Hot Rolled Seamless Pipe Tube (HRS) – Definition & Applications

Hot Rolled Seamless Pipe Tube (HRS) is produced by piercing and hot-rolling billets, resulting in pipes with uniform wall thickness, dense structure, and high strength. It is widely used in oil & gas pipelines, boilers, high-pressure equipment, chemical plants, and structural applications, especially for large-diameter and thick-wall pipes.

Hot Rolled Seamless Pipe Tube (HRS) – Features & Advantages

Uniform wall thickness with excellent pressure resistance.

High strength & toughness suitable for high-temperature and high-pressure service.

Wide size range, especially large diameter and heavy wall pipes.

Excellent processability, including cutting, welding, machining, coating.

Compliance with international standards (ASTM, ASME, API, EN, DIN, GB).
