"ERW steel pipe" is a straight seam electric resistance welded pipe, abbreviated as ERW. It is used to transport vapor and liquid objects such as oil and natural gas and can meet various requirements of high and low pressure. Currently, it occupies a pivotal position in the field of transportation p

1. Increase the temperature of natural gasIn the process of transporting natural gas, increasing the transport temperature can effectively prevent the problem of an ice blockage in long-distance steel pipelines. Generally speaking, to increase the temperature of natural gas, the main method is to in

Common methods for 3PE anti-corrosion steel pipe anti-corrosion:1. Pipeline anticorrosion generally adopts two main methods of external coating and cathodic protection.2. Although most of the surface of the pipeline is covered by the coating, a slight leak will cause an incredible corrosion rate, an
