SSAW (Spiral Submerged Arc Welded) Pipe is manufactured by hot-rolled steel coil, continuously formed into spiral shape and welded by double-sided submerged arc welding process.

LSAW Pipe

ERW (Electric Resistance Welded) pipe is produced by high-frequency electric resistance welding of hot-rolled steel strips or coils. It has a smooth weld line, precise dimensions, high pressure resistance and good straightness.

Seamless pipe is manufactured by hot rolling, cold drawing or extrusion process without any welded seam. It features high strength, good pressure resistance, uniform wall thickness and excellent mechanical properties, widely used in oil & gas transmission, petrochemical plants, power stations, boiler systems, mechanical structures and high-pressure pipeline projects.

OLET is divided into:Weldolet、Sockolet、Threadolet、Latrolet、Nipolet、Flangolet

Slip-on Flange is a type of pipeline flange with a low hub, allowing pipes to slip into the flange before welding. It is easy to install and align, widely used in low-to-medium pressure systems, general industrial pipelines, water treatment, petroleum refining, and utility projects.

Weld Neck Flange (WN Flange) is a high-pressure pipeline connecting component with a long tapered hub, designed to be butt-welded to pipes. It provides excellent reinforcement, high strength, and strong sealing performance, widely used in oil & gas, petrochemical, refinery, power plant, and long-distance pipeline projects. It effectively reduces stress concentration and improves fatigue resistance under high temperature, high pressure, and harsh working conditions.
