Ubude:
Ubude obujwayelekile bamapayipi ensimbi ngu-4 000 mm ~ 12 000 mm. Ngemuva kokubonisana phakathi komphakeli nomthengi, bese ugcwalisa inkontileka, ingahanjiswa amapayipi ensimbi ngobukhulu obukhulu kune-12 000 mm noma mfushane kunami 000 mm; Ubude obufushane Inombolo yamapayipi ensimbi angaphansi kwama-4,000 mm kepha angaphansi kwama-3,000 mm ngeke adlule ama-5% enani eliphelele lamapayipi ensimbi alethwe
Isisindo Sokulethwa:
Lapho ipayipi lensimbi lihanjiswa ngokuya nge-auworinal andeter ububanzi kanye nobubanzi obungodonga noma ububanzi be-inner benter kanye nobubanzi bensimbi ethosiwe, ipayipi lensimbi lihanjiswa ngokuya ngesisindo sangempela. Kungalethwa futhi ngokuya ngesisindo sethiyori.
Lapho ipayipi lensimbi lihanjiswa ngokuya ngobubanzi obungaphandle obungaphandle nobuncane obuncane udonga, ipayipi lensimbi lihanjiswa ngokwesisindo sangempela; ukuhlinzekwa kanye nokufuna amaqembu axoxisane. Futhi kukhonjisiwe kwinkontileka. Ipayipi lensimbi lingahanjiswa futhi ngokuya ngesisindo sethiyori.
Ukubekezelela isisindo:
Ngokwezidingo zomthengi, ngemuva kokubonisana phakathi komphakeli kanye nomthengi, nakwinkontileka, ukuphambuka phakathi kwesisindo sangempela kanye nesisindo se-theory sepayipi lensimbi lizohlangabezana nalezi zidingo ezilandelayo:
a) ipayipi lensimbi eyodwa: ± 10%;
b) I-batch ngayinye yamapayipi ensimbi anosayizi omncane we-10 t: ± 7.5%.
Ukuhlolwa kweHydraustatic:
Ipayipi lensimbi kufanele lihlolwe nge-hydraulically ngamunye ngamunye. Ingcindezi yokuhlola ephezulu yi-20 MPA. Ngaphansi kwengcindezi yokuhlola, isikhathi sokuqina kufanele singabi ngaphansi kwama-10 s, futhi ipayipi lensimbi akufanele livuze.
Ngemuva kokuthi umsebenzisi avume, ukuhlolwa kwe-Hydraulic kungathathelwa indawo ukuhlolwa kwangaphambi kokuhlolwa kwamanje noma ukuhlolwa kwamandla kazibuthe.
Ukuhlolwa Okungahambi kahle:
Amapayipi adinga ukuhlolwa okuningi kufanele ahlolwe ngo-ultrasonically ngamunye. Ngemuva kokuthi izingxoxo zidinga imvume yephathi futhi zichaziwe kwinkontileka, okunye ukuhlola okungeyona eyonakalisayo kungangezwa.
Ukuhlolwa okumnandi:
Amashubhu anesilinganiso esingaphandle esingama-22 mm azofakwa ngaphansi kokuhlolwa okumnandi. Akukho ukuncipha okubonakalayo, izindawo ezimhlophe, noma ukungcola kufanele zenzeke kulo lonke ucwaningo.
Ukuhlolwa okuthe xaxa:
Ngokwezidingo zomthengi futhi zichazwe kwinkontileka, ipayipi lensimbi eline-outer ububanzi ≤76mm kanye nodonga ubukhulu ≤8mm kungenziwa ukuhlolwa okuvuthayo. Ukuhlolwa kwenziwa egumbini lokushisa lasekamelweni nge-TAPER ka-60 °. Ngemuva kokuvutha, izinga elivuthayo lebubanzi obungaphandle kufanele lihlangabezane nezidingo zethebula elilandelayo, futhi izinto zokuhlola akufanele zikhombise imifantu noma ama-rips
