Pipe Schedule Chart

Pipe plugs are considered pipe fittings. Pipe fittings are components used to connect, terminate, control flow, or change the direction of piping systems. Pipe plugs specifically are used to close off the end of a pipe temporarily or permanently. We manufacture and carry various designs, including expansion plugs, and mechanical plugs, among others. While pipe plugs may serve different purposes depending on the operator's application, they are classified as pipe fittings due to their function within piping systems.

Isolation Plugs ...

are used to isolate specific sections of pipelines or vessels during maintenance, repairs, or modifications. These expansion plugs, are inserted into a pipeline to create a temporary seal, effectively blocking the flow of fluids or gases through the isolated section. By isolating portions of the pipeline, operators can conduct maintenance activities without the need to shut down the entire system, thereby minimizing downtime and operational disruptions.

Hydrostatic Test Plugs ...

are used for pressure testing pipelines, valves, and other pressure-containing components to verify their structural integrity and leak-tightness. These plugs are inserted into the pipeline and pressurized with water or another suitable test medium to simulate operating conditions. By subjecting the system to hydraulic pressure, operators can detect any leaks, weaknesses, or defects in the pipeline or its components.

Hydrostatic testing is a crucial quality assurance measure, especially during pipeline construction, maintenance, or repairs, ensuring compliance with industry standards and regulations while enhancing safety and reliability.

A Critical Reminder: Conducting pressure testing poses significant hazards, demanding strict adherence to safety protocols. Ensure all connections, valves, flanges, and fittings are suitable for pressure testing. Verify the compatibility of line ID & Plug Range. Most importantly, never position yourself in front of a test plug or enclosure during testing. Discharge from a plug during testing could result in severe injury or fatality.
