    Tsananguro pfupi:

    Chikamu chino cheEuropean Standard chinotsanangura mamiriro ekugadzirwa kwezvinhu zvekuvaka zvakagadzirwa nesimbi dzakasungirirwa, dzine maburi edenderedzwa, sikweya kana rectangular uye chinoshanda kuzvikamu zvekuvaka zvisina maburi zvakagadzirwa nesimbi dzinotonhora pasina kurapwa kwekupisa kunotevera.

    Cangzhou Spiral Steel Pipes Group Co., Ltd inopa mapaipi esimbi ane denderedzwa ane gomba.


    Ruzivo rweChigadzirwa

    Matagi eChigadzirwa

    Nhanganyaya:

    Munzanga yemazuva ano, kutakurwa kwezvinwiwa nemagasi zvinobudirira kwakakosha kumaindasitiri akawanda. Chimwe chezvinhu zvakakosha pakuona kuti mashandiro emagetsi ako afamba zvakanaka.sisitimu yepombiiri kusarudza mapaipi akakodzera. Pakati pesarudzo dzakasiyana-siyana dziripo, S235 JR Spiral Steel Pipe isarudzo yakavimbika nekuda kwehunhu hwayo hwepamusoro. Blog rino rine chinangwa chekuongorora zvakanakira kushandisa mapaipi esimbi eS235 JR spiral mumasisitimu emapaipi, richitarisa chimiro chayo che spiral welded.

    a. Nzira yekubvisa oxidation inotsanangurwa seinotevera:

    FF: Simbi yakafa zvizere ine zvinhu zvinosunga nitrogen muhuwandu hwakakwana kuti isunge nitrogen iripo (semuenzaniso 0,020% yeAl yose kana 0,015% yeAl inonyungudika).

    b. Kukosha kwakanyanya kwenitrogen hakushandi kana makemikari ari muchikamu ichi achiratidza huwandu hweAl hushoma hwe0,020% nechiyero cheAl/N che2:1, kana kana paine zvimwe zvinhu zveN-binding zvakakwana. Zvinhu zveN-binding zvinofanira kunyorwa muGwaro reKuongorora.

    Kuedzwa kweHydrostatic

    Kureba kwepaipi imwe neimwe kunofanira kuyedzwa nemugadziri kusvika pakumanikidzwa kwemvura kuchaita kuti pamadziro epaipi pave nekumanikidzwa kusingasviki 60% yesimba remubereko rakatarwa patembiricha yemumba. Kumanikidzwa kunofanira kutsanangurwa nemuenzaniso unotevera:
    P=2St/D

    Kusiyana Kunobvumidzwa Muhuremu neMakuriro

    Kureba kwepombi imwe neimwe kunofanira kuyerwa zvakasiyana uye huremu hwayo hahufanirwe kusiyana ne10% pamusoro kana 5.5% pasi pehuremu hwayo hwepfungwa, zvichiverengerwa uchishandisa hurefu hwayo nehuremu hwayo pahurefu hweyuniti imwe neimwe.
    Dhayamita yekunze haifanirwe kusiyana kupfuura ±1% kubva padhayamita yekunze yakatarwa.
    Ukobvu hwemadziro chero nguva hahufanirwe kupfuura 12.5% ​​pasi peukobvu hwemadziro hwakatarwa

    Pipe yeHelical Welded

    1. Nzwisisa pombi yesimbi inotenderera yeS235 JR:

    S235 JR spiral steel pombiipombi yakasungirirwa inotenderera inoshandiswa zvakanyanya mumasisitimu emapaipi. Yakagadzirwa nesimbi yepamusoro-soro zvichienderana nezvinodiwa pasi rose, zvichiita kuti igare kwenguva refu uye irambe yakasimba. Maitiro ekugadzira anosanganisira kuumbwa kwesimbi inotenderera inotenderera, iyo inozosungirirwa kusvika pakureba kwainodiwa. Iyi nzira yekuvaka inopa mapaipi mabhenefiti akakosha kupfuura mapaipi echinyakare ane musono wakatwasuka.

    2. Mabhenefiti ekuvaka pombi dzakasungirirwa nesimbi:

    Kuvakwa kweS235 JR Spiral Steel Pipe ne spiral weld kunopa mabhenefiti akawanda kuma pombi systems. Chekutanga, continuous spiral weld seams inowedzera kusimba kwechimiro che pombi, zvichiita kuti irambe yakasimba mukumanikidzwa kwemukati nekunze. Chimiro ichi chinoitawo kuti mutoro ugovaniswe zvakaenzana, zvichideredza njodzi yekukundikana kwe pombi. Pamusoro pezvo, chimiro che spiral che pombi chinobvisa kudiwa kwekusimbisa mukati, nokudaro zvichivandudza kugona kwekuyerera kwemvura uye kuderedza kurasikirwa kwekumanikidzwa panguva yekufambisa mvura. Nzvimbo isina musono inoenderera mberi ye pombi ye spiral inoderedza njodzi yekubuda kwemvura uye inovandudza kuchengetedzeka nekushanda zvakanaka kwe pombi system.

    3. Wedzera kugara kwenguva refu uye kushanduka-shanduka:

    Mapaipi esimbi eS235 JR Spiral Steel akasimba zvakanyanya nekuda kwezvinhu zvayo zvekuvaka zvemhando yepamusoro. Anodzivirira ngura, kukweshwa uye mamiriro ekunze akaipisisa, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana zvinosanganisira kutakurwa kwemafuta negesi, masisitimu emvura uye mapurojekiti ezvivakwa. Kuchinja-chinja kwemapaipi aya kunoita kuti agadziriswe zviri nyore kuti asvike pazvinodiwa zvepurojekiti. Pamusoro pezvo, ari nyore kuisa nekugadzirisa, zvichiwedzera kukwezva kwawo uye zvichibatsira kuti pave nesystem yekufambisa mapaipi isingadhuri uye inoshanda nguva.

    4. Zvakanakira zvakatipoteredza uye kuchengetedzeka kwezvakatipoteredza:

    Kuchinja kushandisa mapaipi esimbi anotenderera eS235 JR mumapaipi kunogonawo kuunza mabhenefiti makuru ezvakatipoteredza. Kugara kwawo kwenguva refu uye kuramba kuora kunoderedza kudiwa kwekutsiviwa nguva nenguva, zvichikonzera kuderera kwemhepo inoburitsa kabhoni uye kugadzirwa kwemarara kushoma. Pamusoro pezvo, kudzokororwa kwesimbi kunoita kuti mapaipi aya ave sarudzo inogara kwenguva refu inoenderana nemisimboti yehupfumi hwakatenderera. Nekushandisa mapaipi esimbi anotenderera eS235 JR, maindasitiri anogona kuve nechokwadi chekuti nzira yekutakura mvura ine hushamwari uye ine mutoro kune zvakatipoteredza, nokudaro ichisimudzira remangwana rakanaka.

    Mhedziso:

    Kushandiswa kweS235 JR spiral steel pombi mumapaipi kunopa mabhenefiti akasiyana-siyana akakosha, anosanganisira kugara kwenguva refu, kuchengetedzeka uye kushanda zvakanaka. Chimiro che spiral welded chinovimbisa kunaka kwechimiro chayo uye chinopa kuendeswa kwemvura kwakavimbika kumaindasitiri akasiyana-siyana. Nekushandisa matekinoroji epamusoro akadai seaya, tiri kugadzira nzira yemapaipi anochengetedza uye akavimbika.
