Low-Pressure Pipeline Isolation Plugs

A folding head plug can be inserted through a smaller tap or valve than the actual pipe diameter. This significantly reduces costs by requiring smaller, less expensive fittings and valves for the line stop operation, minimizing both equipment expense and installation time.

Our low-pressure isolation plugs are designed for systems with sealing elements rated up to 150 psi (10.3 bar). While some components like the folding head itself may have higher pressure ratings, the operational limit is determined by the sealing element's capacity.

This specific category covers our models for 12-inch and 20-inch pipelines. We manufacture a full range of hot tapping and line stopping equipment capable of servicing pipelines from 3/4 inch up to 84 inches in diameter for various pressure ratings.

They are primarily used for line stopping operations in water, wastewater, and industrial pipelines. Common tasks include replacing faulty valves, repairing damaged pipe sections, and installing new branches, all while the rest of the pipeline remains active and in service.

Yes, when used in pairs, our isolation plugs are ideal for creating a bypass. By isolating a section of pipe between two plugs, flow can be rerouted through a temporary external line, allowing for extensive repairs or replacement of that section without service interruption.

Our sealing elements are typically made from high-quality polyurethane. This material provides excellent sealing capabilities and durability for reliable pipeline isolation in a variety of standard water, wastewater, and industrial fluid applications.
