Steel Grades and Standard for Steel Pipes

Casing pipes are used all over the world. And in different countries, there are different steel grades for tubular pipes. Like in Australia, Casing pipe is used in almost all projects.

Steel grade:
1. API 5L: A, B, X42, X46, X52, X56, X60, X65 X70 Used world widely for all petroleum pipes and piling pipes as well.
2. ASTM A 53: Gr. A, Gr B, Gr C, Gr.D This is for water pipes.
3. BS:1387, EN10217:S185, S235,S235JR, S235 G2H, S275, S275JR, S355JRH, S355J2H, St12, St13, St14, St33, St37, St44, ST52 An European standard, especially for tubular piles.
