PPR yeeb nkab fittings feem ntau tsis tawg thaum qhov kub thiab txias, tab sis thaum PPR yeeb nkab thiab cov yeeb nkab fittings yog welded, vuam flanging tig daj thiab vuam tsis txhim khu kev qha; Qhov tshwm sim no tuaj yeem raug ntaus nqi rau "virtual welding" tshwm sim los ntawm cov vuam kub ntau dhau. Qhov kub ntawm qhov vuam nyob deb tshaj 270 degrees thiab qhov kub siab ua rau cov qauv molecular ntawm cov khoom, uas ua rau kev laus thiab discoloration ntawm PPR yeeb nkab khoom.
Yog li ntawd, welding thiab installation yuav tsum tau ua raws li nruj me ntsis raws li kev tsim kho specifications. Qhov zoo tshaj plaws vuam kub rau kub-melt socket ntawm PPR yeeb fittings yog 260 ntxiv rau 10 degree. Txawm li cas los xij, yog tias qhov ntsuas kub tsawg dhau, lub raj ppr yog qhov ua rau tawg, yog li xyuam xim rau qhov kub thiab txias thaum siv pp raj.
