Ductile Iron Wide Tolerance Anadutsa Kulumikizana

Cholumikizira chachitsulo cholumikizira cholumikizira ndi mtundu wa zolumikizira zomwe zimagwiritsidwa ntchito kulumikiza mapaipi awiri kapena zolumikizira zamitundu yosiyanasiyana.Amapangidwa ndi chitsulo cha ductile, chomwe ndi mtundu wa chitsulo chosungunuka chomwe chimasinthasintha komanso cholimba kuposa chitsulo chachikhalidwe.

Kulekerera kwakukulu kwa kugwirizanitsa kumapangitsa kuti pakhale kukula kwakukulu kwa mapaipi kuti agwirizane, kuchepetsa kufunikira kwa ma couplings angapo ndi zopangira.Mapangidwe apamwamba a kugwirizana amapereka chitetezo chokhazikika komanso cholimba pakati pa mapaipi, kuonetsetsa kuti palibe kutayikira.

Ma Ductile iron wide tolerance stepped couplings amagwiritsidwa ntchito kwambiri m'malo oyeretsera madzi onyansa, komanso m'mafakitale monga mapaipi amafuta ndi gasi.Amagwiritsidwanso ntchito popanga mapaipi ndi ma HVAC kulumikiza mapaipi amitundu yosiyanasiyana.

Ponseponse, ma ductile iron wide tolerance stepped couplings ndi njira yodalirika komanso yotsika mtengo yolumikizira mapaipi amitundu yosiyanasiyana, kupereka kulumikizana kotetezeka komanso kopanda kutayikira komwe kumatha kupirira zofuna zamitundu yosiyanasiyana.

• Kutalikirana kwa kunja: pafupifupi 21 mm mbali imodzi.

• Chiwerengero chochepa cha zitsanzo za Nominal Diameter.

• Kudalirika:

- Kutayikira kokhazikika komwe kumalumikizana ndikukakamiza gasket

pakati pa mapeto a flange ndi manja pa chitoliro pamwamba.

- Chitetezo cha anticorrosion: zokutira ufa wa epoxy (150 μm) ndi

Dacromet® 500 Gr.B ya mabawuti.

• Kusavuta komanso kuthamanga kwa kukhazikitsa:

- Kupatuka kwa angular ± 6 °.

- Imayamwa kukulitsa ndi kutsika.

- Imalekerera kusanja bwino.

- Kusiyana kofunikira kokhazikika.

• Kugwirizana ndi miyezo:

- NF A 48-830: Zinthu zoyambira - Spheroïdal graphite cast iron

zopangira PVC madzi akumwa mapaipi pansi pampanipani.

TS EN 545: Mapaipi achitsulo a Ductile, zopangira, zowonjezera ndi zolumikizira zawo

mapaipi amadzi - zofunikira ndi njira zoyesera.

TS EN ISO 2531 mapaipi achitsulo, zopangira, zowonjezera ndi zolumikizira zawo

ntchito madzi.

• Chivomerezo:

- Madzi akumwa ovomerezeka.

• Dziwani:

Kulumikizana uku sikutsutsana ndi mphamvu zautali ndipo onetsetsani

kuletsa kokwanira kumaperekedwa kuti mapaipi asasunthike.

Deta yaukadaulo

• Mtundu: DN 40/50 mpaka 400.

• Kupanikizika kwakukulu pantchito: PN 16.

• Kutentha: +0°C mpaka +60°C.

• Torque: 60 mpaka 70 Nm.

Mapulogalamu

• Ma network a madzi akumwa.

• Kupopa, mankhwala, kusunga madzi.

• Maukonde oteteza moto.

• Njira zothirira.

• Njira zotayira zimbudzi ndi ngalande za madzi amvula

(Mtundu wa WC - EN 681-1).

Mayesero

• Mayeso osindikiza molingana ndi muyezo wa ISO 2531.
