DN600 ductile iron Manhole Cover

The spheroidalchivharo chegomba imhando ye spheroidal graphite cast iron. Iyo spheroidal graphite cast spheroidal graphite ine spheroidal uye inoculated kuti ibudirire kuvandudza michina yesimbi yakakandwa, kunyanya iyo plastiki uye kuoma, nekudaro kuwana yakakwirira simba kupfuura iyo kabhoni simbi. Ductile iron imhando yemhando yepamusoro-yakasimba yakakandwa simbi yakagadzirwa muma1950s. Kubata kwayo kwakazara kuri pedyo neyesimbi. Iyo yakavakirwa pakuita kwayo kwakanaka uye yakashandiswa zvakabudirira kukanda mamwe masimba akaomarara, simba, kuomarara uye kupfeka kuramba. Zvikamu zvine zvinodiwa zvepamusoro. Ductile simbi yakakurumidza kugadzirwa kuita simbi yakakandwa inoshandiswa zvakanyanya mushure megrey cast iron. Iyo inonzi "iron-based steel" inonyanya kureva ductile iron.

Application
(1) Pombi yemagetsi emagetsi zvakanaka; Post, telecommunication, pombi yekukurukurirana zvakanaka;
(2) Mwenje wemugwagwa zvakanaka, kudzora moto zvakanaka, marudzi ese evharuvhu zvakanaka;
(3) Mvura yemuguta, pombi inofambisa mvura mutsime; Kupisa kunopihwa, gasi tsime;
(4) Anti-corrosion project, mugero wakazaruka; Izvo pamwe chete zvinogona kuitwa maererano nezvinodiwa nevatengi.

1. Kurwisana nekubiwa - Composite Manhole Kavha ine shockproof rabha sealing haisi-metal, isinga-conductive uye isiri-sparking, haina kukosha kwekugadzirisa zvakare, kugadzirisa zvachose matambudziko ekuba.

2. High load capacity -Iyo huru inoumba fiberglass uye unsaturated resin. oad inokwana A15, B125, C250, D400, E600.

3. Yemahara dhizaini-Senge Ruvara, Logo, Panel, Mutoro uye Dimension inogona kugadzirwa maererano nezvinodiwa nemutengi.

4. Upenyu hurefu -Upenyu hudiki makore makumi matatu pasina kuchengetedzwa.

5. Yakanyatsovharwa -Inogona kuiswa hermetically, uye zvinobudirira kudzivirira magasi ane chepfu kubuda kubva mucesspool. uye hapana kusvibiswa kweruzha kana kudzoka.

6. Kupfeka kwakanaka uye kusaita ngura —Haife yakaita ngura nekuti ine kusakara kwakanaka uye kusaita ngura.

7. Kuramba tembiricha yepamusoro uye yakaderera — Yakanakisa insulator (kubva-40°C ~200°C)

8. Huremu huremu uye mutengo unokwikwidza— huremu hwechivharo chemugodhi wakaumbwa kunyanya SMC chivharo chemugodhi wakareruka. Iyo composite manhole chivharo chiri nyore kutakura, kuisa uye kugadzirisa.
