Cov ntaub ntawv pov thawj kev ua raws cai
Ua ntej thov thib peb -cov ntaub ntawv xeem rau cov ntaub ntawv xws li 304 stainless hlau. Xyuas kom tseeb tias cov ntsiab lus ntawm cov ntsiab lus tseem ceeb{{3}xws li chromium thiab npib tsib xee- ua tau raws li cov qauv hauv tebchaws (xws li GB/T 3280) kom tsis txhob muaj cov khoom tsis zoo thiab tiv thaiv cov teeb meem yav tom ntej xws li pitting corrosion lossis to.
Sealing thiab Dimensional raug kuaj xyuas
Xyuas kom meej tias cov EPDM los yog silicone gaskets muaj ib tug hardness nyob rau hauv lub 60-70 Shore A ntau yam thiab hais tias lub coupling lub puab txoj kab uas hla kam rau ua ib tug sib tw ntawm cov yeeb nkab txoj kab uas hla; qhov no tau lees tias yuav xau- ua haujlwm dawb txawm tias nyob hauv dej rauj.
Kev tsim nyog thiab daim ntawv thov tsim nyog
Rau cov phiaj xwm tiv thaiv hluav taws, paub meej tias cov khoom muaj ntawv pov thawj raws li GB 5135.11 tus qauv. Rau cov ntawv thov zaub mov thiab dej haus, xaiv cov khoom huv huv - qib sealing Cheebtsam; rau corrosive chemical ib puag ncig, ua ntej corrosion-cov ntaub ntawv tiv taus xws li 316L stainless hlau.
Kev xaiv tus neeg muag khoom
Ua ntej cov neeg muag khoom muaj peev xwm muab ntau yam sib txuam fittings kom tsis txhob muaj kev sib khi txaus ntshai los ntawm kev tsis sib haum xeeb nyob rau hauv cov khoom sib txawv. Tsis tas li ntawd, txaus siab rau cov neeg muag khoom uas muab cov khoom ua ntej -fabrication thiab kev xa khoom hauv zos los pab txo cov sijhawm tsim kho.
Tshaj tawm -Delivery Spot Checks
Thaum tau txais, pom pom cov yeeb nkab kawg thiab cov npoo sab hauv ntawm cov couplings kom ntseeg tau tias lawv tsis muaj burrs. Ua qhov chaw kuaj xyuas ntawm tus qauv me me los txheeb xyuas qhov ua tau zoo ntawm hydrostatic siab thiab paub meej tias cov khoom specifications ua raws li cov qauv tsim.
