Product Introduction

Large Diameter Thick Wall Seamless Steel Pipe is designed for project supply. Large-diameter thick-wall seamless round steel pipe with no weld seam, high pressure resistance, and strong performance for energy, chemical, machinery, and foundation projects.

 

Key Features

• Hot-rolled seamless forming eliminates weld seams and provides superior pressure and impact resistance.

• Large-diameter thick wall gives high bending and compressive strength with low deformation risk.

• Smooth internal and external walls support beveling, flanging, NDT, and anti-corrosion processing.

• Dense pipe body and high-temperature resistance suit heavy industrial and energy pipeline service.
