Ipayipi lensimbi engenamthungo liwumkhiqizo wensimbi obalulekile osetshenziswa kabanzi emikhakheni eminingi. Inqubo yayo yokukhiqiza eyingqayizivele yenza ipayipi yensimbi ngaphandle kwama-welds, enezakhiwo ezingcono zemishini kanye nokumelana nokucindezela, ezifanele izindawo ezinomfutho ophezulu kanye nokushisa okuphezulu.

Ngokwezimo zokusetshenziswa, amapayipi ensimbi angenamthungo avame ukusetshenziswa emikhakheni efana nokuthuthwa kukawoyela negesi, imboni yamakhemikhali, ukwakhiwa, ukwakhiwa kwemikhumbi kanye nemboni yezimoto. Ikakhulukazi embonini kawoyela negesi, amapayipi ensimbi angenamthungo avame ukusetshenziselwa amapayipi kanye nemishini yokukhipha amanzi, futhi angakwazi ukumelana nezimo zemvelo ezinzima.

Ngokuphathelene nezindinganiso, amapayipi ensimbi angenamthungo ngokuvamile akhiqizwa futhi ahlolwe ngokuvumelana nezindinganiso zikazwelonke (ezifana ne-GB, ASTM, API, njll.).I-GB/T 8162iyasebenza kumapayipi ensimbi angenamthungo wezakhiwo, ngenkathiI-ASTM A106isetshenziswa ikakhulukazi carbon steel amapayipi Seamless for izinga lokushisa eliphezulu service. Ngamapayipi ensimbi angenasici, izindinganiso ezivamile zihlanganisaI-ASTM A335, futhi amamaki amele i-P5 ne-P9 ukuqinisekisa ukusebenza kwamapayipi ensimbi emazingeni okushisa athile kanye nezingcindezi.

Ngokuphathelene nezinto zokwakha, amapayipi ensimbi angenamthungo ngokuvamile asebenzisa i-alloy ephansi nezinsimbi eziphezulu ze-alloy, ezinokumelana nokugqwala okuhle kakhulu, ukumelana nokushisa okuphezulu kanye nokumelana ne-oxidation. Isibonelo, izinto ezisetshenziswa kakhulu zamapayipi ensimbi ye-alloy zifaka insimbi ye-Cr-Mo alloy (efana ne-12Cr1MoG njll.), ezifanele imishini yokushisa ephezulu kanye ne-high-pressure efana nama-boilers kanye nezishintshi zokushisa. Lezi zinto zithola ukwelashwa okushisa okuqinile nokuhlolwa ukuze kuqinisekiswe ukuzinza nokuphepha kwazo ngaphansi kwezimo ezimbi kakhulu.

Amapayipi ensimbi angenamthungo, ikakhulukazi amapayipi ensimbi angenamthungo, adlala indima ebalulekile embonini yesimanje. Ukukhiqizwa kwabo okujwayelekile kanye nezinto ezisezingeni eliphakeme kubenza babe ukukhetha okuhle kwezicelo ezahlukahlukene zobunjiniyela.
