    test Hydrostatic

    Pipe ukumelana uvavanyo hydrostatic ngaphandle ukuvuza ngokusebenzisa umthungo weld okanye umzimba umbhobho. Jointers mfuneko yokuba ube hydrostatic avavanywe zinika amacandelo umbhobho kusetyenziswa zavavanywa ngempumelelo.

    Bend test

    Akukho iintanda ziya kwenzeka nayiphi na inxalenye piece uvavanyo kunye akukho ukuvulwa weld iya kwenzeka.

    Flattening test

    Iikhrayitheriya Ukwamkelwa ngokuba flattening uvavanyo iya kuba:

    • W. imibhobho D <12,750 ngo:
    • X60 ne T 500in. Akuyi kubakho ukuvulwa weld phambi kokuba umgama phakathi iipleyiti lingaphantsi kwe-66% ye-ngaphandle ubukhulu yokuqala. Ngokuba onke amabanga yaye udonga,-50%.
    • Kuba ngombhobho D / t> 10, apho kuya kubakho ukuvulwa weld phambi kokuba umgama phakathi iipleyiti yi ngaphantsi kwe-30% ye-ngaphandle ubukhulu yokuqala.
    • Kuba kwezinye ubungakanani zibhekisela ngokupheleleyo API 5L omiselweyo.

    CVN test impembelelo PSL2

    ubungakanani pipe PSL2 abaninzi kunye namabakala zifuna CVN. pipe eriyeli ukuba yavavanywa nasemzimbeni. pipe welding, ukuba yavavanywa nomzimba, ngumbhobho weld kunye zone nobushushu ezichaphazelekayo. Jonga ngokupheleleyo API 5L iinkcukacha ukuba itshati zobungakanani kunye namabakala kufuneka amaxabiso namandla ako.
