Feem ntau, cov kav dej txias (dawb) yog siv rau cov dej hauv tsev, dej condensed, oxygen, compressed cua, thiab lwm yam kua dej; Cov kav dej kub (txiv kab ntxwv) yog siv rau cov kav dej cua sov thiab hauv av radiant cua sov piping systems; Gas pipelines (daj) yog siv rau Natural gas, liquefied gas, gas pipelines. Kev sib txuas ntawm aluminium-yas composite yeeb nkab yog ntawm hom ferrule, yog li thawj kauj ruam hauv kev tsim kho yog kom dhau qhov kev ntsuas nruj los xyuas seb qhov kev sib txuas puas ruaj khov. Qhov thib ob yog los tiv thaiv kev co nquag thiab loosen lub ferrule. Qhov thib peb yog kom tawm hauv lub installation txaus nyob rau hauv qhov ntev kev taw qhia kom tsis txhob rub tawm. Kev txheeb xyuas ntawm PPR aluminium-yas composite yeeb nkab, zoo aluminium-yas yeeb nkab yog 5- txheej txheej wrapping, muaj txheej kub kub ntawm polyethylene thiab aluminium yeeb nkab, thiab ob txheej txheej tsis tuaj yeem tev tawm; inferior aluminium-yas yeeb nkab yog ib txheej peb txheej, txhuas thiab poly Tsis muaj kub yaj nplaum ntawm vinyls, thiab nws yog yooj yim rau tev tawm ntawm tes. Hais txog kev siv thev naus laus zis, cov kav dej zoo aluminium-yas tau ua tiav zoo, thiab cov ntawv sau rau sab nraud ntawm cov yeeb nkab yog inkjet luam tawm, thiab cov ntawv sau tau zoo ib yam li cov ntawv sau rau hauv qab ntawm lub peev xwm; tus nqi ntawm cov kav dej tsis zoo aluminium-yas feem ntau pheej yig heev, vim tias nws siv cov khoom siv zoo tib yam uas tsis yog high-density poly Vinyl cov ntaub ntawv, cov ntawv nyeem nyob rau sab nraud ntawm cov yeeb nkab, luam tawm nrog lub tshuab luam ntawv zoo tib yam, cov ntawv sau yog qhov muag plooj.
