MalungaUfakelo lwemibhobho ye-ASTM A234 WPB
I-ASTM A234 yiNgcaciso yoMgangatho wokufakelwa kombhobho wentsimbi kubandakanya i-carbon kunye ne-alloy steel material yeenkonzo ezimodareyitha neziphezulu zobushushu.Igubungela izixhobo zentsimbi zeentlobo ezingenamthungo kunye ne-welded.Izixhobo zombhobho wentsimbi zisetyenziswa kwiipayipi zoxinzelelo kunye noxinzelelo lweenqanawa.Ezi zixhobo zokufakelwa ziquka intsimbi ebuleweyo, i-forgings, imivalo, iipleyiti, i-seamless okanye i-HFW (i-fusion welded) iimveliso zemibhobho, kunye nentsimbi yokuzalisa yongezwe.
Yintoni iWPB?
W = EWELDABLE / eyenziweyo
P = INXULUMENE NEnombolo ye-P YEMALI YE-ALLOY
B = BHEKISELELA KUBUNCINCI OBUBONAKALAYO LWEMPHATHISWA
Zifumaneka kuhlaziyo lwamva nje lwe-ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, kunye ne-MSS-SP-97.Ikwasetyenziswa ngokubanzi kwimibhobho yoxinzelelo kunye nakwimveliso yenqanawa yoxinzelelo kwinkonzo kumaqondo obushushu aphakathi kunye aphakamileyo.Amabanga ngala ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 kunye neWP22.
Iinkcukacha:

Umahluko phakathi kwe-A105 kunye ne-A234
I-ASTM A234 WPB Izixhobo zoMbhobho zenziwe ngentsimbi yekhabhoni ekhandiweyo yomelele kakhulu kwaye ingasetyenziswa kwiimfuno zamandla aphezulu.I-ASTM A234 WPB iphathwa ubushushu kwaye emva koko ivunyelwe ukuba iphole ngokukhawuleza.
Izixhobo zeCarbon Steel Forged Fittings zizifakelo zombhobho ezenziwe nge-A105 Material.Ezi ziveliswa kwi-annealed, normalized, normalized and tempered or quenched and tempered.
