Mu gutunganya imiti cyane—nk'imirongo y'amazi ya catalyst, ibice bya coking byatinze, na reactors za polyethylene (HDPE) polymerization—intebe zoroshye za polymeric cyangwa elastomeric ni ikibazo gikomeye. Ibyuma bisanzwe nka PTFE, RPTFE, cyangwa ndetse na PEEK yashimangiwe bihita bitsindwa n'imbaraga zangiza z'amacatalyst, isuri ry'imashini, no guhindagurika k'ubushyuhe bukabije. Iyo ibintu byoroshye byangiritse, ingaruka zihita zibaho: gupfunyika kw'amazi, gufunga umurongo, no gufunga utunguranye kw'ibimera.
Kugira ngo habeho igihe cyo gukora imashini no kwigunga burundu mu bihe bikomeye, abahanga mu by’imikorere n’abahanga mu by’ubwirinzi barimo kwitandukanya n’ibikoresho bisanzwe. Igisubizo kiri mu by’ikoranabuhanga ryakozwe neza cyane.valve z'umupira zicaye mu cyuma.

1. Supersonic Metallurgy: Ubukanishi bwa HVOF bwo gusiga imvange z'umupira zicaye mu byuma
Ishingiro ry'icyizere cya serivisi ikomeyevalve z'umupira zicaye mu cyumabigenwa n'ubusugire bw'imigozi n'ubukomere bw'ubuso bw'imyambaro yayo yo mu maso. Aho kwishingikiriza ku buryo gakondo bwo gushushanya,IKORANABUHANGA RYA NSW VALVEibikoreshoOgisijeni yihuta cyane (HVOF)Gutera ubushyuhe. Ubu buryo bukoresha ibyuma bya karubide bigezweho ku bikoresho bifite aloyi nyinshi, harimo ASTM A351 CF8M, CF3M, na Super Duplex stainless steels.
Mu gihe cy’uburyo bwacu bwo gukora HVOF, icyo kintu gikomeye cyinjizwa mu muyoboro w’umuriro uterwa imbaraga na ogisijeni na peteroli yo mu rwego rwo hejuru.
