API 5CT

Q125

API grade for deep well service, not generally for use in sour condensate wells. Quadrant hardness testing is required without any specified limits other than the variation between readings. Impact testing is required for each head and/or lot. NDT inspection is required with two methods of inspection (typically EMI and UT are performed on this product).
