Stainless steel square pipe is a square shaped tubular steel pipe, also known as square and rectangular steel pipe. It is the abbreviation of equilateral angle steel prism with equal thickness as the condition. Hot rolled or cold rolled (rolled) seamless steel pipe can also be used.Generally, the specification of stainless steel pipe only depends on its inner diameter and wall thickness, and its length can be determined according to the needs of consumers. The common specifications of stainless steel pipe in the market are: the inner diameter is more than 6.0mm, and the wall thickness is less than 13mm; The inner diameter is greater than 30mm and the wall thickness is greater than 1.2mm; The inner diameter is greater than 30mm, and the wall thickness is less than 1.2mm.

Stainless steel rectangular pipe is a kind of hollow long steel, which is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc. in addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures.

Stainless steel pipe is a kind of economical section steel and an important product in the iron and steel industry. It can be widely used in life decoration and industry. Many people in the market are used to make stair handrails, window guards, railings, furniture, etc. There are two common materials, 201 and 304.Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin-walled pipes and the successful development of new reliable, simple and convenient connection methods make them have more irreplaceable advantages than other pipes. They will be used more and more in engineering, and will be more and more popular. The prospect is promising.
