Hot Tapping Fitting Series
JSW Hot Tapping Fittings are engineered precision components that enable safe, efficient, and pressure-critical branch connections and pipeline isolation on live oil, gas, chemical, and municipal pipelines, eliminating costly shutdowns and maximizing operational uptime for contractors and companies worldwide.
Core Advantages
-
Zero-Downtime Installation: Perform branch connections or install isolation equipment on fully pressurized pipelines, ensuring continuous flow and revenue.
-
Engineered for Safety & Reliability: Designed to meet stringent ASME B31.3, B31.8, and GB standards, providing a leak-proof, pressure-containing seal for high-risk environments.
-
Unmatched Versatility & Customization: Available in pressure classes from Class 150 to Class 900 (4.0MPa to 10.0MPa), in materials like A516, Q345R, and configurable as Full-Encirclement Split Tees, Line Stop Fittings, or custom outlets.
-
Total Project Cost Reduction: Dramatically lowers the indirect costs associated with pipeline shutdowns, product loss, and extended project timelines, offering the best value for sale.
Detailed Product Description
Our hot tapping fittings, such as the Split Tee, form the foundational pressure boundary for safe pipeline interventions.
-
Fitting Installation: The Split Tee fitting is welded onto the live pipeline. Its full-encirclement design reinforces the pipe.
-
Hot Tap Operation: A hot tapping machine is bolted to the fitting’s outlet, drills into the pipe under pressure, and is retracted with the coupon.
-
Line Stop or Branch Connection: For isolation, a Line Stopper fitting and plugging machine are installed. For a branch line, a valve and piping are connected immediately.

Core Component Focus:
-
Split Tee Body: The main pressure vessel, typically a Full-Encirclement Split Tee, provides 360° reinforcement. Our KJ Series includes an integral reinforcing pad for added safety.
-
Outlet Nozzle: Precision-machined to provide a true, flush connection for the hot tapping machine or valve.
-
Gasket & Sealing System: High-integrity gaskets ensure a bubble-tight seal between fitting halves and against the pipeline, critical for pressure-activated sealing.
Solving Core Pain Points
Client Pain Points Addressed:
-
“A pipeline shutdown for a simple tie-in costs us millions in lost production. Is there a solution?”
-
“We need to isolate a section for repair, but depressurizing the entire network is not an option. What equipment can guarantee safety?”
-
“Our project involves varied pipe grades and pressures. Can one supplier provide a customized, code-compliant solution?”
-
“We are concerned about the long-term integrity of a welded branch connection on an aging pipeline.”
Application Scenarios:
-
Scenario 1: New Branch Connection (Hot Tap): Adding a new line to an active crude oil transmission pipeline without stopping flow.
-
Scenario 2: Pipeline Isolation (Line Stopping): Using Line Stop Fittings and Pipeline Isolation Plugs to bypass and repair a damaged section of a city gas distribution network.
-
Scenario 3: Emergency Repair: Rapid deployment of a Stopple Fitting to temporarily isolate a leak, allowing for safe repair.
-
Scenario 4: Modifications & Upgrades: Installing meter runs, sampling points, or pressure relief lines on live process piping in a chemical plant.
Comparative Advantage: Why Choose JSW?
vs. Traditional Shutdown Methods:
| Factor | Traditional Shutdown & Replace | JSW Hot Tapping Fittings Solution |
|---|---|---|
| Downtime | Days to Weeks | Zero – Operations continue |

FAQ (Frequently Asked Questions)
Q1: Can JSW fittings be used for both hot tapping and line stopping?
A: Absolutely. Many of our Hot Tapping and Plugging Fittings, like the Full-Encirclement Split Tee, are designed as dual-purpose fittings. They first serve as the pressure boundary for the hot tap, and then can accommodate a Line Stopper fitting for isolation, making them incredibly versatile solutions.
Q2: What information do you need to provide a quote?
A: To provide an accurate price and design, we require: Pipeline OD & WT, Material Grade, Operating Pressure/Temperature, Desired Pressure Class (e.g., Class 300), Connection Type (flange spec/rating), and a brief description of the application (hot tap, line stop, etc.).
Q3: Do you offer installation services for your fittings?
A: As a manufacturer, we focus on engineering and supplying the highest-quality Pipeline Plugging Fittings. We highly recommend installation by qualified, experienced pipeline contractors. We can provide certified installation procedures and technical support to your chosen service team.
