combating Falsified ductile iron pipe

[aladili1]

Hi there ,
Do any one have any document which help me to recognise the ductile iron pipes manufactured from XINXING or STF or any other manufacturers in the world . I hope some one will help me because we are in Iraq suffering from a big quantity of falsified ductil iron pipes. Thanks.

Most ductile iron pipe has the country of origin stamped into the casting.
