ERW (Electric Resistance Welded) Plumbing and Tubes are manufactured from bits of hot-steel. The steel is flattened and put in furnace letting you manoeuvre throughout the welding electrodes.
Further, the electrodes that are aluminium disc type are attached to the Vertical revolving noodle assembly that helps to contact on all sides of the seam and temperatures are increased into the welding point.
The exterior flash has been removed whilst the tube leaves the electrodes along with the within flash is damaged by an air hammer after the tubing was cooled. This creation is called Electric Resistance Welded or ‘ERW Pipe’ (Which is also known as ‘ท่อ erw‘ in the Thai language).
Shapes and sizes:
It’s offered in various sizes and contours to accommodate customer requirements. Broadly speaking, ERW Steel Tube is offered in the scope between 2 3/8 inch to 24-inch outer diameter in an assortment of lengths as much as 100 feet. ERW pipe is significantly cheaper and more durable than simple steel pipes. It’s most appropriate to flat pipes.
Before attaining the market, ERW steel pipes and tubes are all processed through several evaluations involving ultrasonic weld inspection, hydro-test, bevel test, micro-meter test, ring gouge and straightness test to make sure its own quality.
ERW steel tubes can be employed in various heavy industrial uses such as – fencing, scaffolding, line plumbing, technology purposes, petroleum business, industrial structure and agricultural sector and the home market.
