The specific product is a nominal API 7"-5000#, and is modular in the sense that it is adaptable from a 4" thru a 6" nominal flow bore by replacing only a handful of parts, which makes it unique. To date (04/09) the maximum size product (any manufacturer) suitable for the Secure Drill system has been 3". Expro’s client, Trans Ocean, has conducted extensive System Integration Testing in their manifold, and is quite pleased with the product. The operating service provides high flow characteristics for severe corrosive service applications.
