I-Seamless Steel Pipe ngumkhiqizo wensimbi obalulekile osetshenziswa kabanzi emikhakheni eminingi. Inqubo yayo yokukhiqiza eyingqayizivele yenza ipayipi lensimbi ngaphandle kwama-welds, ngempahla engcono yemishini kanye nokuphikiswa okucindezelayo, okulungele izindawo ezinengcindezi ephezulu kanye nokushisa okuphezulu.

Mayelana nezimo zokusebenzisa, amapayipi ensimbi angenamthungo asetshenziswa kakhulu emikhakheni efana nokuhamba kwamafutha negesi, imboni yamakhemikhali, ukwakhiwa, ekwakheni, embonini yezimoto. Ikakhulu emkhakheni wamafutha negesi, amapayipi ensimbi angenamthungo ajwayele ukusetshenziselwa amapayipi kanye nemishini yokwehla, futhi angakwazi ukumelana nezimo zemvelo ezinzima.

Mayelana namazinga, amapayipi ensimbi angenamthungo ajwayele ukukhiqizwa futhi ahlolwe ngokuya ngamazinga kazwelonke (njenge-GB, ASCM, API, njll.).GB / T 8162isebenza kumapayipi ensimbi angenamthungo wezakhiwo, ngenkathiI-ASTM A106isetshenziselwa ikakhulukazi amapayipi e-carbon angenantambo angenamkhawulo wensizakalo ephezulu yokushisa. Kumapayipi ensimbi angenamthungo, amazinga ajwayelekile afakaI-ASTM A335, futhi amamaki amele angama-P5 ne-P9 ukuqinisekisa ukusebenza kwamapayipi ensimbi kumazinga okushisa athile nezingcindezi.

Ngokuya kwezinto zokwakha, amapayipi ensimbi angenamthungo ajwayele ukusebenzisa ama-alloy aphansi nama-alloy aphezulu, ngokumelana kahle nokugqwala okuphezulu, ukumelana nokushisa okuphezulu kanye nokumelana nokulimala kwe-oxidation. Isibonelo, izinto ezisetshenziswayo ezisetshenziswayo zamapayipi ensimbi ye-alloy zifaka insimbi ye-cr-moy alloy (njenge-12cr1mog njll.), Ezilungele imishini yokushisa ephezulu kanye nengcindezelo ephezulu yokushisa okufana nama-boilers kanye nokushisa okushisa. Lezi zinto zokwelashwa eziqinile zokwelashwa nokuhlolwa kokushisa ukuze kuqinisekiswe ukuqina nokuphepha kwabo ngaphansi kwezimo ezimbi kakhulu.

Amapayipi ensimbi engenamthungo, ikakhulukazi amapayipi ensimbi angenamthungo, adlale indima ebalulekile embonini yanamuhla. Ukukhiqizwa kwabo okujwayelekile kanye nezinto zokwakha eziphakeme zibenza babe ukukhetha okuhle kwezicelo ezahlukahlukene zobunjiniyela.
