Ditch Witch

Ditch Witch has introduced the MT16 microtrencher. The cost-effective microtrencher creates an ideal trench in a single, quick and efficient pass when working with the Ditch Witch RT55 or RT80 ride-on trenchers, and the FX65 vacuum excavator. Designed to cut narrow trenches 0.5 to 2.0 inches wide and up to 16 inches deep, the MT16 decreases the disruption to surrounding infrastructure during fiber deployments. An integrated hydraulic accumulator maintains constant pressure on the saw frame for sharper-edged cuts and improved spoils removal. In addition, an infinitely variable hydraulic plunge feature eliminates manual adjustment of the microtrencher by providing variable depth control from zero to 16 inches. For a tighter-cut radius, the unit’s frame swings up to six degrees in each direction, enabling operators to efficiently cut on a street corner or around a cul-de-sac. www.ditchwitch.com/trenchers/micro/mt16

Schweitzer Engineering Laboratories

Schweitzer Engineering Laboratories (SEL) released the SEL-T400L Time-Domain Line Protection—the world’s first traveling-wave microprocessor-based relay. It detects power system faults and sends a trip signal to breakers four to 10 times faster than present-day phasor-based relays, offering ultra-high-speed and secure protection of critical transmission lines. Using a combination of traveling-wave and incremental-quantity protection technologies, the SEL-T400L trips as fast as a single millisecond. Faster tripping times mean improved safety, less damage to equipment, improved system stability, and better power quality. With this product, utilities are able to extend the life of existing transmission infrastructure, resulting in significant cost savings. Additionally, Fast Time-Domain Values is like having an oscilloscope on the power system, allowing users to analyze high-speed transient events to understand what happened and take corrective actions. www.selinc.com/p259

Battelle

Battelle offers a solution to predicting when axial cracks can occur in a pipeline. The Columbus, OH research center has released PipeAssess PITM Axial Crack Software designed for oil and gas pipeline companies to meet critical industry requirements and simplify decision-making. The software incorporates important simulation elements such as user-defined hydrostatic tests, operating pressure profiles and attribute inputs (including pipe geometry, material properties and crack geometry) to provide more complete and accurate life prediction, compared to other software solutions. It provides reliable, physics-based modeling and prediction for axial crack growth in standard line pipe sizes and grades, including pipes made of brittle, quasi-brittle and ductile steels. It considers multiple mechanisms for crack growth, including time-dependent cracking during hydrostatic tests and fatigue cracking due to pressure cycles. A demo for PipeAssess PI™ is available for download at www.battelle.org

Metegrity Inc.

Metegrity Pipeline Enterprise is among the most advanced pipeline construction data capture systems on the market and has been deployed by Enbridge on its Norelite Diluent Pipeline project. PE captures the construction stage of new projects, gathering daily data from the field through iPads and Windows-based PCs. It provides up-to-date information on any project worldwide, such as clearing rights-of-way, trenching, staging, welding, LEMS, cleanup and turnover. Non-destructive testing/examination and survey results are also captured. Because it is a relational database app and not PDF or Excel files sitting in SharePoint, customers can quickly identify “bad actors,” and do trending, planning, re-scheduling, business intelligence, etc. on all ongoing pipeline construction projects. www.metegrity.com

Performance Pipe

Performance Pipe, a division of Chevron Phillips Chemical, offers a new polyethylene (PE) pipe with capabilities that improve abrasion resistance in industrial and energy applications such as mining, oil and gas gathering. DriscoPlex® 4800 Series PE pipe is manufactured from high-quality medium-density polyethylene (MDPE) that conforms to ASTM F714 and D3350. Testing has demonstrated that the pipe provides at least 30% greater abrasion resistance, compared to other high-density polyethylene (HDPE) pipes tested, translating to longer service life in these application areas. It is more than four times as resistant to slow crack growth compared to the PE4710 requirement, and offers less stiffness and greater ductility. Combined with reduced weight, this aids in field handing/installation. DriscoPlex® 4800 Series MDPE pipe is available in a full range of sizes, pressure capabilities, molded and fabricated fittings. www.cpchem.com

McElroy

The McElroy Acrobat – a hydraulic butt fusion machine, originally designed for the plumbing and mechanical industry – is available for the underground construction market. Priced competitively, the Acrobat 180 is an easy-to-use machine that butt fuses 63-180mm (2-inch IPS to 6-inch DIPS) HDPE pipe and fittings with several pressure ratings. With its light weight, it can be carried from joint to joint yet maintains rugged reliability. Acrobat 180 is designed for in-ditch work and tie-in fusions, and provides a cost-effective alternative to electrofusion. It functions in tight work spaces by removing the base and converting the carriage from four to three jaws. The top jaws can be removed for easier manipulation around pipe and fittings. Two hydraulic power unit (HPU) options are available to provide fusion pressures up to 800 psi or 1,500 psi. Acrobat 180 is compatible with the DataLogger® for joint reporting and quality assurance. Included is a five-year warranty. www.mcelroy.com
