I-ASME B16.9: iMigangatho yaMazwe ngaMazwe yoFakelo lwe-Welding yeBhut eForged

Umgangatho we-ASME B16.9 ngumgangatho okhutshwe yi-American Society of Mechanical Engineers (ASME) enesihloko esithi “Factory-Made Wrought SteelIiFittings ze-But-welding“.Lo mgangatho uxela iimfuno zemilinganiselo, iindlela zokuvelisa, izixhobo, kunye nokuhlolwa kwentsimbi edityanisiweyo kunye nemigangatho engenamthungo yofakelo lwemilo yokudibanisa kunye nokuguqula isalathiso kunye nobukhulu be.imibhobhokwiinkqubo zemibhobho.

Ikwazisa umxholo ophambili kunye neempawu zomgangatho we-ASME B16.9:

Ubungakanani besicelo:

Umgangatho we-ASME B16.9 usetyenziswa kwintsimbi edityanisiweyo nengenamthungo yofakelo lwemibhobho yemilo esemgangathweni, kubandakanywa ingqiniba, izinciphisi, imibhobho edayamitha elinganayo, iiflange, iitiyi, iminqamlezo, njl., ukudibanisa nokuguqula indlela kunye nobukhulu bemibhobho.
Umgangatho uchaza uluhlu lwedayamitha yegama lezi zifakelo, ukusuka kwi-1/2 intshi (DN15) ukuya kwi-intshi ezingama-48 (DN1200), kunye nobukhulu obuqhelekileyo ukusuka kwi-SCH 5S ukuya kwi-SCH XXS.

I-butt welding inokuba yinkqubo ezenzekelayo okanye eyenziwa ngesandla esetyenziselwa ukudibanisa amaqhekeza esinyithi kunye.Izinto zokuwelda ezimpundu ezibunjiweyo zihlala zilula ngokufanelekileyo;ziyilelwe ngendlela yokuba zikwazi ukudityaniswa ngokuthe ngqo kwenye into efanelekileyo.Nangona kunjalo, ngale nto engqondweni, kufuneka ziphuhliswe kumgangatho othile ukuze zifakwe ngokufanelekileyo kwezinye izixhobo.

Indlela yokuvelisa:

Lo mgangatho uxela iindlela zokwenza intsimbi edityanisiweyo kunye nemigangatho yokufakelwa kwemilo esemgangathweni.
Ukufakwa kwe-welded, iinkqubo zokuvelisa ziquka ukubunjwa okubandayo, ukubunjwa okutshisayo, i-welding, njl.;
Ukufakelwa kwemibhobho engenamthungo, inkqubo yokuvelisa idla ngokuqengqeleka ngokushushu, umzobo obandayo okanye ukubetha ngenqindi okubandayo.

Iimfuno zezinto eziphathekayo:

Umgangatho uchaza iimfuno zezinto eziphathekayo zokufakelwa kombhobho, ukugubungela i-carbon steel, insimbi engenasici, insimbi ye-alloy, njl. Izinto zokufakelwa kombhobho kufuneka zihlangabezane nokubunjwa kweekhemikhali, ukusebenza komatshini kunye neemfuno zepropati ezibonakalayo ezichazwe kumgangatho.

Ukuhlolwa kunye novavanyo:

IUmgangatho we-ASME B16.9ifuna ukuhlolwa okuhlukeneyo kunye neemvavanyo kwizixhobo zokufakelwa kwemibhobho eveliswayo ukuze kuqinisekiswe ukuba umgangatho kunye nokusebenza kwabo kuyahlangabezana neemfuno ezichazwe kumgangatho.
Olu hlolo kunye novavanyo lubandakanya ukuhlolwa kwe-dimensional, ukuhlolwa okubonakalayo, uhlalutyo lwemichiza, uvavanyo lokusebenza komatshini, njl.

Umgangatho we-ASME B16.9 ubonelela ngereferensi ebalulekileyo yoyilo kunye nokwakhiwa kwenkqubo yombhobho.Iqinisekisa ukuba ubukhulu, ukuveliswa kunye nezinto eziphathekayo zokufakelwa kombhobho zihlangabezana neemfuno zobunjineli zokuqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo yombhobho.Xa usebenzisa kunye nokukhetha izixhobo zombhobho, umgangatho we-ASME B16.9 kufuneka ulandelwe ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yombhobho.
