Gupfunyika ibyuma ni ibikoresho bisanzwe bifunga kashe, bikozwe mubyuma bitandukanye (nk'ibyuma bidafite ingese, umuringa, aluminium) cyangwa igikomere cy'urupapuro. Ifite elastique nziza nubushyuhe bwo hejuru, kurwanya umuvuduko, kurwanya ruswa nibindi biranga, bityo ikaba ifite uburyo bwinshi bwo gukoresha mubikorwa bya valve.

Icyuma gihinduranya icyuma gikoresha ubuhanga bwo kurwanya ubushyuhe, kwihangana n'imbaraga z'icyuma no koroshya ibikoresho bitari ubutare, bityo imikorere yo gufunga ni nziza, kandi imikorere yicyuma kitagira umuyonga kizunguruka cyoroshye cya grafite nicyiza. Ikigereranyo cya precompression ni gito ugereranije na asibesitosi ihindagurika, kandi nta nenge ya asibesitosi fibre capillary yamenetse. Muburyo bwa peteroli, 0Cr13 ikoreshwa kumurongo wibyuma, mugihe 1Cr18Ni9Ti irasabwa kubindi bitangazamakuru.

Ibyuma bitagira umuyonga hamwe na grafite ya grafite ihindagurika mu buryo bwa gaze, gukoresha umuvuduko wa 14.7MPa, mumazi urashobora gukoreshwa kugeza 30MPa. Ubushyuhe -190 ~ + 600 ℃ (mugihe habuze ogisijeni, umuvuduko muke urashobora gukoreshwa 1000 ℃).

Ikizunguruka gikwiranye no guhanahana ubushyuhe, reakteri, imiyoboro, indangagaciro, hamwe na pompe yinjira hamwe n’ibisohoka hamwe n’umuvuduko mwinshi n’imihindagurikire y’ubushyuhe. Ku muvuduko wo hagati cyangwa muremure n'ubushyuhe burenga 300 ° C, hagomba gutekerezwa gukoresha impeta y'imbere, hanze cyangwa imbere. Niba flange ya convex na convex ikoreshwa, igikomere gikomeretsa nimpeta y'imbere nibyiza.

Ingaruka nziza yo gufunga irashobora kandi kuboneka mugushiraho plaque ya grafite ihindagurika kumpande zombi za fagitire ya grafite. Amashanyarazi yimyanda yinganda nini yifumbire mvaruganda nibikoresho byingenzi byubushyuhe bwinshi numuvuduko mwinshi. Imiterere ihindagurika ya grafite ihindagurika hamwe nimpeta yo hanze irakoreshwa, idatemba iyo umutwaro wuzuye, ariko ugatemba iyo umutwaro ugabanutse. Isahani yoroheje ya plaque 0.5mm yongewe kumpande zombi za gaze hanyuma igabanywa muburyo bwa arc. Igice gihuriweho gikozwe muri diagonal lap gufatanya, ikoreshwa neza.
