these conditions. For self-supporting spiral tubes, at the same Reynolds number, the pressure loss of the spiral elliptical flat tube is lower than that of the spiral flat tube, but its heat transfer performance is inferior to that of the spiral flat tube.The spiral flat tube (Twisted tube) was proposed by Sweden's Alards company and improved by the American Koch Heat Transfer Company, LP, as an enhanced heat transfer tube.The structural feature of the spiral flat tube is that any cross-section of the heat exchange section is elliptical. When assembled into a heat exchanger, it can be a mixed tube bundle (i.e., a combination of spiral flat tubes and smooth tubes) or a pure spiral flat tube bundle.Its manufacturing process involves two forming steps: "flattening" and "twisting." The tube cross-section resembles an ellipse, with the aspect ratio of the ellipse designed based on the flow velocities of the tube side and shell side. When the tube side flow rate is low, the aspect ratio can be increased to reduce the flow area and increase the velocity. The unique structure of the spiral flat tube allows both the tube side and shell side fluids to undergo spiral motion simultaneously, enhancing turbulence. The overall heat transfer coefficient of a spiral flat tube heat exchanger is 40% higher than that of a conventional heat exchanger, while the pressure drop remains almost the same.In recent years, spiral flat tube heat exchangers have been further refined and developed. They are more reliable and efficient than other types of heat exchangers and can be used in almost any system where shell-and-tube heat exchangers are specified. Since 1984, thousands of spiral flat tube heat exchangers have been manufactured and sold worldwide, applicable to gas-gas, liquid-liquid, and liquid-gas heat exchange processes across various industries, including chemical, petroleum, food, papermaking, power, metallurgy, mining, and urban heating.Spiral flat tubes can simultaneously improve the heat transfer coefficients on both the inner and outer sides of the heat exchange tube, thereby significantly enhancing the overall heat transfer coefficient and total heat exchange efficiency. more>

It is compact, low-noise, has a high load capacity, and can self-lock, making it more convenient and simpler to operate. I believe you have guessed it—yes, this is today's protagonist: the screw jack (also known as the mechanical jack).The screw jack largely benefits from its internal structure: the worm gear mechanism. This structure was originally used in reducers to reduce speed while amplifying torque, meaning a small force can transmit a large torque. Later, it was discovered that using this mechanism in lifting equipment for hoisting or lifting motions was also an excellent choice, leading to the birth of the screw jack.Due to the internal worm gear structure, screw jacks are very compact and aesthetically pleasing, making them suitable for any fixture without appearing突兀. It also gives screw jacks two speed ratios, fast and slow, to adapt to different usage scenarios.The worm gear screw jack (mechanical jack) is an electromechanical motion execution unit that cleverly combines an electric motor, reduction system, and screw transmission. It can be used alone or in multiple combinations, like building blocks, connected via right-angle轉(zhuǎn)向器, couplings, and connecting rods, and can accurately control the lifting, reciprocating, flipping, and other motions of the mechanism according to a certain program. Thus, it can replace traditional hydraulic and pneumatic transmissions in various scenarios. This motion unit, primarily based on the worm gear screw jack, provides engineers in the digital era with broad design space for product development. This series of mechanical jacks features self-locking, a unique square groove housing that enhances heat dissipation, extends the service life of lubricating grease, and more. The use of ductile iron for the housing material significantly improves the strength and performance of the housing, as well as its wide application in high/low temperatures. The square tail cover design prevents the screw from rotating. Advanced processing equipment and assembly techniques ensure high product quality, while advanced design concepts create products with strong impact resistance, high strength, low noise, long service life, and compact size. They are widely used in industries such as solar energy, metallurgy, food, and water conservancy.

Such motion units, primarily based on worm gear screw jacks, provide engineers in today's digital era with broad design possibilities for product development. This series of screw lifts features self-locking capability, a unique square groove housing that enhances heat dissipation, extends the service life of lubricating grease, and more. The use of ductile iron for the housing material significantly improves strength and performance, as well as broad applicability in high/low-temperature environments. The square tail cover design prevents the screw from rotating. Advanced processing equipment and assembly techniques ensure high product quality, while innovative design concepts create products with strong impact resistance, high strength, low noise, long service life, and compact size. They are widely used in industries such as solar energy, metallurgy, food, and water conservancy. The safety nut design monitors product wear, eliminates hidden risks, and can be combined with geared motors and various accessory modules to meet any customer requirements.Product Advantages1. High rigidity, precise positioning, generally self-locking after power-off2. Simple and compact system structure, no need for complex pumps, valves, oil tanks, air sources, or piping systems.3. Low noise, no fluid leakage, minimal environmental pollution.
