    Kunzwisisa Kukosha Kwemapombi Welding Maitiro eSpiral Steel Pipe Inoshandiswa muMitsetse Yemvura Yepasi

    Kunzwisisa Kukosha Kwemapombi Akakodzera Welding Matanho eSpiral Steel Pipe Inoshandiswa muMitsetse Yemvura Yepasi Inoratidzwa Mufananidzo
    • Kunzwisisa Kukosha Kwemapombi Welding Maitiro eSpiral Steel Pipe Inoshandiswa muMitsetse Yemvura Yepasi

    Tsanangudzo Pfupi:

    Pakuisa mitsara yemvura yepasi pevhu, kushandisa pombi yepamusoro-soro kunokosha kuti uve nechokwadi chekugara kwenguva refu uye kuramba kune zvakatipoteredza zvinhu.Imwe mhando yepombi inowanzoshandiswa kumitsetse yemvura yepasi pevhu inonzi spiral steel pipe.Nekudaro, kungoshandisa mapaipi emhando yepamusoro hakuna kukwana kuti uve nechokwadi chehupenyu hurefu hwepombi dzako dzemvura.Nzira dzakafanira dzemapipe welding dzakakosha pakuona kuti spiral simbi pombi dzinogona kumira pasi pevhu dzakaomarara nekupa mvura yakavimbika.
