Hot Rolled And Cold Drawn Galvanized Tube Carbon Steel Sealess ASTM A106B B36.10 A53B Pipe
Carbon steel pipes are divided into hot-rolled and cold-rolled (drawn) steel pipes. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless pipe can be up to 6mm and the wall thickness can be up to 0.25mm. The outer diameter of thin-walled pipe can be up to 5mm and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
Outside Diameter (Inch) | Wall thickness (Inch) | Outside Diameter (mm) | Wall thickness (mm) | |
| From 1/2 to 5 | From SCH40 to XXS | From 25 to 356 | From4 to 80 | |
| Length | From 2m to 12.5m in accordance with customers' requirements | |||

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.
