Heat treatment after tube box welding

2022-02-24View Original

Thread Content

Does it mean that if the diameter of the lateral opening in the tube box exceeds 1/3 of the inner diameter of the cylinder, heat treatment after welding is required regardless of whether the opening is in the tube box cylinder or the head?

You can refer to the GB/T151 standard; it’s also related to the material, I guess!
