Company Description:

Petersen Products: 100 Years of providing custom solutions for the pipeline industry.


One of Petersen Products’ most popular systems – the 129-series “Multi-Flex” Plug system – plugs a pipe without depressurizing the pipeline.


The proprietary Multi-Flex line stop plugs are Petersen Products’ answer to the problem of having an entire water-cooling system in a factory shut down. The 129-series are inflatable bladder plugs, which can be installed and removed easily – enabling workers to close off sections of pipe while the rest of the system keeps running. They are designed to plug a pressurized pipeline without reducing the pressure so repair work can be done downstream – replace a valve, cut in a fitting, or replace a section of pipe.


Another unique product is the inflatable Annular Seal. This seal fills the annular space between a smaller inner pipe and a larger one providing a quick temporary connection. The Petersen Annular seal’s many uses include grouting boreholes and bypassing a large pipeline during repairs.

Petersen provides plugs for almost any size, pressure, chemical, and temperature. Their primary market is major pipeline contractors, industrial plants, and municipalities. They have many standard-configuration mechanical and inflatable plugs in inventory. It is Petersen Products’ ability to quickly create custom solutions or ship standard items immediately that has earned them a reputation as problem solvers – all over the world.


One example of a Petersen solution includes a 23-foot diameter tunnel in the largest uranium mine in the world, the Cigar Lake uranium mine in Canada. It had sprung a leak and was filling with water – and the mining company felt they had to abandon it. Petersen Products built an inflatable tunnel seal that could be pulled down into the space to seal it off, all using remote equipment. Once it was in place the seal was filled with concrete, stopping the flow forever, and saved the mine.”


Today Petersen deals with higher pressures, higher temperatures, and more challenging chemicals than ever before. Each challenge brings new knowledge that is then applied to all future projects honoring their motto. “We provide solutions."
