316L Stainless Steel Welded Pipe
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.
316L stainless steel welded pipe contains added molybdenum and is a low-carbon material, exhibiting extremely strong resistance to chloride ions, salt spray, and acid and alkali corrosion, making it suitable for humid coastal and chemically corrosive environments. It has excellent high-temperature resistance, is not prone to rusting or deterioration during welding, and is a clean and safe material. It boasts stable mechanical properties, is durable under pressure, and has a long service life, making it widely applicable in seawater transportation, food processing equipment, medical devices, and various heavy-duty corrosion-resistant projects.
