Product Description

stainless steel pipe

Stainless steel pipes are hollow cylindrical metal products made from chromium nickel alloy, widely recognized for outstanding corrosion resistance, high strength, heat stability and hygienic performance. They are manufactured in two main types: seamless pipes and welded pipes, covering common grades like 304, 316L, 321 and 904L.

Featuring a self-repairing passive oxide film, they effectively resist rust, acid, alkali and chloride corrosion, ensuring long service life in harsh environments. With smooth inner walls, low fluid resistance and easy cleaning, they meet strict hygiene standards.

These pipes are extensively applied in fluid transportation, petrochemical, food & beverage, pharmaceutical, water supply, construction, marine engineering and mechanical structures. They combine durability, recyclability and aesthetic appeal, making them an essential industrial material for reliable and eco-friendly piping solutions.

Seamless stainless steel pipe

Stainless steel welded pipe 

Seamless stainless steel pipe, also known as stainless steel seamless tube, is made by piercing steel ingots or solid tube blanks to form a rough tube, which is then hot-rolled, cold-rolled, or cold-drawn. The specifications of seamless steel pipe are expressed in millimeters as outer diameter * wall thickness. According to different production methods, they can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, etc. They are mainly used in building water supply systems, hot water supply, high-pressure pipelines, mechanical structural materials, and hydrogen fuel cell vehicle piping.

Stainless steel welded pipe is a steel pipe made by rolling and welding commonly used steel materials or strips through a unit and mold. Compared with seamless steel pipe, stainless steel welded pipe has advantages such as high precision, uniform wall thickness, high internal and external surface brightness, and the ability to be made to any length, and it is also more affordable. Stainless steel welded pipe has a wide range of applications, including mechanical structures and fluid transportation based on national standards, as well as being widely used in construction decoration, automobile manufacturing, energy engineering and other industries.
