In light of the same, ERW Piping solutions forwarded currently are subjected to non-destructive tests that include ultrasonic testing as well as pressure-testing. The principles of Resistance Welding.
Consequently, the principle involved in resistance welding is that when an electric current is passed through the junction, a high temperature is obtained by the resistance of the metal to the passage of the current. In addition, the contact surfaces are not in perfect contact and offer the highest resistance and are thus heated up first.
The utility of ERP piping solutions could be seen in various engineering purposes, including fencing, scaffolding, lines pipes.
These piping solutions are economic and works fine in low-pressure applications due to the surface advantages, we recommend the ERW pipeline solution. And the other vital advantage.
In another timeline, in context to attributes, Electric Resistance Welded steel pipes, ERW steel pipes or high frequency welded pipe for short, it has a number of advantages:
Offers high production efficiency at low cost and the price is comparative low for UOE steel pipes.
The physical attributes include astuteness in size and high precision, better than roundness, spiral welded pipe, can save a lot of man-hours on-site counterparts
It Has smooth surface, beautiful appearance, favor within external coating applicator.
Apart from that, ERP piping solutions finds immense importance as:
Water pipes. It could be used for agricultural and irrigation purposes.
Gas pipelines (for natural gas)
Tubes made of steel.
The most important of these factors are:
Strip width
Strip preparation through the mill forming and fin pass stands
Induction of current in the strip, the concentration of the current, and resulting heating of the steel along the strip edges
Presentation of the strip edges at the tube mill weld stand
