Product Description
Cement Lined Ductile Iron Pipes C25 C30 txais cov khoom siv hlau ua cov khoom siv hauv paus. Ib txheej cement-mortar tiv thaiv yog siv rau sab hauv phab ntsa ntawm centrifugal txau. Nws yog cov txheej txheem siv ntau tshaj plaws rau kev siv dej hauv nroog thiab kev txuag dej, feem ntau yog siv rau kev siv dej thiab kev xa dej.
Class-C siab-rated ductile hlau kav yog tsim nyob rau hauv nruj raws li thoob ntiaj teb cov qauv ISO 2531 thiab EN 545, tsim tshwj xeeb rau haus-dej kis tau tus mob systems. Muaj ob chav kawm siab muaj xws li:
C25: Tso cai ua haujlwm siab 25 bar (2.5 MPa)
C30: Tso cai ua haujlwm siab 30 bar (3.0 MPa)
Rau cov kav dej ntawm tib lub nominal txoj kab uas hla (DN), C25 thiab C30 sib koom zoo tib yam sab nraud diameters, sib txawv tsuas yog nyob rau hauv phab ntsa tuab kom tau raws li qhov yuav tsum tau ua nyob rau hauv ntau yam kev ua haujlwm. Tus qauv nteg ntev yog 6 m, nrog 5.7 m txiav-rau-ntev xaiv muaj. Sab hauv cement-mortar hauv ob sab phlu raws li cov qauv thickness specifications: 4 hli rau DN Tsawg dua los yog sib npaug rau 600 hli thiab 5 hli rau DN Ntau tshaj los yog sib npaug rau 700 hli. Sulphate-resistant cement hauv ob sab phlu tuaj yeem kho raws li cov dej xav tau.

Nta
Cement-mortar lined ductile hlau kav (Class C25, C30) feature zoo heev ductility los tiv thaiv hauv av thiab lwm yam loads, nrog rau lub neej kev pab ntawm 50-100 xyoo.
Cement-mortar hauv ob sab phlu tiv thaiv cov yeeb nkab sab hauv, tiv thaiv cov dej liab thiab nplai tsim.
Optimized phab ntsa-thickness tsim rau cov kav dej C-class muab cov nqi zoo dua piv nrog cov kav dej K-class.
Txheej txheem installation
Excavate lub trench thiab tshem tawm cov av xoob thiab pob zeb. Muab graded granular txaj los ua ib qho ruaj khov, theem puag.
Tshawb xyuas cov kav dej thiab fittings rau kev puas tsuaj rau cov cement-mortar hauv ob sab phlu thiab txheej txheej sab nraud. Txheeb xyuas nominal txoj kab uas hla, chav kawm siab (C25 / C30) thiab cov qauv tsim nyog.
Nqa cov kav dej nrog cov hlua muag kom tsis txhob muaj txheej txheej puas. Txo cov kav dej mus rau hauv trench thiab align pipeline centerline thiab elevation.
Ntxuav tswb thiab spigot xaus kom huv si kom tshem tawm cov xuab zeb thiab khib nyiab. Haum EPDM roj hmab gasket rau hauv lub tswb zawj. Siv cov roj nplua nyeem pom zoo rau ntawm lub qhov ncauj thiab qhov chaw gasket.
Teem cov yeeb nkab axes. Siv cov tuaj-nrog rau thawb spigot tag nrho rau hauv tswb mus rau cov kab kos cim. Xyuas kom lub gasket tsis twisted los yog dov. Txhim kho pob zeb thrust blocks ntawm khoov, tees thiab tuag-kawg los tiv thaiv hydraulic thrust.
Saib xyuas qhov sib koom ua ke kom paub meej tias lub rooj zaum gasket kom raug.
Sau thiab compact haunch cheeb tsam ntawm ob sab ntawm cov yeeb nkab ua ntej. Ua cov txheej txheem backfill thiab compaction saum cov yeeb nkab yas. Zam cov pob zeb nyuaj ntaus lub cev yeeb nkab.
Ua qhov ntsuas hydrostatic tom qab rov ua dua. Tuav lub siab ntsuas thiab xyuas seb puas muaj qhov xau.
Tshem tawm thiab tua kab mob ua ntej ua haujlwm.
