Carbon Steel Weld Pipe ERW Black Steel Pipe Used For Liquid Delivery

The manufacturing process of the steel pipes
The ERW Black Steel Pipes are manufactured by experienced and highly skilled workers. These pipes are developed by the superior quality of raw material which is collected from the reliable market place. All the material collected is tested before use to avoid the poor quality of substances to mix in the manufacturing of the pipes. The manufacturing process is carried out under the strict supervision of the hired expert who has an excellent knowledge about the manufacturing of the pipes.

For their smooth finish and excellent workability, the pipes move through various stages in the production process. These pipes are developed as per the demand of the clients and all the guidelines are followed that are stated by the customers.

Quality assurance and material testing
The main aim is to provide the superior quality of the pipes that are provided to the well-esteemed clients. Quality of the pipes is checked at every stage of the manufacturing process. During the development of the pipes, all the well stated manufacturing norms are followed. All the national and international set of quality standards are kept in analyzing the quality of the Carbon Steel ERW Black Steel Pipes.

The quality checkers conducts different tests to check the quality of the pipes that are manufactured to avoid last stage delays in delivery of the product. Conduction of tests ensures the clients about the safely manufacturing of the product that they are provided with. The various tests that they conduct are hardness test, hydrostatic test, ultrasonic test, intergranular corrosion test, positive material test, and flattening test.
