Metallurgical Toughness & Sour Service Readiness
Offshore and marine environments demand line pipe materials with elevated yield strength and low-temperature impact energy. As a certified API 5L Grade X65 PSL2 seamless pipe manufacturer, Haihao Group supplies PSL2 grade pipes featuring controlled carbon equivalents and micro-alloyed chemistry (Nb, V, Ti) to maximize weldability and structural stability.
For the NACE-designated portion of the order, strict controls over chemistry, hardness, and heat treatment ensure exceptional resistance to sulfide stress cracking (SSC) and hydrogen-induced cracking (HIC) when handling corrosive wet gas or crude oil streams.
Surface Protection & Quality Assurance
Prior to ocean transit, every pipe underwent stringent quality inspection and surface preparation at our API 5L Grade X65 PSL2 seamless pipe manufacturer facilities:
Black Varnish Coating: Uniform black anti-corrosion painting was applied across the outer surfaces to protect against ocean salt spray and oxidation during transit and storage.
Hydrostatic & Non-Destructive Testing: 100% hydrostatic testing and full-body ultrasonic or electromagnetic NDT were conducted to confirm pressure boundary integrity and zero internal flaws.
Material Traceability: Full EN 10204 3.1 Mill Test Certificates accompanied the shipment, detailing heat analysis, mechanical yield/tensile testing, Charpy V-notch impact values, and NACE compliance data.
Sourcing from a proven API 5L Grade X65 PSL2 seamless pipe manufacturer provides energy contractors with verified field reliability and code compliance.
