Liroboiti tsa tšepe tsa tšepe ha e le hantle li tsamaisa peōpe ea tšepe, e leng moelelo oa tšepe le feela motheo oa tšepe, ka lebaka la lebitso la bona. Graphite ho Ducing Iron Pipes e teng ka sebopeho sa Spilail, e nang le boholo ba limaraka tse 6-7. In terms of quality, the spheroidization level of cast iron pipes is required to be controlled at 1-3 levels, with a spheroidization rate of ≥ 80%. Ka hona, thepa ea mochini oa thepa eo ka boeona e ntlafalitsoe, e na le moelelo oa tšepe le thepa ea tšepe. After annealing, the microstructure of ductile iron pipes is ferrite with a small amount of pearlite, which has good mechanical properties, hence it is also called cast iron steel pipes.
