The commonly used standards for thick-walled seamless steel pipes primarily cover aspects such as manufacturing, quality control, and usage requirements. These standards are designed to ensure the quality and performance of the pipes, meeting the needs of various fields. Below, we will detail several commonly used thick-walled seamless steel pipe execution standards.

Firstly, it is the GB/T8163-2018 Standard for Seamless Steel Tubes for Fluid Conveyance. This standard applies to general seamless steel tubes used for conveying fluids such as water, oil, and gases. It specifies the dimensions, shape, weight, technical requirements, and testing methods for the steel tubes. The manufacturing process must meet certain chemical composition requirements, such as limits on the content of carbon, silicon, manganese, sulfur, and phosphorus, to ensure the mechanical properties and corrosion resistance of the tubes. Additionally, the tubes must undergo heat treatment and hydrostatic testing to ensure their quality and reliability.
