Amapayipi ensimbi angenamthungo ngokuvamile adinga ukupendwa futhi aboshwe ngaphambi kokuphuma embonini. Lezi zinyathelo zokucubungula ezokuthuthukisa ukusebenza kwamapayipi ensimbi futhi zivumelane nezidingo ezahlukene zobunjiniyela.

Inhloso eyinhloko yokudweba ukuvimbela amapayipi ensimbi ukuthi angagqwali futhi agxumeke ngesikhathi sokugcina nokuthutha. Ukudweba kungenza ifilimu yokuzivikela ebusweni bepayipi yensimbi, ihlukanise umoya nomswakama, futhi yandise impilo yesevisi yepayipi yensimbi. Ukudweba kubaluleke kakhulu kumapayipi ensimbi adinga ukugcinwa isikhathi eside noma asetshenziswe ezindaweni ezinomswakama.

Ukwelashwa kwe-bevel ukwenza lula ukushiselwa kwamapayipi ensimbi. Amapayipi ensimbi angenamthungo ngokuvamile adinga ukushiselwa lapho exhunyiwe. I-Bevel ingandisa indawo yokushisela futhi iqinisekise ukuqina nokubekwa uphawu kwe-weld. Ikakhulukazi ezinhlelweni zamapayipi asetshenziswa ezindaweni ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu, ukwelashwa kwe-bevel kungathuthukisa kakhulu ikhwalithi yokushisela futhi kuvimbele ukuvuza nokugqabuka.

Ukuze uthole izindinganiso ezithile zamapayipi ensimbi angenamthungo, njengeI-ASTM A106, I-ASME A53futhiI-API 5L, izindlela zokwelapha ezilandelayo ziyadingeka ngesikhathi sokucubungula:

Ukusika: Sika ubude obudingekayo ngokwezidingo zekhasimende.
Ukudweba: Faka upende ovimbela ukugqwala ebusweni bepayipi lensimbi.
Bevel: Ukwelashwa kwe-bevel kwenziwa njengoba kudingekile, ngokuvamile kufaka phakathi ama-bevel amise okwe-V kanye nakabili amise okwe-V.
Ukuqondisa: Qinisekisa ubuqotho bepayipi lensimbi ukuze kube lula ukufakwa nokusetshenziswa.
Ukuhlolwa kwe-Hydrostatic: Yenza ukuhlolwa kwe-hydrostatic epayipini lensimbi ukuze uqinisekise ukuthi lingakwazi ukumelana nokucindezela okucacisiwe futhi lihlangabezane nezindinganiso zokuphepha.
Ukutholwa kwamaphutha: Sebenzisa izindlela zokuhlola ezingalimazi njenge-ultrasound ne-X-ray ukuze uhlole ukonakala kwangaphakathi kwepayipi lensimbi ukuze uqinisekise ikhwalithi yalo.
Ukumaka: Maka ukucaciswa komkhiqizo, izindinganiso, ulwazi lomkhiqizi, njll. ebusweni bepayipi lensimbi ukuze kulandeleke kalula nokuphathwa.
Lezi zinyathelo zokucubungula ziqinisekisa ukwethembeka nokuphepha kwamapayipi ensimbi angenasici ekusetshenzisweni okuhlukahlukene futhi ahlangabezane nezidingo eziqinile zamapayipi ensimbi emikhakheni yezimboni ezahlukene.
