Confirm actual production route and standard before specifying carbon pipe for fluid service.
Route conflict
The title requests ERW while the detail names ERW, EFW and GMAW techniques and a seamless round type. Agree actual manufacture and applicable A53 or A500 requirements rather than treating all routes as one verified compliant pipe.
Schedule and wall
The actual wall option is custom and lengths are 6 or 12 m without outside diameter. Define OD, nominal convention and schedule 40 or 80 applicability with a compatible measured wall and selected black non-oiled surface.

Application acceptance
Water, gas, steam and BIS certified wording provide no verified approval result. Request actual material and design records; no potable water approval, pressure capability, steam temperature rating or certification is established.
