Reliable Line Stopping Equipment Solutions

Line stops are temporary pipeline isolation systems used to stop flow through a specific section of pipe while maintenance, repairs, valve replacement, or pipeline modifications are performed. They allow work to proceed without shutting down the entire system. A typical setup uses a fitting or flange, a line stop head, an actuator, and completion equipment to isolate the targeted section safely and controllably.

A line stop procedure generally begins by planning the isolation and selecting compatible equipment. A connection is prepared on the pipeline, then a tapping operation creates access to the pressurized line. The line stop head is inserted and positioned to isolate flow. After the required repair or replacement, a completion plug is set, the stopping equipment is removed, and the connection is secured.

Schallert Enterprises offers cost-effective line stopping solutions for lines from 5 to 84 inches in diameter. Equipment selection depends on pipe size, connection design, operating conditions, and the required isolation method. Line stop flanges are available in common sizes from 4 through 36 inches, while some larger sizes are available by calling for availability. Custom equipment can be manufactured for specialized needs.

The required equipment varies by application, but a line stop setup commonly includes a line stop fitting or flange, a folding or pivoting head, housing, actuator or jackscrew, and completion plug setting equipment. A hot tapping machine, tapping adapter, cutter, and pilot drill may also be needed to create access to a pressurized pipeline before the isolation device is installed.

Yes. Line stopping is designed to isolate a section of pipeline so maintenance, repairs, or replacement work can be completed without interrupting service across the full system. This makes it particularly valuable for water utilities, industrial facilities, and pipeline operators managing critical flow. Proper equipment selection, operating procedures, and trained field execution are essential to achieving a controlled isolation.

Both are line stop components used to establish controlled isolation, but they use different operating configurations. Folding heads are designed to reduce the size requirements associated with smaller taps, valves, and fittings, helping lower project costs on applicable jobs. Pivoting heads provide another configuration for positioning the stopping element during the isolation process. The appropriate choice depends on the pipeline and job requirements.

A completion plug setter installs the completion plug that finishes a line stopping job after the required pipeline work is complete. Schallert completion plug housings and setter machines allow a standalone completion operation rather than requiring a large tapping machine and tapping adapter. Available plug setters cover plug sizes from 6 to 36 inches, helping crews complete work efficiently.

Yes. Schallert Enterprises has the experience and manufacturing capability to build tapping and line stopping equipment around exact customer requirements. Customization can address pipeline size, equipment compatibility, connection details, and project-specific operating needs. The company also manufactures tapping adapters for any size tap and can make equipment to adapt to different tapping machines and plug-setting methods.
