Heavy-Duty Piping Components
Our engineering team designs and manufactures high-pressure expansion joints, transition flanges, and reinforced elastomeric seals for demanding process environments. Every component is built to contain highly corrosive fluids under extreme thermal and pressure cycling.
View engineering specsRated for 600 psi at 450°F, the Series 4000 handles aggressive thermal expansion in caustic environments. Multiple-ply stainless steel bellows and reinforced elastomeric seals ensure total volumetric containment. Hydrostatically tested to 1.5 times rated pressure and certified for ASME B31.3 compliance.
Eliminates thermal stress failures in chemical processing linesBimetallic transition flange prevents galvanic corrosion between carbon steel and stainless steel lines. Precision-forged interface with a nickel-alloy barrier layer electrically isolates the two metals. Machined to 32-microinch finish for reliable gasket seating, drilled to ANSI B16.5 class 150 dimensions.
Extends pipeline service life by eliminating galvanic corrosionZero-leak performance for volatile organic compound service. PTFE outer envelope bonded to a fluoroelastomer (FKM) inner core delivers broad chemical resistance and sustained sealing force. Reinforced with a 304 stainless steel insert ring to prevent extrusion under high pressure. Meets EPA Method 21 leak detection standards.
Meets fugitive emission regulations for hazardous air pollutantsWe produce custom flanges for non-standard pipe sizes and pressure classes. Each flange is machined from 316L stainless steel or duplex alloys to resist pitting and crevice corrosion in chloride-laden atmospheres. Serialized with material test reports for full traceability.
Enables retrofit of existing carbon steel lines into new stainless steel systemsEvery expansion joint and flange assembly is hydrostatically tested at 1.5 times the rated pressure before shipment. Test pressures are recorded and certified per ASME B31.3. We also offer pneumatic testing for gas-service components upon request.
Verifies structural integrity before installationOur field engineers provide installation supervision, bolt-torque verification, and leak-check services for new piping tie-ins. We also offer training for maintenance crews on proper gasket installation and flange alignment procedures.
Reduces commissioning delays and startup leaksEvery component is designed for total volumetric containment of highly corrosive process fluids under extreme thermal and pressure cycling. Here is how we deliver that promise.
Transition flanges use a nickel-alloy interface that electrically isolates carbon steel from stainless steel. This eliminates galvanic corrosion at the joint — the most common failure point in retrofit piping networks.
Reinforced elastomeric seals combine broad chemical resistance with sustained elastic recovery. The stainless steel insert ring prevents extrusion at high pressure, and each seal is qualified for EPA Method 21 fugitive emission service.
Every expansion joint is certified for ASME B31.3 compliance. Multiple-ply stainless steel bellows handle thermal cycling in caustic environments without creep or fatigue failure.
Each flange and joint comes with a material test report certifying chemical composition and mechanical properties. No guesswork during installation or inspection — full chain of custody from forge to field.
Straightforward answers about our high-pressure expansion joints, transition flanges, and reinforced elastomeric seals for heavy-duty piping networks.
The Series 4000 expansion joint is rated for 600 psi at 450°F, with hydrostatic testing to 1.5 times the rated pressure. Each unit is certified for ASME B31.3 compliance, making it suitable for aggressive thermal cycling in chemical processing environments.
The Type TF-200 uses a precision-forged bimetallic interface with a nickel-alloy barrier layer that electrically isolates carbon steel from stainless steel. This design eliminates galvanic corrosion at the connection point, and each flange comes with a material test report for both metals.
Yes, the Model R-77 seal is specifically designed for VOC and hazardous air pollutant containment. It features a PTFE outer envelope bonded to a fluoroelastomer core, with a 304 stainless steel insert ring to prevent extrusion. It meets EPA Method 21 leak detection standards for fugitive emission service.
Expansion joints are available in nominal diameters from 2 to 24 inches with custom lengths. Transition flanges are drilled to ANSI B16.5 class 150 dimensions. Seals come in standard pipe sizes from 1/2 to 12 inches, with custom profiles for non-standard flange configurations.
Every product ships with a material test report certifying chemical composition and mechanical properties. Expansion joints include ASME B31.3 compliance certification. All units are serialized for full traceability.
