Pipa Line
Digunakake kanggo ngirim gas, banyu, lan lenga ing loro lan industri gas alam etc.
Casing: Casing minangka pipa kanthi diameter gedhe sing dadi penahan struktural kanggo tembok sumur minyak lan gas, utawa sumur sumur. kanggo ngidini cairan pengeboran sirkulasi lan ekstraksi bisa ditindakake.Pipa Casing Baja nduweni tembok alus & kekuatan ngasilake minimal 35.000 psi.
Tubing: Tubing yaiku pipa sing digunakake kanggo transportasi minyak mentah lan gas alam saka lapisan minyak utawa gas menyang permukaan sawise pengeboran rampung.Iki digawe kanggo nahan tekanan sing diasilake saka proses ekstraksi.Tubing diprodhuksi kanthi cara sing padha karo casing, kajaba proses tambahan sing dikenal minangka "upsetting" ditrapake kanggo nglukis pipa.
