YINTONI UMGANGATHO WE-ASME B16.9?

Zeziphi ezinye zezona nxalenye zixhaphakileyo umbhobho-fitter onokuzisebenzisa xa uwelda?Iifittings ezidityanisiweyo nge-butt, kunjalo.Kodwa ngaba ukhe wazibuza ukuba kutheni kudla ngokuba lula ukufumana izinto ezisebenzayo?

Xa kuziwa kwi-fectory-made butt welding fittings, kukho imigangatho ethile ekufuneka ihlangabezane nayo ngexesha lokuvelisa.Ezona zidumileyo zi-ANSI kunye ne-ASME.Makhe sijonge umgangatho we-ASME B 16.9 kwaye wohluke njani kumgangatho we-ANSI.

ASME B 16.9:IFactory-YenziweIiFittings zeWelding ye-But esebenzayo

I-ASME B 16.9 isetwe nguMbutho waseMelika weeNjineli zoomatshini.I-B 16.9 ibhekisa kwizixhobo zokuwelda iimpundu ezenziwe efektri.I-ASME B 16.9 ilawula umda, imilinganiselo yoxinzelelo, ubungakanani, ukumakishwa, imathiriyeli, imilinganiselo efanelekileyo, iicontours zomphezulu, ukulungiswa kwesiphelo, iimvavanyo zobungqina boyilo, iimvavanyo zemveliso, kunye nokunyamezela.Oku kulungelelaniswa kuqinisekisa ukuba ukufakwa kuveliswa njengoko kufuneka kube kububanzi kunye neenkcukacha, okwenza kube lula ukudibanisa iinxalenye ezintsha kwiindawo ezikhoyo, kunye nokuqinisekisa ukhuseleko, amandla kunye nokuzinza.

I-butt welding inokuba yinkqubo ezenzekelayo okanye eyenziwa ngesandla, esetyenziselwa ukudibanisa amaqhekeza esinyithi.Izinto zokuwelda ngeempundu zilula ngokufanelekileyo;ziyilwe ngendlela yokuba zikwazi ukudityaniswa ngokuthe ngqo kwenye into edibanisayo.Unaloo nto engqondweni, nangona kunjalo, kufuneka ziphuhliswe kwimigangatho ethile, ukuze zikwazi ukungena ngokuchanekileyo kwezinye izinto.Iintlobo ze-butt weld fitting zingabandakanyaiingqiniba, iminqwazi, iithiyi, abanciphisi, kunye neevenkile.

Ngenxa yokuba i-buttwelding yenye yezona ndlela zixhaphakileyo zokuwelda kunye neendlela zokujoyina, iinjineli zoomatshini kusenokwenzeka ukuba zisebenzise kwaye zisebenze ngofakelo lwebuttweld olwenziwe ngumzi-mveliso rhoqo.Abavelisi bokufakwa kwe-butt weld kuya kufuneka bazixhalabise ngemigangatho kunye neenkcukacha.

I-ANSI vs ASME imiGangatho

Imigangatho ye-ANSI vs ASME yezinye iindawo ezenziwe ngefektri inokwahluka.Ke, iinjineli zinokufuna ukwazi ukuba zisebenza kwimigangatho ye-ANSI okanye ye-ASME, njengoko imigangatho ye-ASME icace ngakumbi kwaye imigangatho ye-ANSI inokubandakanya ngakumbi.I-ASME ngumgangatho obuchaza ukufakwa kwemibhobho ukususela ekuqaleni koo-1920.Kwizicelo ezininzi, ukulandela imigangatho ye-ASME kuya kulandela imigangatho ye-ANSI.

I-ANSI ibekwe yi-American National Standards Institute.I-ANSI ilawula amashishini amaninzi amaninzi, ngelixa i-ASME yenzelwe ngokukodwa iibhoyili, iinqanawa zoxinzelelo, kunye nezinye iindawo ezifanayo.Ke, ngelixa into inokuhlangabezana nemigangatho ye-ANSI, isenokungafikeleli imigangatho ye-ASME;Imigangatho ye-ASME inokuthi icace ngakumbi okanye ingqongqo.Xa kuziwa kumgangatho we-B16.9, nangona kunjalo, imigangatho ye-ANSI kunye ne-ASME inokuthi ifane.

Imigangatho kunye nemimiselo ihlala ibalulekile, ngokukodwa kwinto enjengoxinzelelo oluphezulu njengemibhobho kunye neebhoyili.Ngenxa yokuba imigangatho inokutshintsha, kubalulekile ukuba imibutho inike ixesha elithile ukuze ihlaziye utshintsho kunye nokongezwa.Kwi-Steel Forgings, sihlala sisebenzela ukuqinisekisa ukuba iziqwenga zethu ziyahlangabezana nayo yonke imigangatho efunekayo-kwaye zihamba ngaphezulu nangaphaya ngokomgangatho kunye nokungaguquguquki.
