    I-Sawh ephelele umhlahlandlela we-tube: I-A252 Ibanga le-1 lensimbi 1 Izicelo zegesi

    I-Sawh ephelele umhlahlandlela we-tube: I-A252 Ibanga le-1 lensimbi 1 Izicelo zegesi ezifakiwe Isithombe
    • I-Sawh ephelele umhlahlandlela we-tube: I-A252 Ibanga le-1 lensimbi 1 Izicelo zegesi

    Incazelo emfushane:

    I-Sawh (i-arc yelded spiral spiral) isetshenziswa kabanzi embonini kawoyela negesi ngenxa yamandla ayo aphezulu nokuqina. Kule bhulogi, sizohlola izici ezibalulekile nezinzuzo zeI-A252 IBanga le-1 lensimbi Isetshenziswa kakhulu kuzicelo ze-oyela negesi. Ekugcineni, uzoba nokuqonda okuphelele kwamapayipi we-Sawubonah nokubaluleka kwawo embonini.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    1. Qonda ipayipi le-Sawh:

    Sawh Pipesakhiqizwa kusuka emapuleti ensimbi ahlelwe ngokomoya. Amashidi akhiwa amashubhu futhi afakwe i-welded esebenzisa inqubo ye-welding engaphansi kwe-arc. Le ndlela ye-Welding iqinisekisa i-weld eqinile, eqhubekayo ngaso sonke isikhathi sepayipi, okwenza imelane kakhulu nezinto zokucindezela zangaphandle ezifana nomthelela nengcindezi. Lawa mapayipi ayaziwa ngesikhundla sawo aphatha umthwalo kanye nobuqotho bezinhlekelele, ukuzenza elungele ukuthutha uwoyela negesi.

    2. I-A252 I-PROPE 1 IPITE PIPE:

    I-A252 Ibanga 1 ukucaciswa kwepayipi lensimbi ehlelekile lenzelwe izinhlelo zokusebenza zokucindezela. Lawa mapayipi akhiqizwa ngensimbi ye-A252, enezakhiwo ezinhle kakhulu zemishini kanye namandla aphezulu ashubile. I-A252 I-Grade 1 Ipayipi lensimbi isetshenziselwa kakhulu amandla ayo okubekezelela izingcindezi eziphakeme futhi amelane nokugqwala kanye noguquko ezindaweni ezinokhahlo kawoyela kanye negesi.

    3. Izinzuzo zepayipi lensimbi 1 lensimbi 1:

    a) amandla nokuqina:I-A252 IBanga le-1 lensimbiIqinile futhi ihlala isikhathi eside, ingamelana nemithwalo esindayo futhi ilungele amasistimu wokuhambisa uwoyela kanye negesi. Amandla abo aphezulu aphezulu aqinisekisa ukuqina isikhathi eside futhi anciphise izidingo zokulungiswa.

    b) Ukumelana nokugqwala: Amapayipi kawoyela negesi athambekele ekugqwaneni ngenxa yezici ezinzima zemvelo. I-A252 I-STREP PIPE IPROCE ifaka umhlanga ongezelelekile wokugqwala, onjenge-epoxy ethambile (FBE), ukuthuthukisa ukuqina kwawo futhi kwandise impilo yayo yenkonzo.

    c) Ukuvumelana nezimo: Amapayipi we-Sawh angenziwa kuma-diameter ahlukahlukene nobude ukuze ahlangabezane nezidingo ezithile zephrojekthi. Lokhu kuguquguquka kusiza ukufaka ngaphandle kwesidingo samalunga amaningi, ukunciphisa ubungozi bokuvuza.

    d) Imali ebizayo: A252 Ibanga 1 Ipayipi lensimbi linikeza isixazululo esisebenza ngempumelelo yamapayipi kawoyela namagesi. Impilo yabo ende yenkonzo kanye nezidingo zokulungiswa okuphansi zinciphisa izindleko zokusebenza ngokuhamba kwesikhathi.

    a. Indlela ye-deoxidation iqokwa kanjena:

    I-FF: Insimbi ebulewe ngokuphelele equkethe izinto ezibophayo ze-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isib

    b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

    4. Ukusetshenziswa kwepayipi lensimbi 1 lensimbi 1:

    I-A252 Ibanga 1 Ipayipi lensimbi linezinhlobonhlobo zezicelo embonini kawoyela negesi, kufaka phakathi:

    a) Amapayipi okuhambisa: asetshenziselwa ukuthutha uwoyela ongahluziwe, igesi yemvelo neminye imikhiqizo ye-petroleum evela emikhakheni yokukhiqiza ukuze asebenze ezindaweni zokuhlaziya nezikhungo zokuhambisa.

    b) Ukushayela okusogwini okusogwini Ukumelana kwabo nokugqwala namakhono aphezulu wokucindezela kubenza balungele ukuhlola okujulile kolwandle.

    c) Ukucolisiswa: Amapayipi e-A252 e-A252 e-A252 asetshenziswa kabanzi ekuhlaziyweni kwezokuthutha uwoyela ongahluziwe kanye nemikhiqizo kaphethiloli.

    Ipayipi le-SSAW

    Ekuphetheni:

    I-Sawh Pipes, ikakhulukazi amapayipi e-A252 e-A252 e-A252, adlala indima ebalulekile ku-Ipayipi likawoyela negesiimboni. Amandla abo, ukuqina, nokumelana nokugqwala kwenza ukuba kube ukukhetha okuthembekile kwezicelo ezahlukahlukene. Ukuqonda izinzuzo zamapayipi we-sawh kanye nezimpawu zabo ezithile kungasiza ekuqinisekiseni ukuthuthwa okuphumelelayo kwamafutha negesi ngenkathi kunciphisa izindleko zokulungiswa kanye nokwanda kwephrojekthi ukusebenza kahle.
