Ipayipi lensimbi elingenamthungo liwumkhiqizo wensimbi obalulekile osetshenziswa kabanzi emikhakheni eminingi. Inqubo yalo yokukhiqiza eyingqayizivele yenza ipayipi lensimbi lingenazo izindwangu zokushisela, elinezakhiwo ezingcono zemishini kanye nokumelana nokucindezela, lifaneleke ezindaweni ezinengcindezi ephezulu kanye nokushisa okuphezulu.

Ngokuphathelene nezimo 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 yokudonsa phansi, futhi angamelana nezimo zemvelo ezinzima.

Ngokuphathelene nezindinganiso, amapayipi ensimbi angenamthungo avame ukukhiqizwa futhi ahlolwe ngokuhambisana nezindinganiso zikazwelonke (njenge-GB, i-ASTM, i-API, njll.).I-GB/T 8162kusebenza kumapayipi ensimbi angenamthungo ezakhiweni, kuyilaphoI-ASTM A106isetshenziswa kakhulu kumapayipi angenamthungo ensimbi yekhabhoni ukuze kusetshenziswe izinga lokushisa eliphezulu. Kumapayipi ensimbi angenamthungo e-alloy, amazinga avamile afaka phakathiI-ASTM A335, futhi amazinga amele yi-P5 kanye ne-P9 ukuqinisekisa ukusebenza kwamapayipi ensimbi emazingeni okushisa athile kanye nokucindezela.

Ngokuphathelene nezinto zokwakha, amapayipi ensimbi angenamthungo avame ukusebenzisa izinsimbi ze-alloy eziphansi kanye nezinsimbi ze-alloy eziphezulu, ezinokumelana okuhle kakhulu nokugqwala, ukumelana nokushisa okuphezulu kanye nokumelana ne-oxidation. Isibonelo, izinto ezisetshenziswa kakhulu kumapayipi ensimbi ye-alloy zifaka insimbi ye-Cr-Mo (njenge-12Cr1MoG njll.), ezifanele imishini yokushisa okuphezulu kanye nengcindezi ephezulu njengama-boilers kanye nama-heat exchanger. Lezi zinto ziphathwa ngokushisa okunzima futhi zihlolwa ukuqinisekisa ukuzinza nokuphepha kwazo ngaphansi kwezimo ezimbi kakhulu.

Amapayipi ensimbi angenamthungo, ikakhulukazi amapayipi ensimbi ahlanganisiwe angenamthungo, adlala indima ebalulekile embonini yanamuhla. Ukukhiqizwa kwawo okujwayelekile kanye nezinto zokwakha ezisezingeni eliphezulu kuwenza abe ukukhetha okuhle kwezicelo ezahlukahlukene zobunjiniyela.
