    I-Spiral Welded Pipes for Underground Gas Pipelines EN10219

    Amapayipi Ashiselwe Okuvunguza Amapayipi Egesi Angaphansi EN10219 Isithombe Esifakiwe
    • I-Spiral Welded Pipes for Underground Gas Pipelines EN10219

    Incazelo emfushane:

    Sethula amapayipi ethu ashiselwe okuvunguzayo ekhwalithi ephezulu, aklanyelwe ukuhlangabezana nezidingo ezidingekayo zokufakwa kwamapayipi egesi angaphansi komhlaba. Lawa mapayipi akhiqizwa ngokucophelela ngokwezindinganiso eziqinile ezibekwe ku-EN 10219, oqinisekisa izidingo eziphakeme kakhulu zokulethwa kobuchwepheshe zezingxenye ezingenalutho ezishiselwe ezakhiwe ngendlela ebandayo ezinsimbi ezingenalo ialloyi nezinsimbi ezicolekileyo.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Eyethuamapayipi ashiselwe asontekileziyisixazululo esifanele samaphrojekthi lapho ukumelana nokugqwala kanye nobuqotho besakhiwo kubalulekile. Inqubo ye-welding eyingqayizivele ye-spiral ayigcini nje ngokuthuthukisa amandla wepayipi, kodwa futhi inikeza indawo engenamthungo, inciphisa ingozi yokuvuza nokuhluleka. Lokhu kubenza bafaneleke ikakhulukazi ezindaweni ezinokhahlo ezivame ukuhlangana nazo ekufakweni ngaphansi komhlaba.

    Izinga le-EN10219 liqinisekisa ukuthi amapayipi ethu akhiqizwa ngokunemba nangekhwalithi, ukuqinisekisa ukuthi angakwazi ukumelana nezingcindezi nezinselelo zokuthutha igesi yemvelo. Ngokugxila ekuqineni nasekuthembekeni, amapayipi ethu ashiselwe okuvunguza aklanyelwe ukuhlinzeka ngokusebenza okuhlala isikhathi eside, ukunciphisa isidingo sokunakekelwa njalo nokushintshwa.

    a. Indlela ye-deoxidation ikhethwe kanje:FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).

    b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N. Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

    Ngaphezu kokwakhiwa kwawo okumazombezombe, la mapayipi anesisindo esincane futhi kulula ukuwaphatha, okwenza ukufakwa kusebenze kahle futhi kungabizi kakhulu. Kungakhathaliseki ukuthi wenza iphrojekthi entsha yokufaka amapayipi noma uthuthukisa isistimu ekhona, amapayipi ethu ashiselwe okugobile anikeza inhlanganisela ephelele yamandla, ukuguquguquka, kanye nokuhambisana nezindinganiso zomkhakha.

    Khetha amapayipi ethu ashiselwe asonte ngezidingo zakho zepayipi legesi elingaphansi komhlaba futhi ujabulele ukuthula kwengqondo okuza nokusebenzisa imikhiqizo ehlangabezanayo.I-EN10219izindinganiso. Themba ukuzibophezela kwethu kukhwalithi nokusebenza ukuze siqinisekise ukuphepha nokusebenza kahle kwengqalasizinda yakho yegesi.
