Please be hereby informed that on December 10, 2008, the Pipeline Operation Department once again conducted field tests of SMART LOCK at the interfield pipeline "SU-5 – UPSV Kozlovskaya tie-in connection (Devonian) – UKPN-1" with diameter of 273 mm, upon leak at Stake 1+00 to eliminate a penetrating defect at operating pressure of 2.0 MPa. The test results: recovery of the pipeline pressurization at the penetrating defect without ceasing pumping of liquid. SMART LOCK remains under visual monitoring.
The use of SMART LOCK allows us to eliminate a critical issue of a prompt repair of penetrating defects of the oilfield pipelines without ceasing of pumping and discharging and without any claims from the federal authorities regulating such types of repairs.
In view of the foregoing, I kindly ask you to submit a quotation for SMART LOCK, diameter 273 mm. The need of OAO "Samaraneftegaz" is about 20 repair couplings per moth, totally 240 pieces per year.
Please submit information on or before December 22, 2008 to the Pipeline Operation Department of OAO "Samaraneftegaz" to the address and details available.
With kind regads,
|Deputy Chief Engineer – Head of the Pipeline Operation Department
