Iphedi yokusonga yensimbi iyinto yokuvala evame ukusetshenziswa, eyenziwe ngezinsimbi ezahlukene (njengensimbi engagqwali, ithusi, i-aluminium) noma i-alloy sheet wound. Inokuqina okuhle kanye nokumelana nokushisa okuphezulu, ukumelana nengcindezi, ukumelana nokugqwala nezinye izici, ngakho-ke inezinhlelo zokusebenza eziningi embonini yamavalvu.

Iphedi yokugoqa yensimbi isebenzisa ngobuhlakani ukumelana nokushisa, ukuqina kanye namandla ensimbi kanye nobumnene bezinto ezingezona ezensimbi, ngakho-ke ukusebenza kokuvala kungcono, futhi ukusebenza kwephedi yokugoqa ye-graphite yensimbi engagqwali kuhambisana netheyiphu eguquguqukayo kungcono kakhulu. Isilinganiso sokucindezela ngaphambi kokucindezela sincane kunesephedi yokugoqa ye-asbestos, futhi akukho sici sokuvuza kwe-capillary ye-asbestos fiber. Endaweni yamafutha, i-0Cr13 isetshenziselwa imichilo yensimbi, kuyilapho i-1Cr18Ni9Ti inconywa kwezinye izinto.

Insimbi engagqwali enephedi yokugoqa ye-graphite eguquguqukayo endaweni yegesi, ukusetshenziswa komfutho ongu-14.7MPa, kuketshezi kungasetshenziswa kufika ku-30MPa. Izinga lokushisa -190~+600℃ (uma kungekho umoya-mpilo, umfutho ophansi ungasetshenziswa kufika ku-1000℃).

Iphedi yokugoqa ifanelekela ama-heat exchanger, ama-reactor, amapayipi, ama-valve, kanye nama-flange okungena nokuphuma ephampu anokucindezela okukhulu kanye nokushintshashintsha kwezinga lokushisa. Uma kunengcindezi ephakathi noma ephezulu kanye namazinga okushisa angaphezu kuka-300 ° C, kufanele kucatshangelwe ukusebenzisa izindandatho zangaphakathi, zangaphandle noma zangaphakathi. Uma kusetshenziswa i-flange egobile kanye ne-convex, iphedi yokulimaza enendandatho yangaphakathi ingcono.

Umphumela omuhle wokuvala ungatholakala nangokunamathelisa amapuleti e-graphite aguquguqukayo kuzo zombili izinhlangothi zephedi yokugoqa ye-graphite eguquguqukayo. Ibhoyila yokushisa engcolile yesitshalo esikhulu somanyolo wamakhemikhali iyithuluzi elibalulekile lokushisa okuphezulu kanye nokucindezela okuphezulu. Iphedi yokugoqa ye-graphite eguquguqukayo enendandatho yangaphandle iyasetshenziswa, engavuzi lapho umthwalo ugcwele, kodwa ivuza lapho umthwalo uncishisiwe. Ipuleti le-graphite eliguquguqukayo elingu-0.5mm ubukhulu liyangezwa kuzo zombili izinhlangothi ze-gasket bese lisikwa libe yisimo se-arc. Ingxenye ehlangene yenziwe nge-diagonal lap joint, esetshenziswa kahle.
