Ductile Iron Pipe inorema zvakadii​

Mukugadzira mainjiniya emvura nedhiraivha, network dzemapaipi emakanzuru, uye masisitimu emapaipi emaindasitiri,ductile simbi pombirave chinhu chakakodzera kutsiva mapaipi esimbi nesimbi echinyakare nekuda kwehunhu hwayo hwakanaka hwemakanika uye kuramba kwayo ngura. Kunzwisisa hunyanzvi hwemapaipi esimbi akagadzirwa kwakakosha kune vagadziri, vatengi, uye makambani ekuvaka, kungave kwenzvimbo dzemvura kana dzekutakura tsvina. Chinyorwa chino chichatoraDINSEN ductile simbi pombisemuenzaniso wekutsanangura zvakarongeka marongero ayo, huremu, kumanikidzwa kwekushanda, uye hunhu hwekuputira.

I. Magadzirirwo eDuctile Iron Pipe uye Zviyero: Ungaziva Sei Modeli?

Pakusarudza mapaipi, zvakakosha kutanga wajekesa saizi nehukuru hwemapaipi esimbi ane ductile. Mitemo yepasi rose inonyanya kuenderana neISO 2531 kana EN 545, yakarongwa nedhayamita (DN).

Tichitora DINSEN ductile iron pipe semuenzaniso, mapaipi eK9 grade (standard wall thickness level) anowanzo shandiswa, ane dhayamita dzinotangira paDN80 kusvika kuDN2000. Heano mamwe mapombi ane saizi dzakajairika:

• DN80: Dhayamita yekunze 98mm, ukobvu hwemadziro 6.0mm
• DN100: Dhayamita yekunze 118mm, ukobvu hwemadziro 6.0mm
• DN200: Dhayamita yekunze 222mm, ukobvu hwemadziro 6.3mm
• DN400: Dhayamita yekunze 429mm, ukobvu hwemadziro 8.1mm
• DN1000: Dhayamita yekunze 1048mm, ukobvu hwemadziro 13.5mm

Magiredhi akasiyana eukobvu hwemadziro (K8, K9, K10, K12) anokanganisa kugona kwekutakura kumanikidzwa uye huremu hweyuniti yepombi.Vashandisi vanogona kusarudza zvakakodzera zvichienderana nekumanikidzwa kwedhizaini.

II. Kurema pamita imwe neimwe yepombi yesimbi ine ductile: Pombi yesimbi ine ductile inorema zvakadii?

Mubvunzo unowanzo bvunzwa mukutenga mainjiniya ndewekuti: Pombi yesimbi inorema zvakadii? Huremu hwepombi yesimbi inorema hunosanganisira huremu hwepombi uye huremu hwesoketi, zvichikanganisa zvakananga kutakurwa, kukwidzwa, uye mari yekuisa.

Tichitora DINSEN K9 grade ductile iron pipe (yakajairwa kureba mamita matanhatu) semuenzaniso, huremu hwedzidziso ndehwekuti:

• DN100: Inenge 15.1 kg/m → 95 kg papombi imwe neimwe
• DN200: Inenge 30.6 kg/m → 194 kg papombi imwe neimwe
• DN300: Inenge 50.8 kg/m → 323 kg papombi imwe neimwe
• DN500: Inenge 104.3 kg/m → 669 kg papombi imwe neimwe
• DN800: Inenge 215.2 kg/m → 1394 kg papombi imwe neimwe

Huremu chaihwo hunogona kusiyana zvishoma nekuda kwezvinhu zvakaita sehukobvu hwezinc coating uye inner cement mortar lining. DINSEN inogona kupa mapepa ekuverenga huremu akarurama ekugadzirisa bhajeti reprojekiti uye kuronga mafambiro ebasa.

III. Kumanikidzwa Kushanda kweDuctile Iron Pipe

Pombi yesimbi ine simba guru rekudhonza uye simba rekudzvanya rinotenderera. Pombi yesimbi ine simba reK9 grade inowanzova nekumanikidzwa kwekushanda kwe16 bar (1.6 MPa), nepo ukobvu hwemadziro hwakakwira (senge K12) hwakakodzera kushandiswa kwekumanikidzwa kwe25 bar kana kunyange 40 bar.

Mapaipi esimbi eDINSEN anogadzirwa zvinoenderana neISO 2531. Pombi yega yega inoedzwa ne hydrostatic isati yabuda mufekitori kuti ive nechokwadi chekuti yakachengeteka yakakwira ka1.5 kupfuura simba rekushanda, zvichiita kuti ive yakakodzera kutapurirana mvura kure, mapaipi anokwira pombi, uye mapaipi eindasitiri ane simba repamusoro.

IV. Zinc Coating yekudzivirira ngura

Basa reZinc Coating paDuctile Iron Pombi Chimwe chezvinhu zvakakosha zvekudzivirira mapaipi akavigwa ndeye zinc coating pamapaipi esimbi akavigwa. Zinc coating haingope chete dziviriro ye cathodic asiwo inogadzira system inodzivirira ngura ine pendi yekunze kana polyethylene sheathing.

Mapaipi esimbi eDINSEN ane ductile anouya akajairwa aine zinc coating ye ≥200 g/m² (zvichienderana neISO 8179 standard), yakafukidzwa ne red epoxy asphalt kana polyurethane finishing layer, zvichivandudza zvakanyanya kuramba ngura uye hupenyu hwese. Kune ivhu rinoparadza kana nzvimbo dzinodzivirira zvakanyanya, zinc coating yekuwedzera + PE film kana full polyurethane coating inowanikwa, ine hupenyu hwebasa hwakagadzirirwa hwemakore 50-100.

V. Sei Uchifanira Kusarudza Mapaipi Esimbi eDINSEN Ductile?

Semutengesi wemapaipi esimbi ane ductile, DINSEN inopa mhando dzakasiyana dzemagadzirirwo kubva kuDN80 kusvika kuDN2000, inotsigira ukobvu hwakasiyana hwemadziro akadai seK8, K9, K10, uye K12, uye inogona kugadzirisa hurefu, machira emukati (simende mortar/epoxy resin), uye mhinduro dzekudzivirira ngura dzekunze kuti dzienderane nezvinodiwa nevatengi.

Mapaipi ese esimbi ane chitupa cheISO 2531 / EN 545. Matafura akazara ehuremu, saizi, kumanikidzwa kwekushanda, uye parameter ye zinc coating anowanikwa. Kurongedza kunze kwenyika uye masevhisi ekutakura zvinhu anotsigirwa.

Kuti uwane rumwe ruzivo rwakadzama nezvehukuru hwemapaipi esimbi ane ductile uye saizi uye matafura ekusarudza kana maturusi ekuverenga huremu, ndapota shanyirai peji reDINSENkana kuti bata timu yekutengesa yehunyanzvi zvakananga.
