SRT Spring-Return Bolt Tensioner

The SRT series is a range of MOEDINGEN hydraulic bolt tensioners engineered to tighten and loosen large-diameter bolted joints accurately and evenly. Each model is interchangeable with the common ANSI and API flange standards, so it can be used directly on a wide range of piping, flange and vessel connections. The tensioners are light and easy to carry, have a non-slip surface for safe handling, and are protected with a nickel-plated finish that extends service life. A reinforced oil seal design improves reliability, and the units are built for simple, low-cost maintenance.

Optional Attachment

The MDW square drive hydraulic torque wrench range spans 112 to 72,000 N·m in 11 standard models, with bolt capacity from M14 to M125. A single tool family covers light flange work through heavy structural bolting, so your crew standardizes on one platform with common pumps, hoses and high-strength sockets instead of mixing tools from different suppliers
