    Mapaipi eApi 5l Line Grade B Kusvika X70 Kubva 219mm Kusvika 3500mm Mufananidzo Unoratidzwa
    • Mapaipi eApi 5l Line Grade B kusvika X70 Od Kubva 219mm Kusvika 3500mm

    Tsananguro pfupi:

    Mutemo uyu ndewekupa mwero wekugadzira masisitimu emapaipi ekufambisa mvura, gasi nemafuta mumaindasitiri emafuta negasi rechisikigo.

    Kune mazinga maviri ekugadzirwa kwechigadzirwa, PSL 1 nePSL 2, PSL 2 ine zvinodiwa zve carbon equivalent, notch simplicity, maximum goeth strength uye tensile strength.

    Giredhi B, X42, X46, X52, X56, X60, X65, X70 uye X80.

    Cangzhou Spiral Steel pipes group co.,ltd inopa mapaipi eSAWH ane giredhi kubva kuAPI B kusvika kuX70, takawana chitupa cheAPI 5L makore apfuura uye ikozvino mapaipi edu anoshandiswa zvakanyanya neCNPC, CPECC kumapurojekiti avo emapaipi.

    tsananguro yechigadzirwa1

    Pombi inofanira kumira bvunzo ye hydrostatic pasina kubuda nemusono we weld kana muviri wepombi.
    Majoini haafanirwe kuongororwa ne hydrostatic, chero bedzi zvikamu zvepaipi zvinoshandiswa pakuisa chiratidzo pajoini zvakaedzwa ne hydrostatic zvisati zvaitika.

    Kutevedzana:
    Pamuchina wePSL 1, mugadziri anofanira kutanga nekutevera nzira dzakanyorwa dzekuchengetedza:
    Kuzivikanwa kwekupisa kusvika bvunzo dzese dze chmical dzaitwa uye kutevedzera zvinodiwa zvakatarwa kwaratidzwa.
    Kuzivikanwa kweyuniti yekuedza kusvika bvunzo dzese dzemakanika dzaitwa uye kutevedzera zvinodiwa zvakatarwa kwaratidzwa.
    Pamapaipi ePSL 2, mugadziri anofanira kutanga nekutevera maitiro akanyorwa ekuchengetedza hunhu hwekupisa uye hunhu hwechiyedzo chepombi yakadaro. Maitiro akadaro achapa nzira dzekutevera hurefu hwepombi kusvika kuyuniti chaiyo yekuyedza uye mhedzisiro yekuyedza kwemakemikari yakabatana.
