304/304L/TP304 Stainless Steel Square Pipe

Stainless Steel Square Pipe

The stainless steel square tube is a hollow strip of steel, which is called a square tube because the section is square.

a large number of pipes used to transport fluids, such as oil, natural gas, water, gas, steam, etc.

In addition, when the bending and torsional strength are the same, the weight is lighter.

Therefore, it is also widely used in the manufacture of mechanical parts and engineering structures.

Specification

5*5~150*150 mm

Thickness

0.4~6.0 mm

Material

304、304L、TP304、TP316L、316、316L、316Ti、321、347H、310S.

（What we are talking about in this article is the 300 series stainless steel square tube）

Classification

Stainless steel square tube classification:

Square tube is divided into seamless steel pipe and welded steel pipe (with seam pipe).

According to the shape of the section, it can be divided into square and rectangular tubes.

Widely used are round steel pipes, but there are also some special-shaped steel pipes such as semicircular, hexagonal, equilateral triangle, and octagonal.

For stainless steel square tubes subjected to fluid pressure, hydraulic tests are required to verify the pressure resistance and quality.

No leakage, wetting or expansion is allowed under the specified pressure. Some steel pipes are also subjected to the crimping test, the flaring test, the flattening test, etc. according to the standard or the requirements of the purchaser.

Production Process

Round steel preparation → heating → hot rolling perforation → cutting head → pickling → grinding → lubrication → cold rolling processing → degreasing → solution heat treatment → straightening → pipe cutting → pickling → finished product inspection.
