Mumapurojekiti ekupa mvura nekubvisa mvura mumakanzuru, mapaipi esimbi akagadzirwa nesimbi anoshamisa haakurudzirwi, zvichiita kuti mvura ifambe zvakanaka mumaguta. Zvisinei, kana watarisana nesarudzo dzakasiyana-siyana, ungasarudza sei chaiyo? Usazvidya moyo, muverengi anodiwa! Jindalai Steel Group Co., Ltd. ichakupa ruzivo rwakakwana rwemhando dzakasiyana dzemapaipi esimbi akagadzirwa nesimbi, kubva kuK9 kusvika kuK7, zvese zvaunoda.
Kutanga, ngatikurukurei mubvunzo uyu wagara uripo: K9 kana K7? Kana uchida mapaipi anokwanisa kutsungirira kumanikidzwa kwemvura yemuguta, K9 ndiyo sarudzo yakakodzera. Yakafanana negamba pakati pemapaipi esimbi ane ductile, inobata zviri nyore nharaunda dzine kumanikidzwa kwakanyanya (≥1.6MPa). K7, kune rumwe rutivi, yakafanana nemubatsiri wayo anokwanisa, yakakodzera zviri nani pakushandisa mvura ine zvinodiwa zvishoma zvekumanikidzwa. Saka, kana uchida kuti mapaipi ako emvura esimbi ashande zvakanaka, saka K9 ndiyo sarudzo yakanakisisa!
Zvino, ngatitaurei nezvezvinhu. Kuchengetedzeka ndiko kwakakosha kana zvasvika pamapombi emvura yekunwa. Ungave uchishamisika kuti ndeipi yakachengeteka, QT450-10 kana QT500-7. QT500-7 yakafanana ne "muchengeti wekuchengetedza" wenyika yemapaipi esimbi ane ductile—yakasimba, inogara kwenguva refu, uye sarudzo yakachengeteka yemvura yako yekunwa. Saka, kana uchida kuti mvura yako ive yakachena semvura yechitubu chemakomo, sarudza QT500-7.
Saka zvakadini nemapaipi egasi rechisikigo? Unofanira kusarudza mapaipi esimbi ane ductile kana mapaipi esimbi here? Mhinduro ndeiyi: mapaipi esimbi ane ductile akafanana neshamwari yakavimbika, anogara achisvika nenguva. Akasimba uye anogara kwenguva refu, anokwanisa kutsungirira kumanikidzwa. Mapaipi esimbi, kune rumwe rutivi, akareruka uye ari nyore kutakura, zvichiita kuti ave sarudzo yakanaka mune mamwe mashandisirwo. Zvinoenderana nezvaunoda chaizvo, asi ese ari maviri ane zvakanakira zvawo. Yeuka, mumamiriro ezvinhu akaoma, mapaipi esimbi ane ductile ndiyo sarudzo yakavimbika!
Zvino, ngatitaurei nezvekuisa. Kana zvasvika pamapombi akavigwa, ungashamisika kuti ndeipi iri nyore: mapaipi esimbi emhando yesocket-type ductile kana mapaipi esimbi emhando yeflanged ductile. Mapaipi emhando yesocket akafanana neshamwari iri nyore kushandisa, yakakodzera chero nzvimbo, uye iri nyore kuisa. Mapaipi emhando yeflange akaoma zvishoma, asi kubatana kwacho kwakachengeteka uye kunogona kumira kumanikidzwa kwakanyanya. Saka, kana zviri nyore kwauri, mapaipi emhando yesocket ndiyo sarudzo yako yakanakisa!
Saka, ungasarudza sei pakati pemadhayamita madiki ane matambudziko (≤100mm) uye dhayamita hombe (≥Mapaipi esimbi ane ductile ye 800mm? Zvavanosarudza zvinonetsa. Kune mapaipi ane dhayamita diki, unofanirwa kutarisa padanho rekuyerera kwemvura uye zvinodiwa pakumanikidzwa. Kune mapaipi ane dhayamita hombe, unofanirwa kufunga nezvenzvimbo yekuisa uye mukana wekuti ngura iitike.
Kana zvasvika pakuora, kana uri kubata nemapombi emvura ine acid nealkali, ungangove wakatyoka pakati pekushandisa mapaipi esimbi akajairwa kana mapaipi ane anti-corrosion coating (akadai se epoxy coal tar kana polyurethane). Mhinduro yacho iri nyore: sarudza mapaipi ane coated! Akafanana neraincoat yemvura inonaya kana paine dutu.—zviri nani kuchengetedzeka pane kuti uzvidembe!
Muchidimbu, kungave uchida mapaipi esimbi e centrifugal ductile iron kana kuti uri kufunga nezvemutengesi wemapaipi esimbi e ductile wekusarudza, yeuka kuti Jindalai Steel Group ndiyo inotsigira nguva dzose. Neruzivo rwakakodzera uye kusetsa, unogona kufamba munyika yemapaipi esimbi e ductile zviri nyore senyanzvi. Saka ngatisimudzei magamba asina kurumbidzwa anobatsira chinyararire mukuvaka zvivakwa zvedu.—Mapaipi esimbi ane ductile! Makorokoto!
