Concentric Pipe and Tool Rentals’ wrench system speeds up rig time, reduces safety risks

The Superior Safety Wrench System (SSWS) features four wrench-head sizes from 1 in. to 4 in. and provides safety and cost efficiencies. David Wilson, President of Concentric, highlighted the safety improvements of the SSWS at the 2014 OTC on 6 May in Houston.

Concentric Pipe and Tool Rentals has developed the Superior Safety Wrench System (SSWS), a next-generation tool to eliminate the use of sledge hammers in the make up and break out of high pressure, temporary flowline connections.

“This wrench takes away the hammer,” David Wilson, President of Concentric Pipe and Tool Rentals, explained at the 2014 OTC on 6 May in Houston. “We’ve sped up rig time by up to two hours, and it’s efficient and applies to every connection in the world.”

Concentric, a Superior Energy Services company, designed the SSWS for land and offshore operations. The tool is composed of two main parts: a heavy-duty aluminum, wrench-style head and a quick-latch, adjustable torque-assist device. Extensive, external field tests were conducted on 2-in. to 4-in. unions, and the SSWS passed all tests.

The wrench-head adjusts from 1 in. to 4 in., creating an even distribution of impact load on all three union lugs. The wrench head adapts to all disfigured hammer unions. The design of the handle provides a quick-latch feature extending 14 in. to 22 in. in length. Its even distribution of torque allows the union to contact the seal evenly without compressing or compromising the seal.

The SSWS includes significant safety features and provides a cost-efficient alternative to similar tools. Its design eliminates the risks and dangers of sledgehammer use, such as injuries from swinging sledgehammers with poor form, holding a target while it is hammered, releasing sledgehammers midswing and fragmenting because of a worn out sledgehammer or target. Because of the efficiency of the system, the wrench can also reduce rig-up and testing time.

“Our goal is to eliminate on-the-job injuries associated with projects that utilize tools like the Superior Safety Wrench System, because nothing is more valuable than the safety of our customers and our employees,” said Mr Wilson.

The SSWS is currently available to rent as a manual tool. A pneumatic version will be available later in 2014 and customization is also available.
