Tubing Pup Joint
Litholoana tsa li-tubing pup e sebetsa e le karolo ea bohlokoa indastering ea oli le khase, e hokahanyang likarolo tse fapaneng tsa liphaephe hammoho ho theha phallo e se nang moeli ea oli le khase ho tloha letamong ho ea holimo. Manonyeletso ana a etselitsoe ho fana ka ho feto-fetoha ha maemo le ho hanyetsa khatello, ho lumella ho tsamaisoa hantle ha lisebelisoa ka seliba. Lenonyeletso la tubing pup le sebetsa e le sehokedi pakeng tsa thapo e kgolo ya tubing le disebediswa tse ding tsa ho phethela, ho netefatsa tiiso e tiileng ho thibela ho dutla kapa tahlehelo efe kapa efe ya tlhahiso. Ka bokhoni ba ho amohela boholo le litlhaloso tse fapaneng, li-tubing pup joints li bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso e ntle le ho boloka ts'ebetso e sebetsang hantle tlhahisong ea oli le khase.
Li-tubing pup joints li phetha karolo ea bohlokoa indastering ea oli le khase, li sebetsa e le likhokahano lipakeng tsa likarolo tse peli tsa li-tubing. Bolelele bona bo bokhutšoane ba li-tubing bo sebelisetsoa ho lokisa bolelele ba likhoele tsa tubing ka kakaretso kapa ho arola karolo e itseng ea seliba. Ka tloaelo li fumaneha ka boholo bo fapaneng le litlhophiso ho fihlela litlhoko tse fapaneng tsa ts'ebetso. Manonyeletso a pup a entsoe ka masoba a manyane ho latela bolelele ba tubing, a lumellang hore mokelikeli o kene le ho tsoa selibeng. Moralo ona o bohlokoa haholo lits'ebetsong moo lehlabathe kapa likaroloana tse tiileng li hlokang ho tlhotloa ho tsoa mokelikeli o hlahisoang. Ka ho sebelisa li-perforated pup joints, basebetsi ba ka thibela li-blockages le ho netefatsa hore tlhahiso e phalla hantle. Ho feta moo, manonyeletso ana a li-pup a ka kenngoa habonolo le ho tlosoa ha ho hlokahala, a fana ka bonolo le ts'ebetso ea ts'ebetso ea liliba. Ka kakaretso, manonyeletso a li-tubing pup, haholo-holo a nang le libotlolo, ke likarolo tsa bohlokoa tlhahisong ea liliba tsa oli le khase, tse matlafatsang ts'ebetso le ts'epahalo.
API 5CT ke tekanyetso e ntlafalitsoeng ke American Petroleum Institute e behang litataiso bakeng sa tlhahiso le tlhahlobo ea thepa e sebelisoang indastering, ho netefatsa boleng ba tsona le ts'epahalo ea tsona.
