An ERW pipe machine (Electric Resistance Welded pipe machine) is a highly efficient industrial system used to manufacture steel pipes by forming flat steel strips into round tubes and welding them using high-frequency electrical resistance. These pipes are widely used in construction, oil and gas transportation, structural engineering, and mechanical applications.
Shijiazhuang Faith Machinery Co., Ltd. specializes in designing and manufacturing advanced ERW pipe production lines, providing reliable, high-speed, and precision-controlled solutions for global steel pipe manufacturers.
An ERW pipe machine is a complete production line that converts steel coils into welded steel pipes through a continuous automated process.
The main steps include:
Uncoiling & leveling – Preparing steel strip
Forming – Shaping strip into a round tube
High-frequency welding – Seam welding using electrical resistance
Cooling – Stabilizing welded structure
Sizing & straightening – Ensuring dimensional accuracy
Cutting – Producing finished pipe lengths
This continuous process ensures high efficiency and consistent product quality.
ERW technology uses electrical resistance heat generated at the steel edges. When pressure is applied, the edges fuse together to form a strong weld without additional filler material.
