    Isicelo

    Isetshenziswa kakhulu ukwenza insimbi yesakhiwo sekhabhoni yekhwalithi ephezulu, insimbi yesakhiwo sengxubevange kanye namapayipi ensimbi angenamthungo angangeni ekushiseni ngomfutho ophezulu kanye namapayipi abhayela wesitimu.

    Isetshenziselwa kakhulu ukucindezela okuphezulu kanye nesevisi yokushisa ephezulu ye-boiler (ishubhu ye-Superheater, ishubhu yokufudumeza kabusha, ishubhu yomhlahlandlela womoya, ishubhu lesitimu eliyinhloko lama-boilers aphezulu kanye ne-ultra high pressure). Ngaphansi kwesenzo sokushisa okuphezulu kwegesi ye-flue kanye nomhwamuko wamanzi, ithubhu izokhipha i-oxidize futhi igle. Kudingeka ukuthi ipayipi lensimbi libe nokuqina okuphezulu, ukumelana okuphezulu ne-oxidation nokugqwala, nokuzinza okuhle kwesakhiwo.

    Ubude:

    Ubude obujwayelekile bamapayipi ensimbi buyi-4 000 mm ~ 12 000 mm. Ngemva kokubonisana phakathi komphakeli nomthengi, bese ugcwalisa inkontileka, ingalethwa amapayipi ensimbi anobude obungaphezu kuka-12 000 mm noma obufushane kuno-I 000 mm kodwa angabi ngaphansi kuka-3 000 mm; ubude obufushane Isibalo samapayipi ensimbi angaphansi kuka-4,000 mm kodwa angabi ngaphansi kuka-3,000 mm angeke adlule ku-5% yenani eliphelele lamapayipi ensimbi alethiwe.

    Isisindo sokulethwa:
    Lapho ipayipi lensimbi lilethwa ngokuvumelana nobubanzi obungaphandle begama kanye nobukhulu bodonga olubizwa ngokuthiwa noma ububanzi obungaphakathi obujwayelekile kanye nobukhulu bodonga olubizwa ngokuthi, ipayipi lensimbi lilethwa ngokuvumelana nesisindo sangempela. Ingabuye ihanjiswe ngokwesisindo sethiyori.
    Lapho ipayipi yensimbi ihanjiswa ngokusho kobubanzi obungaphandle obujwayelekile kanye nobukhulu obuncane bodonga, ipayipi yensimbi ihanjiswa ngokwesisindo sangempela; amaqembu okuhlinzeka kanye nesidingo ayaxoxisana. Futhi kukhonjisiwe kunkontileka. Ipayipi lensimbi lingabuye lihanjiswe ngokuvumelana nesisindo sethiyori.

    Ukubekezelela isisindo:
    Ngokwezidingo zomthengi, ngemva kokubonisana phakathi komphakeli nomthengi, futhi kwinkontileka, ukuchezuka phakathi kwesisindo sangempela nesisindo sethiyori sepayipi lensimbi yokulethwa kuzohlangabezana nezimfuneko ezilandelayo:
    a) Ipayipi lensimbi elilodwa: ± 10%;
    b) Iqoqo ngalinye lamapayipi ensimbi anobukhulu obuncane obungama-10 t: ± 7.5%.

    Isidingo Sokuhlola

    Ukuhlolwa kwe-Hydraustatic:

    Ipayipi lensimbi kufanele lihlolwe nge-hydraulic ngayinye ngayinye. Ingcindezi yokuhlola ephezulu ingu-20 MPa. Ngaphansi kwengcindezi yokuhlola, isikhathi sokuzinza akufanele sibe ngaphansi kuka-10 s, futhi ipayipi yensimbi akufanele ivuze.

    Ngemuva kokuthi umsebenzisi evumile, ukuhlolwa kwe-hydraulic kungathathelwa indawo ukuhlolwa kwamanje kwe-eddy noma ukuhlolwa kokuvuza kazibuthe.

    Ukuhlolwa Okungonakali:

    Amapayipi adinga ukuhlolwa okwengeziwe kufanele ahlolwe nge-ultrasonically ngayinye. Ngemuva kokuthi ingxoxo idinga imvume yeqembu futhi icaciswe kunkontileka, okunye ukuhlola okungabhubhisi kungangezwa.

    Ukuhlolwa kokucaba:

    Amashubhu anobubanzi obungaphandle obukhulu kuno-22 mm azohlolwa ukuze abhebhetheke. Awekho ama-delamination abonakalayo, amabala amhlophe, noma ukungcola okufanele kwenzeke phakathi nalo lonke ucwaningo.

    Ukuhlolwa kwe-Flaring:

    Ngokwezidingo zomthengi futhi ezishiwo kunkontileka, ipayipi lensimbi elinobubanzi obungaphandle ≤76mm nokuqina kodonga ≤8mm kungenziwa ukuhlolwa kokuvutha . Ukuhlolwa kwenziwa ekamelweni lokushisa nge-taper engu-60 °. Ngemuva kokuvutha, izinga lokuvutha lobubanzi obungaphandle kufanele lihlangabezane nezidingo zetafula elilandelayo, futhi impahla yokuhlola akumele ibonise imifantu noma ukuklebhuka.
