Stainless steel thick wall pipes are mainly used in the industrial field, especially for the transport of fluids or gases with high pressure. In contrast, civilian stainless steel water pipes usually use thinner wall thickness, which is enough to meet the transportation needs of domestic water. In general, the selection of conventional wall thickness can be, such as 3 wall thickness of the pipe can meet the requirements of use. For domestic water, a thickness of 25mm is a more appropriate choice, and 3 thicknesses are more adequate. The thickest specification of welded pipe in stock is 6mm, but it can also be customized according to demand, up to 10mm thick. The thickest specification of seamless pipe in stock is 16mm, but whether it can be customized needs to be determined according to the specific situation. Stainless steel pipe of 304 material is recommended, because this material is non-toxic and harmless.


Regarding the size specifications of stainless steel pipes, the common round pipe specifications are Φ3, Φ4, Φ5, Φ6, Φ7, Φ8, Φ9, Φ95, Φ10, Φ127, Φ159, Φ191, Φ222, Φ254, Φ318, Φ381 and Φ4216. From the perspective of user economic requirements, as long as the wall thickness can meet the service life requirements is selected. According to the experience of Germany, Japan and other countries in the use of stainless steel water pipes, the use of thick wall stainless steel pipes specified in industry standards, such as DN15 stainless steel pipes with wall thickness of 0.8mm, can fully meet the service life of water pipes of more than 70 years.


The threaded connection is also called the wire connection, which is a connection method that connects the pipe to the pipe or the pipe to the valve through the internal and external threads. For the transportation of low pressure fluid galvanized steel pipe, the general requirements of the nominal diameter of 150mm below, the working pressure of 16MPa below. Some equipment accessories with threads and parts that often need to be removed are also often connected with threads. Marine stainless steel materials are SUS304, SUS304L, SUS316 and SUS316L. If you need to find stainless steel pipe brands, you can refer to Shuangxing stainless steel pipe, Great Wall stainless steel pipe, Sansande stainless steel pipe, Haili stainless steel pipe and Xiyouwo stainless steel pipe manufacturers. I hope you find this information helpful.


Can be measured by tools to choose the appropriate stainless steel pipe thickness model material brand and other information, there are also some stainless steel pipe manufacturers directly printed the relevant information on the pipe, so that it can be more convenient to buy. The tensile strength of 304 stainless steel pipe is 520MPA. The hydraulic test pressure formula of stainless steel welded pipe for fluid is GBT12772008P=2RSD, where P represents the test pressure (MPa), R represents the stress (take the yield point 50%, MPa), S represents the nominal wall thickness of the steel pipe (mm), and D represents the nominal outer diameter of the steel pipe (mm).
