1. Tus neeg teb xov tooj ntawm PE yeeb nkab vuam tshuab yuav tsum tau cob qhia tshwj xeeb los ntawm lub tuam tsev muaj feem cuam tshuam thiab dhau qhov kev ntsuam xyuas ua ntej ua tus ncej. Kev siv los ntawm cov neeg tsis yog neeg ua haujlwm raug txwv nruj heev.
2. Cov khoom siv hluav taws xob thiab kev tswj hwm ntawm PE yeeb nkab vuam tshuab tsis muaj dej tsis muaj dej, thiab dej yuav tsum tsis txhob tso cai rau cov khoom siv hluav taws xob thiab tswj qhov chaw ntawm PE yeeb nkab vuam tshuab thaum ua haujlwm thiab siv. Nyob rau hauv rooj plaub ntawm kev tsim kho hauv huab cua los nag, kev tiv thaiv yuav tsum tau ua rau cov hluav taws xob thiab tswj qhov chaw ntawm PE yeeb nkab vuam tshuab.
3. Thaum PE yeeb nkab vuam tshuab yog vuam hauv qab xoom, kev tiv thaiv tsim nyog yuav tsum tau ua kom ntseeg tau tias qhov vuam nto muaj qhov kub txaus.
4. Tag nrho cov khoom nyob rau hauv kev sib cuag nrog vuam nto yuav tsum huv si. Vuam nto yuav tsum huv si thiab qhuav ua ntej welding. Cov khoom uas yuav tsum tau welded yuav tsum tsis txhob muaj kev puas tsuaj, impurities, los yog av (xws li av, roj, chips, thiab lwm yam).
5. Txhawm rau kom muaj kev txuas ntxiv ntawm cov txheej txheem vuam, cov cua txias txaus yuav tsum tau ua tom qab vuam tiav kom tshem tawm nws cov kev ntxhov siab sab hauv.
6. Rau piping Cheebtsam nrog dn≤63mm los yog phab ntsa thickness e< 6mm,="" nws="" tsis="" pub="" siv="" kub-melt="" taub="" qab="">
7. Thaum cov yeeb nkab cov khoom sib txawv ntawm SDR series yog welded rau ib leeg, nws raug nquahu kom siv electrofusion kev sib txuas los yog siv cov txheej txheem tsim nyog los ua kom cov pob qij txha welded muaj tib lub phab ntsa tuab.
8. Thaum siv PE yeeb nkab vuam tshuab rau vuam, txhua qhov vuam yuav tsum muaj cov ntaub ntawv ntxaws ntxaws. Tus thawj vuam cov ntaub ntawv yuav tsum tsawg kawg muaj xws li huab cua puag, ambient kub, welder code, weld tooj, yeeb yam specification hom, vuam siab, thiab luag siab, Pressurization lub sij hawm, cua sov phaj kub, hloov lub sij hawm, tshav kub nqus lub sij hawm, txias lub sij hawm, thiab lwm yam.
9. Nws yog nruj me ntsis txwv tsis pub nce lossis txo cov fuse hauv lub fuse ntawm PE yeeb nkab vuam tshuab.
10. Thaum siv, kev ua haujlwm ntawm PE yeeb nkab vuam tshuab yuav tsum raug soj ntsuam txhua lub sijhawm. Yog tias muaj suab nrov txawv txav lossis kub dhau, nws yuav tsum tau nres tam sim ntawd.
11. Lub PE yeeb nkab vuam tshuab yuav tsum tau ua kom huv si txhua lub sijhawm kom tsis txhob muaj plua plav thiab kev ua haujlwm tsis zoo.
