20G high-pressure boiler tubes are divided into general boiler tubes and high-pressure boiler tubes according to their high-temperature performance. General boiler tubes and high-pressure boiler tubes can be divided into various steel tubes. The hardness of the high-pressure boiler tube is also very strong. Boiler tubes are steel tubes commonly used in industrial test environments. Boiler tubes generally use seamless tubes, and boiler tubes are also seamless tubes.

20G high-pressure boiler tube is a common boiler tube material, which is mainly used in the manufacture of high-pressure boilers. The following is a detailed introduction to 20G high pressure boiler tube:

1. Specifications: The specifications of 20G high-pressure boiler tubes are generally 48-219mm in outer diameter and 3-40mm in wall thickness.

2. Wall thickness: The wall thickness of 20G high-pressure boiler tubes is very important for the safe operation of high-pressure boilers. Generally, the wall thickness is required to be above 4mm.

3. Mechanical properties: The tensile strength of 20G high-pressure boiler tubes is 410-550MPa, the yield strength is 245MPa, and the elongation is greater than 25%.

4. Chemical composition: The chemical composition of 20G high-pressure boiler tubes includes carbon (C) ≤0.17-0.24%, silicon (Si) ≤0.17-0.37%, manganese (Mn) 0.35-0.65%, phosphorus (P) ≤0.035%, Sulfur (S) ≤0.035%.

In conclusion, 20G high-pressure boiler tube is an important boiler tube material with good mechanical properties and high temperature resistance, and is widely used in high-pressure boiler and pipeline transportation fields.
