manufacturing process
---Coil receipt and inspection---Coil slitting--Recoiling after slitting---Coil Uncoiling and joining
---Coil Leveling--Forming---High frequency welding---Trimming flash---Heat treatment---Air Cooling
---Sizing--- Cutting to length---Inspection and testing sampling --- Hydrostatic testing
---Final Auto UT on welding seam---Manual UT at pipe ends
---Laboratory test – Chemical analysis--- Mechanical Test-- Final dimension inspection
Material & Corrosion Protection
Constructed from non-alloy or low-alloy carbon steel conforming to ASTM standards, these pipes provide a balance of strength and cost-effectiveness. Various external and internal coating options are available for enhanced durability, including:
External Coatings: 2-layer Polyethylene (2PE), 3-layer Polyethylene (3PE), Fusion-Bonded Epoxy (FBE), galvanization, or mill varnish.
Internal Coatings: FBE, cement lining, or bitumen coating to protect against internal corrosion and optimize flow efficiency.
Applications
Oil & Gas Transmission: The primary application is for onshore and offshore pipelines transporting crude oil, natural gas, and refined products.
High-Pressure Fluid Transport: Used in hydraulic systems, high-pressure water supply, and industrial fluid conveyance networks.
Structural Applications: Suitable for construction frameworks, piling, and other structural components requiring high strength and durability.
Utilities: Employed in water distribution and other municipal infrastructure projects
