What is a Seamless Pipe?

Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, machinery and instruments, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture, kitchenware, etc.a

mless pipes are derived from solid steel that is in s

Section shape

Stainless steel pipe can be divided into round pipe and special-shaped pipe according to the cross-sectional shape. Special shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes, hexagonal tubes, octagonal tubes and various cross-section asymmetric tubes. Special shaped pipes are widely used in various structural parts, tools and mechanical parts. Compared with circular pipe, special-shaped pipe generally has larger moment of inertia and section modulus, and has greater bending and torsion resistance, which can greatly reduce the structural weight and save steel.

According to the profile shape, stainless steel pipe can be divided into equal section pipe and variable section pipe. Variable section pipes include conical pipes, stepped pipes and periodic section pipes.

A335 P91, steel model. It has high oxidation resistance and high temperature steam corrosion resistance

characteristic:

It not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness, high and stable durable plasticity and thermal strength. When the service temperature is lower than 620 ℃, the allowable stress is higher than that of austenitic stainless steel. Above 550 ℃, the recommended design allowable stress is about twice that of T9 and 2.25Cr-1Mo steel.

application

It can be used as steel pipe for high-temperature superheater and reheater of subcritical and supercritical boilers with wall temperature ≤ 625 ℃, as well as high-temperature header and steam pipe with wall temperature ≤ 600 ℃, as well as nuclear electric heat exchanger and furnace pipe of petroleum cracking unit.
