ERW pipes are the abbreviated form of the Electrical Resistance Welded Pipes. The demand for these pipes has risen exponentially in the recent years to a huge extent. They are used in a diversified range of application in the railings, gravity flow, conveyors and several other mechanical and piping systems.
Manufacturing Process of the Electrical Resistance Welding Pipes:
These electrically resistant pipes are manufactured from the hot rolled coils or the seam plates. These rolled coils are levelled and processed by the shearing force and the coil ends are then welded by electrical resistance welding method for reducing the losses and maintaining the continuity. The continuity of the production according to the various diameters is gradually and continuously maintained in the welding stands. After the pipes are produced, several type tests are carried out to verify the mechanical, the chemical and the physical properties of the pipes thoroughly. Once the tests are completed successfully, the Electrical Resistance Welding pipes are manufactured.
Classification of the Electrical Resistance Welding Pipes:
These pipes are generally classified into two categories according to the general forms of the pipes: the longitudinal Pipes and the Spiral Pipes. While in accordance to the applications of the pipes, they are widely classified into several categories. And they are
1. Galvanized pipes with zinc coating on the surface
2. Blow oxygen pipes used for blowing oxygen especially for the manufacturing of the pipes of small diameters.
3. Electrical welding pipes generally used for conduit electrical wiring.
4. Welding thin walled tube used for making toys, furniture etc.
Features of Electrical Resistance Welding Pipes:
The ERW pipes are of low grained, high performance, high deformability, high tolerance in their dimensions, high quality, high strength, wide applications, huge longevity and superior finishing with corrosion proof coating on the surface. They are known for their excellence in their field of working and strict maintenance of the high quality standards and specifications. These pipes are available in various shapes and sizes. There are several factors that have contributed to the popularity of these pipes over the others. And these are their various physical properties, their quite an affordable cost and many others.
Applications of Electrical Resistance Welding Pipes:
These pipes have a huge round of applications in the various fields of the industries. They are used in the engineering fields, agricultural fields etc. They are also used for fencing, line purposes of various pumps and many more. They are used to manufacture the various joints like the tees, elbows, reducers etc. in the various fittings. Also, these pipes are used for transportation of various flammable and inflammable liquids and gases for over miles and miles. They are widely used in the industrial world. This gain in popularity has resulted in the floating of the various tenders in the market through several sources. Some of them are direct from the public and the private sectors and others from the various indirect sources.. And thus these ERW pipes have provided a profitable business to the various business houses all across the world to a huge extent.
