Khase ea oli ea APIke phala ea tšepe e sebelisetsoang ho tšehetsa lerako la liliba tsa oli le khase ho netefatsa ts'ebetso e tloaelehileng ea seliba sohle sa oli nakong ea ho cheka le ka mor'a ho phethoa.

Teko ea khatello ea hydrostatic ea pipe ea casing ke karolo ea bohlokoahali ea ts'ebetso ea tlhahiso ea phala ea tšepe. Mosebetsi oa eona ke ho lekola ts'ebetso ea anti-leakage ea pipe ea tšepe tlas'a khatello e tloaelehileng ea teko le nako ea taolo. Joalo ka li-radiographs, ultrasonics, le mekhoa e meng ea ho lemoha liphoso, ke mokhoa oa bohlokoa oa ho lekola boleng ba kakaretso ba li-tubes tsa tšepe.

Tlhaloso e tsebahalang ke ho tlatsa phala ka metsi le ho leka bokhoni ba eona ba ho boloka khatello e boletsoeng ntle le ho phalla kapa ho senya tlas'a khatello. Ts'ebetso ea eona e kenyelletsa mehato e meraro: ho hlatsoa metsi, tlhahlobo ea khatello le taolo ea metsi.

Tekanyetso ea API 5CT bakeng sa tlhahlobo ea khatello ea hydrostatic:

1. Boleng ba tlhahlobo ea khatello ea hydrostatic ea coupling le phala ea threaded ke boleng bo tlaase ka ho fetisisa ba khatello ea teko ea hydrostatic ea pipe ea ho qetela e bataletseng, khatello e phahameng ea hydrostatic khatello ea teko ea ho kopanya, le ho hanyetsa khatello ea ka hare ea ho lutla, empa khatello e phahameng e tloaelehileng ke. 69MPa mme khatello e baloa. Boleng ka kakaretso bo pota-potiloe ho 0.5 MPa e haufi.
2. Ho ea ka litlhoko tsa API, mochine oa ho lekanya khatello ea teko ea hydrostatic o lokela ho lekanyetsoa ka hare ho likhoeli tsa 4 pele o sebelisoa.
3. Haeba moreki a e-na le litlhoko tse khethehileng, khatello e phahameng ea teko ea khatello e ka khethoa.
4. Hydrostatic khatello ea teko Leakage ke motheo oa ho hana.
5. Ntle le moo ho lumellanoeng ka tsela e 'ngoe pakeng tsa moreki le moetsi, tlhahlobo ea khatello ea hydrostatic ha e hlokehe bakeng sa ho kopanya likheo, lisebelisoa tsa ho kopanya, lisebelisoa tse haufi, kapa li-pup tsa tšepe tsa Q125.
