Ubude:
Ubude obujwayelekile bamapayipi ensimbi bungu-4 000 mm ~ 12 000 mm. Ngemva kokubonisana phakathi komhlinzeki nomthengi, nokugcwalisa inkontileka, kungalethwa amapayipi ensimbi anobude obungaphezu kuka-12 000 mm noma afushane kuno-1 000 mm kodwa angabi mafushane kuno-3 000 mm; ubude obufushane Inani lamapayipi ensimbi angaphansi kuka-4,000 mm kodwa angabi ngaphansi kuka-3,000 mm akumele lidlule u-5% wenani eliphelele lamapayipi ensimbi alethwayo.
Isisindo sokulethwa:
Uma ipayipi lensimbi lilethwa ngokwesilinganiso sangaphandle esilinganiselwe kanye nobukhulu bodonga obulinganiselwe noma ububanzi bangaphakathi obulinganiselwe kanye nobukhulu bodonga obulinganiselwe, ipayipi lensimbi lilethwa ngokwesisindo sangempela. Lingalethwa futhi ngokwesisindo esicatshangelwayo.
Uma ipayipi lensimbi lilethwa ngokwesilinganiso sangaphandle kanye nobukhulu bodonga obuncane, ipayipi lensimbi lilethwa ngokwesisindo sangempela; amaqembu okuphakelwa kanye nesidingo ayaxoxisana. Futhi kuboniswe esivumelwaneni. Ipayipi lensimbi lingalethwa futhi ngokwesisindo esisekelwe emcabangweni.
Ukubekezelelana kwesisindo:
Ngokwezidingo zomthengi, ngemva kokubonisana phakathi komhlinzeki nomthengi, kanye nasenkontilekeni, ukuphambuka phakathi kwesisindo sangempela kanye nesisindo esingokomqondo sepayipi lensimbi yokulethwa kuzohlangabezana nezidingo ezilandelayo:
a) Ipayipi lensimbi elilodwa: ± 10%;
b) Iqoqo ngalinye lamapayipi ensimbi anosayizi omncane ongu-10 t: ± 7.5%.
Ukuhlolwa kwe-Hydraustatic:
Ipayipi lensimbi kufanele lihlolwe ngamanzi ngamunye ngamunye. Ingcindezi ephezulu yokuhlola ingu-20 MPa. Ngaphansi kwengcindezi yokuhlola, isikhathi sokuzinza akufanele sibe ngaphansi kwamasekhondi ayi-10, futhi ipayipi lensimbi akufanele livuze.
Ngemva kokuba umsebenzisi evumile, ukuhlolwa kwe-hydraulic kungathathelwa indawo ukuhlolwa kwe-eddy current noma ukuhlolwa kokuvuza kwe-magnetic flux.
Ukuhlolwa Okungabhubhisi:
Amapayipi adinga ukuhlolwa okwengeziwe kufanele ahlolwe nge-ultrasound ngalinye ngalinye. Ngemva kokuba ingxoxo idinga imvume yeqembu futhi ichazwe enkontilekeni, kungangezwa okunye ukuhlolwa okungonakalisi.
Ukuhlolwa Kokuthamba:
Amapayipi anobubanzi bangaphandle obungaphezu kwama-22 mm azohlolwa ngokulinganisela. Akukho ukuhlukaniswa okubonakalayo, amabala amhlophe, noma ukungcola okufanele kwenzeke phakathi nalo lonke ucwaningo.
Ukuhlolwa Kokuvutha:
Ngokwezidingo zomthengi futhi ezishiwo kwinkontileka, ipayipi lensimbi elinobubanzi bangaphandle obungu-≤76mm kanye nobukhulu bodonga obungu-≤8mm lingenziwa ukuhlolwa kokuvutha. Ukuhlolwa kwenziwe ekushiseni kwegumbi nge-taper engu-60 °. Ngemva kokuvutha, izinga lokuvutha kobubanzi bangaphandle kufanele lihlangabezane nezidingo zethebula elilandelayo, futhi izinto zokuhlola akumele zibonise imifantu noma ukuklebhuka.
