Ductile Iron Wide Tolerance Stepped Coupling

Ib tug ductile hlau dav kam rau siab stepped coupling yog ib hom kev sib txuas siv los txuas ob lub kav dej lossis fittings ntawm ntau qhov sib txawv.Nws yog ua los ntawm cov hlau ductile, uas yog hom cam khwb cia hlau uas hloov tau yooj yim thiab ruaj khov dua li cov cam khwb cia hlau.

Kev tsim qauv dav dav ntawm kev sib txuas tso cai rau ntau qhov ntau ntawm cov yeeb nkab sib txuas, txo qhov kev xav tau ntawm ntau qhov sib txuas thiab fittings.Cov txheej txheem tsim ntawm lub coupling muab kev ruaj ntseg thiab nruj haum nruab nrab ntawm cov kav dej, kom ntseeg tau tias tsis muaj kev sib txuas.

Ductile hlau dav kam rau ua kauj ruam txuas txuas yog feem ntau siv hauv cov dej thiab cov dej khib nyiab kho, nrog rau kev siv hauv kev lag luam xws li roj thiab cov kav dej.Lawv kuj tau siv hauv cov kav dej thiab HVAC los txuas cov kav dej sib txawv.

Zuag qhia tag nrho, ductile hlau dav kam rau ua kauj ruam couplings yog ib qho kev txhim khu kev qha thiab nqi-zoo rau kev sib txuas cov kav dej ntawm ntau qhov sib txawv, muab kev ruaj ntseg thiab tsis muaj kev sib txuas uas tuaj yeem tiv taus qhov xav tau ntawm ntau yam kev siv.

• Dav sab nraud txoj kab uas hla: qhov nruab nrab ntawm 21 hli ntawm ib sab.

• Cov qauv me me rau qhov Nominal Diameter.

• Kev ntseeg tau:

-Txoj kev sib txuas ruaj khov thaum compressing lub gasket

nruab nrab ntawm qhov kawg-flange thiab lub tes tsho mus rau hauv cov yeeb nkab nto.

- Anticorrosion tiv thaiv: epoxy hmoov txheej (150 μm) thiab

Dacromet® 500 Gr.B rau bolts.

• Yooj yim thiab ceev ntawm installation:

- Angular deflection ± 6 °.

- absorbs expansion thiab contraction.

- Ua kom muaj kev tsis sib haum xeeb.

- Qhov tseem ceeb qhov sib txawv.

• Ua raws li cov qauv:

- NF A 48-830: Foundry khoom - Spheroïdal graphite cam khwb cia hlau

fittings rau PVC haus cov kav dej hauv qab siab.

- NF EN 545: Cov kav dej hlau, fittings, accessories thiab lawv cov pob qij txha rau

cov kav dej - qhov yuav tsum tau ua thiab cov txheej txheem xeem.

TS EN ISO 2531 Cov kav dej hlau, fittings, accessories thiab lawv cov pob qij txha rau

kev siv dej.

• Pom zoo:

- Cov dej haus pom zoo.

• Nco tseg:

Qhov kev sib txuas no tsis tuaj yeem tiv taus lub zog longitudinal thiab paub tseeb

Kev tswj kom txaus yog muab los tiv thaiv cov kav dej dislocation.
