Kev sib txuas ntawm cov kav dej PE thiab cov kav hlau thiab cov khoom siv valve

Daim ntawv thov ntawm cov kav dej PE tau dhau los ua ntau dua, thiab cov neeg ua haujlwm tsim kho yuav tsum tau them nyiaj ntau rau kev sib txuas zoo ntawm PE kav dej kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm cov kav dej.
Kev sib txuas ntawm flange PE yeeb nkab thiab lwm cov yeeb nkab hlau
Cov kav hlau xws li PE cov kav dej txuas nrog flanges yog siv los txuas cov bolts ntawm flange daim hlau, uas tsis yog yooj yim rau kev khiav lag luam, tab sis kuj muaj lub sijhawm siv luv luv. Flange kev twb kev txuas yog tsuas yog siv rau kev sib txuas PE kav mus rau hlau pipelines los yog li qub, ntws ntsuas, ntsuas siab, thiab lwm yam khoom pab. Kev sib txuas flange feem ntau muaj PE txhaj tshuaj molded flanges, steel lossis aluminium flange daim, gaskets lossis sealing rings, bolts thiab ceev. Flange kev twb kev txuas yog cov txheej txheem ntawm zawm bolts thiab ceev txij thaum pib mus txog rau thaum xaus, kom lub flange sib koom nyob rau hauv kev sib cuag nrog flange tivthaiv. PE kav dej tuaj yeem txuas nrog lwm cov kav hlau.
Flange txuas txoj kev rau PE kav nrog valve fittings
Kauj Ruam 1: Raws li qhov yuav tsum tau ua ntawm flange kev twb kev txuas, weld lub txhaj molded flange kawg ntawm PE yeeb nkab uas yuav tsum tau txuas;
Kauj Ruam 2: Ntxig lwm lub flange steel rau hauv qhov kawg ntawm cov yeeb nkab hloov tau yooj yim ntawm lub valve kom txuas nrog;
Kauj Ruam 3: Raws li kev sib txuas ntawm cov yeeb nkab PE, txuas lub tiaj tus kawg (raws li cov yeeb nkab kawg) ntawm kev txhaj tshuaj flange sib koom ua ke rau PE yeeb nkab los ntawm kub melting lossis hluav taws xob melting;
Kauj Ruam 4: Muab lub flange gasket los yog lub nplhaib sib khi rau hauv cov hlau flange ntawm cov yeeb nkab hlau kawg thiab lub flange sib koom ua ke kawg lub ntsej muag (heel hom yeeb nkab kawg), kom qhov sib txuas nto yog nruj nreem;
Kauj Ruam 5: Nruab cov bolts thiab ceev lawv tusyees nyob rau hauv ib tug symmetrical txoj hauj lwm.
