Payment & Shipping Terms:
N80-Q grade is much higher than N80-1 grade, which requires to be given heat treatment ( normalizing +tempering) in order to achieve the mechanical properties .
N80-Q seamless casing pipes can be used in drilling projects, oil /water wells, constructions,.
Sometimes impact test should be done under -20 degree if necessary.

--Length: R3 ( or required such as 9-12m)
--Surface of pipe body: bare, no black vanish
--Marking: as per API 5CT or customer’s request
--Packing: in bundles with steel strips, 3MT/BUNDLE
--TPI: Third Party Inspection can be done before shipment and testing costs will be in seller’s account.
Extra Technical Processing: 2 drilling holes will be given on one of the pipe ends. The distance between these
2 holes is the diameter of the pipe. More importantly, these 2 holes must be symmetrical.
Note: We, Borun as a group company, are mainly dealing with OCTG, SMLS PIPE , Hollow Section as well as
other steel profiles.
