Thaum Lub Peb Hlis 2026, Lub Tebchaws Yelemees tau tshaj tawm cov qauv txheej txheem txheej txheem tshiab rau cov kav hlau yeeb nkab fittings, E DIN EN 15189: 2026-03. Cov qauv no yog tsim tshwj xeeb rau cov txheej txheem polyurethane sab nraud ntawm cov kav hlau hlau, fittings, thiab accessories. Nws yuav siv sij hawm tam sim ntawd raws li kev tshaj tawm thiab yuav ua lub luag haujlwm tseem ceeb rau kev tsim khoom thiab kev ntsuam xyuas cov txheej txheem rau cov hlau yeeb nkab fittings nyob rau hauv cov teb chaws Europe, tsav lub standardization thiab upgrading ntawm cov khoom zoo nyob rau hauv lub cheeb tsam.
Nws tau tshaj tawm tias cov txheej txheem polyurethane yog qhov tseem ceeb tiv thaiv kev tiv thaiv corrosion ntawm cov hlau yeeb nkab fittings, thiab lawv qhov kev ua tau zoo ncaj qha txiav txim siab txog kev pab cuam lub neej ntawm cov fittings nyob rau hauv ib puag ncig nyuaj xws li cov dej hauv nroog thiab cov kav dej thiab cov kav dej phwj tuaj. Cov txheej txheem tshiab tau tshaj tawm qhia meej txog cov txheej txheem kev cai thiab kev sim cov txheej txheem rau txheej txheej, tsom rau kev tswj cov ntsiab lus tseem ceeb xws li txheej thickness, adhesion, thiab corrosion kuj. Nws kuj tseem txhim kho cov txheej txheem kev sim los ntawm kev siv cov qauv tsim nyog los xyuas kom meej qhov traceability thiab controllability ntawm txheej txheej zoo, zoo tiv thaiv tsis xws luag xws li npuas, tawg, thiab xau.
Tshaj tawm ua lus Askiv thiab German, 46-nplooj tus qauv siv rau sab nrauv polyurethane coatings rau txhua hom kev lag luam hauv nroog thiab kev lag luam ductile hlau yeeb nkab fittings, npog cov khoom siv nrog ntau hom kev sib txuas xws li lub qhov (socket) thiab flange txuas. Kev ua raws li tus qauv tshiab no yuav ntxiv dag zog rau kev tiv thaiv corrosion thiab kev nyab xeeb ntawm cov hlau yeeb nkab fittings hauv lub teb chaws Yelemees thiab thoob plaws Tebchaws Europe, txuas ntxiv lub neej kev pab cuam ntawm cov fittings, thiab txo cov nqi tu rau hauv nroog thiab cov kav dej sib txuas.
Tsis tas li ntawd, tus qauv tshiab imposes stricter ua raws cai nyob rau hauv lub ntiaj teb no manufacturers ntawm ductile hlau yeeb fittings exporting rau cov teb chaws Europe. Cov tuam txhab lag luam yuav tsum ua kom zoo dua cov txheej txheem tsim khoom thiab ua kom zoo dua cov txheej txheem kuaj xyuas kom ntseeg tau tias cov khoom txheej txheej txheem ua tau raws li tus qauv yuav tsum tau ua ua ntej nkag mus rau European lag luam. Cov kws tshaj lij kev lag luam tau sau tseg tias qhov kev hloov kho tshiab no ua raws li lub ntiaj teb sib txawv mus rau ib puag ncig tus phooj ywg thiab ruaj khov hlau yeeb nkab fittings. Nws yuav tsis tsuas yog tsav kev hloov kho thev naus laus zis hauv European yeeb nkab haum kev lag luam tab sis kuj tseem ua haujlwm tseem ceeb rau kev ua kom zoo dua thoob ntiaj teb cov qauv rau cov yeeb nkab haum txheej.
