Umgangatho we-A106 ubhekisa kwiI-ASTM A106/A106Mumgangatho, ongumgangatho wemveliso wemibhobho ye-carbon steel engenamthungo ekhutshwe yi-American Society for Testing and Materials (ASTM International). Lo mgangatho uchaza iimfuno zokusetyenziswa kwemibhobho ye-carbon steel engenamthungo phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.
Umgangatho we-A106 usebenza kwiindawo zenkonzo yobushushu obuphezulu kumashishini ngokubanzi, njengokucokisa i-petroleum, ishishini lemichiza, izikhululo zamandla, iibhoyila, ukufudumeza kunye nemibhobho yoxinzelelo oluphezulu kunye nezinye iinkalo. Iquka amabakala amaninzi ombhobho wentsimbi yekhabhoni, kubandakanywa amabakala A, B, kunye noC.
Ngokomgangatho we-A106, imibhobho ye-carbon steel engenamthungo kufuneka ibe neekhemikhali ezithile kunye neempawu zomatshini. Iimfuno zokubunjwa kweekhemikhali ikakhulu ziquka umxholo wekhabhoni, umxholo we-manganese, umxholo we-phosphorus, umxholo wesulfure kunye nomxholo wobhedu. Iimfuno zepropathi zoomatshini ziquka ukomelela, ukomelela kwesivuno, kunye nobude, phakathi kwezinye. Ukongezelela, ubungakanani, ubunzima kunye nokuphambuka okuvumelekileyo kwemibhobho kucacisiwe.
Umgangatho we-A106 ufuna ukuba imibhobho yentsimbi ye-carbon engenamthungo kufuneka ikwazi ukumelana noxinzelelo phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, kwaye ibe nokumelana nokugqwesa kwe-corrosion kunye nokumelana nokuqhekeka kwe-hydrogen. Inkqubo yokuvelisa kwayo ibandakanya umzobo obandayo, ukuqengqeleka okubandayo, ukutshisa okutshisayo okanye ukwandiswa kwe-thermal, njl., Ukuqinisekisa ukuba indawo yangaphakathi nangaphandle yombhobho ilula kwaye ayinaziphene.
Ngokwamalungiselelo omgangatho we-A106, imibhobho yentsimbi yekhabhoni engenamthungo kufuneka ihlolwe kunye novavanyo olunjengohlalutyo lweekhemikhali, uvavanyo lokusebenza koomatshini, uhlolo olubonakalayo, ubungakanani bodonga, uvavanyo loxinzelelo kunye nokuhlolwa okungonakalisi ukuqinisekisa ukuba umgangatho wabo udibana iimfuno ezisemgangathweni.
Ukuqukumbela, umgangatho we-A106 ngumgangatho obalulekileyo wemveliso yombhobho we-carbon steel, ochaza ukubunjwa kweekhemikhali, iipropati zomatshini kunye neemfuno zenkqubo yokuvelisa imibhobho ye-carbon steel, kunye nokulawula umgangatho kunye neemfuno zokuhlola. Ukuthotyelwa kwalo mgangatho kunokuqinisekisa ukusetyenziswa okuthembekileyo kwemibhobho ye-carbon steel engenamthungo kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu.
Imveliso ethengwe ngumthengi ngeli xesha ngumbhobho we-carbon steel we-ASTM A106 G.C. Makhe ndikubonise iinkcukacha ezithile zomlinganiselo kunye nolawulo lomgangatho wemveliso yonke.
