    Spiral Musono Steel Pipe Yepasi Pevhu Mapaipi Emvura

    Pipe yeSimbi yeMusono weSpiral yeMapaipi emvura epasi pevhu Mufananidzo wakaratidzwa
    • Spiral Musono Steel Pipe Yepasi Pevhu Mapaipi Emvura

    Tsananguro pfupi:

    Tichisuma yedupombi yemusono inotenderera yemapaipi emvura ari pasi pevhu. Zvivakwa zveiyi nzira itsva ipombi yemusono inotenderera, yakasungirirwa nehunyanzvi ichishandisa tekinoroji yepamusoro-soro yekushongedza mapaipi esimbi pamusika.


    Ruzivo rweChigadzirwa

    Matagi eChigadzirwa

    Iyopombi yemvura yepasi pevhuipombi yesimbi inotenderera yakagadzirwa neautomatic double-waya double-sided submited arc welding process. Pombi iyi yakagadzirwa ne strip steel coils uye inoburitswa patembiricha yakafanana kuti ive nechokwadi chekuti inogara kwenguva refu uye kuti inogara kwenguva refu.

    Kugadzirwa kwepombi iyi kwakabatana nedenderedzwa resimbi kunoita kuti ive yakasimba uye inodzivirira kumanikidzwa, zvichiita kuti ive sarudzo yakakwana yemvura iri pasi pevhu.

    Pamusoro pekusimba uye kugara kwenguva refu, mapaipi emvura ari pasi pevhu akagadzirwa kuti zvive nyore kuisa. Kuvaka musono wedenderedzwa kunochinjika uye kunochinjika, zvichiita kuti zvive nyore kufamba uye kuisa mapaipi munzvimbo dzakaoma. Izvi zvinoreva kuti unogona kuisa mapaipi nekukurumidza uye nemazvo, uchichengetedza nguva nemari yevashandi.

    Pamusoro pezvo, kushandiswa kwezvinhu zvemhando yepamusoro uye tekinoroji yepamusoro yekunamira mvura inoita kuti mapaipi emvura ari pasi pevhu arambe akasimba kubva mukuora nengura. Izvi zvinoreva kuti ichachengetedza kushanda kwayo kwemakore, kunyangwe mumamiriro ezvinhu akaoma pasi pevhu.

    Maitiro Ekubatanidza Mapaipi
    Pombi yepolyurethane yakagadzirwa

    Mapombi edu emvura ari pasi pevhu anowanikwa muhukuru hwakasiyana-siyana kuti aenderane nezvinodiwa neprojekiti yenyu. Kunyangwe muri kuisa mvura diki yemumba kana sisitimu huru yeindasitiri, tine pombi yakakunakirai. Chikwata chedu chenyanzvi chinogonawo kupa mazano nerutsigiro rwakagadzirirwa iwe kuti chikubatsire kusarudza pombi dzinonyatsoenderana nezvaunoda.

    Kana zvasvika kune masisitimu emvura ari pasi pevhu, unoda pombi yaunogona kuvimba nayo. Nekuvakwa kwejoini dzakatenderedza mativi, zvinhu zvemhando yepamusoro uye welding yehunyanzvi, mapaipi edu emvura ari pasi pevhu akakodzera chero network yekupa mvura. Inogara kwenguva refu, yakavimbika uye iri nyore kuisa, pombi iyi ichagara kwenguva refu, ichikupa rugare rwepfungwa uye kushanda zvakanaka.

    Pamwe chete, mapaipi emusono anotenderera isarudzo yakanaka kune chero munhu anoda mhinduro yekupa mvura yemhando yepamusoro, yakavimbika, uye inogara kwenguva refu. Nekugadzirwa kwayo kwemusono unotenderera uye nehunyanzvi.kusona mapaipi esimbi, pombi iyi inopa simba risingaenzaniswi, kuchinjika uye kuramba ngura. Usakanganise kunaka kwemvura iri pasi pevhu - sarudza pombi dzemvura dziri pasi pevhu semhinduro yaunogona kuvimba nayo.
