Why MetalRein
Standard Models — Select by Tap Diameter
Standard models are selected primarily by required tap hole diameter. Electric-driven and manual. Spindle extendable 100 mm. Special requirements can be discussed.
Triple-Tested Before Shipment
Every machine completes three pressure simulation tests before shipment. Results are documented and traceable. No machine ships without completing this process.
40+ Years of Manufacturing Heritage
Chongqing-based manufacturer with founding team behind China's first hot tapping machine. Critical components manufactured in-house to ±0.02 mm — not sub-contracted.
Featured Product
Hot Tapping Machines
Branch connections on live, pressurised pipelines — no service interruption required. Electric and manual models are available, with a standard drilling diameter range of DN25–DN1200. Sizes above DN1200 can be discussed as custom requirements.
Standard models are matched primarily by required tap hole diameter. Pipe size, material, medium, pressure, and site conditions can be included where relevant to help confirm accessories, sealing, and any special requirements.
How to start an enquiry
Start with required tap hole diameter, drive preference, and quantity. Supplementary details — pipe size, material, medium, pressure — are helpful where available, but not required to begin. We respond within 24 hours.
Tap hole diameter first. Add supplementary details where available.

How standard model matching works
Most enquiries can be matched quickly. The primary input is the required tap hole diameter. Drive preference and any special requirements are noted where relevant. Other details are helpful if available, but you do not need complete project documentation to start.
Standard models cover most enquiries. Spindle extension 100 mm and limited small adjustments can be discussed. For special high-pressure or oilfield applications, custom feasibility can be assessed from the specific operating conditions; the final capability range is subject to engineering review and written confirmation.
What to include in your enquiry
- Tap hole diameter is the primary selection input — state this first
- Other information (pipe size, material, medium, pressure) provided as supplementary context
- Special high-pressure or oilfield applications — custom feasibility assessment and written engineering confirmation
- Spindle extension required (100 mm available as standard option)
- Project pipe size above DN1200 — custom feasibility assessment required
Tap hole diameter is the main matching input
Standard models are selected primarily by required tap hole diameter. Electric or manual drive. Spindle extendable 100 mm. Most enquiries can be matched and quoted quickly.
Standard models cover most enquiries
Most projects fall within the standard range — DN25 to DN1200. Other details such as pipe material and medium help confirm sealing and accessories.
Supplementary details are helpful, not required to start
Wall thickness, material, medium, pressure, and site notes help confirm sealing configuration and accessories. You do not need complete project documentation to begin an enquiry.
Special requirements can be discussed
For special high-pressure or oilfield applications, note the specific operating conditions in the enquiry. Custom feasibility can be assessed; the final capability range is subject to engineering review and written confirmation.
Is this the right fit?
MetalRein is suited to projects where live-line connections are required, service shutdown is not an option, and standard models are matched to confirmed operating conditions.

Frequently Asked
What do I need to start an enquiry?
Primarily: required tap hole diameter, quantity, and drive preference (electric or manual). Other details — pipe size, material, medium, pressure, temperature — are supplementary context. Submit what you have; we respond within 24 hours.
Can I enquire before I have all the project details?
Yes. Tap hole diameter is the key input. Other information helps confirm sealing configuration and accessories — but you don't need everything before starting. Submit what you have and note any uncertain figures.
What types of projects is MetalRein suited to?
Projects requiring branch connections on live, pressurised pipelines without service shutdown — municipal water, gas distribution, industrial process lines, and petrochemical applications. Standard models cover most applications; special requirements can be discussed.
Can projects above DN1200 be handled?
Yes — subject to feasibility assessment. DN25–DN1200 is the standard range. Sizes above DN1200 require a custom feasibility review. Submit pipe size, wall thickness, material, medium, and operating pressure to start the assessment.
What is MetalRein's standard working pressure?
Standard working pressure is 1.6 MPa; up to 2.5 MPa depending on model and application. The 2.5 MPa figure is not the default value for every standard model. Provide your actual operating pressure as supplementary context.
What happens after I submit an enquiry?
We match standard models to your tap diameter and respond within 24 hours — confirming the applicable model or asking follow-up questions. If special requirements apply, we discuss feasibility. Price quotation follows once model and configuration are agreed.
