    Incazelo emfushane:

    Uma kukhulunywa ngokuhamba kwegesi yemvelo, amasistimu wepayipi kudlala indima ebalulekile ekuqinisekiseni ukulethwa okuphephile nokusebenzayo kwalesi sisetshenziswa esiyigugu.Ipayipi lemvelo lemvelo Ukukhetha kuyisinqumo esibucayi njengoba kuthinta ngqo ukuthembeka nokuphepha kwalo lonke inethiwekhi yokusatshalaliswa kwegesi. Kule bhulogi, sizokwelulela ukubaluleka kwepayipi lemvelo lemvelo lekhwalithi, ligxile ku-X42 SSAW Pipe, ASTM A139, ne-EN10219.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

     X42I-SSAWipayipiUhlobo lwepayipi lemvelo lemvelo elivame ukusetshenziswa embonini kawoyela negesi. Kwenziwa kusetshenziswa inqubo ye-welding engaphansi ye-arc ekhiqiza amapayipi aphezulu aphezulu futhi aqinile. I-X42 SSAW Pipe inamandla aphezulu nezakhiwo ezinhle zamakhemikhali, okwenza zilungele izidingo ezifunwayo zokuhamba kwegesi yemvelo. Ukumelana kwayo okuhle kakhulu kokugqwala nokuqhekeka kwenza kube ukukhetha kokuqala kwamaphrojekthi wokwakha amapayipi.

     I-ASTM A139kungenye indinganiso ebalulekile yamapayipi egesi yemvelo. Lokhu okucacisiwe kufaka i-electrofulsiul (arc) i-weldied iqonde noma i-spiral seam ngepayipi esetshenziselwe ukudlulisa amagesi, umusi, amanzi nezinye iziphuzo. I-ASTM A139 Ipayipi yaziwa ngokuthembeka kwayo kanye nokusebenza kwesikhathi eside ngaphansi kwezimo ezisebenzayo ezinzima. Lawa mapayipi aklanyelwe ukubekezelela izingcindezi eziphakeme nokushintshashintsha kwezinga lokushisa, ukuzenza elungele ukudluliswa kwegesi yemvelo kanye nokusabalalisa.

     En10219Ingabe indinganiso yaseYurophu ecacisa izimo zokulethwa kwezobuchwepheshe zezinhlaka ezakhiwe njengensimbi ezibandayo zensimbi engeyona eyensimbi yensimbi nensimbi emihle. Yize i-EN10219 ayihambelani ngokuqondile ngamapayipi egesi yemvelo, izidingo zayo eziqinile zokuqina, ukunemba okunobukhulu kanye nezakhiwo zemishini zenza kube yisinqumo esifanele samaphrojekthi athile epayipi. Kusetshenziswa amapayipi ahambisana namazinga we-EN10219 angathuthukisa ubuqotho obuphelele kanye nempilo yenkonzo yohlelo lwakho lokusabalalisa igesi yemvelo.

    Ukubaluleka kokukhetha ipayipi lemvelo lekhwalithi lekhwalithi alikwazi ukweqiwa. Amapayipi asezingeni eliphansi noma aphansi angabeka izingozi ezinkulu emvelweni, ukuphepha komphakathi kanye nokwethenjwa ngokuphelele kwegesi. Ngakho-ke, izinsiza zegesi zemvelo, abasebenza ngepayipi kanye nabaphathi bephrojekthi kumele babeke phambili ukusetshenziswa kwezinto zepayipi ezifakazelwe nezisungulwe kahle njenge-X42 SSAW Pipe, ASTM A139 ne-EN10219.

    Ipayipi le-SSAW

    Ngokufigqiwe,Ipayipi lemvelo lemveloUkukhetha kuyisici esibalulekile sokwakhiwa kwepayipi nokwakha. Ukucatshangelwa kwekhwalithi, njengokuqina kwezinto ezibonakalayo, ukumelana nokugqwala, kanye nokuhambisana namazinga embonini, kufanele kuqhube inqubo yokwenza izinqumo. Ngokukhetha amapayipi athembekile futhi ahlonishwayo, njenge-X42 SSAW PIPELINE, ASTM A139, kanye ne-EN10219, ababambiqhaza bangaqinisekisa ukusebenza kwesikhathi eside kanye nokuphepha kwengqalasizinda yezokwelashwa kwegesi yemvelo.

    Okokugcina, kubalulekile ukubeka phambili ukusetshenziswa kwamapayipi wekhwalithi ephezulu yemvelo ehlangabezana namazinga embonini futhi ube nezindawo ezidingekayo zemishini nezamakhemikhali. Ngokukhetha izinketho ezinokwethenjelwa njenge-X42 SSAW PIPEline, ASTM A139 ne-EN10219, opharetha bamapayipi bangaqinisekisa ubuqotho besikhathi eside nezinhlelo zabo zemvelo zokusabalalisa igesi.
