Pipeline Equipment

Split Tee Fitting

In the high-stakes world of oil, gas, chemical, and municipal pipeline operations, unplanned shutdowns are not an option. Whether you’re planning maintenance, adding a branch line, or performing emergency repairs, you need a reliable, safe method to isolate sections of pipe without shutting down the entire system. This is where the Split Tee Fitting becomes the cornerstone of modern pipeline integrity management.

Our Split Tee Fittings are engineered precision equipment designed specifically for Hot Tapping and Plugging applications, enabling contractors and pipeline operating companies to perform work under pressure—safely and efficiently. At JSW Pipeline Services, we are a leading manufacturer and supplier of these critical systems, providing a complete, certified solution for your most demanding projects. Don’t let pipeline maintenance dictate your downtime. Explore our high-quality Split Tee Fittings for sale and discover the JSW advantage.

Product Overview

The “SealLock” Series Split Tee Fitting: Engineered for Zero-Downtime Pipeline Interventions.

A Split Tee Fitting is a specialized pipeline plugging fitting that allows for the safe installation of a temporary or permanent plugging head (or “Stopple”) into a live pipeline. It consists of two halves that are bolted around the pipe, creating a pressure-containing enclosure with branch outlets. This enables hot tapping followed by the insertion of a plugging device to isolate a section of the line—all without stopping the flow.

Core Value : JSW’s Split Tee Fittings provide pipeline operators and engineering contractors with a safe, code-compliant, and highly adaptable method for performing critical line stops, tie-ins, and repairs, eliminating costly production shutdowns and minimizing operational risk.

Key Advantages

  • Unmatched Safety & Reliability: Designed and manufactured to the most stringent global standards (ASME, GB), our fittings are pressure-tested to exceed rated capacity, ensuring absolute integrity during line stop fitting installation.

  • Maximum Operational Flexibility: Available in a wide range of pressure classes (Class 150 to Class 900 / 4.0MPa to 10.0MPa) and materials, they adapt to diverse pipeline specifications and media, from natural gas to corrosive chemicals.

  • Engineered for Efficiency: The split design allows for rapid installation compared to full-wrap enclosures. Our comprehensive kits include all necessary tools and components, reducing project planning time and on-site delays.

  • Long-Term Asset Protection: Facilitates safe hot tapping, allowing for future connections or interventions without the need for additional major welding on the live pipe, preserving its long-term structural integrity.

Detailed Product Description

Our Split Tee Fittings are integral to a proven line stop procedure:

  1. Preparation & Installation: The two halves of the Split Tee are positioned around the pipe and securely bolted together, forming a sealed pressure housing.

  2. Hot Tapping: A hot tapping machine is connected to the branch outlet of the fitting to cut into the live pipeline, with the coupon retained.

  3. Plugging Device Insertion: A specialized plugging head (Line Stopper or Stopple) is inserted through the fitting and into the pipeline.

  4. Isolation & Work: The plug is activated, creating a seal and isolating the downstream section. Work (repair, modification, valve installation) can then be performed safely.

  5. Completion: After work is done, the plug is retrieved, the line is restored, and the branch valve on the Split Tee is closed. The fitting remains as a permanent, future-ready asset.

Solving Core Challenges

Addressing Critical Pain Points for Pipeline Companies

  • “Can we avoid a total system shutdown for this repair or modification?” Yes. Split Tee Fittings enable safe work on isolated sections, keeping the rest of the line operational.

  • “Is hot work (welding) on a live line too risky for this location?” Absolutely. Our fittings allow the critical pressure containment structure to be installed safely, minimizing live welding.

  • “We need a solution that works for different pressures and pipe grades across our network.” Our customizable fittings are designed to meet your exact pressure class and material specifications.

  • “We need future-ready assets, not just a one-time fix.” Once installed, the Split Tee becomes a permanent tapping point for future maintenance or connections, adding long-term value.

Application

  • Emergency Pipeline Repair: Isolate a damaged section (e.g., from corrosion or third-party damage) to perform a safe cut-out and replacement while maintaining service.

  • System Modification & Tie-Ins: Add new branches, valves, or instrumentation to an existing pipeline without depressurizing the entire network.

  • Preventive Maintenance & Inspection: Facilitate the insertion of inspection tools or the isolation of sections for internal cleaning or inspection.

  • Plant Turnarounds: Isolate specific sections of complex piping within facilities for efficient, staged maintenance.

Client Testimonials & Project Success

Case Study: Rapid Response Gas Line Modification

  • Client: A major urban gas distribution company.

  • Challenge: Need to add a critical pressure regulation station to a high-pressure gas main serving a metropolitan area. A full shutdown was commercially and socially unacceptable.

  • JSW Solution: Provided custom-designed Split Tee Hot Tap Fittings (Class 600, matching pipe material) and full technical support for the line stop procedure.

  • Result: The tie-in was completed successfully under full line pressure. The gas supply to the city was maintained without a single service interruption. The project was completed 5 days faster than a shutdown scenario, saving an estimated $2M in avoided revenue loss.

Frequently Asked Questions (FAQ)

Q1: Can a Split Tee Fitting be used for both hot tapping and line stopping?

A: Yes, absolutely. This is its primary function. The Split Tee is first installed and then used as the pressure-containing housing for the hot tapping machine to create an opening. Subsequently, the same fitting is used to guide and house the line stopper fitting (plugging device) to isolate the line. It is the fundamental component of a Hot Tapping and Plugging system.

Q2: What is the main difference between a Split Tee and a Welding Tee for hot taps?

A: A traditional welding tee requires the entire fitting to be welded around the circumference of the live pipe—a time-consuming and higher-risk hot work activity. A Split Tee consists of two halves that are bolted on, significantly reducing the amount of welding required on the live line. This enhances safety, speeds up installation, and is often mandatory for higher-risk or higher-pressure applications.

Q3: How do I determine the correct pressure class and material for my project?

A: The fitting must meet or exceed the design pressure and temperature of the pipeline and be compatible with the pipe material and the transported medium. Our technical team will guide you through this process. Key inputs needed are the pipeline’s MAOP (Maximum Allowable Operating Pressure), design temperature, pipe material grade/spec, and the nature of the service (e.g., sour gas, crude oil). We then design or select the fitting to appropriate codes like ASME B31.3 or B31.8.
