ERW Pipe Electric Resistance Welded

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.

The difference between SureThread CW Pipe & Import ERW

Nov 06, 2015 · Made to ASTM A53 Type F Grade A specifications, SureThreadTM CW pipe is easier to work with than import ERW pipe because of its uniform grain structure. This makes it easier to bend, cut and thread. The difference in quality all begins with how the pipe is manufactured. Where import ERW pipe is cold-formed, SureThread is hot-formed. Tube and pipe basics:How to achieve the perfect bendBending starts with knowing the properties of the tube or pipe youre working with.

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes. Pipe size is specified with two non-dimensional numbers:a nominal pipe size (NPS) for diameter based on inches and a schedule (Sched. or Sch.) for wall thickness.NPS is often incorrectly called National Pipe Size, due to confusion with national pipe thread (NPT).
