Iphedi yokusonga yesinyithi sisixhobo sokutywina esisetyenziswa rhoqo, esenziwe ngeentsimbi ezahlukeneyo (ezifana nentsimbi engagqwaliyo, ubhedu, i-aluminium) okanye inxeba leshiti ye-alloy. Inokuqina okuhle kunye nokumelana nobushushu obuphezulu, ukumelana noxinzelelo, ukumelana nokugqwala kunye nezinye iimpawu, ngoko ke inoluhlu olubanzi lwezicelo kwishishini leevalvu.

Iphedi yokujika yesinyithi isebenzisa ngobuchule ukumelana nobushushu, ukuqina kunye namandla esinyithi kunye nokuthamba kwezinto ezingezizo ezesinyithi, ngoko ke ukusebenza kokutywina kungcono, kwaye ukusebenza kwephedi yokujika ye-graphite yentsimbi engatyiwayo yeyona ilungileyo. Umlinganiselo woxinzelelo lwangaphambi kokucinezelwa umncinci kunowephedi yokujika ye-asbestos, kwaye akukho siphene sokuvuza kwe-capillary yefayibha ye-asbestos. Kwindawo yeoyile, i-0Cr13 isetyenziselwa imicu yesinyithi, ngelixa i-1Cr18Ni9Ti icetyiswa kwezinye izinto.

Intsimbi engatyiwayo ene-flexible graphite winding pad kwindawo yegesi, ukusetyenziswa koxinzelelo lwe-14.7MPa, kulwelo kungasetyenziswa ukuya kuthi ga kwi-30MPa. Ubushushu -190~+600℃ (xa kungekho oxygen, uxinzelelo oluphantsi lungasetyenziswa ukuya kuthi ga kwi-1000℃).

Iphedi yokujika ifanelekile kwii-heat exchangers, ii-reactors, iipayipi, iivalvu, kunye nee-pump inlet kunye nee-outlet flanges ezinoxinzelelo olukhulu kunye nokuguquguquka kobushushu. Kwiingcinezelo eziphakathi okanye eziphezulu kunye namaqondo obushushu angaphezulu kwama-300 ° C, ukusetyenziswa kweeringi zangaphakathi, zangaphandle okanye zangaphakathi kufuneka kuqwalaselwe. Ukuba kusetyenziswa i-concave kunye ne-convex flange, i-wound pad eneringi yangaphakathi ingcono.

Isiphumo esihle sokutywina sinokufunyanwa ngokuncamathisela iipleyiti zegrafiti eziguquguqukayo kumacala omabini ephedi yokujiya yegrafiti eguquguqukayo. Ibhoyila yobushushu yenkunkuma yesityalo esikhulu sesichumisi sekhemikhali sisixhobo esiphambili sobushushu obuphezulu kunye noxinzelelo oluphezulu. Iphedi yokujiya yegrafiti eguquguqukayo eneringi yangaphandle iyasetyenziswa, engavuzi xa umthwalo ugcwele, kodwa ivuza xa umthwalo uncitshisiwe. Ipleyiti yegrafiti eguquguqukayo enobukhulu obuyi-0.5mm yongezwa kumacala omabini egasket kwaye isikwe ibe yimo ye-arc. Inxalenye edibeneyo yenziwe nge-diagonal lap joint, esetyenziswa kakuhle.
