You can also use spectral analysis and other means of on-site inspection of the material, you can also observe the appearance, hardness test, and other preliminary judgment, but these methods are relatively inexact.How to express the size of the stainless steel elbow, DN, and inches between how to convert?Size is usually expressed in nominal diameter (DN), such as DN15, DN20, etc., there will also be an outside diameter × wall thickness of the expression of DN and inch conversion relationship: 1 inch ≈ 25.4mm, for example, DN15 corresponds to 1/2 inch, DN20 corresponds to 3/4 inch.How to determine the pressure level of a stainless steel elbow?Mainly based on the design pressure of the piping system, operating temperature, medium characteristics, and other factors to determine. At the same time, we should refer to the relevant standards, such as the PN series (PN2.5, PN6, etc.) or Class series (Class150, Class300, etc.), to select the elbow to meet the system pressure requirements.What is the difference in the structure of stainless steel elbows with different pressure ratings?Generally speaking, the higher the pressure rating, the thicker the wall thickness of the elbow, and the higher the strength requirements of the material. Elbows with high-pressure ratings may require more stringent manufacturing processes and quality control to ensure safety and reliability under high pressure.Does surface finish have an effect on the service life of stainless steel elbows?There is a great impact. Good surface treatment can effectively prevent elbow surface rust, and corrosion, and reduce wear and tear, thereby extending its service life. For example, elbows with passivation treatment are less likely to rust and have a longer service life than untreated ones in the same environment.
