A216 WCB pob valve yog ib qho kev lag luam valve feem ntau tsim los ntawm ASTM A216 WCB carbon steel khoom. Nws ua tiav qhov nruab nrab kaw-tawm thiab khiav txoj cai los ntawm 90℃kev sib hloov ntawm lub pob. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv kev sib xyaw ua ke ntawm lub siab - lub zog valve lub cev (nrog lub siab tsis kam ntawm Ntau dua lossis sib npaug ntawm 450 MPa) thiab ntau yam kev sib khi tsim, ua rau nws haum rau qhov kub ntau (-40℃rau +550 degree) thiab kev ntsuas siab (PN1.6 txog PN42 MPa).
Piv rau li qub ua los ntawm lwm cov ntaub ntawv, carbon steel pob li qub muaj tus nqi siab dua -kev ua tau zoo ntawm kev tswj tsis tau - cov xov xwm corrosive heev (xws li dej, chav dej, thiab cov khoom siv roj). Lawv tau siv dav hauv kev lag luam xws li petrochemicals, lub zog hluav taws xob, thiab kev tsim vaj tsev hauv nroog.
