Our Line Stop Equipment Services

Purpose-built equipment and components for hot tapping, pipeline isolation, and reliable line stop completion.

Line Stop Equipment

Complete line stop equipment manufactured for every stage of pipeline isolation, including folding heads, pivoting heads, housings, actuators, flanges, and completion tools.

Folding Heads

Folding head line stop machines provide a cost-effective approach for smaller taps, valves, and fittings while supporting controlled isolation of pressurized pipeline sections.

Line Stop Flanges

Completion flanges feature sealing push-style completion plugs secured with accessible set pins. Contoured nozzles can be supplied for direct welding onto pipe.

Completion Plug Setters

Completion plug setting machines finish line stopping jobs without relying on a large tapping machine and tapping adapter. Available models cover a range of plug sizes.

Jackscrews & Actuators

Jackscrews and actuators are manufactured as essential line stop components, providing the controlled mechanical movement needed throughout the isolation process.

Custom Line Stop Equipment

Custom tapping and line stopping equipment is manufactured to suit exact job requirements, helping customers service pipelines of virtually any size with effective solutions.

Pipeline Control Solutions

Choose the Right Isolation Method

Line stops and insertion valves both support work on pressurized pipelines, but they serve different operating needs. A line stop temporarily isolates a pipe section so crews can repair, replace, or maintain downstream assets without a full service interruption. An insertion valve creates a permanent, operable valve point in an existing line. Schallert Enterprises supplies the specialized equipment and components behind both types of in-service work.

Frequently Asked Questions

What is the difference between a line stop and an insertion valve?

A line stop is a temporary isolation method used to block flow through a section of pressurized pipe so crews can repair, replace, or maintain downstream assets. An insertion valve is installed through a hot tap to create a permanent valve location that can be opened or closed later. The right option depends on whether the project needs temporary isolation or lasting control.
