Izinyathelo Zokuqaphela Ukuthenga I-Diameter Enkulu Eqondile Eqondile

Ngaphambi kokuthenga amapayipi ensimbi omthungo (LSAW) anobubanzi obukhulu obukhulu, kufanele ulandele imininingwane eklanywe ngaphambili, ubude, izinto zokwakha, ubukhulu bodonga, izindinganiso zokushisela kanye nezidingo zokushisela, okufanele kukhulunywe ngazo ngaphambi kokuthenga.

1. Eyokuqala yincazelo.Isibonelo, u-800mm ubizwa nangokuthi i-DN800, okuhlanganisa u-820mm no-813mm wochungechunge lwe-A no-B, noma ububanzi obungaphandle obungu-800mm kufanele budingeke ngokucacile ukuze kugwenywe ukulahlekelwa okungadingekile.

2. Ubukhulu bodonga lwepayipi lensimbi lomthungo oqondile wobubanzi obukhulu budingeka bube ngu-16mm.Kungenzeka ukuthi ubukhulu bangempela bezinto zokusetshenziswa buzoba ngu-15.75mm no-16.2mm, futhi kuzoba nomehluko ongaphezulu noma ophansi.Lokhu ukuchezuka okuvamile.Ngenxa yokuthi amapayipi ensimbi othungayo aqondile wonke amanani ethani, kuyadingeka ukuxhumana kusengaphambili ukuze kugwenywe umehluko wesisindo.

3. Ubude obujwayelekile bepayipi lensimbi lomthungo oqondile wobubanzi obungu-12m.Uma idinga ukulungiswa, idinga ukwaziswa kusengaphambili, ngoba intengo yobude obunqunyiwe izobiza kakhulu.Uma kungathintwanga kusenesikhathi, izoba ngu-9.87m ubude, futhi umenzi ngokuvamile unikeza u-9.9m ngokuqondile.

4. Izinto zokuthenga amapayipi ensimbi omthungo oqondile wobubanzi obukhulu kufanele kwaziswe kahle, futhi izinto ezisetshenziswayo akufanele kube yi-OEM.Ngaphezu kwalokho, izinto zokwakha kufanele ziqinisekiswe, futhi uhlu lwezinto ezibonakalayo zomshini wensimbi kufanele lunikezwe.Noma yiziphi izinkinga ezibonakalayo zizobuyiswa futhi zinxeshezelwe.

5. Izinga lokushisela lokukhiqiza nokucubungula kufanele lihambisane nokushisela okuzenzakalelayo kwe-arc okuzenzakalelayo kwe-LSAW GB/T3091-2015, futhi isitifiketi sekhwalithi yomkhiqizo siyadingeka.Uma izinga lingahlangabezani nezidingo, umkhiqizo uyehluleka.

6. Uma uthenga amapayipi ensimbi othungelwano oluqondile anobubanzi obukhulu, kuyadingeka ukuthi kuxhunyanwe kusenesikhathi mayelana nezinga lokutholwa kwamaphutha e-weld, ngoba ukutholwa kwamaphutha e-weld kuzobiza imali eyengeziwe.inkathazo.

7. Ngaphezu kwalokho, amapayipi ensimbi anobubanzi obukhulu obuqondile ngaphezu kuka-1020mm angase akhiqize amashisela amabili.Amaphrojekthi amaningi ngeke amukele ama-welds amabili ngaphandle kokuxhumana kwangaphambili, futhi azobizwa ngokuthi amapayipi ensimbi anesici.

Ngakho-ke, kuyadingeka ukuxhumana kahle kusengaphambili ngaphambi kokuthenga noma iyiphi ipayipi yensimbi, okubangela izingxabano ezingadingekile nokulahlekelwa kwezomnotho.
