Our pipeline products adopt the national standard and the international standard API 5L, which can meet the needs of A573 Gr 70 structural carbon steel sheet pipelines working in different environments-on land in the open air and offshore deep water. Acid
Our pipeline products adopt the national standard and the international standard API 5L, which can meet the needs of A573 Gr 70 structural carbon steel sheet pipelines working in different environments-on land in the open air and offshore deep water. Acid-resistant pipelines are produced for transporting highly acidic crude oil.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of A573 Gr 70 structural carbon steel sheet, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).
We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
