These Vogt-Nem OEM Penetration Seal Expansion Joints we’re exposed to a temperature excursion beyond their intended max when the false floor in the HRSG collapsed. You can see that the metal has started to anneal, which means it could fail at that point and cause a safety hazard. This is a good application for INTEREP’s Interflex bellows insulation system, which will allow the unit to run until the next outage with no safety concerns if a failure should occur.

These guys just finished installing 60 penetration seals (a full Alstom HRSG) which replaced the OEM “Korema Kompensatorenwerk” silicone & fiberglass expansion joints. All of the welded flange-studs on the front module (HPSH) had corroded and rusted, many had broken off. It was a gnarly job crawling around beneath the structural steel and welding them back together, but Steam Generation Corp was up to the task, and they’ve got the bruises to show it!

We reverse-engineered this 6″ Metal Bellows Expansion Joint with 304 stainless flanges to match an old customer specification that was no longer available from the original manufacturer. Check out the welds on those little shipping bars!

What happens when you heat liquid carbon dioxide? #Cardox – high-pressure gas (>40,000psi) Cement plants use it to clear plugged preheater tower meal-pipes. This metal bellows was too close to a Cardox charge (top left) which destroyed the refractory meal-pipe lining & damaged the expansion joint. The refractory was repaired with Blu Ram (phos-bonded mullite) and we manufactured a new bolt-in metal bellows expansion joint which slides into the meal-pipe (bottom left & right).

These Proco Products Penetration Seals were just installed in the chemical & sludge wet wells at a combined cycle power plant. They can be unchained, wrapped around the pipe, slid into place, and then expanded to create a watertight seal. Excellent for retrofit applications.

If you look closely at the restraining hardware (tie-rods) on these expansion joints, you’ll see there are no outboard nuts. That means these EJs are exerting their full pressure thrust upon the adjacent piping. Apparently the elbows below them are handling it well, as they’ve been installed for 15 years.

This universal expansion joint got put on the high pressure bleed air line of a gas turbine, deforming the metal bellows. It was made for the low pressure bleed air. Check with us first and we’ll help you avoid rush orders and emergency repairs.
