Diameter: 1/2" to 24" (DN15 to DN600)
Wall Thickness: 0.5mm to 25mm
Length: 6m to 12m (custom lengths available)
Carbon Steel: ASTM A53 Gr. A/B, API 5L Gr.
B/X42/X52/X60
Low-Temperature Steel: ASTM A333 Gr. 1/Gr. 6

(for piling)
Coil Preparation: Uncoiling and leveling of steel
strips.
Forming: Roll-forming into a cylindrical shape.
Welding: High-frequency induction welding (HFW)
or contact welding.
Sizing & Straightening: Precise calibration
for roundness and straightness.
Testing & Inspection: Hydrostatic, ultrasonic
(UT), eddy current (ET), or X-ray testing.
High Strength: Uniform weld seam with mechanical
properties close to the base metal.
Excellent Dimensional Accuracy: Tight tolerances
for OD, WT, and straightness.
Good Weldability: Suitable for further
fabrication (bending, flanging, etc.).
Cost-Effective: More economical than seamless
pipes for medium-pressure applications.
Surface Finish: Smooth, burr-free, and suitable
for coating/galvanizing.
Oil & Gas: Water injection lines, gathering
pipelines, casing pipes.
Construction: Structural columns, scaffolding,
fencing, and piling.
Water & Utilities: Water supply, drainage,
fire sprinkler systems.
Mechanical & Automotive: Roll cages, conveyor
systems, exhaust components.
Low-Pressure Systems: HVAC, compressed air, and
hydraulic lines.

LSAW (Longitudinal Submerged Arc Welded) pipes are high-strength, large-diameter steel pipes widely used in critical infrastructure projects. They are manufactured through three primary forming methods:
UOE Process: Cold-formed using U-ing, O-ing, and Expansion for superior dimensional accuracy.
RBE Process: Roll-Bending and Expansion for cost-effective production.
JCOE Process: J-shape, C-shape, O-ing, and Expansion for customized wall thickness and diameters.
These pipes are ideal for high-pressure transmission and structural applications due to their excellent weld integrity and mechanical properties.
