PE restraint couplings yog fittings siv los txuas thiab tswj cov kav dej polyethylene (PE) hauv cov dej thiab cov pa xa hluav taws xob.Lawv yog tsim los muab kev ruaj ntseg thiab txhim khu kev qha kev sib txuas ntawm ob lub kav dej, thaum tseem tiv thaiv kev txav los yog sib cais ntawm cov kav dej vim yog sab nraud quab yuam lossis siab.PE restraint couplings feem ntau muaj ob ntu: lub cev thiab lub nplhaib tuav.Lub cev yog ua los ntawm high-density polyethylene (HDPE) thiab muaj lub qhov (socket) kawg uas haum rau qhov kawg ntawm cov yeeb nkab PE.Lub nplhaib tuav yog ua los ntawm cov hlau tsis muaj steel thiab muab tso rau ib ncig ntawm lub cev los muab kev txhawb nqa ntxiv thiab tiv thaiv cov yeeb nkab los ntawm kev rub tawm ntawm qhov haum.PE restraint couplings feem ntau yog siv nyob rau hauv underground daim ntaub ntawv uas cov kav dej yuav raug rau hauv av txav, seismic kev ua si, los yog siab.
Ductile hlau PE restraint couplings yog tsim los muab ib tug txhim khu kev qha thiab ruaj ntseg kev twb kev txuas ntawm polyethylene kav thiab ductile hlau fittings.Cov couplings no yog tsim los ntawm cov khoom siv zoo uas tiv taus corrosion thiab hnav, ua kom muaj kev ua haujlwm ntev thiab ua haujlwm ntev.Lawv yooj yim rau nruab thiab yuav tsum tsis muaj cov cuab yeej tshwj xeeb lossis cov cuab yeej siv, ua rau lawv muaj txiaj ntsig zoo rau kev siv ntau yam.Nrog lawv cov qauv tsim tshwj xeeb, cov hlau nplaum PE tiv thaiv couplings muab kev sib txuas ruaj khov thiab ruaj ntseg uas tuaj yeem tiv taus siab thiab kub heev.Lawv yog cov zoo tagnrho rau siv nyob rau hauv cov dej thiab cov dej khib nyiab, cov kav dej, thiab lwm yam kev siv hauv kev lag luam uas muaj kev sib txuas ruaj khov thiab ruaj ntseg yog qhov tseem ceeb.Txawm hais tias koj xav tau txuas ob lub kav dej ntawm cov khoom sib txawv lossis kho cov kav dej puas, cov kav hlau PE tiv thaiv kev sib txuas yog qhov kev xaiv zoo tshaj plaws uas yuav muab kev pabcuam ntau xyoo.
