Collector Ring Machining

We recently finished a Collector Ring Machining project for a power generating unit on the East Coast.  As outages get closer to finishing we see an influx of Collector Ring and Journal Machining requests come in.   If you have any Collector Ring Machining needs please contact us today!   For our latest Collector Ring Machining brochure, CLICK HERE.

April Safety Update

We’ve completed the month of April with zero OSHA-recordable injuries and have a TRIR of 0.00 for the year. We continue to be proactive in identifying potential hazards and maintaining our safety-first mindset. Great job by our HSE Director, Shannon Scruggs, our Repair Facility Management and Technicians, and each one of our Field Service Project Management teams for engraining our safety culture throughout the organization. Nice job everybody!

Gas Nitriding of Turbine Components

One of the durability enhancements we offer for turbine components is gas nitriding.  Gas nitriding is a surface hardening process, where nitrogen is added to the surface of steel parts using dissociated ammonia as the source. Gas nitriding develops a very hard case in a component at relatively low temperature, without the need for quenching. As a result, a very high strength product with extremely good wear resistance can be produced, with little or no dimensional change. For valve components, these material enhancements translate into increased durability and service life and ultimately, reduced maintenance cost.

Gas nitriding can be a time consuming process, which is why we have the equipment in-house to ensure you receive the quickest turnaround times possible during your turbine outage.  If you want to learn more about this and other durability improvements we offer please visit our part manufacturing web page HERE.

 

Core Values

As we continue through this busy spring turbine outage season completing projects for customers across the globe, it is important to take a moment to reflect upon our Core Values.   We strive to perform safe, quality work – and act with honesty and integrity – as we attempt to exceed customer expectations.  Our team members are amazing individuals, and it is because of their desire to live by these guiding principles that make us successful as an organization.   We have an excellent team, and consider our customers part of that team.   We enter each turbine project with the same mindset, and the same desire to accomplish the objectives of our customers.  Let’s continue to do amazing things and finish this turbine outage season strong.  Stay safe everyone!

  •  Safety – PSG’s top priority, demonstrated by our excellent track record.
    • Zero Recordable Injuries in 2020 (TRIR is 0.00)

Balance Chamber Repair vs. Replace

Save time and money by repairing your balance chamber instead of replacing it.   You no longer need to worry about the hassle of stocking a spare balance chamber, or be surprised by the lead time when you go to order a new one.  We have been repairing balance chambers for utilities across the U.S. for almost 8 years now with great results.   The next time you discuss the future of your balance chamber please contact us to discuss how we can repair your existing component rather than spending the money to purchase a new one.

Excellent Customer Feedback

We recently received excellent feedback from one of our recent Steam Turbine Major Inspections performed for a Utility customer in the Southern U.S.  This is the type of feedback that makes all of the effort during the planning and execution phases worthwhile.   We are very appreciative of every opportunity we receive, and strive to do our best for each and every customer.  Great to see this type of feedback, and another outstanding job by our field and repair teams!

 

“The response to our RFP was clear, concise, and with a very detailed schedule.”

“It is clear to anyone watching your crew work that PSG has a strong safety culture.”

“The Technical Field Advisor and his team kept us updated and there were no surprises.”

“Of the bids we reviewed for this job, PSG had the most aggressive schedule and then met that schedule. This was a planned 60 day outage that was shortened to 45, so meeting the planned restart date was critical.”

“No leak, no issues, no defects. Very impressive.”

“Very detailed outage report. Better than I am accustomed to seeing.”

“The proposal for the inspection was detailed and thorough. Likewise for all extra work generating during the outage.”

“Documentation was accurate and detailed.”

“I would be glad to have PSG here for our next outage.”
