FAQ
Common questions.
ERW or seamless — which do I need?
ERW (welded) pipe is economical for water, structural and general use. Seamless pipe has no weld seam and is preferred for high-pressure, high-temperature and critical oil & gas service.
Do you supply GI pipe for plumbing and fire-fighting?
Yes — hot-dip galvanized pipe to EN 10255, ASTM A53 and IS 1239, plain-ended or threaded and socketed.
Can you supply coated line pipe?
3LPE and FBE coated line pipe can be arranged with the mill for project orders, subject to specification and quantity.
