LIYINI I-ASME B16.9 IZINGA?

Yiziphi ezinye zezingxenye ezivame kakhulu i-pipe-fitter engazisebenzisa lapho ishisela?Izinsimbi ezishiselwe izinqe, kunjalo.Kodwa ingabe wake wazibuza ukuthi kungani ngokuvamile kulula kangaka ukuthola okokufaka okusebenzayo?

Uma kuziwa ekufakweni kwe-butt welding eyenziwe efektri, kunezindinganiso ezithile okudingeka zihlangatshezwe ngesikhathi sokukhiqiza.Okudume kakhulu yi-ANSI ne-ASME.Ake sibheke izinga le-ASME B 16.9 nokuthi lihluke kanjani kuzinga le-ANSI.

I-ASME B 16.9:Yenziwe IfekthriI-Wrought Butt Welding Fittings

I-ASME B 16.9 isethwe yi-American Society of Mechanical Engineers.I-B 16.9 ibhekisela ezintweni ezifakwa embonini zokushisela izinqe.I-ASME B 16.9 ibusa ububanzi, izilinganiso zokucindezela, usayizi, ukumaka, izinto ezibonakalayo, izilinganiso ezifanele, ama-surface contour, ukulungiswa kokuphela, ukuhlolwa kobufakazi bomklamo, izivivinyo zokukhiqiza, nokubekezelela.Lokhu kumiswa kuqinisekisa ukuthi okokufaka kukhiqizwa ngendlela okufanele kube ngayo kububanzi nezicaciso, okwenza kube lula ukuhlanganisa izingxenye ezintsha ezingxenyeni ezikhona, nokuqinisekisa ukuphepha, amandla, nokuzinza.

Ukushisela izinqe kungaba inqubo ezenzakalelayo noma yesandla, esetshenziselwa ukuhlanganisa izingcezu zensimbi.Izinto ezifakwa ezinqeni zokushisela ngokuvamile zilula;aklanywe ngendlela yokuthi akwazi ukushiselwa ngqo kokunye ukufaka.Unalokho engqondweni, nokho, zidinga ukuthuthukiswa kumazinga athile, ukuze zikwazi ukungena ngokufanele kwezinye izinto ezifakwayo.Izinhlobo ze-butt weld fitting zingabandakanyaizindololwane, amakepisi, tee, izinciphisi, kanye nezitolo.

Ngenxa yokuthi i-buttwelding ingenye yezindlela ezivame kakhulu zokushisela kanye nezindlela zokuhlanganisa, onjiniyela bemishini kungenzeka basebenzise futhi basebenze ngokufakwa kwe-buttweld okwenziwe efekthri kaningi.Abakhiqizi bokufakwa kwe-butt weld bazodinga ukuzikhathaza ngamazinga kanye nokucaciswa.

I-ANSI vs ASME Amazinga

Amazinga we-ANSI vs ASME kwezinye izingxenye zefekthri angahluka.Ngakho-ke, onjiniyela bangase bafune ukwazi ukuthi basebenzela izindinganiso ze-ANSI noma ze-ASME, njengoba amazinga e-ASME ngokuvamile ecaciswe kakhulu futhi amazinga e-ANSI angase ahlanganise kakhulu.I-ASME iyindinganiso ebilokhu ichaza ukufakwa kwamapayipi kusukela ekuqaleni kwawo-1920.Kuzinhlelo zokusebenza eziningi, ukulandela izindinganiso ze-ASME kuzophinde kulandele izindinganiso ze-ANSI.

I-ANSI isethwe yi-American National Standards Institute.I-ANSI ilawula izimboni eziningi kakhulu, kuyilapho i-ASME yakhelwe ngokukhethekile amaboyela, imikhumbi yokucindezela, nezinye izindawo ezifanayo.Ngakho, nakuba okuthile kungase kuhlangabezane nezindinganiso ze-ANSI, kungase kungafinyeleli amazinga e-ASME;Amazinga e-ASME angase acace kakhulu noma aqine.Uma kukhulunywa ngezinga le-B16.9, nokho, amazinga e-ANSI kanye ne-ASME maningi amathuba okuthi afane.

Amazinga nemithethonqubo ihlale ibalulekile, ikakhulukazi kokuthile okunjengokucindezela okukhulu njengamapayipi nama-boilers.Ngenxa yokuthi izindinganiso zingashintsha, kubalulekile ukuthi izinhlangano zinike isikhathi esithile ukuze zizibuyekeze ngezinguquko nezengezo.Kwa-Steel Forgings, sihlala sisebenzela ukuqinisekisa ukuthi izingcezu zethu zihlangabezana nazo zonke izindinganiso ezidingekayo - nokuthi zihamba ngaphezu kwalokho ngokwekhwalithi nokuvumelana.
