Factory Outlets Stainless Steel Round Pipe - Square Stainless Steel Tube/Pipe – Xingrong
Factory Outlets Stainless Steel Round Pipe - Square Stainless Steel Tube/Pipe – Xingrong Detail:
Classification:
Stainless steel square tube classification: square tube is divided into seamless steel pipe and welded steel pipe (seam pipe). According to the shape of the section, it can be divided into square and rectangular tubes. Round steel tubes are widely used, but there are also some semi-circular, hexagonal, equilateral triangle, octagonal and other special-shaped steel tubes.
For stainless steel square pipes that are subjected to fluid pressure, hydraulic tests are required to check their pressure resistance and quality. No leakage, wetting or expansion under the specified pressure is qualified. Some steel pipes are also rolled according to standards or demander requirements Side test, flaring test, flattening test, etc.
Square tube specification: 5*5~150*150 mm thickness: 0.4~6.0 mm
Material of square tube: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S [1]
Production Process:
Round steel preparation → heating → hot rolling 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, causing rust to continue to expand and eventually form holes. This can use paint or oxidation-resistant metal for electroplating to protect the carbon steel surface, but this protective layer is just a thin film, if the protective layer is damaged, the underlying steel will begin 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%, a layer of passivated, dense chromium-rich oxide is formed on the surface of the stainless steel pipe in the atmosphere to protect the surface and prevent it Further reoxidized. This oxide layer is extremely thin, through which you can see the natural luster of the steel surface, giving stainless steel a unique surface. If the chromium film is destroyed, the chromium in the steel and the oxygen in the atmosphere regenerate a passive film and continue to play a protective role. In some special environments, stainless steel will also fail due to some local corrosion, but stainless steel and carbon steel will not fail due to uniform corrosion, so the corrosion margin is meaningless for stainless steel pipes.

Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases. Stainless steel pipe resists oxidation, making it a low-maintenance solution that is suitable for high temperature and chemical applications. Because it is easily cleaned and sanitized, stainless steel pipe is also desired for applications involving food, beverages and pharmaceutical applications.

The term “pipe” and “tube” are often used to describe the same product, but it is important to know the difference. Though they share the same cylindrical shape, steel pipes are measured by the interior diameter (ID), whereas steel tubes are measured by the outside diameter (OD) and wall thickness. Another difference is that pipes are used to transport fluids and gases, while tubes are used to build parts or structural components.
Tube and fittings for:
Fluid application in Sanitary, Beverage, Food, Dairy, Pharmaceutical product production and storage.
Heat applications such as heat exchangers, condenser tube
Mechanical applications such as automotive, structural, and decorative
Pipe and fittings for:
Fluid application in Petrochemical, Desalination, Mineral processing, Power generation, Oil and Gas recovery plants.
Industrial, structural and decorative applications
The above are some of the industry and applications where stainless steel tubular products are generally is use. Overall they have a use in environments where strength, corrosion, hygiene or aesthetics is a factor in design and application.
