Hot working specification of 42CrMo alloy steel pipe：
When the heating temperature is 1150~1200 degrees C, the starting temperature is 1130~1180 degrees C, the

At present, hot rolling technology is mostly used in seamless pipe production. Because of the high temperature, the deformation resistance is relatively small.

ASTM A106 seamless steel pipe is carbon steel pipe for boilers, heat exchangers and high-temperature service. ASTM A106 includes 3 steel grades: A106 grade A, A

Thick-walled steel pipes are steel pipes with a ratio of outer diameter to wall thickness of less than 20. It is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe, and high-precision str
