stainless steel square pipe
Product Description

Special Shaped SS Pipe

Stainless Steel is durable, resists corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures. Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for greater corrosion resist

ance from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures. 304 pipe connects with fittings to transport air, water, natural gas, steam, and chemicals to storage tanks and in residential plumbing, and kitchen and food applications. 316 pipe connects with fittings to transport air, water, natural gas, steam and chemicals in chemical manufacturing, industrial and chemical transportation, and food production and processing. Stainless steel is available in pipe lengths over 12" and nipple lengths 12" and shorter.


Shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless steel pipe (code BD), variable diameter special-shaped seamless steel pipe (code BJ). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.


Special Shaped Ss Tube and seamless rectangular pipes are also special-shaped seamless steel pipes. The weight calculation method of seamless square management theory: (side length + side length) × 2 × wall thickness × 0.00785 × length; seamless square management theory weight calculation method :Side length x 4 x wall thickness x 0.00785 x length.
