API 5L GR.B ERW pipes

API 5L GR.B ERW pipes

API 5L ERW steel pipe is an electric resistance welding (ERW) steel pipe that complies with the American Petroleum Institute (API) standard API 5L specification. This type of steel pipe is commonly used to transport liquids and gases such as oil and natural gas. The API 5L standard stipulates the requirements for the size, chemical composition, mechanical properties and manufacturing process of steel pipes to ensure the safety and reliability of the pipes during use. The ERW manufacturing process is a process in which steel sheets are rolled into a tubular shape and then resistive heating and pressure are used to weld the edges of the steel sheets to form the tubes. API 5L ERW steel pipe has the advantages of low production cost, high production efficiency and simple manufacturing process, and is widely used in the oil and gas industry.

In order to meet the needs of our customers, we not only customized the production of steel pipes as required, but also provided services such as black painting on the surface of the steel pipe, dimensional inspection, coating thickness inspection, and piping caps at both ends. These strict quality control measures ensure the quality and reliability of steel pipes.

Haihao Group’s efficient production plan enables us to complete production and deliver on time within a 20-day lead time. Our production team has started production on April 10th and will complete the production and delivery of all orders before the end of the month.

The successful signing of this order once again proves Haihao Group’s technical strength and professional services in the field of pipeline systems. We will continue to be committed to providing customers with high-quality products and services and becoming a trustworthy partner for customers.
