Lub npe tag nrho ntawm cov yeeb nkab ua ntej insulated yog: high-density polyethylene txheej tiv thaiv yeeb nkab, nruj polyurethane ua npuas ncauj yas prefabricated ncaj qha faus rwb thaiv tsev yeeb nkab.
Nws yog cov kav dej sib xyaw nrog peb hauv ib lub qauv uas muaj cov raj tiv thaiv sab nraud, txheej rwb thaiv tsev, thiab cov tub ntxhais tub ntxhais sib txuas ua ke.
Seamless steel kav feem ntau yog siv rau cov kav hlau me dua DN200, thiab cov qauv ua tiav yog GB / T 8163; Cov kav hlau uas muaj txoj kab uas hla ntau dua los yog sib npaug rau DN200 feem ntau yog ua los ntawm cov kav hlau welded kauv steel kav. Cov qauv kev ua tiav yog GB / T9711 thiab cov kav dej steel APL SPEC 5L.
Cov yeeb nkab tiv thaiv sab nrauv yog cov yeeb nkab uas muaj polyethylene txheej txheej, txheej txheej rwb thaiv tsev yog ib qho tawv polyurethane ua npuas ncauj, thiab cov yeeb nkab tseem ceeb yog cov yeeb nkab steel.
Lub raj tiv thaiv sab nrauv yog tsim thiab tsim siv cov khoom siv polyethylene hauv ib qho extruder. Tom qab xeb tshem tawm kev kho mob rau seamless los yog kauv kav, lub rwb thaiv tsev txheej kev them nyiaj yug yog tsau, thiab txheej tiv thaiv lub raj yog sheathed rau cov yeeb nkab steel siv lub tshuab threading. Txav mus rau lub foaming platform dua, tag nrho fuse polyether thiab isocyanate siv lub tshuab foaming, thiab ceev nrooj xam tus nqi ntawm cov npuas dej uas tuaj yeem txhaj rau hauv qhov sib txawv ntawm cov yeeb nkab steel thiab cov raj tiv thaiv sab nraud. Cia nws sawv ntsug rau kaum feeb, luam tawm thiab tshuaj tsuag lub ntim, thiab tom qab ntawd txav mus rau qhov chaw tos 10 teev ua ntej tawm hauv lub hoobkas.
Pre insulated piping muaj cov yam ntxwv zoo xws li lub teeb ntho, rwb thaiv tsev, tsis muaj zog, tsis nqus dej, thiab yooj yim siv. Lawv tau dhau los ua cov ntaub ntawv tseem ceeb rau kev rwb thaiv tsev, dej tsis zoo, kev sib khi, thiab kev sib khi hauv kev lag luam xws li kev tsim kho, kev thauj mus los, roj av, tshuaj lom neeg, lub zog, thiab tub yees.
Thaum khaws cov kav dej polyurethane, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
1. Tsis txhob tiv tauj nrog lwm cov khib nyiab lossis tshuaj lom neeg kom tsis txhob muaj kev puas tsuaj lossis kev kis kab mob.
2. Thaum khaws cia, cov kav dej polyurethane yuav tsum muab tso rau hauv kab rov tav lossis ntsug, thiab kev txhawb nqa yuav tsum muaj zog kom tsis txhob deformation lossis puas.
