Quick Detail:                               
Size Range: O.D.:6-350mm     W.T.:1-35mm      L:max12000mm  

Steel Grade: E195, E237, E275, E355,

 

Description:

ERW+ DOM

The tubes are manufactured from electric welded pre-tubes by cold drawing or other suitable processes. 

The tubes not include welds used for joining lengths of flat rolled strips prior to forming the pre-tube

 

Description:

Mechanical tubing made from hot or cold-rolled steel.

Covers electric-resistance-welded low carbon steel tubing for use as mechanical tubing

 

Advantage:

Good concentricity, Better price than seamless.
