The Sole purpose of Duct integration testing is to prove that the installed ducts or pipes are ready for blowing of the product and that the ducts are through without any hindrance from One Manhole to other.

The duct integration test is carried out with the help of Compressed air and a suitable go-gauge mandrel of appropriate size, which is thrusted inside with pneumatic pressure and is thrown outside from the other end.

If the mandrel passes out smoothly the duct is considered ready for cable blowing.
