New Coated Anti-Corrosion Production Line for Flanged Steel Pipes by Qingdao Huashida Solves Industrial Leakage Pain Points

Company News Popularity: 7 November 10,2026

The new coated anti-corrosion production line for flanged steel pipes developed by Qingdao Huashida Machinery Co., Ltd. integrates five core processes: enclosed environmental-friendly pre-treatment, intelligent induction precision preheating, synchronous electrostatic coating on the inner and outer surfaces of steel pipes as well as flange end faces, and constant-temperature closed-loop curing. It enables one-time clamping and positioning of flanged steel pipes for continuous full-process processing.

Controlled by precise programs, the equipment avoids ineffective coating on the critical sealing areas of flanges, eliminates the risk of flange seal failure from the process perspective, and solves the long-standing common leakage problem in the industry.
