• Wide Range & Durability: Covers a broad spectrum of pipeline sizes (from DN150 to DN1400 / MPS6 to MPS56) with pressure ratings up to 10MPa. Built as a durable, long-lasting capital asset for your company.

• Clear Operational Control: Features a travel indication system for precise plug positioning, giving the operator full confidence during the critical setting process.

Detailed Product Description & Technical Specifications

How It Works: The Secure Plug Setting Process

The SDQ Tapping Plug Setting Assembly is deployed after a hot tapping operation. It is flanged to the installed tapping fitting. The operator then precisely advances the plug stem into the pipeline, positioning the attached plugging head (like a pipe stopper or inflatable plug line stop) at the predetermined location. The plug’s sealing element engages with the pipe’s inner diameter, creating a pressure-tight barrier that isolates the downstream section. This allows for the safe removal of temporary equipment and facilitates downstream work.

SDQ Series Technical Specifications

Our SDQ Tapping Plug Setting Assembly is available in three primary models to match your pipeline dimensions and pressure requirements.

Note: Base and plug stem flange dimensions are customizable per client specifications.

Optional Accessories:

Plug and Blocking Coupler

Note:

1. The flange dimensions and pressure rating of the plug and blocking coupler can be customized according to user requirements.

2. P indicates the pressure rating of the coupler.

Core Components & Build Quality

• Robust Frame & Base: Heavy-duty, flanged construction provides stability and secure attachment to the pipeline fitting.

• Precision Feed Screw / Hydraulic Ram: Ensures smooth, controlled linear advancement of the plug stem. The optional hydraulic module on larger models significantly speeds up the process.

• Travel Indication System: A clear scale or digital readout allows the operator to monitor plug insertion depth accurately, critical for proper seal engagement.

• High-Grade Materials: Manufactured from hardened alloys and steels suitable for high-pressure and corrosive service environments, ensuring the longevity of your equipment investment.
