2205 stainless steel welded pipes are available in outer diameters of 10-3000mm, wall thicknesses of 0.5-30mm, and standard lengths of 6m/12m. Welding processes are primarily TIG/MIG, with surface pickling and passivation. Connection methods include welding and flanges. Custom processing is available with short and reliable delivery times.

254 stainless steel welded pipe, commonly known as 254SMO welded pipe, is a type of super austenitic stainless steel welded pipe, corresponding to UNS number S31254 and German grade 1.4547. It belongs to the 6-molybdenum super stainless steel series and is named for its approximately 6% molybdenum content. It is not a duplex steel, but a high-alloy austenitic stainless steel, possessing extremely high resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking.

309S stainless steel welded pipe has a high chromium and nickel content, excellent high-temperature resistance, and can withstand temperatures up to 1000℃ for extended periods. It also exhibits strong resistance to high-temperature oxidation and thermal fatigue. Combining good corrosion resistance and weldability, it is not prone to deformation and cracking in high-temperature environments. Leading Chinese stainless steel welded pipe manufacturers recommend 309S as a suitable choice for medium- and high-temperature industrial pipelines such as high-temperature flues, industrial kilns, and heat treatment equipment.

321 stainless steel welded pipe incorporates titanium, effectively inhibiting intergranular corrosion, making it less prone to rust and cracking after welding, and exhibiting excellent thermal stability. It has good high-temperature resistance, is not easily deformed under alternating hot and cold conditions, has good plasticity for easy processing and forming, and strong fatigue resistance. Chinese stainless steel welded pipe manufacturers recommend 321 material as a suitable choice for boiler piping, thermal equipment, and high-temperature heat exchange pipelines.

The core advantage of 310S stainless steel welded pipe is its high-temperature resistance, capable of continuously withstanding 1150℃ and short-term withstand of 1200℃. Leading Innovation Factory in China typically stocks the following specifications: outer diameter 16-219mm, wall thickness 0.8-5.0mm, standard length 6 meters, and supports custom orders.

Our 316L stainless steel welded pipe factory offers commonly used outer diameters ranging from 16mm to 219mm, standard wall thicknesses from 0.8mm to 3.0mm, and a standard length of 6 meters. As a leading Chinese stainless steel welded pipe manufacturer, we can produce various mainstream round pipe specifications, support thickened pipe wall processing, and also customize non-standard sizes and lengths. Finished products can be polished or brushed, suitable for various engineering applications including chemical, seawater transportation, and medical equipment.
