API oiri casingipombi yesimbi inoshandiswa kutsigira madziro emafuta uye gasi matsime kuti ave nechokwadi chekushanda kwakajairika kwetsime remafuta panguva yekuchera uye mushure mekupedzwa.

Iyo hydrostatic pressure test yecasing pombi chikamu chakakosha chekugadzirwa kwepombi yesimbi. Basa rayo ndere kuyedza iyo anti-leakage kuita kwepombi yesimbi pasi peyakajairwa bvunzo kumanikidza uye nguva yekutonga. Kufanana neradiographs, ultrasonics, uye mamwe maitiro ekuona kukanganisa, inzira yakakosha yekuyedza huwandu hwese hwemachubhu esimbi.

Tsanangudzo yakakurumbira ndeyekuzadza pombi nemvura uye kuyedza kugona kwayo kuchengetedza kudzvanywa kwakatarwa pasina kubuda kana kutyora pasi pekumanikidzwa. Mashandiro ayo anosanganisira matanho matatu: kugezesa, kuyera kudzvanywa uye kutonga kwemvura.

API 5CT chiyero che hydrostatic pressure test:

1. Iyo hydrostatic pressure test value yekubatanidza uye threaded pombi ndiyo yakaderera kukosha kweiyo hydrostatic test pressure ye flat end pombi, iyo yakanyanya hydrostatic pressure test pressure yekubatanidza, uye yemukati pressure leakage resistance, asi mwero wakanyanya kudzvanywa 69MPa uye kudzvanywa kunoverengerwa. Kukosha kunowanzo kutenderedzwa kune iri pedyo 0.5 MPa.
2. Maererano nezvinodiwa neAPI, iyo hydrostatic test pressure yekuyera mudziyo inofanira kuenzaniswa mukati memwedzi ye4 imwe neimwe isati yashandiswa.
3. Kana mutengi ane zvakakosha zvinodiwa, chiyero chepamusoro chekuedza kudzvinyirira chinogona kusarudzwa.
4. Hydrostatic pressure test Leakage ndiyo hwaro hwekurambwa.
5. Kunze kwekunge kwakabvumiranwa neimwe nzira pakati pemutengi nemugadziri, hydrostatic pressure testing haidiwi pakubatanidza mablanks, coupling materials, zvinhu zviri pedyo, kana Q125 steel pup joints.
