Product introduction:LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.
Longitudinal Submerged-Arc Welded Steel Pipe Process: LSAW – UO(UOE), RB(RBE), JCO(JCOE,COE) DSAW -Double Submerged arc welded
Usage: used for low pressure liquid delivery, such as water, gas, and oil
Certificate:EN10217,EN10219,API 5L
The UOE LSAW STEEL PIPE mill features the most advanced technology and process, achieves high production efficiency, stable product quality and is equipped with complete inspection equipment. UOE mill adopts U & O forming, the formed pipes are welded inside through five internal welding stations with three wires, and welded outside through four external welding stations with three wires. In accordance with different requirements of the customers, the welded pipe can be expanded either by mechanical or hydrostatic expand to improve dimensional accuracy, and eliminate residual stress.

LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.
LSAW pipe used to convey low pressure liquid or high pressure petroleum or natural gas, and can be also used widely in structural supports or foundation. The advantage for LSAW type is they could produce more thick wall thickness of pipes, maximum to 120mm.
Features:
- Large diameter steel pipes
- Thick walls
- High-Pressure resistance
- Low-temperature resistance
Tests:
- Chemical Component Analysis
- Mechanical Properties – Elongation, Yield Strength, Ultimate Tensile Strength
- Technical Properties – DWT Test, Impact Test, Blow Test, Flattening Test
- X-ray Test
- Exterior Size Inspection
- Hydrostatic Test
- UT Test
