What an honor to be able to attend the Ameren 2017 Supplier Diversity Symposium at the Four Seasons in St.Louis Missouri last week.  With Networking events and Workshops such as; “Doing Business with Ameren” headed by 5 panelists from Ameren, and “Leveraging Tier 2 – Strategies for Doing Business with Ameren” with speaker Kevin Settle from J.F. Electric, it was an informative event.  Made even more special with celebrated speaker Clifton Taulbert; pulitzer nominated author, entrepreneur and businessman whose inspirational speech was a highlight of the program.

Thank you Ameren for your attention and dedication to helping the Diverse Suppliers of America!

Recently, there has been some bad press with regards to the use of expandable tube plugs in the Power Plant Industry.  So bad actually that Plants are opting to pay out 10 times as much, for a tube plug that is perfect for  high pressure applications but OVERKILL for low pressure, low temperature heat exchangers and condensers.

Most of the bad press is due to failures seen with the black neoprene rubber type expandable plugs.  These are plugs made with the black rubber seals along with inexpensive spacers.  For some jobs, these plugs may work just fine, especially short term because the cost is low.

The cost is on par with the price of the pound in/”driven” plugs, either the two pin or a single tapered brass pin.  These types of plugs, while they will do the job, have two disadvantages over their expandable counter parts.
One is the fact that as soon as you pound in any plug into a tube, you have already created a scenario where; the tube has now expanded from it’s original shape, has potentially created cracks in the tube sheet and if the tube was taken out of service for flow reasons or scheduled to be tested at a later date, will need to be drilled out of the tube.  That will cost the Plant downtime and money and still you are left with tubes that have been permanently damaged.

The plug market is a niche market and one that often gets ignored until there is a significant problem with the Plants condensers/heat exchangers.  Best to be armed with the FACTS.

Here are the FACTS:

  • There are only a few types of plugs; Pound in/”Driven” pins, Expandables, and Mechanical/Explosives.
  • Pound in/Driven and mechanical/explosive plugs cause damage to tubes/tube sheets and if need to be removed will cost money and downtime.
  • Black rubber seal expandable plugs will crack, break down and lose their seal due to heat and cycling overtime.


  • Silicone expandable plugs will never break down, will last indefinitely, will NOT cause damage to tubes/tubesheet and will NOT have to be drilled out to be removed.


While the silicone expandable tube plugs cost a bit more in the short term due to preferable materials, such as non-water soluble washers and collars in conjunction with high temp silicone. You get what you pay for with our Hepco tube plugs. Our expandable plugs will not only LAST in the long term but COST less in the long term as they won’t cause any damage to your condensers and will seal indefinitely.

So the bottom line is this; when you have condensers and heat exchangers that don’t need a high pressure/high temp application, the BEST solution for plugging these tubes is HEPCO expandable silicone tube plugs.

Oklahoma’s oil and natural gas boom is fueling growth in another energy sector — electricity.Central Rural Electric Cooperative recently received a $9.7 million Rural Utility Service loan from the Department of Agriculture. CREC will use the money to upgrade lines, smart meters and other infrastructure, the cooperative’s Chief Executive Officer David Swank said.

“CREC is fortunate that we’re seeing growth throughout our service area,” Swank said. “The recent increase in oil and gas production in the area has created a steady boost to our economy. Businesses are busier, houses are being built and CREC is working hard to meet this new demand.”

The Stillwater-based electricity cooperative is working with more than 250 oil and gas producers throughout its service area which covers 2,000 square miles and includes parts of Noble, Garfield, Lincoln, Logan, Oklahoma, Pawnee and Payne counties. Much of the growth is on the western half of the CREC system, CREC Communication’s Coordinator Larry Mattox said.

“We serve all the way down to Stroud and east of Cushing, but most of it (growth) is happening near Mulhall-Orlando on west side of our system,” Mattox said.

The cooperative already has responded to that growth using its utility crews and contractors to upgrade the system, Mattox said. The federal loan will spur the process forward.

The federal loan is commonplace for cooperative and the capital-intensive rural utility industry.

CREC was founded and began operating with a $130,000 Rural Electrif-fication Administration loan in 1937. Over the years, federal loans from the REA, which evolved into the Rural Utility Service, have helped CREC keep up with growth. The cooperative has assets in excess of $110 million and employs approximately 80 people, according to information on the CREC website.



Thank you to everyone that visited us at the EPRI Condenser Technology Conference in Chicago, IL this past week of Aug. 3rd and 4th. A lot of good information was shared with regards to improving condenser performance and tackling some of the various problems associated with cleaning and maintaining the condensers.

For our part, we look forward to providing you with the best performing and versatile condenser tube plugs in the Industry. One that can be used to seal a tube permanently or temporarily given your specific criteria and also, one that will not cause any further damage to tubes or tube sheets. Read more

After overseeing the daily operations of Heat Exchanger Products Corporation (HEPCO) for the last seventeen years, Tracy Hennigan Bonnyman has finally decided to purchase HEPCO making it officially a Woman Owned and Operated Business.

Hepco is currently in the process of acquiring it’s Certification for being Woman Owned in order to be able to be included in the Industries Diversified Vendor Data Base. “We manufacture a very reliable product and I believe this will be a great benefit for our clients to be able to access us within this data base.” Bonnyman stated recently.

While it’s a well known fact that titanium is a more expensive material than say stainless steel or copper-nickel alloys, when given the facts about corrosion resistance, titanium comes out ahead.

The reason titanium is an overall better tubing option than some materials is due to it’s immunity to corrosion. It is impervious to corrosion in saline and brackish environments and since titanium produces a naturally occurring oxide film, it resist breakdown from chloride ions as well. It is also resistant to biofouling. Read more

By using the newest technologies in silicone rubber, Hepco proves their dedication to providing their clients with high-performance, cost effective, condenser tube plugs. Silicone rubber is the material of choice over black rubber and metal for low pressure condenser and heat exchanger tube plugs.

There are several reasons why Hepco recognizes silicon rubber as a superior material for their condenser tube plugs. At the top of their list is its superior performance when it comes to flexibility and heat resistance. Read more
