American standard A106B
seamless steel tube is a widely used high-quality steel pipe, which is widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. American standard A106B seamless pipe implements ASTM A106 / A106M high temperature operation carbon steel seamless steel pipe standard, grade B level. It can be seen from the pipeline standard of ASME B31.3 chemical plant and petroleum refinery: American standard A106 seamless pipe material temperature range: -28.9 ~ 565 ℃.
