ASTM A106 GR B Seamless Pipe Production Process
The production process of ASTM A106 GR B seamless steel pipe mainly includes the following steps:
Preparation stage: Cut the steel plate into billets of a certain length, and clean and trim them.
Piercing stage: The billet is perforated into a rough tube by a piercing machine to form a preliminary steel tube shape.
Rolling stage: The rough tube is rolled multiple times to form a steel tube of a certain shape and size.
Heat treatment stage: The steel tube is subjected to high-temperature tempering treatment to eliminate stress, improve corrosion resistance and mechanical properties.
Sizing and straightening: The diameter and wall thickness of the steel tube are precisely adjusted, and straightening treatment is performed to ensure the dimensional accuracy and straightness of the steel tube.
Inspection stage: The steel tube is strictly inspected and tested to ensure that its quality meets the standard requirements.
