Electric Resistance Welding (ERW) carbon steel pipe mills are key equipment in the continuous production of welded steel pipes for a wide range of industrial applications, including construction, water transmission, structural frameworks, and machinery manufacturing. At Shijiazhuang Faith Machinery Co.,Ltd, the ERW carbon steel pipe mill is designed to combine efficient production with high dimensional accuracy.
The ERW pipe mill starts with uncoiling steel strip from a coil, leveling it to remove residual stress, and guiding it through forming rollers. The strip edges are heated using high-frequency electrical current and then pressed together using a set of squeeze rollers to form a weld without any filler material. This welding process offers high speed and cost-effective performance, particularly suitable for producing thin-to-medium wall thickness pipes in large volumes.
Uncoiler: Handles coils up to 20 tons with hydraulic expansion for secure clamping.
Strip Accumulator: Ensures continuous strip feeding to avoid interruptions during coil changes.
Forming and Sizing Mill: Uses multiple sets of rollers to gradually form the round shape and size the pipe after welding.
High-Frequency Welder: Provides concentrated heating of strip edges to achieve a consistent and reliable bond.
Flying Saw Cutting System: Cuts pipes to length without stopping line movement, using servo-controlled tracking and clamping systems.
Pipes produced by ERW carbon steel pipe mills are widely used in:
Mechanical tubing
Scaffolding pipes
Oil and gas transportation
Fire protection systems
Greenhouse and agricultural irrigation systems
Faith Machinery offers customization options in pipe diameter (Φ10mm – Φ355mm), wall thickness (0.5mm – 12mm), and line speed (up to 120m/min), adapting each mill to specific customer requirements.
