Selecting the right hot tap machine can make the difference between a smooth, efficient project and unnecessary complications on site. Whether you are working on a district heating network, a process plant, or a gas distribution system, the equipment you choose needs to match the pipe size, material, and operating conditions of your specific application. Making an informed decision upfront saves time, reduces costs, and ensures reliable results.
We offer two hot tap machines designed for different project requirements: the compact Jr model and the more versatile B30. Both machines enable under-pressure maintenance, allowing you to create new branch connections without shutting down the pipeline. If you are planning a hot tapping project and want professional guidance, explore our hot tapping services to see how we can support your work from evaluation through installation.
What Sets Tonisco Jr and B30 Hot Tap Machines Apart
Hot tap machines are specialized drilling devices that create openings in pressurized pipelines while the system remains fully operational. This capability is essential for industries where service interruptions are costly or impractical, including HVAC networks, oil and gas distribution, water utilities, and process industries. The machine securely attaches to a fitting on the pipeline, drills through the pipe wall under controlled conditions, and retracts the cutter while maintaining pressure integrity.
The Jr and B30 represent two distinct approaches to hot tapping. The Jr is engineered for smaller branch connections, offering portability and ease of use in confined spaces. The B30 handles a broader range of pipe sizes and provides greater flexibility for medium-scale projects. Both machines reflect decades of Finnish engineering expertise and are built to perform reliably across diverse pipeline materials and conditions.
Understanding how hot tapping works on pressurized pipelines helps clarify why machine selection matters. The right equipment ensures clean cuts, proper sealing, and safe operation throughout the process.
When to Choose the Compact Tonisco Jr for Smaller Branches
The Jr hot tap machine is purpose-built for smaller-diameter work, handling pipe sizes from DN20 (3/4″) to DN100 (4″). This makes it ideal for service connections, instrumentation taps, and sensor installations where a compact, maneuverable machine delivers clear advantages. The lightweight design allows technicians to work efficiently in tight spaces where larger equipment simply cannot fit.
Key specifications and typical applications for the Jr include:
- Pipe size range: DN20 (3/4″) to DN100 (4″)
- Compact footprint suited for confined installation areas
- Ideal for district heating branch connections
- Well suited for instrumentation and sensor installations
- Compatible with various valve adapters, including Broen, Danfoss, Vexve, Böhmer, and our own fittings
For contractors who frequently work on residential or commercial building connections, the Jr offers an efficient solution. The Jr WT Gold Line Set provides a complete package with matched components for immediate deployment. If you have questions about material compatibility or special requirements for your project, we recommend contacting our sales team for guidance.
Why the Tonisco B30 Excels for Larger Pipeline Projects
The B30 hot tap machine extends your capabilities to larger-diameter pipelines, covering sizes from DN40 (1½”) to DN200 (8″). This expanded range opens up applications in industrial facilities, main distribution lines, and infrastructure projects where branch connections need to accommodate higher flow volumes. The B30 maintains precision and reliability while handling the increased demands of larger-scale work.
Key specifications and typical applications for the B30 include:
- Pipe size range: DN40 (1½”) to DN200 (8″)
- Suitable for main line modifications and larger branch connections
- Process industry applications requiring medium-diameter taps
- District heating and cooling network expansions
- Compatible with valve adapters from Broen, Danfoss, Vexve, Böhmer, and our own fittings
The B30’s versatility makes it a practical choice for contractors who encounter varying project requirements. The B30 WT Gold Line Set bundles the machine with complementary components for streamlined operations. Understanding what equipment is needed for hot tapping helps ensure you have everything required for successful execution.
Key Factors for Selecting the Right Hot Tap Machine
Choosing between the Jr and B30 starts with understanding your project parameters. The comparison below highlights the primary differences to guide your decision:
| Feature | Jr | B30 |
|---|---|---|
| Pipe Size Range | DN20 (3/4″) to DN100 (4″) | DN40 (1½”) to DN200 (8″) |
| Drive Options | Manual, electric, pneumatic, hydraulic | Manual, electric, pneumatic, hydraulic |
| Typical Industries | HVAC, district heating, water networks | Process industry, oil and gas, larger HVAC systems |
| Best For | Service connections, sensor installations | Main line modifications, medium-diameter branches |
Both machines support multiple drive unit options to match your operating environment. Manual drives work well for occasional use or locations without power access. Electric drives offer consistent performance for routine operations. Pneumatic options suit environments where compressed air is readily available, while hydraulic drives deliver maximum power for demanding applications.
If you are unsure which machine suits your project, we recommend contacting us. Together with our professionals, you can assess your specific requirements and choose the most appropriate solution. For projects involving PE pipes or other special materials, consulting our sales team ensures you select compatible equipment.

How Tonisco Hot Tap Machines Enable Under-Pressure Maintenance
Under-pressure maintenance eliminates the need for costly system shutdowns, keeping operations running while modifications or repairs take place. Both the Jr and B30 are engineered to perform hot tapping safely and efficiently on live pipelines, minimizing disruption to end users and reducing the environmental impact associated with draining and refilling systems.
The process involves securing the hot tap machine to a valve or fitting already installed on the pipeline. The machine then advances a cutter through the valve and into the pipe wall, creating a precise opening. Once complete, the cutter retracts, and the valve closes to maintain system pressure. This approach supports new branch connections, sensor installations, in-line leak detection points, and valve replacements without interrupting service.
Our hot tapping equipment supports branch sizes from DN10 (3/8″) to DN1600 (64″) across our full product range, handling pipeline materials including steel, PE, composite, and stainless steel. This flexibility means you can address diverse project needs with proven, reliable equipment. For projects requiring professional execution, contact us to discuss your requirements with our team.
