Izinga le-A106 libhekise ku-I-ASTM A106/A106Mokujwayelekile, okuyindinganiso yomkhiqizo yamapayipi ensimbi yensimbi engenamthungo ekhishwe yi-American Society for Testing and Materials (ASTM International). Leli zinga licacisa izidingo zokusetshenziswa kwamapayipi ensimbi ensimbi engenamthungo ngaphansi kwamazinga okushisa aphezulu kanye nezimo zengcindezi ephezulu.
Izinga le-A106 lisebenza ezindaweni ezihlinzeka ngezinga lokushisa eliphezulu ezimbonini ezijwayelekile, njengokuhluza i-petroleum, imboni yamakhemikhali, iziteshi zikagesi, ama-boilers, amasistimu wokushisisa kanye namapayipi anomfutho ophezulu kanye neminye imikhakha. Ihlanganisa amamaki amaningana epayipi lensimbi ye-carbon, kuhlanganise namamaki A, B, no-C.
Ngokwezinga le-A106, amapayipi ensimbi e-carbon angenamthungo kufanele abe nokwakheka kwamakhemikhali athile kanye nezakhiwo zemishini. Izidingo zokwakheka kwamakhemikhali ikakhulukazi zihlanganisa okuqukethwe kwekhabhoni, okuqukethwe kwe-manganese, okuqukethwe kwe-phosphorus, okuqukethwe kwesibabule kanye nethusi. Izidingo zezakhiwo zikamshini zifaka amandla aqinile, amandla okukhiqiza, nobude, phakathi kokunye. Ngaphezu kwalokho, ubukhulu, isisindo kanye nokuphambuka okuvumelekile kwamapayipi kucacisiwe.
Izinga le-A106 lidinga ukuthi amapayipi ensimbi ensimbi angenamthungo kufanele akwazi ukumelana nengcindezi ngaphansi kwezimo zokushisa eziphakeme nezimo zokucindezela okukhulu, futhi abe nokumelana nokugqwala okuhle kakhulu nokumelana nokuqhekeka kwe-hydrogen. Inqubo yokukhiqiza yayo ihlanganisa ukudweba okubandayo, ukugoqa okubandayo, ukugoqa okushisayo noma ukunwetshwa kwe-thermal, njll., ukuze kuqinisekiswe ukuthi izindawo zangaphakathi nangaphandle zepayipi zibushelelezi futhi azinawo amaphutha.
Ngokwezinhlinzeko zezinga le-A106, amapayipi ensimbi angenamthungo kufanele ahlolwe futhi ahlolwe njengokuhlaziywa kwamakhemikhali, ukuhlolwa kokusebenza kwemishini, ukuhlolwa okubonakalayo, ukukala ukushuba kodonga, ukuhlolwa kwengcindezi nokuhlolwa okungabhubhisi ukuze kuqinisekiswe ikhwalithi yawo ihlangabezana izidingo ezijwayelekile.
Sengiphetha, izinga le-A106 liyindinganiso ebalulekile yomkhiqizo wepayipi lensimbi yensimbi engenamthungo, elicacisa ukwakheka kwamakhemikhali, izakhiwo zemishini kanye nezidingo zenqubo yokukhiqiza yamapayipi ensimbi yensimbi, kanye nokulawulwa kwekhwalithi kanye nezidingo zokuhlola. Ukuhambisana naleli zinga kungaqinisekisa ukusetshenziswa okuthembekile kwamapayipi ensimbi angenamthungo emazingeni okushisa aphezulu nasezindaweni ezinengcindezi ephezulu.
Umkhiqizo othengwe ikhasimende ngalesi sikhathi ipayipi lensimbi le-carbon i-ASTM A106 G.C. Ake ngikubonise imininingwane ethile yesilinganiso kanye nokulawulwa kwekhwalithi yawo wonke umkhiqizo.
