Mechanical Research & Design, Inc. Pipe Plugs

Mechanical Research & Design, Inc. has been providing innovative and proven Pipe Plugs all over the world for nearly 25 years. Also called pressure test plugs, pipe stoppers, pipe bungs, line stops, or inline isolation tools, pipe plugs are a common pipeline pressure test and isolation barrier tool for both newly fabricated or existing piping systems. Mechanical Research & Design, Inc. designs and manufactures many standard, off the shelf configurations as well as custom, application specific barrier options for low, medium, and high pressures (most styles from vacuum test pressures through several thousand PSI). We supply round plugs, rectangular plugs, irregularly shaped plugs that can be used in pipelines (carbon steel, stainless steel, ductile iron, polymer, composite, ceramics, concrete, to name a few), tubing, tunnels, shafts, bores, hoses, assembled components, water intakes, and nearly any part that requires pressure or leak testing. MRD supplies several types of Pipe Plug sealing systems, the most popular being Mechanical Pipe Plugs, Inflatable Pipe Plugs, and Combination Mechanical + Inflatable Pipe Plugs. The tools can be manufactured from nearly any material imaginable for temporary or long term installations, in standard test configuration use or even in corrosive, temperature extreme environments. Our Pipe Plugs are designed to last and are rugged enough to be used again and again in remote location field services, offshore oil & gas, subsea and for underwater construction, as well as in heavily regulated industries, such as nuclear power.
