BuTech API 17D - Drilling Deeper With Confidence
BuTech’s high performance, high-pressure subsea valves and fittings make it possible.
BuTech’s high-performance, high-pressure subsea valves, and fittings make it possible. Design engineers at BuTech know that exploration in deep water requires robust, highly engineered, corrosion-resistant equipment capable of operating reliably at extreme pressures and temperatures for 30 years. In a tight regulatory landscape, it is paramount that drilling deeper and extracting reservoirs for long periods be accomplished safely. This puts incredible demands on every piece of subsea equipment, large or small.
Subsea valves and fittings dutifully perform in substantially inaccessible places where repairs are practically impossible, that is why it’s important they are reliable. Despite their physical size, subsea valves are installed in some of the oil and gas industry’s most challenging applications. On the ocean floor, subsea valves are installed on manifolds and X-trees where, to ensure the success of wells 10,000 feet (3,048m) deep, valves and fittings must withstand pressures reaching 20,000 psi (1,378 bar), without sacrificing safety, reliability, or performance.
Ball and needle valve specifications
Ball valves and needle valves used subsea must provide performance, safety, and long service life.
BuTech quarter turn, trunnion-type ball valves with spring-loaded seats offer the highest reliability, bubble-tight seals, and nearly unlimited end connection possibilities. Our double barrier subsea ball valves also feature redundant seals to prevent injection chemicals from reaching the environment.
Subsea needle, block-and-bleed, and double block-and-bleed needle valves provide the advantage of metal-to-metal seats, non-rising stems to prevent galling and stem packing below the threads to reduce the risk of fouling.
Customization is Key
No application is the same and no product perfectly fits into every application. BuTech uses common components when possible to create custom solutions for each Customer’s diverse requirements.
Most features can be customized to address project needs—from the base materials of construction to the flow configuration (2 or 3-way), to the paddle or handle type to the bucket or panel mounts. BuTech is also producing valves and fittings that meet restrictive NORSOK material standards.
BuTech sub-sea valves meet the latest requirements of API 6A, 17D. BuTech valves and fittings are used in the subsea industry across the world and are manufactured to meet standards that vary from country to country, helping its clients maintain compliance wherever they operate. Subsea valves are internally pressure tested to at least 50 percent overrated pressure and externally sealed for depths up to 14,000 feet (4,200 meters), with a typical service life of 30 years. Currently, all BuTech sub-sea valves can handle chemical injection pressures from 10,000 psi to 15,000 psi, with new products being offered or developed for 20,000 psi applications.
