Izinga le-ASME B16.9 liyindinganiso ekhishwe yi-American Society of Mechanical Engineers (ASME) enesihloko esithi “Factory-Made Wrought SteelI-Butt-welding Fittings“. Leli zinga licacisa izidingo zobukhulu, izindlela zokukhiqiza, izinto zokwakha, kanye nokuhlolwa kwensimbi eshiselwe kanye nokufakwa komumo okungenamthungo kokuxhuma nokuguqula indlela kanye nosayizi weamapayipiezinhlelweni zamapayipi.
Futhi yethula okuqukethwe okuyinhloko nezici zezinga le-ASME B16.9:
Ububanzi besicelo:
Izinga le-ASME B16.9 lisebenza ekufakweni kwepayipi lensimbi elishiselwe futhi elingenamthungo, okuhlanganisa izindololwane, izinciphisi, amapayipi obubanzi obulinganayo, ama-flange, ama-tee, iziphambano, njll., ekuxhumeni nasekuguquleni isiqondiso nosayizi wamapayipi.
Izinga licacisa ububanzi obuncane bobubanzi balokhu kufakwa, ukusuka ku-1/2 intshi (DN15) ukuya kumayintshi angu-48 (DN1200), kanye nogqinsi olusuka ku-SCH 5S ukuya ku-SCH XXS.
Ukushisela izinqe kungaba inqubo ezenzakalelayo noma eyenziwa ngesandla esetshenziselwa ukuhlanganisa izingcezu zensimbi ndawonye. Izinto zokushisela izinqe ezifojiwe ngokuvamile zilula; aklanywe ngendlela yokuthi akwazi ukushiselwa ngqo kwenye into efakwayo. Kodwa-ke, ngalokhu engqondweni, badinga ukuthuthukiswa ezingeni elithile ukuze bakwazi ukufakwa kahle kwezinye izesekeli.
Indlela yokukhiqiza:
Leli zinga licacisa izindlela zokwenza izinsimbi zomumo oshiselwe insimbi nezingenamthungo.
Okufakwayo okushiselwe, izinqubo zokukhiqiza zifaka ukwakheka okubandayo, ukwakheka okushisayo, ukushisela, njll.;
Ukuze kufakwe amapayipi angenamthungo, inqubo yokukhiqiza ivamise ukugingqika okushisayo, ukudweba okubandayo noma ukubhoboza okubandayo.
Izidingo zezinto:
Izinga licacisa izidingo zezinto ezibonakalayo zokufakwa kwamapayipi, okumboza insimbi ye-carbon, insimbi engagqwali, insimbi yengxubevange, njll. Izinto ezifakwayo zamapayipi kufanele zihlangabezane nokwakheka kwamakhemikhali, ukusebenza kwemishini kanye nezidingo zempahla ebonakalayo eshiwo ezingeni.
Ukuhlola nokuhlola:
II-ASME B16.9 ejwayelekilekudinga ukuhlolwa nokuhlolwa okuhlukahlukene ekufakweni kwamapayipi akhiqiziwe ukuze kuqinisekiswe ukuthi ikhwalithi nokusebenza kwawo kuhlangabezana nezidingo ezibalulwe ezingeni.
Lokhu kuhlola nokuhlola kufaka phakathi ukuhlolwa kobukhulu, ukuhlolwa okubonakalayo, ukuhlaziya ukwakheka kwamakhemikhali, ukuhlolwa kokusebenza kwemishini, njll.
Izinga le-ASME B16.9 linikeza ireferensi ebalulekile yokuklama nokwakhiwa kwesistimu yamapayipi. Iqinisekisa ukuthi ubukhulu, ukukhiqizwa kanye nempahla yokufakwa kwamapayipi kuhlangabezana nezidingo zobunjiniyela ukuze kuqinisekiswe ukuphepha nokuthembeka kwesistimu yamapayipi. Uma usebenzisa futhi ukhetha ukufakwa kwamapayipi, izinga le-ASME B16.9 kufanele lilandelwe ukuze kuqinisekiswe ukusebenza okuvamile kwesistimu yamapayipi.
