HFT Pipestoppers offers large inflatable rubber plugs for high temperature pipes

avoiding excavation. Storm drainage pipelines, sanitary sewer lines and low pressure underground pipelines do not have valves or spectacle flanges to block fluid flow in the line.

The company’s customer base has grown considerably in the nearly 45 years that it has been serving the infrastructure industry and now represents many of its sectors including energy, water and sewer, construction, repair and testing, petrochemical and chemical.
