Difference between ERW, DOM and Seamless Tube

ERW pipe is made by moving metal and afterward welding it longitudinally across its length.  ERW pipe meaning has a welded joint in its cross-segment, while consistent line has no joints all through its length since it is made by expelling the metal to the ideal length.

What Technologies are used to manufacture Seamless & ERW Pipes?

For the development of consistent lines and cylinders up to 7-inches OD, CPE Innovation is the incredibly famous innovation.  The "Fitting Factory" innovation is utilized for bigger widths.

ERW (Electric Resistance Welded)

ERW is a welding cycle that includes both spot and crease welding. Crease welding is ordinarily utilized during the assembling of round, square and rectangular steel tubing. The edges are constrained together under tension as a butt joint and afterward welded by warming the material to temperatures above 2000° F.

(DOM) Drawn Over Mandrel

In fact, DOM full form isn't a kind of steel tube, yet rather the cycle in which the cylinder is done.  It is viewed as a great cylinder, and is typically developed from SAE 1020 or 1026 steel. DOM seamless tubing is frequently erroneously referred to as "consistent cylinder".

Expulsion is used to make the consistent cylinder.  This cycle transforms a strong round steel bar into a round tube by passing it through the middle.
