    Ukuqonda Ukubaluleka Kwepayipi Legesi Yemvelo Lekhwalithi: I-X42 SSAW Pipe, ASTM A139 kanye ne-EN10219

    Ukuqonda Ukubaluleka Kwepayipi Legesi Yemvelo Lekhwalithi: Ipayipi le-X42 SSAW, i-ASTM A139 kanye ne-EN10219 Isithombe Esifakiwe
    • Ukuqonda Ukubaluleka Kwepayipi Legesi Yemvelo Lekhwalithi: I-X42 SSAW Pipe, ASTM A139 kanye ne-EN10219

    Incazelo emfushane:

    Uma kuziwa ekuthuthweni kwegesi yemvelo, izinhlelo zamapayipi zidlala indima ebalulekile ekuqinisekiseni ukulethwa okuphephile nangempumelelo kwalo mthombo oyigugu.ipayipi legesi yemvelo ukukhetha kuyisinqumo esibucayi njengoba sithinta ngokuqondile ukuthembeka nokuphepha kwayo yonke inethiwekhi yokusabalalisa igesi.Kule bhulogi, sizocubungula ukubaluleka kwepayipi legesi yemvelo elisezingeni eliphezulu, sigxile kwipayipi le-X42 SSAW, i-ASTM A139, ne-EN10219.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

     X42I-SSAWipayipiluhlobo lwepayipi legesi yemvelo elivame ukusetshenziswa embonini kawoyela negesi.Ikhiqizwa kusetshenziswa inqubo ye-arc welding engaphansi kwamanzi ekhiqiza amapayipi ekhwalithi ephezulu futhi ahlala isikhathi eside.Ipayipi le-X42 SSAW linamandla aphezulu kanye nezakhiwo zamakhemikhali ezinhle kakhulu, okulenza lifanelekele izidingo ezidingekayo zokuthuthwa kwegesi yemvelo.Ukumelana kwayo okuhle kakhulu nokugqwala nokuqhekeka kuyenza ibe yinketho yokuqala kumaphrojekthi wokwakha amapayipi.

     I-ASTM A139kungenye indinganiso ebalulekile yamapayipi egesi yemvelo.Lokhu kucaciswa kuhlanganisa i-electrofusion (arc) eshiselwe ipayipi lensimbi eliqondile noma elivunguzayo elisetshenziselwa ukudlulisa amagesi, umusi, amanzi nolunye uketshezi.Ipayipi le-ASTM A139 laziwa ngokuthembeka nokusebenza kwesikhathi eside ngaphansi kwezimo zokusebenza ezinzima.Lawa mapayipi aklanyelwe ukumelana nezingcindezi eziphezulu kanye nokuguquguquka kwezinga lokushisa, okuwenza alungele ukudluliswa kwegesi yemvelo nokusetshenziswa kokusabalalisa.

     I-EN10219iyindinganiso yaseYurophu ecacisa izimo zobuchwepheshe zokulethwa kwezingxenye ezingenalutho zesakhiwo esishiselwe okubandayo zensimbi engeyona ingxubevange nensimbi ecolisekile.Nakuba i-EN 10219 ingalungiselelwe ngokuqondile amapayipi egesi yemvelo, izidingo zayo eziqinile zokuqina, ukunemba kobukhulu kanye nezakhiwo zemishini ziyenza ibe ukukhetha okufanele kumaphrojekthi athile wamapayipi egesi.Ukusebenzisa amapayipi athobela izindinganiso ze-EN10219 kungathuthukisa ubuqotho nempilo yesevisi yesistimu yakho yokusabalalisa igesi yemvelo.

    Ukubaluleka kokukhetha ipayipi legesi yemvelo yekhwalithi akukwazi ukweqiwa.Amapayipi asezingeni eliphansi noma asezingeni eliphansi angabeka engcupheni enkulu endaweni ezungezile, ukuphepha komphakathi kanye nokwethembeka okuphelele kokuhlinzekwa kwegesi.Ngakho-ke, izinsiza zegesi yemvelo, abaqhubi bamapayipi kanye nabaphathi bephrojekthi kumele babeke eqhulwini ukusetshenziswa kwezinto ezifakazelwe nezizinze kahle zamapayipi njengepayipi i-X42 SSAW, i-ASTM A139 ne-EN10219.

    Ipayipi le-SSAW

    Ngokufigqiwe,ipayipi legesi yemveloukukhetha kuyisici esibalulekile sokuklama nokwakhiwa kwamapayipi.Ukucatshangelwa kwekhwalithi, njengamandla ezinto ezibonakalayo, ukumelana nokugqwala, nokuhambisana nezindinganiso zomkhakha, kufanele kuqhube inqubo yokuthatha izinqumo.Ngokukhetha amapayipi athembekile nahloniphekile, njengepayipi le-X42 SSAW, i-ASTM A139, kanye ne-EN10219, ababambiqhaza bangaqinisekisa ukusebenza kwesikhathi eside nokuphepha kwengqalasizinda yokuthutha igesi yemvelo.

    Okokugcina, kubalulekile ukubeka eqhulwini ukusetshenziswa kwamapayipi egesi yemvelo asezingeni eliphezulu ahlangabezana nezindinganiso zemboni futhi anezakhiwo ezidingekayo zemishini namakhemikhali.Ngokukhetha izinketho ezithembekile njengepayipi le-X42 SSAW, i-ASTM A139 ne-EN10219, abaqhubi bamapayipi bangaqinisekisa ubuqotho nokuphepha kwezinhlelo zabo zokusabalalisa igesi yemvelo.
