May 12 2015· This month we take a hard look at the differences between ERW DOM and Seamless Tube. ERW (Electric Resistance Welded) The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round square and rectangular steel tubing.
Apr 12 2022Rolled and welded tubes can be up to 16 feet in diameter and more than inches thick. Several advantages of ERW tube No fusion metal is used in the manufacturing process. This means the pipes are very strong and durable. Welds cannot be seen or felt.
The total installed capacity of GEI219 ERW tube mills is approximately 1500KW. Including Solid state HF 600KW Forming machine main motor 160KW 2 set 220KW 1 set Flying saw blade sawing motor 90KW and saw drive motor 55KW.

Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However because the manufacturing process is fast it is ideal for large production runs of small (<= 24 in.) diameter sections.
Specification of Steel Pipe. Fusion Weld pipe begins as coiled steel of the required The edges of the skelp are then firmly pressed together by rolls ERW pipe is cold formed however require minimum tonnage to set up on a specific size lengths up to 115 feet in either ID or OD dimensions up to Some mills are using the more modern bar.

In the classic sense a tube mill is a kind of welded roll form system however not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been finetuned to run a specific diameter range typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.
