Products

Chinese manufacturers supply color-coated aluminum coils directly from the source, offering base materials including 1060 pure aluminum, 3003 rust-proof aluminum, and 5052 high-corrosion-resistant aluminum. PE polyester and PVDF fluorocarbon coatings are available, with rich colors and weather resistance. Standard specifications are readily available, and we support customized leveling, slitting, and forming processes. The process is efficient, and material quality assurance reports are included.

2507 stainless steel welded pipe manufacturers have ample inventory, with outer diameters ranging from 16-219mm, wall thicknesses from 0.8-6mm, and standard lengths of 6 meters. Custom sizes and lengths are available upon request. Polishing and brushing treatments are supported. These pipes are widely used in flue gas desulfurization, seawater engineering, and pipelines for heavily corrosive chemicals.

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.
