1, ukuhlolwa kokwakheka kwamakhemikhali

1. ngokwesakhiwo samakhemikhali kanye nezakhiwo zemishini zamapayipi angenamthungo asekhaya, njenge-10, 15, 20, 25, 30, 35, 40, 45 kanye ne-50 ukwakheka kwamakhemikhali ensimbi kufanele kuhambisane nemibandela ye-GB/T699-88. Amapayipi angenamthungo angenisiwe kufanele ahlolwe ngokwezindinganiso ezifanele ezichazwe enkontilekeni. Ukwakheka kwamakhemikhali ensimbi ye-09MnV, 16Mn, 15MNV kufanele kuhambisane nemibandela ye-GB1591-79.

2. Bheka ku-gb223-84 “Izindlela Zokuhlaziya Amakhemikhali Ensimbi Ne-Alloy” ukuze uthole izindlela ezithile zokuhlaziya.

3. ukuhlaziywa kokuphambuka ngokusho kwe-GB222-84 “ukuhlaziywa kwamakhemikhali ensimbi ngamasampula kanye nokuphambuka kokwakheka kwamakhemikhali komkhiqizo oqediwe”.

2, ukuhlolwa kokusebenza ngokomzimba

1. ngokwendlela esebenza ngayo ukuphakelwa kwamapayipi angaphakathi angenamthungo, insimbi yekhabhoni evamile ngokwesigaba se-GB/T700-88 sokukhiqiza insimbi (kodwa kumele iqinisekise ukuthi okuqukethwe kwesalfure akudluli ku-0.050% kanye nokuqukethwe kwe-phosphorus akudluli ku-0.045%), izakhiwo zayo zemishini kufanele zihlangabezane nenani elichazwe kuthebula le-GB8162-87.

2. Ngokusho kokuhlolwa komfutho wamanzi, ukuhlinzekwa kwepayipi elingenalutho lasekhaya kumele kuqinisekiswe ukuthi izinga lokuhlolwa komfutho wamanzi lisezingeni elifanele.

3. Ukuhlolwa kokusebenza ngokomzimba kwepayipi elingenayo i-seamless kumele kwenziwe ngokwezindinganiso ezifanele ezichazwe kwinkontileka.
