Sch 120 Stainless Steel Wall Thickness Seamless Pressure Vessel Pipe 304

As an important equipment in chemical, petroleum, pharmaceutical, and other industries, the safety and reliability of pressure vessels are very important to the stability of the production process and personnel safety. Stainless steel tube material is one of the main materials of pressure vessels, and its use requirements are very strict.

First, the common material of stainless steel pressure vessel pipe

In the design and manufacture of pressure vessels, the commonly used stainless steel materials are 304, 304L, 321, 316, 316L, and so on. Among them, 304 and 316 are widely used materials with stable performance, corrosion resistance, and long service life.

Second, stainless steel pressure vessel tube material selection guide

1. Select materials according to the use environment

When choosing stainless steel materials, we first need to consider its use environment and working conditions. Stainless steel materials with good stability at high temperatures and high pressure should be selected in high-temperature and high-pressure environments, such as 321, 347, etc. In some highly corrosive media, stainless steel materials with good corrosion resistance should be selected, such as 316L, 904L, etc.

2. Select materials according to the requirements

Stainless steel materials also need to be selected according to the use requirements. For example, in some equipment that needs to strengthen heating, it is necessary to choose stainless steel pipe materials with reliable high-temperature resistance, pressure resistance, and corrosion resistance, such as 321, 316L, etc.

Third, stainless steel pressure vessel pipe processing and quality inspection

1. Production of stainless steel pipes

Stainless steel pipes are made through many processes, such as cold drawing, cold rolling, cold tying, cold drawing hot rolling, forging, etc. And in this process, processing quality is the key to ensuring the quality of finished products. For example, the total allowable range of size deviation, surface quality, etc.

2. Quality inspection of stainless steel pipe

The quality inspection of stainless steel pipe is also very important. The manufacturer should carry out quality inspection in strict accordance with the national standards, such as inspection size, mechanical properties, etc., and issue the corresponding inspection report.

In short, in the design and manufacture of pressure vessels, it is particularly important to choose the right stainless steel tube material. In the process of use, it is also necessary to pay attention to the processing and quality inspection of pipeline materials to ensure the safe connection and stable operation of pressure vessels.
