Stainless steel special-shaped pipe is the general name of steel pipe with other section shapes except round pipe. Stainless steel shaped pipe is widely used in various structural parts, tools and mechanical parts. Compared with the round tube, stainless steel special-shaped tube generally has a larger moment of inertia and section modulus, as well as a larger bending and torsional resistance, can greatly reduce the weight of the structure, save steel. Stainless steel shaped pipe has the characteristics of high strength, variable surface technology, easy to clean, no deformation, durable, weather resistance and so on. It has a strong corrosion resistance, can effectively resist air, water, steam and other weak corrosive medium.
