    I-API 5L 46th Edition Decation for Line Pipe
    • I-API 5L 46th Edition Decation for Line Pipe Scope

    Incazelo emfushane:

    Kucaciswe ukwenziwa kwamazinga womkhiqizo amabili (PSL1 nePSL2) yepayipi lensimbi engenamthungo nelishisiwe lokusebenzisa ipayipi lapho kwezokuhamba kaphethiloli kanye nemvelo yemvelo. Ukusetshenziswa ngokwezinto ezibonakalayo ohlelweni lokusebenza lwensiza emuncu bhekisisa ku-Annex H nohlelo lwe-Offshore Service bhekisisa ku-Annex j we-API5L 45th.

    Okumahle (r, n, q noma m) kumabanga we-PSL2, kungokwaba ngebanga lensimbi

    Uku-oda imininingwane

    I-oda lokuthenga lizofaka inani, izinga le-PSL, uhlobo noma ibanga, ireferensi ku-Api5l, ububanzi obungaphandle, ubude bokushisa, ukwelashwa okwengeziwe, inqubo yokukhiqiza, ukuqedwa okungaphezulu.

    Ukuqala Kwezinto

    Ama-Ingots, ama-blooms, ama-billts, amakhoyili noma amapuleti asetshenziselwa ukwenziwa kwepayipi azokwenziwa ngezinqubo ezilandelayo, umoya ophefumulayo oyisisekelo, umoya ovulekile ngokuhlanganiswa nenqubo yokucwengwa kweLadi. Kwe-PSL2, insimbi izobulawa futhi incibilikiswe ngokwemikhuba yokusanhlamvu enhle. I-Coil noma ipuleti elisetshenziselwe ipayipi le-PSL2 ngeke liqukethe noma yiziphi izinsimbi zokulungisa.

    Ukuhlolwa kweHydrostatic

    Ipayipi lokumelana nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi. Ama-pailers akudingeki ukuthi ahlolwe ama-hydrostatic ahlinzeke ngezingxenye zamapayipi asetshenziswa ngempumelelo.

    Ukuhlolwa kwe-Bend

    Akukho ukuqhekeka okuzokwenzeka kunoma iyiphi ingxenye yocezu lokuhlola nokungavuli kwe-weld kuzokwenzeka.

    Ukuhlolwa okumnandi

    Izindlela zokwamukela zokuhlolwa okuvuthayo kuzoba njalo
    a) Amapayipi e-EW d <12.750 in
    -≥ x60 nge-t≥.500in, ngeke kube khona ukuvulwa kwe-weld ngaphambi kwebanga phakathi kwamapuleti kungaphansi kwama-66% wobubanzi obungaphandle kwe-66%. Kuwo wonke amabanga nodonga, ama-50%.
    -Kopha ipayipi nge-D / T> 10, ngeke kube khona ukuvulwa kwe-weld ngaphambi kwebanga phakathi kwamapuleti kungaphansi kwama-30% wobubanzi obungaphandle.
    b) Kwamanye amasayizi abhekisela kwi-Full API5L ecacisiwe

    I-CVN Impact Test ye-PSL2

    Amasayizi amaningi ama-PPL2 Pipe namamaki adinga i-CVN. Ipayipi elingenamthungo kufanele lihlolwe emzimbeni. Ipayipi le-Welded lizohlolwa emzimbeni, ipayipi we-weld kanye nokushisa kwendawo ethintekile (haz). Bheka imininingwane ephelele ye-API5L yeshadi lamasayizi namabanga kanye namanani wamandla adingekayo.
