UNIASEN products

For Processing Technic

Uniasen - Electric Resistance Welding (ERW) Pipes

Electric Resistance Welding (ERW) pipes applied wide hot rolling steel prole as raw material, and went through pre-bending, continuous forming, welding, straightening, cutting and other processes. The pipe has short weld joints, high dimensional accuracy, uniform thickness, and excellent surface and can bear high pressure.

Uniasen - Seamless Steel Pipes

Seamless steel pipes are often one of the preferred pipe materials in environments that need to withstand high pressure or high temperatures. Seamless (SMLS) steel pipes have a hollow section. They are used extensively in pipelines for transportation, such as pipes for transporting oil, natural gas, coal gas, water and certain solid materials, boilers, etc.

Uniasen - Spiral Submerged Arc Welded (SSAW) Pipes

Spiral submerged arc welded (SSAW) pipes has spiral welding joints and the pipes are welded and formed at the same time. The strip steel with the same speci?cation can produce SSAW pipes with various diameters.

Uniasen - Longitudinally Submerged Arc Welding (LSAW) Pipes

Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double-sided submerged arc welding. The ?nished products have larger speci?cations and the welding joints have excellent ductility, plasticity and good sealing.

Uniasen - Hollow Structural Section (HSS) Square Pipe

Hollow structural section (HSS) is a type of metal pro?le with a hollow tubular cross section, including Square Pipes and Rectangular Pipes. Hollow Sections are commonly used in welded steel frames where members experience loading in multiple directions.
