Can X56 pipe be supplied in sour service?

Yes, when ordered as PSL2 with NACE MR0175 chemistry controls and HIC/SSC testing.

What is the minimum order quantity?

MOQ depends on size and coating; Mumbai stock allows smaller cut-length quantities than mill-direct orders.

Do you supply both seamless and ERW X56 pipe?

Yes, both processes are stocked and can also be sourced to project-specific sizes on indent.

What documents come standard with every shipment?

Mill Test Certificate, packing list and certificate of origin are provided as standard; TPI and NACE reports are available on request.
