In the eyes of the public, the thicker the sanitary stainless steel pipe, the better the quality. In fact, it is not the case. How to choose the thickness of the pipe should be considered during the design. So what is the basis for calculating the thickness?
For example, the installation of sanitary stainless steel pipes for water is mainly based on the use environment of sanitary stainless steel pipes. If it is indoors, you can choose 304 stainless steel. If it is outdoors, try to choose 316L sanitary stainless steel pipes. 316 contains molybdenum and is more corrosion-resistant. The thickness here depends on the water pressure. Generally, 1.5 or 2mm is selected. Too thin is easy to crack, and too thick increases the construction cost.
Through the above analysis, when choosing sanitary stainless steel pipes, you must consider comprehensively and choose according to the actual situation. It is recommended that the thickness should be controlled above 1.5 mm outdoors, but the quality of the product must be reliable. Find a regular manufacturer, and the sanitary stainless steel pipes purchased should be tested for their materials before they can be used with confidence.
According to GBT 19228.2-2011 standard, stainless steel water pipes with a nominal diameter of less than 100 and a wall thickness of less than 2 mm are collectively referred to as thin-walled.
Common wall thickness specifications include 0.25 MPa, 0.6 MPa, 1.0 MPa, 1.6 MPa, 2.5 MPa, 4.0 MPa, 6.3 MPa, 10.0 MPa, etc.
Application scope of GNEE ASTM A270 sanitary stainless steel pipe:
Sanitary stainless steel pipes are widely used in petroleum, chemical, aerospace, aviation, nuclear power plants, boiler heat exchangers, pharmaceuticals and other fields.
The outer diameter range is 8-168 mm and the wall thickness is 0.8-8 mm.
Sanitary stainless steel pipes must follow strict dimensional requirements, such as a diameter of 20 mm (allowable deviation ± 0.07 mm) and a wall thickness of 1 mm (allowable deviation ± 0.05 mm).
During the manufacturing process, attention is paid to the surface quality and process control of the product to ensure that each water pipe meets high standards of quality requirements.
