Shijiazhuang Faith Machinery's ERW mills transform carbon steel coils into structural and fluid-carrying conduits through electric resistance welding technology.
Material Preparation
Coils undergo decoiling and edge trimming before entering the forming section. Precision straighteners remove residual stresses while accumulators enable continuous operation during coil transitions.
Forming & Welding
Roll forming stations progressively shape the steel strip into tubular form. Contact electrodes apply controlled pressure and electrical current, generating resistance heat along the seam. Squeeze rollers consolidate the molten edges into a homogeneous weld.
Thermal Management
Immediate water quenching stabilizes the weld structure. Subsequent normalizing furnaces restore ductility while air-cooling tunnels achieve final metallurgical properties. Temperature gradients are continuously monitored to prevent distortion.
Industry Applications
These mills produce pipes for construction scaffolding, water transmission, and mechanical systems. The consistent dimensional accuracy ensures compatibility with standard fittings while weld reliability meets pressure containment requirements.
Carefully analyzing steel tube mill for sale options against these criteria helps identify the solution offering the best long-term value and alignment with production goals. Shijiazhuang Faith Machinery Co.,Ltd.provides comprehensive solutions and guidance throughout the selection process, focusing on delivering mills designed for sustainable productivity, quality output, and dependable operation.
