Hot Rolled Seamless Steel Pipe

Hot Rolled Seamless Steel Pipe is produced by heating solid steel billets to high temperature,then piercing,rolling,and expanding under thermal processing state.It features a thick wall,high strength,good toughness,and excellent pressure resistance.With no welded seams,it is widely used in medium and large diameter fluid transportation,structural engineering,petroleum,natural gas,and high-temperature and high-pressure industrial pipelines.

Key Features

Large size&thick wall:Suitable for medium and large diameters and heavy wall thickness,which is hard to achieve by cold processing.

High strength&toughness:Good impact resistance and fatigue resistance under high temperature and pressure.

Good pressure resistance:Uniform structure,no weld defects,stable performance for fluid and gas transmission.

Cost-effective:Higher production efficiency,lower cost compared with cold finished pipes.

Good weldability&machinability:Easy to cut,bend,flange and weld on site.

Main Materials
