Specifications:
Production process of hot rolled tubes :
Hot rolling → heating → piercing → three roller helical rolling,
tandem rolling or extrusion → tube knockout → sizing or tube
diameter reduction → cooling → semi-finished hot rolled seamless
pipe → straightening → water pressure test → labeling →
warehousing.
Classifications :
Hot rolled seamless steel tubes can be classified into the common
steel pipe, low and medium pressure boiler seamless steel tube,
high pressure boiler seamless pipe, stainless steel hot rolled
pipe, and more.
Advantages :
Due to our adoption of hot rolling process, the original casting
structure of the steel slab for making hot rolled pipe is
destroyed. This means that the crystalline grains of steel material
are refined, and the defects of the microstructure of steel slab
are eliminated, which results in improved mechanical performance
and denser microstructure of steel materials along the rolling
direction.
Hence, our hot rolled seamless steel pipe features good mechanical
property and superior intensity.
