Yintoni i-STPG 370 Pipe Material?

I-STPG 370 yinqanaba lombhobho wentsimbi ephantsi kwekhabhoni echazwe kumgangatho waseJapan JIS G 3454.

I-STPG 370 inamandla amancinci angama-370 MPa kunye namandla amancinci angama-215 MPa.

I-STPG 370 inokuveliswa njengemibhobho yensimbi engenamthungo okanye iityhubhu zetsimbi ezidityanisiweyo zisebenzisa inkqubo yokumelana nombane (ERW).Ikulungele ukusetyenziswa kwiinkqubo zemibhobho yoxinzelelo kunye namaqondo okushisa asebenzayo ukuya kuma-350 ° C.

Okulandelayo, siza kujonga kwi-STPG 370 kwiinkqubo zokuvelisa, ukubunjwa kweekhemikhali, iipropathi zemishini, iimvavanyo zoxinzelelo lwe-hydrostatic, uvavanyo olungonakalisi, kunye nokufakwa kwe-galvanized.

Inkqubo yokuVelisa

I-JIS G 3454 STPG 370 inokuveliswa ngokusebenzisa iengenamthungo or ERWinkqubo yokuvelisa, idibene neendlela ezifanelekileyo zokugqiba.

Ukongeza kumandla okuqina, amandla okuqina, kunye nobude obukhankanywe ngasentla, kukwakho uvavanyo lokuthoba kunye nokugoba.

Uvavanyo lokucaba: Xa umgama phakathi kwamacwecwe amabini ufikelela kumgama ochaziweyo H, akuyi kubakho ziphene okanye ukuqhekeka ebusweni bombhobho wensimbi.

Ukubanda: Umbhobho kufuneka ugobe i-90 ° kwi-radius yamaxesha ama-6 ububanzi bayo bangaphandle.Udonga lombhobho kufuneka lungabi naziphene okanye iintanda.

Uvavanyo lweHydrostatic okanye uvavanyo olungonakalisi

Umbhobho ngamnye wensimbi uphantsi kovavanyo lwe-hydrostatic okanye uvavanyo olungonakalisi ukujonga naziphi na iziphene ezingabonakali kwiso lenyama.

Uvavanyo lweHydrostatic

Ngokwebakala elicwangcisiweyo lobunzima bodonga lombhobho wensimbi, khetha ixabiso elifanelekileyo loxinzelelo lwamanzi, ligcine ubuncinane imizuzwana emi-5, kwaye ukhangele ukuba umbhobho wensimbi uyavuza.

I-JIS G 3454 yetafile yobunzima bombhobho wentsimbi kunye neshedyuli yePipe inokubonwa ngokucofa eli khonkco lilandelayo:

· Itshathi ye-JIS G 3454 yentsimbi yombhobho wobunzima

· ishedyuli 10,ishedyuli 20,ishedyuli 30,ishedyuli 40,ishedyuli 60, kwayeishedyuli 80.

Uvavanyo olungonakalisi

Ukuba ukuhlolwa kwe-ultrasonic kusetyenziswa, kufuneka kusekelwe kumgangatho ongqongqo kunophawu lweklasi ye-UD kwi-JIS G 0582.

Ukuba uvavanyo lwangoku lwe-eddy lusetyenzisiwe, kufuneka lusekelwe kumgangatho ongqongqo ngakumbi kunophawu lweklasi ye-EY kwi-JIS G 0583.

Iigalvanized

Kwi-JIS G 3454, iibhobho zensimbi ezingafakwanga zibizwaimibhobho emnyamakunye nemibhobho yentsimbi ebizwa ngokuba yi-galvanizedimibhobho emhlophe.

Umbhobho omhlophe: umbhobho wentsimbi

Umbhobho omnyama - umbhobho wensimbi ongeyena-galvanized

Umbhobho omnyama: umbhobho wentsimbi engekho

Inkqubo yemibhobho emhlophe kukuba imibhobho emnyama eqeqeshiweyo iyadutyulwa okanye ifakwe emanzini ukuze isuse ukungcola kumphezulu wombhobho wentsimbi kwaye emva koko ifakwe i-zinc edibana nomgangatho we-JIS H 2107 ubuncinane kwibakala 1. Eminye imiba iyenziwa. ngokuhambelana nomgangatho we-JIS H 8641.

Iimpawu zengubo ye-zinc zihlolwe ngokuhambelana neemfuno ze-JIS H 0401, iSiqendu 6.
