Structural Steel Pipe

Structural Steel Pipe. A wide range of applications rely on structural steel pipe for strength and stability. Gnee steel supply welded and seamless pipe for structural applications to customers in all industries. As a leading steel pipe supplier, Gnee steel offers a large inventory of pipe and tubing sizes from 1/8” NPS to 48” NPS.

Spiral welded pipe

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the pipe seam. It can produce large-diameter steel pipes with narrow strip steel. It is mainly used for oil and natural gas pipelines.

T3094 Special-shaped seamless steel pipe

Special-shaped seamless steel pipe is a general term for seamless steel pipes with other cross-sectional shapes except round pipes. According to the different cross-sectional shapes and sizes of steel pipes, they can be divided into equal wall thickness special-shaped seamless steel pipes (codenamed D), unequal wall thickness special-shaped seamless steel pipes (codenamed BD), and variable diameter special-shaped seamless steel pipes (codenamed BJ). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts.
