Our plastic-coated pipes are manufactured using a high-temperature fusion bonding process, ensuring strong coating adhesion. They undergo rigorous multi-stage testing—including pinhole detection, bending and flattening tests, and temperature resistance evaluations—to ensure full compliance with quality standards. During transit, we utilize specialized packaging—sealing both ends of the pipes and applying external protective wrapping—to prevent damage from bumps or impacts. Should any non-human-induced quality issues arise upon delivery, our company assumes full responsibility for their resolution.
