Basa reBhuronzi Rakawandainoshandiswa kubatanidza nzira dzemvura nedzokudzosera mvura pamwe nemidziyo yekuunganidza mvura yemapaipi akasiyana-siyana ekupisa. Zvinoenderana nemvura inopinda neinobuda, imhando yemanifold uye muunganidzi wemvura, saka inonzi manifold kana kuti manifold muinjiniya, kana kuti manifold muchidimbu. Basa rayo: Kuchinja-chinja uye kuenzana ndezve, manifold inowanzo kamurwa kuita copper manifold uye stainless steel manifold, saka manifold iri nani here kusarudza stainless steel kana copper? Ndeupi musiyano uripo pakati pezvinhu zviviri izvi?

Musiyano uripo pakati pe copper manifold ne stainless steel manifold:

Chekutanga: kana ngura nekuoxidation zvakasiyana

Simbi isina ngura haizooxidize uye haizooxidize. Simbi chaiyo ye304 isingaoxidize haifanire kuchinja ruvara kwemakore mazhinji. Kana ruvara rukachinja, zvinoreva "simbi isina ngura". Mhangura ichaoxidizezwa kuti igadzire verdigris. Mazhinji emhando dzebrass anozokura mumwedzi mishoma. Yaiva yakasviba uye yakaoxidizezwa.

Chechipiri: saizi yemutariri yakasiyana

Dhayamita huru yesimbi isingasvibiswi inosvika DN40; dhayamita huru yesimbi yebrass inowanzova DN25, 32.

Chechitatu: Nguva yewarandi yakasiyana

Nguva yewarandi yemhando ye304 stainless steel manifold chaiyo yakareba kupfuura yebrass. Kunyangwe zvisingataurwi kuti manifold esimbi isina tsvina anogara kwenguva refu, nguva yewarandi yemhando yebrass manifolds iri pamusika makore 2-3, nepo manifold esimbi isina tsvina achishandiswa. Nguva yewarandi inosvika makore mashanu.

China: mitengo yakasiyana yezvinhu

Brass isimbi isina ferrous, inodhura kupfuura simbi isina ngura, asi mutengo wesimbi isina ngura unodhura zvakanyanya mushure mekugadzirwa kwayo. Ichi ndicho chikonzero nei kune vagadziri vazhinji ve "black heart" vanoshandisa "stainless iron" kuita se "stainless iron", izvo zvinoita kuti vanhu vanzwe sekuti mhando yesimbi dzisina ngura haina kunaka, zvichikanganisa mukurumbira wavo.

Zvisinei, pamusika uripo iye zvino, kusanganisira kuEurope, mutengo wemhando dzesimbi dzisina ngura unodhura kupfuura wemhando dzesimbi dzisina ngura, uye "simbi isina ngura" ne "simbi isina ngura" hazvisi nyore kusiyanisa. Varidzi vazhinji nevanopa mabasa vachiri kusarudza mhando dzesimbi dzisina ngura.
