* 1. WPB thiab WPC cov yeeb nkab fittings tsim los ntawm cov phiaj yuav tsum muaj tsawg kawg ntawm 17%.
* 2. Ntshe yuav tsum muaj, lub hardness tus nqi tsis tas yuav tshaj tawm.
Tsim
Lub ASTM A234 carbon steel cov yeeb nkab fittings tej zaum yuav ua los ntawm cov kav dej seamless lossis daim phiaj, kev sib xyaw, lossis los ntawm kev sib xyaw ntawm ob lossis ntau dua cov haujlwm no. Txhua cov welds suav nrog Welds hauv tubular cov khoom lag luam los ntawm cov fittings uas tau ua raws li ASME Seem IX. Tom qab kev kho cua sov thaum 1100 txog 1250 ° F [595 rau 675 ° C] thiab tshuaj ntsuam C] thiab tshuaj ntsuam yuav tsum tau ua tom qab cov txheej txheem vuam.
