Steel Pipe Grades and Standard

Casing pipes are widely used in Australian local projects.

The common Steel grade requirements are:
1. API 5L: A, B, X42, X46, X52, X56, X60, X65 X70       Used worldwide for petroleum pipes and piling pipes.
2. ASTM A 53: Gr. A, Gr B, Gr C, Gr.D                         Typical 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.
4. AS1163 :C250,C350,C450, C250L0, C350L0, C450L0    Australia and New Zealand standard.
