Large-diameter line pipe starts life as plate: X-grade coils and plates are formed and seam-welded into the LSAW pipe that carries oil and gas across seabeds and continents. Pipe can only be as good as its plate — chemistry, toughness and cleanliness are locked in at the mill.
What the application demands
- API 5L X-grades (X52 through X70 and beyond) in plate form for LSAW forming
- Guaranteed low-temperature toughness for offshore and arctic service
- Sour-service options with HIC testing and hardness control to NACE MR0175
- Tight gauge control so pipe wall tolerance survives forming
Applications
LSAW pipe mills producing offshore and onshore transmission pipe, spool and fitting fabrication, and structural offshore applications where line-pipe chemistry suits the environment.
How CSACI supplies line-pipe plate
We supply line-pipe plate with the full test dossier — chemistry, tensiles, impact, and HIC where specified — under certificates of conformity and origin plus SGS third-party inspection and third-party witness as required. Tell us grade, gauge, width and tonnage and we will quote the program.
