410S Stainless Steel Square Pipe

Introduction

Stainless steel square tube is a kind of hollow long steel, because the section is square, it is called square tube. A large number of pipes are used 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 lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Classification

Stainless steel square pipe classification: square pipe is divided into two categories: seamless steel pipe and welded steel pipe (seamed pipe). According to the cross-sectional shape, it can be divided into square and rectangular pipes. The widely used round steel pipes are round steel pipes, but there are also some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel pipes.

For stainless steel square pipes under fluid pressure, hydraulic tests should be carried out to check their pressure resistance and quality. If there is no leakage, wetting or expansion under the specified pressure, it is qualified. Some steel pipes should be rolled according to standards or requirements of the buyer. Edge test, flaring test, flattening test, etc.

Square tube specification: 5*5~150*150 mm Thickness: 0.4~6.0 mm

Square tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S.

Production Process

Round bar preparation → heating → hot rolling and piercing → cutting head → pickling → grinding → lubrication → cold rolling → degreasing → solution heat treatment → straightening → pipe cutting → pickling → finished product inspection.

performance analysis

Metals can react with oxygen in the atmosphere to form an oxide film on the surface. The iron oxide formed on ordinary carbon steel will continue to oxidize, so that the rust will continue to expand, and eventually holes will be formed. This protects the carbon steel surface by electroplating with paint or oxidation-resistant metal, but this protective layer is only a thin film, and if the protective layer is destroyed, the underlying steel begins to rust again. Whether the stainless steel pipe is corroded is related to the chromium content in the steel. When the chromium content in the steel reaches 12%, in the atmosphere, a layer of passivation and dense chromium-rich oxide is formed on the surface of the stainless steel pipe to protect the surface, which can prevent further re-oxidation. This oxide layer is extremely thin, through which the natural luster of the steel surface can be seen, giving stainless steel a unique surface. If the chromium film is destroyed, the chromium in the steel and the oxygen in the atmosphere will regenerate a passive film, which will continue to play a protective role. In some special environments, stainless steel will also fail due to some local corrosion, but different from carbon steel, stainless steel will not fail due to uniform corrosion, so the corrosion allowance is meaningless for stainless steel pipes.
