Standards & Grades

1. ASTM A53 Standard

Ideal for low-to-medium pressure applications and structural purposes.

‌Grades Available:‌ Grade A, Grade B, Grade C.

‌Key Features:‌ Excellent weldability and formability. Grade B is the most commonly used grade for general mechanical and plumbing applications.

‌Typical Applications:‌ Water and gas distribution, fire protection systems, structural columns, and fencing.

2. API 5L Standard

Specifically engineered for the transportation of oil, natural gas, and other fluids in the petroleum industry.

‌Grades Available:‌ PSL1 & PSL2; Grades B, X42, X46, X52, X60, X65, X70.

‌Key Features:‌ Higher strength-to-weight ratio, strict chemical composition control, and enhanced toughness for harsh environments. PSL2 offers superior performance for sour service and offshore applications.

‌Typical Applications:‌ Long-distance pipelines, offshore drilling, high-pressure gathering lines, and refinery processes.

Surface Treatment & Corrosion Protection

To extend service life and adapt to various environmental conditions, we offer multiple surface finishing options:

‌Black Varnish/Oiled:‌ Standard protection for indoor or short-term storage.

‌Galvanized (Hot-Dip/Electro):‌ Superior corrosion resistance for outdoor and moisture-prone environments.

‌3LPE/3LPP Coating:‌ Three-layer polyethylene/polypropylene coating for long-distance buried pipelines.

‌FBE (Fusion Bonded Epoxy):‌ Ideal for internal corrosion protection in oil and gas lines
