The material of our products are KTH , the national standard of Material grade need to arrive to KTH300-06 , the standard of our products is KTH330-08 . the KTH stand for Black heart malleable cast iron , the 300 , 330 , 350 is for extending and 06,08,12 is for stretching. All this is stand for toughness .
Angular deviations :
National standards allow for a range of angular deviations, but this deviation is within the range of plus or minus 0.5 °.
Size standard :
Our products are fit to the national standard .
Weight standard:
Until now , there is no weight standard to the pipe fitting .
