Cov yeeb nkab txhawb nqa
(1) Kev txhawb nqa dav dav thiab ruaj khov yog muab rau cov yeeb nkab riser thiab kab rov tav yeeb nkab.
(2) Cov khoom txhawb nqa ruaj khov yuav tsum yog ua los ntawm cov hlau, thiab yuav tsum nyob ze ntawm cov yeeb nkab fittings thiab cov kav dej; Ib feem ntawm cov yeeb nkab tseem ceeb ntawm lub shunt ntawm cov kav dej.
(3) Cov yeeb nkab nthuav dav yuav tsum tau them nyiaj los ntawm cov yeeb nkab dabtsi yog khoov, thiab qhov ntev ntawm qhov kawg ntawm lub cantilever yuav tsum tsis txhob siab tshaj qhov ntev ntawm qhov ntsuas cov yeeb nkab.
(4) Cov yeeb nkab ncaj nraim, kev sib koom ua ke yuav tsum tau teeb tsa ntawm ob lub ntsiab lus txhawb nqa ruaj khov, thiab ua tau raws li qhov yuav tsum tau ua.
(5) Cov yeeb nkab los ntawm phab ntsa yog qhov taw qhia dav dav, nyob rau hauv lub casing los yog qhov sib txawv yuav tsum tau ntim nrog mos muab tub lim.
(6) Thaum kawg ntawm kev teeb tsa cov kav dej, cov yeeb nkab txuas yuav tsum tau siv rau kev ntsaws, thiab qhov kev ua haujlwm siab ntsaws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov kav raj xa dej.
Cov yeeb nkab rwb thaiv tsev
Cov yeeb nkab dej kub thiab txias rwb thaiv tsev, cov khoom siv yooj yim yuav tsum yog ib sab qhib siab foaming polyethylene plhaub, thickness yuav tsum tsis pub tsawg tshaj 15 hli. Tom qab cov khoom siv rwb thaiv tsev tau npog, lub ru tsev cov yeeb nkab dej txias yuav tsum tau muab qhwv nrog ob txheej rwb thaiv tsev thermal ntawm 100 ~ 120mm dav thiab 0.22mm thickness, uas yuav tsum tau ua raws li cov qauv tsim. Dub polyvinyl chloride (PVC) zaj duab xis, tiv thaiv txheej txheej txheej nrog 1 hli immersion hlau, qhov sib nrug ntawm 400 ~ 450mm.
Pipeline siab xeem
Tom qab lub raj xa dej tau teeb tsa, qhov ntsuas dej siab yuav tsum tau ua. Kev ntsuas siab yog 1.5 npaug ntawm kev ua haujlwm siab ntawm cov kav dej, tab sis tsis tsawg dua 0.60mpa. Lub siab ntawm lub kaw lus yuav tsum tau maj mam nce, thiab tom qab nce mus rau lub siab teev, lub siab yuav tsum tau stabilized rau 1h, thiab saib seb puas muaj dej to nyob rau hauv qhov kev sib cuag.
