LSAW Welded Pipe DN1080 API 5L X65 With Internal Epoxy Coating For Water Injection

Engineered for the rigorous demands of oilfield water injection infrastructure, Huayang's DN1080 API 5L X65 pipes feature a high-performance micro-alloyed steel body optimized for high-pressure service. The 1080mm LSAW sections are manufactured using the advanced JCOE cold-forming process, which ensures superior dimensional roundness and a high-quality longitudinal weld. To combat the highly corrosive nature of injection water, the internal surface is treated with a high-build epoxy coating, providing a smooth, hydraulically efficient barrier that prevents pitting and tuberculation. The X65 PSL2 specification ensures a high strength-to-weight ratio and guaranteed fracture toughness, essential for withstanding the cyclic stresses of injection pumps. As a premier industrial manufacturer, Huayang subjects each DN1080 unit to 100% non-destructive evaluation (NDE) and rigorous coating adhesion tests, delivering a durable, high-integrity conduit that maximizes operational lifespan in complex energy production environments.
