The MTD series is a range of MOEDINGEN two-stage hydraulic bolt tensioners with automatic piston return, designed to tighten and loosen large-diameter bolted joints accurately and efficiently. The two-stage cylinder design minimises the outside diameter of the tensioner so it can fit into the tight space between the nut and the flange. A high-strength alloy-steel body with a black-oxide finish resists corrosion, and the automatic piston return together with a low-friction seal speeds up every bolting cycle. The series is intended for use on common ANSI and API flanges as well as on heavy-duty maintenance jobs in oil and gas, petrochemical, power and marine applications.

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.
