Raws li ib qho ntawm cov yeeb nkab fittings, stainless hlau tees yog tam sim no tsim siv ob txoj kev ntws rau seamless kav ntawm Lide Pipe Industry. Ib qho yog hydraulic expansion forming, thiab lwm yam yog kub nias txoj kev. Cov txheej txheem no yog siv rau hauv cov ntawv thov uas cov kav dej muaj ceg. Vim lawv txoj kev yooj yim thiab yooj yim, stainless hlau tees tau dav siv hauv kev lag luam chemical, kev tsim vaj tsev, kev tsim khoom, kev tsim nkoj, thiab lwm yam.
1. Stainless hlau tee yeeb nkab fittings - hydraulic expansion.
Hydraulic expansion ntawm stainless hlau tee yeeb nkab fittings yog ib tug txheej txheem nyob rau hauv uas cov ceg yeeb nkab yog nthuav los ntawm cov axial nyiaj ntawm cov ntaub ntawv hlau. Nyob rau hauv cov txheej txheem no, ib tug tshwj xeeb hydraulic xovxwm txhaj cov kua rau hauv ib lub raj dawb paug nrog tib txoj kab uas hla raws li lub tee. Lub raj khoob yog ces nyem los ntawm ob kab rov tav sab cylinders ntawm hydraulic xovxwm, txo nws ntim. Raws li qhov ntim qis, lub siab ntawm cov kua hauv lub raj tsis muaj zog nce. Thaum lub siab xav tau rau kev nthuav dav ntawm tee ceg yeeb nkab mus txog, cov khoom siv hlau ntws raws cov kab noj hniav hauv pwm, ua rau cov ceg yeeb nkab nthuav.
2. Stainless hlau tee yeeb nkab fittings - kub nias.
Cov txheej txheem kub txheej txheem rau stainless hlau tee yeeb nkab fittings yuav tsum flattening ib lub raj billet, uas yog loj tshaj lub tee txoj kab uas hla, mus rau qhov xav tau loj, thiab ces tsim ib tug qhib qhov twg cov ceg yeeb nkab yuav tsim. Tom qab cua sov, lub raj xa hluav taws xob tau muab tso rau hauv cov pwm tsim, uas suav nrog cov pwm rau stretching ceg yeeb nkab. Nyob rau hauv lub siab, lub raj billet undergoes radial compression, ua rau cov hlau ntws mus rau hauv ceg yeeb nkab cheeb tsam, uas yog ces zoo li tus pwm. Tag nrho cov txheej txheem sib txuas cov radial compression ntawm lub raj billet nrog lub stretching ntawm ceg yeeb nkab. Tsis zoo li hydraulic bulging tees, qhov twg hlau them nyiaj tshwm sim axially, cov hlau nyob rau hauv lub kub pressing tee ceg yeeb nkab yog compensated los ntawm lub radial txav ntawm lub raj billet, ua nws lub npe hu ua lub radial nyiaj them txheej txheem.
