1.Product brief introduction

Stainless steel rectangular pipe is a kind of hollow long steel, widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength is the same, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for the production of various conventional weapons, barrels, shells, etc.

The steel pipe is divided into two categories: seamless steel pipe and welded steel pipe (welded pipe). According to the section shape can be divided into round pipe and shaped pipe, widely used is round steel pipe, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other shaped steel pipe.

For the steel pipe under fluid pressure to carry out hydraulic tests to test its pressure resistance and quality, under the specified pressure does not leak, wet or expansion qualified, some steel pipe also according to the standard or the requirements of the demander flange test, flaring test, flattening test.

Seamless stainless steel pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid tube blank perforated into a tube, and then made of hot rolled, cold rolled or cold drawn. The specifications of the seamless steel pipe are expressed by the outer diameter * the wall thickness of millimeters.

3. Manufacturing process

Most of the square tube processing is the square tube through pressure processing, so that the steel (billet, ingot, etc.) to be processed to produce plastic deformation. According to the processing temperature of the square pipe, the square pipe is divided into two kinds of cold processing and hot processing. The main processing methods of square pipe are:

Rolling: The square tube metal billet through a pair of rotating roller gap (various shapes), due to the compression of the roll to reduce the material section, length increase the pressure processing method, this is the production of square tube commonly used production method, mainly used to produce square tube profiles, plates, pipes. Cold rolling, hot rolling.

Forged square tube A pressure processing method that uses the reciprocating impact force of the forging hammer or the pressure of the press to change the blank into the shape and size we want. Generally divided into free forging and die forging, commonly used for the production of large profiles, billets and other cross section square pipe inch larger materials.

Pulling square tube: It is the processing method that has been rolled metal billet (type, tube, product, etc.) through the die hole to reduce the section and increase the length. Most of it is used for cold processing.

Extrusion: is a processing method in which the square tube places the metal in a closed extrusion tube and exerts pressure at one end to extrude the metal from the specified die hole and obtain the finished product of the same shape and size, which is mostly used in the production of non-ferrous metal square tubes.

Square rectangle is a very widely used closed section steel, compared with the same cross-sectional area of the round pipe, it has high strength, large bending section modulus, easy assembly and stable, beautiful and other advantages, widely used in vehicles, subway, shipbuilding and other industries. Especially in the construction industry, large-size square and rectangular pipes have become the main load-bearing structural components in steel structure buildings. As a typical closed section steel, square rectangular pipe will leave residual stress in each process of manufacturing. The different processing technology of square pipe will inevitably produce different degree of residual stress.

4.Product specification range

Stainless steel square pipe: 8*8-280*280(mm) Thickness: 0.3-6.0(mm)

Stainless steel rectangular tube: 20*10-100*200(mm) Thickness: 0.4-6.0(mm)

Applications:

Widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength is the same, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for the production of various conventional weapons, barrels, shells, etc.

Specifications:

Competitive Advantage:

1.Excellent corrosion resistance: stainless steel square pipe in a variety of strong acids, alkali, salt and other corrosive media is stable, will not be corroded and discoloration.

2.Good processing performance: stainless steel square pipe is easy to cut, bend, welding and cold forming, suitable for a variety of complex processing technology.

3.High strength, high toughness: stainless steel square pipe has much higher strength than ordinary steel, can withstand greater load, and has better toughness and plasticity.

4.Good high and low temperature performance: stainless steel square pipe at high temperature oxidation resistance, high temperature resistance are very good, while the strength and toughness at low temperatures also maintain good.
