Generate Accurate & High Loads for all Flanges Designed specifically for all Oil & Gas applications. The TRT tensioners fit all standard API, ANSI B16.5 & Compact flanges. Special Series concepts for all B7, L7 & B16 studs bolts. Designed with the aid of Solidworks® and Cosmos® for FEA Light-weight, compact and versatile line of tensioners. Safety First: Overpressure and Overstroke full protection. Spring Return Piston reduces operator fatigue & shrinks operation time. Operates at a maximum pressure of 21,750 psi / 1500 bar. Dual port design allows two time faster operation than single port tensioners. Environmentally friendly: Can be pressurized with Rapid-Torc Water Mix (ISO14000). High strength AISI 4340 steel components for long lasting performanc. Dual Port Design simplifies hose connection and eliminates Tee-block. Visible Piston Stroke indicator for all models. Time saver: All models are able to stroke 15mm. Floating piston for small alignment compensation. Bolt coverage from 1” to 3 ½” with just three tools. Interchangeable adapter kits available for both Metric and Imperial sizes. Anti-slip tool surface improves operator grip and increases safety. Socket design allows tensioners to fit all upside down applications. TRT series is adaptable in a minute when washers. All exterior surface are knurled to allow for easy handling. Larger sizes includes eye bolts for additional support. Option: Ultrasonic measurement system also available .
