Safety Tip! If you see rust or discoloration on the outside of your vent silencer, check the inside. The perforated plate on this one came loose and it began shedding its internal insulation – causing safety and noise issues.

Sometimes you’ve just gotta suit up and get dirty to get plant back online. Here’s our founder, Carl Horecky, field-fitting a high temperature expansion joint belt onto the primary air duct coming off of a coal mill. Once he finishes, a whole coal-fired unit will be back up and running.

When somebody decides to replace a failed expansion joint with an unlike expansion joint laying in the boneyard, things will eventually go wrong. INTEREP was able to right this wrong by redesigning a new metal bellows and spring support to allow for many more years of worry-free operation. Call us if you’re ever in a sticky situation – we’ll bail you out.

An oil refinery had blown out their bellows by hydro testing their sulfur unit at pressures that exceeded what the system was designed to handle. INTEREP upgraded the poorly designed expansion joint to a much sturdier, lasting design, and this was the end result. INTEREP designs for longevity and serviceability. Give us a call and we’ll deliver Peace of Mind to your operations.

Installing Expansion joints against pipe with stub ends and metal rings that back up against our rubber flange causes problems with sealing. The best system with pipe like this is to add an HDPE Flange Ring that lays against the stub end and then attach the rubber flange to the full face HDPE flange.

This reverse air baghouse expansion joint was made of EPDM operating at above 400F, the EPDM got brittle and ended up adhering itself to the duct and cracking across the bottom – filling the penthouse with SO2 gas. Our team retrofitted the expansion joint with one made of PTFE (Teflon) that could handle the temperature. Reverse air ducts can be hard on equipment because they switch from positive to negative pressure, so you want an expansion joint belt with no excess width in it, or it will get sucked into the duct during pressure changes and wear the edges of the belt out.

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!
