The Above said QAP is our internal procedure of testing. We provide our internal inspection report to our customers.

Based on internal inspection report we allow our customer to check following :

  1. Physical verification of valves & quality check.
  2. Witnessing a leakage test i.e. hydro test as per our standard test procedure & pressure rating confirmed by us only for acceptance sampling i.e. 10% of the total quantity.
  3. Chemical resistance of ISOTACTIC PP is more than that of normal grade PP even at an elevated temperature.
  4. Dimension check of final assembly of valve as per our standard drawings.
