GB/T 13296 Seamless Stainless Steel Tubes For Boiler And Heat Exchanger

Introduction

GB/T 13296 is belong to Chinese standard, it is equivalent to ASTM A213 standard. In terms of material, GB/T 13296 standard specifies that steel pipes should be made of stainless steel materials, which have good corrosion resistance and high temperature performance, and can maintain stable performance in harsh environments. At the same time, the standard also specifies the chemical composition of the material, including the maximum content of elements such as carbon, silicon, manganese, phosphorus, and sulfur, as well as the minimum content of elements such as chromium and nickel, ensuring the mechanical properties and corrosion resistance of seamless pipes.

In terms of manufacturing process, GB/T 13296 standard puts forward strict requirements for the manufacturing process of steel pipes. Steel pipes should be manufactured by hot rolled or cold drawn process to ensure uniform wall thickness, smooth inner and outer surfaces. At the same time, heat treatment, straightening, cutting and other processes should be carried out during the manufacturing process to meet the requirements of mechanical properties and dimensional accuracy.
