304 stainless steel square pipes are divided into two categories: seamless steel pipes and welded steel pipes (seamed pipes). According to the cross-sectional shape, it can be divided into square tube and rectangular tube. The most widely used are circular steel pipes, but there are also some special-shaped steel pipes such as semicircles, hexagons, equilateral triangles, and octagons.
The tensile strength of 304 stainless steel pipes is twice that of steel pipes and 8 to 10 times that of plastic pipes. The strength of the material determines whether the water pipe is strong, impact-resistant, safe and reliable. Safety and reliability are the primary requirements for building water supply. When subjected to external impact, stainless steel pipes are extremely unlikely to leak. The working pressure of high-rise water supply systems is generally greater than 0.6Mpa. The pressure requirements for pipelines are relatively high. Due to its excellent mechanical properties, thin-walled stainless steel pipes can withstand water supply pressures up to 10Mpa and are especially suitable for high-rise water supply.
Stainless steel square tube 304 has good chemical stability and is not prone to corrosion or chemical reactions in many chemical media. This makes it suitable for use in many areas, including the chemical industry, medical devices, food processing, etc., where materials need to come into contact with a variety of chemicals without damage.
