Tubing Pup Joint
Tubing mfundo za pup amagwira ntchito ngati gawo lofunika kwambiri pamakampani amafuta ndi gasi, kulumikiza magawo osiyanasiyana a machubu palimodzi kuti apange kuyenda kosasunthika kwamafuta ndi gasi kuchokera pankhokwe kupita pamwamba. Malumikizidwewa adapangidwa kuti azitha kusinthasintha komanso kukana kukakamizidwa, kulola kuyendetsa bwino zinthu kudzera pachitsime. Cholumikizira cha chubu chimagwira ntchito ngati cholumikizira pakati pa chingwe chachikulu cha chubu ndi zida zina zomalizitsira, kuonetsetsa kuti ali ndi chisindikizo cholimba kuti asatayike kapena kutayika kwa kupanga. Pokhala ndi kuthekera kokhala ndi makulidwe osiyanasiyana ndi mawonekedwe, machubu a pup amathandizira kwambiri kukhathamiritsa bwino komanso kusunga magwiridwe antchito pakupanga mafuta ndi gasi.
Machubu a pup amatenga gawo lofunikira kwambiri pamsika wamafuta ndi gasi, amagwira ntchito ngati zolumikizira pakati pa magawo awiri a chubu. Machubu afupikitsawa amagwiritsidwa ntchito kusintha kutalika kwa chingwe cha chubu kapena kupatula gawo linalake la chitsime. Nthawi zambiri amapezeka m'masaizi osiyanasiyana komanso masinthidwe kuti akwaniritse zosowa zosiyanasiyana. Magulu a ana ang'onoang'ono amapangidwa ndi timabowo ting'onoting'ono m'litali mwa chubu, zomwe zimapangitsa kuti madzi azilowa ndi kutuluka m'chitsime. Kapangidwe kameneka kamakhala kothandiza kwambiri pakugwiritsa ntchito mchenga kapena tinthu tating'ono tomwe timayenera kusefedwa kuchokera kumadzi opangidwa. Pogwiritsa ntchito ma perforated pup joints, ogwira ntchito amatha kuteteza kutsekeka ndikuwonetsetsa kuyenda bwino. Kuphatikiza apo, zolumikizira za ana agaluzi zitha kukhazikitsidwa mosavuta ndikuchotsedwa ngati pakufunika, kupereka kusinthasintha komanso magwiridwe antchito bwino. Ponseponse, machubu a machubu, makamaka omwe ali ndi perforated, ndizofunikira kwambiri pakupanga chitsime chamafuta ndi gasi, kupititsa patsogolo magwiridwe antchito komanso kudalirika.
API 5CT ndi muyezo wopangidwa ndi American Petroleum Institute womwe umakhazikitsa malangizo opangira ndi kuyesa zinthu za tubular zomwe zimagwiritsidwa ntchito pamakampani, kuwonetsetsa kuti ndi zodalirika komanso zodalirika.
