The standard API 5L is the specification line pipe. The grade API 5L GrB is one of the materials in the standard API 5L. API 5L GrB not only can produced into steel pipe, but can produced into API 5L GrB steel plate. API 5LGrB steel plate, API 5L GrB pipes is one mainly of steel for large diameter pipes. API-GrB steel is manufactured using premium grade of raw material. These are used to flow steam, water, oil and various petrochemicals substance in various petrochemical and chemical industries. These steel seamless pipes are widely appreciated for high performance and less maintenance.
