I-spiral yenxeba
I-gasket yenxeba yenxeba yeyona ixhaphazi exhaphakileyo esetyenziswa kwizityalo zemveliso. I-gasket ekhethiweyo kwaye ifakwe i-stiral ye-spirals inokumelana namaqondo obushushu aphezulu kunye noxinzelelo, ukuthintela ukuvuza kuyo yonke i-Lifepan.
Ngenxa yolwakhiwo lwayo olukhethekileyo lomoya kunye neempawu zefilitha, i-gasket yenxeba enesiphene inokubonelela ngefuthe lokutywina elithembekileyo phantsi koxinzelelo olwahlukileyo kunye neemeko zobushushu. Kwi-pipeline uqhagamshelo lweshishini le-petrochemical, inokuthintela ngokuphumeza ioyile, igesi kunye nezinye izinto zakudala.
I-spiral aunds isetyenziswa ngokubanzi kwimibhobho kwi-Petrochemical, oomatshini, umbane, i-metallgergy, i-metimergerger, i-Medight, amayeza, amandla e-Atos, amasebe e-Atospace kunye namasebe e-Atospace. Ingakumbi izihlandlo apho kufuneka ikwazi ukumelana nobushushu obuphezulu, uxinzelelo oluphezulu okanye imithombo yeendaba, i-spitives yenxeba idlale ukusebenza kakuhle.

Ungayikhetha njani i-stict yenxeba
Iimpawu eziphakathi:Ngokweepropathi zendlela ephakathi kumbhobho, njengokungakhathali, ubuthi, njl njl. Umzekelo, kwimithombo yeendaba ezonakeleyo kakhulu, i-corrosion-enganyangekiyo intsimbi yentsimbi kunye nentsimbi yentsimbi kunye ne-polytetrafluoroothyleners kufuneka zikhethwe.
Uxinzelelo lokusebenza kunye nobushushu:Ngokutsho koxinzelelo lokusebenza kunye noluhlu lobushushu lwenkqubo ye-pipelil, khetha i-gasket yenxeba enesiphene esinokumelana neemeko ezihambelanayo. Kwiqondo lobushushu obuphezulu kunye neemeko eziphezulu zoxinzelelo, kufuneka ukukhetha i-gasket ngamandla aphezulu, izixhobo zobushushu obunganyangekiyo kunye nemilo yolwakhiwo.
Uhlobo lweFlanger kunye nobukhulu:Ubungakanani kunye nobume be-gasket ye-spiral yenxeba kufuneka bahambelane nohlobo kunye nobungakanani beflonge ukuqinisekisa ukuqina nokutywina kofakelo.
