Pajp tal-Linja
Użat għall-ġarr tal-gass, ilma u żejt kemm fl-industriji tal-gass naturali eċċ.
Casing: Il-kisi huwa pajp ta 'dijametru kbir li jservi bħala r-retainer strutturali għall-ħitan tal-bjar taż-żejt u tal-gass, jew bore. Huwa mdaħħal f'toqba sew u kkonsolidat f'posthom biex jipproteġi kemm il-formazzjonijiet ta' taħt il-wiċċ kif ukoll il-bore mill-kollass u biex jippermetti li l-fluwidu tat-tħaffir jiċċirkola u sseħħ l-estrazzjoni.Il-pajpijiet tal-kisi tal-azzar għandhom ħajt lixx u saħħa ta 'rendiment minimu ta' 35,000 psi.
Tubi: Tubi huwa pajp użat għat-trasport ta 'żejt mhux raffinat u gass naturali minn saff taż-żejt jew tal-gass għall-wiċċ wara li jitlesta t-tħaffir.Huwa magħmul biex jiflaħ il-pressjoni ġġenerata mill-proċess ta 'estrazzjoni.It-tubi huma manifatturati bl-istess mod bħall-casing, ħlief li jiġi applikat proċess addizzjonali magħruf bħala "taqlib" biex jeħxien il-pajpijiet.
