Tri Tool offers a wide range of equipment solutions and services to support the protection and efficient operation of pipelines. Our team of experts is very experienced in pipeline maintenance and understands the sensitive nature of working with in-service pipelines. We have developed special procedures to perform linear casing cuts and our clamshells are engineered to handle any pipe size or material.
Various failures can occur in welds during construction or maintenance of critical piping systems, prompting the removal or “excavation” of the filler weld material. In addition, weld excavations are a great alternative in a weld repair process, as no length of pipe is lost. However, the challenge is to precisely machine away all of the weld material without disturbing the parent pipe material and ending with a well finished surface for the new weld. With Tri Tool’s state-of-the-art portable machining equipment, our Field Services team can excavate the weld down to the depth of the indications and stay within the weld material to not violate the parent pipe material, saving you time and money in your weld repair project.
As a leading provider of industrial pipe cutting and beveling clamshell products and services, Tri Tool can take on any task or problem and develop start to finish solutions. Our Elliptical Manway Machine is intended for restoring an elliptical gasket sealing surface and can be operated from inside or outside the manway. The portable machine easily allows for the repair of manway sealing surfaces by removing any steam checks, and manways can be machined true and accurate without grinding.
To meet the demand for deep counterbore machining of steel catenary risers and critical pipeline construction needs, Tri Tool has designed and manufactured a high-speed counterboring system that eliminates the guesswork on high/low discrepancies and delivers a perfect fit up every time. From a single 6” pipe to a limitless larger bore, the portable high-speed deep counterbore system delivers deep counterbore precision, rapid cycle times, and superior surface finishes. You get a concentric bore quickly and efficiently.
Safety is optimized in this system with incoming and outgoing mechanized pipe handling racks that require no manual pipe handling. Cycle times are optimized with laser-assisted pipe end alignment and rapid machining by dual, seven axis CNC machines equipped with real-time monitoring and the latest safety features. Our Field Services team is trained on manual and CNC equipment to provide you with the most effective solution for your specific project.

Field Services Case Study
Faced with an emergent need to replace a reactor coolant system primary check valve at the Sequoyah Nuclear Plant, the Tennessee Valley Authority turns to Tri Tool to deliver quality on an expedited time frame.
During a routine outage at the Sequoyah Nuclear Plant a nuclear power plant owned by the Tennessee Valley Authority (TVA) that generates enough power for 1.3 million homes each day plant personnel unexpectedly found that a Reactor Coolant System (RCS) primary check valve needed to be replaced. However, the valve was located in a very congested area that required special considerations due to various radiological conditions.
Find out how Tri Tool mobilized a crew of pipefitters, machinists, and welders within 24 hours to execute a "like-for-like" replacement of the valve with zero safety or performance issues.
