Dongosolo lathunthu loletsa mapaipi a PE.
Zida zolimbana ndi dzimbiri zoyenera kugwiritsa ntchito madzi akumwa ndi madzi otayira.
Push-fit kulumikizana kuti muchepetse kuyika.
Ikhoza kukhazikitsidwa popanda kusokoneza kupanga unsembe mofulumira komanso mosavuta.
Zosavuta kumasula.
PE restraint couplings ndi zida zomwe zimagwiritsidwa ntchito kulumikiza ndi kuletsa mapaipi a polyethylene (PE) m'makina ogawa madzi ndi gasi.Amapangidwa kuti apereke mgwirizano wotetezeka komanso wodalirika pakati pa mapaipi awiri, komanso kuteteza kusuntha kulikonse kapena kupatukana kwa mapaipi chifukwa cha mphamvu zakunja kapena kupanikizika.Kulumikizana kwa PE nthawi zambiri kumakhala ndi magawo awiri: thupi ndi mphete yoletsa.Thupi limapangidwa ndi polyethylene yapamwamba kwambiri (HDPE) ndipo imakhala ndi tsinde lomwe limakwanira kumapeto kwa chitoliro cha PE.Mphete yoletsa imapangidwa ndi chitsulo chosapanga dzimbiri ndipo imayikidwa mozungulira thupi kuti ipereke chithandizo chowonjezera ndikuletsa chitoliro kuti chisatuluke pakuyenera.Ma PE restraint couplings amagwiritsidwa ntchito popanga pansi pomwe mapaipi amatha kusuntha, kugwedezeka, kapena kuthamanga kwambiri.
Ma Ductile iron PE restraint couplings adapangidwa kuti apereke kulumikizana kodalirika komanso kotetezeka pakati pa mapaipi a polyethylene ndi zopangira chitsulo cha ductile.Zogwirizanitsazi zimapangidwa kuchokera ku zipangizo zamtengo wapatali zomwe zimagonjetsedwa ndi dzimbiri ndi kuvala, kuonetsetsa kuti zikugwira ntchito kwa nthawi yaitali komanso zolimba.Ndiosavuta kukhazikitsa ndipo safuna zida kapena zida zapadera, zomwe zimawapanga kukhala njira yotsika mtengo yogwiritsira ntchito mitundu yosiyanasiyana.Ndi mapangidwe awo apadera, ma ductile iron PE restraint couplings amapereka mgwirizano wamphamvu ndi wotetezeka womwe ungathe kupirira kuthamanga kwambiri komanso kutentha kwambiri.Ndi abwino kuti agwiritsidwe ntchito m'madzi ndi madzi otayira, mapaipi a gasi, ndi ntchito zina zamafakitale pomwe kulumikizana kodalirika ndi kotetezeka ndikofunikira.Kaya mukufunika kulumikiza mapaipi awiri azinthu zosiyanasiyana kapena kukonza payipi yowonongeka, ma ductile iron PE restraint couplings ndi chisankho chabwino kwambiri chomwe chingakupatseni zaka zambiri zantchito yodalirika.
