Hot Tapping And Stopples Service

1. Hot Tapping Hot Tapping is the process of making a connection to an existing pipeline or pressure vessel while it remains in service. This is achieved by welding a branch connection (such as a fitting or valve) to the pipe and then using a specialized drilling machine to cut an opening into the pipe wall.

● Applications:

● Adding new branch lines or connections.

● Installing instrumentation or monitoring probes.

● Bypassing sections of pipe for maintenance.

● Benefits:

● Zero Downtime: Operations continue uninterrupted during the procedure.

● Cost-Effective: Eliminates the costs associated with shutting down, depressurizing, and purging the system.

● Environmental Safety: Prevents the release of product into the atmosphere.

2. Stopples Stopples are mechanical pressure-actuated plugs used to isolate a section of a pipeline. They are inserted into the pipe through a hot-tapped opening. Once in position, the stopple is expanded to seal against the pipe wall, effectively blocking the flow of product. This allows work to be performed on the isolated section (such as valve replacement or pipe modification) while the rest of the system remains pressurized and operational.

● Applications:

● Isolating damaged sections of pipe for emergency repair.

● Replacing valves, flanges, or meters.

● Decommissioning sections of a pipeline.

● Benefits:

● Targeted Isolation: Only the specific section requiring work is isolated.

● High Pressure Capability: Designed to withstand high operating pressures and various media (gas, oil, water, chemicals).

● Retrievable: Once the work is complete, the stopple can be retrieved via a hot tap machine, and the opening is sealed with a plug.

Technical Specifications & Capabilities

● Operating Pressure: Capable of working on lines ranging from low pressure up to high-pressure transmission mains (e.g., up to 100 bar or higher depending on specific equipment).

● Pipe Sizes: Services available for pipe diameters ranging from small bore (e.g., 2 inches) to large transmission lines (e.g., 48 inches+).

● Compatible Media: Suitable for crude oil, natural gas, steam, water, chemicals, and refined products.

● Safety Standards: All procedures are conducted in strict compliance with international safety standards (such as ASME, API, or

ISO standards) to ensure the integrity of the weld and the safety of personnel.
