1, ukuhlolwa kokwakheka kwamakhemikhali
1.ngokokwakheka kwamakhemikhali kanye nezakhiwo zemishini zamapayipi asekhaya angenamthungo, afana no-10, 15, 20, 25, 30, 35, 40, 45 kanye nokwakheka kwamakhemikhali ensimbi angama-50 kufanele kuhambisane nezinhlinzeko ze-GB/T699-88. amapayipi angenamthungo azohlolwa ngokuvumelana nezindinganiso ezifanele ezibalulwe kwinkontileka.Ukwakheka kwamakhemikhali kwensimbi engu-09MnV, 16Mn, 15MNV kufanele kuhambisane nezinhlinzeko ze-GB1591-79.
2. Bheka ku-gb223-84 “Izindlela Zokuhlaziya Amakhemikhali Ensimbi Nengxubevange” ukuze uthole izindlela ezithile zokuhlaziya.
3. ukuhlaziywa kokuchezuka ngokuya nge-GB222-84 “ukuhlaziywa kwamakhemikhali ensimbi ngamasampula kanye nokuchezuka kokwakheka kwamakhemikhali omkhiqizo oqediwe”.
2, ukuhlolwa kokusebenza komzimba
1.ngokokusebenza kokuhlinzekwa kwepayipi elingenamthungo lasekhaya, i-carbon steel evamile ngokusho kwe-GB/T700-88 class A steel production (kodwa kufanele kuqinisekiswe ukuthi okuqukethwe kwesibabule akudluli i-0.050% futhi okuqukethwe kwe-phosphorus akudluli 0.045%), izakhiwo zayo zomshini kufanele zihlangabezane nenani elishiwo kuthebula le-GB8162-87.
2.ngokuhambisana nokuhlolwa komfutho wamanzi wepayipi elingenamthungo lasekhaya kumele liqinisekise izinga lokuhlolwa komfutho wamanzi.
3. Ukuhlolwa kokusebenza komzimba kwepayipi elingenamthungo elingenisiwe kuzokwenziwa ngokuya ngamazinga afanele abalulwe kwinkontileka.
