Tubing uye Casing Coupling
Casing coupling ipombi ipfupi inoiswa mukubatanidza mapaipi maviri ane tambo.Kubatanidza pombi kune tambo dzemukati dzakagadzirwa kuti dzienderane neshinda yekunze yemajoini marefu ecasing.Iwo majoini maviri emapombi ecasing akakwenenzverwa kumativi akatarisana ecasing coupling.Kuburikidza nesimba ravo rinowanzo kugadzirwa negiredhi rimwechete resimbi senge casing.Ese casing couplings anogadzirwa zvinoenderana neAPI 5CT kutsanangurwa kweiyo yazvino edition.
Zvinhu zveCasing Couplings:
♦ Zvinhu zvekubatanidza casing ndeye H40, J55, K55, M65, N80-1, N80Q, L80, C95, T95 uye P110 giredhi simbi ine hupamhi hwepamusoro uye kuita kwakanaka;
♦ Iyo dhayamita yekunze inotangira kubva ku127mm kusvika ku365.12 mm;
♦ Mapatani eshinda anosungirirwa anosanganisira shinda pfupi yeraundi, shinda refu yakatenderera uye buttress.
Tubing coupling imhando yekuchera chishandiso inowanikwa mumunda wemafuta.Tubing couplings inonyanya kushandiswa mukubatanidza pombi dzemafuta.Rudzi urwu rwekubatana kwepombi rwakabata dambudziko rekuti matsimba aripo anowanzo kutsemuka nekuda kwekunetsekana.Pombi yemafuta inopera uye madziro emukati etubing coupling anobatanidzwa neshinda.Uye mapaipi emafuta nemigumo yetubhing coupling zvine mhando imwe chete yeshinda.Hazvisi nyore kupaza kune iyi mhando yekubatanidza uye iyo yekubatanidza maitiro yakanaka.Iyo tubing coupling inogona kudzivirira tsime remafuta tambo yekudonha tsaona zvinobudirira.
