    Incazelo emfushane:

    Uma kukhulunywa ngokuthuthwa kwegesi yemvelo, izinhlelo zamapayipi zidlala indima ebalulekile ekuqinisekiseni ukulethwa okuphephile nokuphumelelayo kwale nsiza eyigugu.ipayipi legesi yemvelo Ukukhetha kuyisinqumo esibalulekile njengoba kuthinta ngqo ukuthembeka nokuphepha kwenethiwekhi yonke yokusatshalaliswa kwegesi. Kule bhulogi, sizogxila ekubalulekeni kwepayipi legesi yemvelo elisezingeni eliphezulu, sigxile epayipini le-X42 SSAW, i-ASTM A139, kanye ne-EN10219.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

     X42I-SSAWipayipiuhlobo lwepayipi legesi yemvelo elivame ukusetshenziswa embonini kawoyela negesi. Lakhiwa kusetshenziswa inqubo yokushisela i-arc engaphansi kwamanzi ekhiqiza amapayipi asezingeni eliphezulu futhi ahlala isikhathi eside. Ipayipi le-X42 SSAW linamandla aphezulu kanye nezakhiwo zamakhemikhali ezinhle kakhulu, okwenza lifaneleke kahle izidingo ezidingayo zokuthuthwa kwegesi yemvelo. Ukumelana kwalo okuhle kakhulu nokugqwala nokuqhekeka kwenza kube ukukhetha kokuqala kwamaphrojekthi okwakha amapayipi.

     I-ASTM A139kungenye indinganiso ebalulekile yamapayipi egesi yemvelo. Le ncazelo ihlanganisa ipayipi lensimbi eliqondile noma eliyindilinga elihlanganisiwe elisetshenziswa ukudlulisa amagesi, umusi, amanzi kanye nolunye uketshezi. Ipayipi le-ASTM A139 laziwa ngokuthembeka kwalo kanye nokusebenza kwalo isikhathi eside ngaphansi kwezimo zokusebenza ezinzima kakhulu. Lawa mapayipi aklanyelwe ukumelana nokucindezeleka okuphezulu kanye nokushintshashintsha kwezinga lokushisa, okwenza afaneleke kakhulu ekudlulisweni nasekusatshalalisweni kwegesi yemvelo.

     EN10219iyindinganiso yaseYurophu echaza izimo zokulethwa kobuchwepheshe zezingxenye ezingenalutho ezakhiwe ngokubandayo zensimbi engeyona i-alloy kanye nensimbi ecolekile. Nakuba i-EN10219 ingenziwanga ngqo ngamapayipi egesi yemvelo, izidingo zayo eziqinile zokuqina, ukunemba kobukhulu kanye nezakhiwo zemishini zenza kube ukukhetha okufanele kumaphrojekthi athile epayipi legesi. Ukusebenzisa amapayipi ahambisana nezindinganiso ze-EN10219 kungathuthukisa ubuqotho kanye nokuphila kwenkonzo kwesistimu yakho yokusatshalaliswa kwegesi yemvelo.

    Ukubaluleka kokukhetha ipayipi legesi yemvelo elisezingeni eliphezulu akunakugcizelelwa ngokweqile. Amapayipi asezingeni eliphansi noma angaphansi kwezinga eliphezulu angadala izingozi ezinkulu emvelweni, ukuphepha komphakathi kanye nokuthembeka okuphelele kokuhlinzekwa kwegesi. Ngakho-ke, izinsiza zegesi yemvelo, abaqhubi bamapayipi kanye nabaphathi bamaphrojekthi kumele babeke phambili ukusetshenziswa kwezinto zamapayipi eziqinisekisiwe nezisungulwe kahle njengepayipi le-X42 SSAW, i-ASTM A139 kanye ne-EN10219.

    Ipayipi le-SSAW

    Ngokufigqiwe,ipayipi legesi yemveloUkukhetha kuyisici esibalulekile sokuklama nokwakha amapayipi. Ukucatshangelwa kwekhwalithi, njengokuqina kwezinto, ukumelana nokugqwala, kanye nokuhambisana nezindinganiso zemboni, kufanele kuholele inqubo yokwenza izinqumo. Ngokukhetha amapayipi athembekile nathembekile, njengepayipi le-X42 SSAW, i-ASTM A139, kanye ne-EN10219, ababambiqhaza bangaqinisekisa ukuthi ingqalasizinda yezokuthutha igesi yemvelo ihlala isikhathi eside futhi iphephile.

    Okokugcina, kubalulekile ukubeka phambili ukusetshenziswa kwamapayipi egesi yemvelo asezingeni eliphezulu ahlangabezana nezindinganiso zemboni futhi anezakhiwo ezidingekayo zemishini namakhemikhali. Ngokukhetha izinketho ezinokwethenjelwa njengepayipi le-X42 SSAW, i-ASTM A139 kanye ne-EN10219, abaqhubi bamapayipi bangaqinisekisa ubuqotho besikhathi eside kanye nokuphepha kwezinhlelo zabo zokusatshalaliswa kwegesi yemvelo.
