*1.WPB neWPC pombi fittings inogadzirwa kubva mumaplateti ichange iine hurefu hushoma hwe17%.
*2.Kunze kwekunge zvichidikanwa, kukosha kwekuoma hakudi kutaurwa.
Kugadzira
Iyo ASTM A234 kabhoni simbi yepombi fittings inogona kugadzirwa kubva kune isina musono pombi, welded pombi kana mahwendefa nekugadzira mashandiro ekutsikirira, kuboora, kubuda kunze, kukotama, fusion welding, machining, kana nemusanganiswa weaviri kana anopfuura maoperation aya.Ese mawelds anosanganisira ma welds mune tubular zvigadzirwa kubva kune zvinogadzirwa zvinogadzirwa zvinoenderana neASME Chikamu IX.Post-weld kupisa kurapwa pa1100 kusvika 1250 ° F [595 kusvika 675 ° C] uye radiographic kuongororwa kuchaitwa mushure mekuita welding.
