Mechanical Research & Design, Inc. is well known for our temporary and permanent Isolation Pressure Barriers and Bulkhead Products. Constructors and technicians have safely worked behind our single point isolation pressure barriers using our reliable single or redundant SEALFAST® Inflatable and Mechanical Seals for decades. We can adapt to nearly any existing or new build infrastructure, including engineered anchor-in-place, strong-back, convenient restraint screw, and other proprietary restraining systems. We design, fabricate, and test our products to nearly any size, shape, or pressure rating, specializing in innovative installation work plans. Our clients trust us time and time again because we have a long, proven history of success with our designs.
• Shaft, Tunnel, Drift, Duct, Channel, Intake Isolation Barriers
• Pressure Rated Grout and Concrete Forms
• Temporary and Permanent High Flow Bypass Barriers
• Fluid and Waste Containment Barriers
We design and manufacture a wide variety of shape, size, and pressure rated, Pipeline Isolation and Pressure Test Plugs. Similar to our large isolation barrier product lines, we utilize an array of load-rated integral restraint systems, coupled with our field proven SEALFAST® Inflatable and Mechanical Seals, providing the most trusted products on the market. Our plug designs can range from permanent, long-term pressure barriers to those focusing on rapid installation and deployment, such those found in pipeline pressure testing. Mechanical Research & Design, Inc. provides solution product lines for carbon steel, stainless steel, ductile iron, PVC, FRP, and concrete pipe as well as for thin wall tubes, to name a few. If you have it, we can seal it! Give us a call today!

Many of our Isolation and Test Tools can be used standard or customized for Underwater and Marine Construction. We have worked with Diving Technicians, Constructors, and ROV Operators for decades, designing and optimizing tools specifically for the challenges that exist in subsea, gray and blackwater diving environments. Our tools are commonly used to service valves, sea chests, underwater pipelines, submerged intakes, hydroelectric penstocks, and for general construction zone water isolation. Many of our products are also used as direct gates for channels, ducts, and shafts. Call us today to work with one of our experienced Marine Engineers.

Use SEALFAST® Inflatable and Mechanical Joint Testers to verify pipeline joint and weld integrity progressively, connection by connection, without filling and pressurizing entire piping systems. We have Joint Testers that flex around elbows, that split and break down to fit through smaller cross-sections (manholes), and that test multiple size pipes at the same time. We have product lines for pressure ranging from vacuum pressure to over 5000 psi for round pipes, out of round piping systems, rectangular, and irregular shaped cross-sections.
• Pipeline Weld/Joint Testing (Single Joint Verification)
• Flange Joint/Weld Pressure Testing
• Tee and Cross Fitting Isolation
See our line of Annular Sealing Tools and Grout Packers. These products can be used to provide temporary to permanent seals in wall piping penetrations, can pressure test between double containment piping, or can be used for grout forms when pumping in the annular spaces between pipes. We can fabricate these products to be in single pieces, split for installation into existing piping systems, and much more. SEALFAST® Annular Seals can be designed for eccentric or misaligned piping systems and are incredibly flexible as debris blocks and self-contained pressure barriers.
