New Enerpac MITT Series Mechanical Isolation & Test Tools Cut Downtime for Oil and Gas Pipe Welding

The new Enerpac MITT series provides a safe and efficient method for inline pipe isolation and localised pressure testing of new welds during oil and gas pipe maintenance. By eliminating the need for traditional chemical cleaning and system hydrotesting, the MITT series tools streamline the implementation and testing of pipe modifications, significantly reducing plant downtime.

The traditional method of oil and gas pipe modification involves extensive flushing, chemical cleaning and drying followed by time-consuming filling, pressurising and hydrotesting of full pipe runs to protect against flammable vapours when welding onto pipe. The MITT tools make traditional chemical cleaning and system hydrotesting methods for piping modifications obsolete.

No More Pipe Cleaning and Steaming

Inline tools like the Enerpac MITT series create a positive seal against the inside of a pipe for vapour-barriers during hot work and/or for pressure testing new welds during maintenance operations. Cleaning and steaming can be eliminated since pipes do not have to be completely gas free. Inline tools provide sealing capability with the ability to monitor throughout hot work activities via hydrostatic pressure. They also provide venting capabilities with the ability to monitor upstream pressure build up.

When it comes to localised weld testing, inline tools reduce system downtime and increase worksite safety by minimising test medium volume. In addition, they save time and reduce costs by limiting the test area to only the new weld or welded component.

The new MITT series tools are the lightest weight tools on the market with higher test pressure capacity than any other mechanically actuated tools. The low profile, durable, aluminium construction allows one operator to lift, isolate and test behind elbows and tees with standard off-the-shelf tools. The MITT series tools are dual-purpose (isolation and hydrotest) tools that outperform other inline tools with more pipe schedules covered per tool, inexpensive seals and seal backing rings.
