7 pg. 8 / Vallourec USA Corporation / Premium Vallourec USA Corporation / Premium / pg. 9 VAM USA Connection Technology Center: A comprehensive range of e quipment Threaded & Coupled The quest to find and recover new oil and gas reserves has never been more challenging. As these well conditions become more hostile, VAM is ever more committed to designing connections suited for a variety of conditions including: Elevated Temperature Extreme Temperature fluctuations (Steam Injection or SAGD) High Pressure / High Temperature (HPHT) Sour Service Extreme Frac Pressures High Torque Fatigue Loading Severe Dog legs Your Challenge - Our Commitment VAM Premium are used in the most hostile environments and applications. Operator safety, well life, return on investment (onshore and offshore) rely on the quality of our products. Therefore, the performance of all VAM connections are validated through full scale psychical testing at one of our three R&D centers to fully respond to those requirements. Sample Preparation A critical component for the development and validation of new products is sample preparation. VAM USA has incorporated the latest FEA equipment, CNC lathes and gauges within the testing facility to produce test specimens to the highest tolerances representing the worst case scenarios in the field. Make and Break VAM USA can perform make up and break out simulations that validate the seal sensitivity and galling sensitivity of VAM premium connections under critical conditions. VAM USA also uses the tongs to evaluate the dope sensitivity of VAM premium connections to new formulas of thread compound required by our customers including environmental friendly green dope or CLEANWELL. Combined Loads (tension & compression with internal & external pressure) The VAM USA load f rames have a maximum tension capacity of 6 million pound force and a maximum compression capacity of 5.2 million pound force. VAM USA has the ability to simulate combined loads (tension or compression) under high internal pressure (30,000 psi using gas and 35,000 psi using water) or external pressure (35,000 psi). Bending VAM USA has testing equipment that can simulate combined loads with bending (up to 70 degrees per 100ft). Elevated Temperature VAM USA can perform all simulations at ambient or elevated temperature (up to 600 F) including thermal cycles (ambient to elevated temperature). Fatigue Life VAM USA can perform fatigue tests that are required to assess the fatigue life of any VAM premium connection (high stresses / low cycles or low stresses / high cycles). These extensive testing standards provide assurance to our North American customers that our premium connections have been physically tested beyond their stated capabilities and secure VAM as the premier premium connection provider worldwide.
