Izinga le-A106 libhekisela ku-I-ASTM A106/A106Mindinganiso, okuyindinganiso yomkhiqizo wamapayipi ensimbi yekhabhoni angenamthungo ekhishwe yi-American Society for Testing and Materials (ASTM International). Le ndinganiso ichaza izidingo zokusetshenziswa kwamapayipi ensimbi yekhabhoni angenamthungo ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu.
Izinga le-A106 lisebenza ezindaweni zesevisi ezishisa kakhulu ezimbonini ezijwayelekile, njengokucwengisisa uphethiloli, imboni yamakhemikhali, iziteshi zamandla, ama-boiler, izinhlelo zokushisa kanye namapayipi anomfutho ophezulu kanye neminye imikhakha. Lihlanganisa amazinga amaningana epayipi lensimbi yekhabhoni, kufaka phakathi amazinga e-A, B, kanye ne-C.
Ngokwezinga le-A106, amapayipi ensimbi yekhabhoni angenamthungo kufanele abe nokwakheka kwamakhemikhali athile kanye nezakhiwo zemishini. Izidingo zokwakheka kwamakhemikhali zifaka kakhulu okuqukethwe kwekhabhoni, okuqukethwe kwe-manganese, okuqukethwe kwe-phosphorus, okuqukethwe kwesulfure kanye nokuqukethwe kwethusi. Izidingo zezakhiwo zemishini zifaka phakathi amandla okudonsa, amandla okukhiqiza, kanye nokwelulwa, phakathi kokunye. Ngaphezu kwalokho, usayizi, isisindo kanye nokuphambuka okuvunyelwe kwamapayipi kucacisiwe.
Izinga le-A106 lidinga ukuthi amapayipi ensimbi yekhabhoni angenamthungo akwazi ukumelana nokucindezeleka ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu, futhi abe nokumelana okuhle kakhulu nokugqwala kanye nokumelana nokuqhekeka kwe-hydrogen. Inqubo yayo yokukhiqiza ifaka phakathi ukudweba okubandayo, ukugoqa okubandayo, ukugoqa okushisayo noma ukwanda kokushisa, njll., ukuqinisekisa ukuthi izindawo zangaphakathi nezangaphandle zepayipi zibushelelezi futhi azinazo iziphambeko.
Ngokwezinhlinzeko zendinganiso ye-A106, amapayipi ensimbi yekhabhoni angenamthungo kufanele ahlolwe futhi ahlolwe ngochungechunge lokuhlolwa njengokuhlaziywa kwamakhemikhali, ukuhlolwa kokusebenza komshini, ukuhlolwa okubonakalayo, ukulinganiswa kobukhulu bodonga, ukuhlolwa kokucindezela kanye nokuhlolwa okungabhubhisi ukuqinisekisa ukuthi ikhwalithi yawo ihlangabezana nezidingo ezijwayelekile.
Ekuphetheni, indinganiso ye-A106 iyindinganiso ebalulekile yomkhiqizo wepayipi lensimbi yekhabhoni engenamthungo, echaza ukwakheka kwamakhemikhali, izakhiwo zemishini kanye nezidingo zenqubo yokukhiqiza yamapayipi ensimbi yekhabhoni, kanye nezidingo zokulawula ikhwalithi nokuhlola. Ukuhambisana naleli zinga kungaqinisekisa ukusetshenziswa okuthembekile kwamapayipi ensimbi yekhabhoni engenamthungo ezindaweni zokushisa okuphezulu kanye nokucindezela okuphezulu.
Umkhiqizo othengwe yikhasimende kulokhu uyipayipi lensimbi yekhabhoni elingenamthungo i-ASTM A106 GR.C. Ake ngikubonise imininingwane ethile yokulinganisa kanye nokulawulwa kwekhwalithi yomkhiqizo wonke.
