I-ASTM A234 WPB kunye nokufakwa kombhobho we-WPC kubandakanya iingqiniba, iiti, izithontsisi

ASTM A234 WPB & WPC izifakelo wombhobho kuquka ingqiniba, tee, izinciphisi Umfanekiso Featured

Inkcazelo emfutshane:

Le ngcaciso ibandakanya intsimbi yekhabhoni ekhandiweyo kunye nokufakwa kwentsimbi yealloyi yolwakhiwo olungenamthungo noludityanisiweyo.Ezi zifakelo zezokusetyenziswa kwimibhobho yoxinzelelo kunye nakwimveliso yenqanawa yoxinzelelo ukulungiselela inkonzo kumaqondo obushushu aphakathi kunye aphakamileyo.Izinto zokufakelwa ziya kubandakanya intsimbi ebuleweyo, iifogi, imivalo, iipleyiti, imveliso yetubula engenamthungo okanye edityanisiweyo edityaniswe nentsimbi yokuzalisa.Imisebenzi yokubumba okanye yokubumba inokwenziwa ngokubethelela, ukucinezela, ukugqobhoza, ukukhupha, ukuphazamisa, ukuqengqeleka, ukugoba, ukudityaniswa kweweldi, ukwenziwa komatshini, okanye ngokudityaniswa kwemibini okanye ngaphezulu yale misebenzi.Inkqubo yokuqulunqa iya kusetyenziswa kangangokuba ayiyi kuvelisa ukungafezeki okulimazayo kwizixhobo.Izinto zokufakelwa, emva kokwenziwa kwiqondo lobushushu eliphakamileyo, ziyakupholiswa kwiqondo lobushushu elingaphantsi koluhlu olubalulekileyo phantsi kweemeko ezifanelekileyo ukuthintela iziphene ezonzakalisayo ezibangelwa kukupholisa okukhawulezileyo, kodwa akukho meko ngokukhawuleza kunomlinganiselo wokupholisa emoyeni ongashukumiyo.Izifakelo ziya kuvavanywa kuxinzelelo, uvavanyo lokuqina, kunye novavanyo lwe-hydrostatic.

*2.Ngaphandle kokuba kuyafuneka, ixabiso lobulukhuni akufuneki lixelwe.

Ukwenziwa

I-ASTM A234 i-carbon steel pipe fittings inokwenziwa kwimibhobho engenamthungo, imibhobho edityanisiweyo okanye iipleyiti ngokubumba imisebenzi yokucinezela, ukubhoboza, ukukhupha, ukugoba, ukudityaniswa kwe-welding, umatshini, okanye ngokudibanisa ezimbini okanye ngaphezulu kule misebenzi.Zonke iiwelds ezibandakanya i-welds kwiimveliso ze-tubular apho ukufakelwa kwenziwa khona kuya kwenziwa ngokuhambelana ne-ASME iCandelo IX.Ukunyangwa kobushushu be-post-weld kwi-1100 ukuya kwi-1250 ° F [595 ukuya ku-675 ° C] kunye nokuhlolwa kwe-radiographic kuya kwenziwa emva kwenkqubo ye-welding.

Ngaphambili: Imibhobho yentsimbi yeCarbon engenamthungo ASTM A106 Gr.B

Okulandelayo: S355 J0 Spiral Seam Welded Umbhobho uyathengiswa
