Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd is a Hangzhou-based manufacturer of pipeline connection equipment for fire protection, building services, municipal and industrial piping projects. We build the machines that prepare and join pipe — threading, tightening, cold cutting, drilling, pressure testing and oil-free air supply — together with the cordless tools and precision dies that keep those operations running on site. Our range is organised into three families: Pipe Fabrication & Installation Equipment, Cordless Power Tools and Precision Threading Dies & Accessories.
A Manufacturer Focused on Threaded Pipe Connection
Xinabo was established in 2010 and has concentrated on thread processing technology since. The founder's background in pipeline construction shaped the product direction: reduce the labour, time and cost of conventional threading while holding thread quality. Twelve years of development produced nine generations of intelligent threading machines, and the company now holds 30 patents and the National High-tech Enterprise designation.
Our equipment serves fire protection engineering, construction engineering, plumbing and MEP installation, and industrial piping. The same platform supports contractors producing threaded risers and mains, distributors stocking pipe tools, and plant engineers running in-house fabrication shops. As an Engineering Construction Pipeline Connection Solutions manufacturer, we supply the full sequence from pipe pretreatment to a tested, sealed joint.

Threading Machines: Capacity, Thread Forms and Control
The intelligent threading machine identifies pipe diameter automatically and sets the tool without manual adjustment, which removes the setup step that consumes most of the time on a conventional threader. Threading time is as low as 4 seconds on 15–25 mm pipe, and a single machine processes 1,500–2,000 pipe threads across an 8-hour shift.
- Working range: DN15–DN100 across the intelligent platform; 15–65 mm and 15–100 mm on the SQ65 and SQ100 electric machines.
- Speed control: three-stage gear shank at 127/45/21 r/min on the intelligent machine; dual speed at 25/40 rpm (SQ65) and 15/33 rpm (SQ100).
- Hydraulics: working pressure of 7.5–9 MPa on the intelligent machine, with automatic clamping through a toothed fixture.
- Thread forms: British (BSPT), American (NPT), Metric and customised non-standard threads, with dedicated die heads for each pitch family.
Cold Cutting, Drilling, Testing and Air Supply
A thread is only as good as the cut face behind it. The variable frequency cold saw produces a flat, burr-free edge without sparks or heat discolouration, so the die starts square and the finished thread seals against the fitting. Fire pipe drilling and electric pressure testing complete the sequence on installed systems.
- Cold saw: permanent-magnet variable frequency motor, precision shadow line guide and enhanced safety guarding; over 3,500 precise cuts per blade.
- Fire pipe drilling machine: branch and outlet preparation on fire mains without disturbing the installed run.
- Electric pressure test pump: hydrostatic verification of completed pipework before handover.
- Oil-free compressors: the F1200 series uses an oil-free design with intelligent auto start-stop; the F1680 series adds multi-cylinder compression and rapid air intake for higher-pressure demand.
Cordless Tools and Site Power
Where a cord cannot reach, our brushless cordless range covers cutting, grinding, drilling, punching, wrenching and spraying on a shared lithium-ion platform. The backpack lithium battery pack at 20 Ah or 30 Ah powers multiple tools in sequence, which suits crews working along a riser or across a large floor plate.
- Cutting and grinding: brushless angle grinder, brushless circular saw, brushless electric chainsaw and lithium hydraulic cutter for cable and pipe work.
- Drilling and fixing: lithium-ion brushless hammer drill/driver, rotary hammer, impact wrench and hole puncher for anchors, brackets and supports.
- Finishing: lithium-ion spray gun for touch-up and protective coating work without a compressor.
- Safety features: overload and overheat protection, automatic pressure relief after crimping, and safety locks against accidental start-up.
Threading Dies, Tooling and Consumables
Dies are matched to the machine, not selected by eye. Our double-edged dies are machined to the operating parameters of the intelligent threading machines, distributing cutting force across two edges to extend service life under continuous high-frequency use. High-speed steel dies are ground for electric threading machines and supplied in 4-piece sets covering 1/2"–3/4", 1"–2" and 2.5"–4", with BSPT and NPT profiles and chip-removal grooves sized for high-speed rotation.
Materials, Utilities and Installation
Our threading equipment is applied to carbon steel, galvanised, stainless steel, aluminium and copper pipe. Material hardness and wall thickness determine the speed stage and die selection, which is why the three-stage gear shank and adjustable torque matter more on mixed-material sites than on a single-specification run.
- Power supply: AC 380 V 50 Hz three-phase five-wire for the intelligent threading machine; 220 V for the pipe tightening machine and SQ65; 220/380 V for the SQ100.
- Handling: lifting ring and forklift pockets on the intelligent machine; mobile universal wheels with adjustable legs on the tightening machine and threaders.
- Site conditions: confirm available voltage, phase configuration and floor loading before positioning heavy units.
Quality Control, Compliance and Acceptance
Xinabo holds the National High-tech Enterprise designation and a portfolio of 30 patents covering threading machine mechanisms, die design, clamping devices and control functions. Our equipment is supported by a Machinery Directive and Electromagnetic Compatibility Directive Attestation of Conformity, and product certificates are issued for the relevant models.
- Incoming material control: screened raw material sources for dies, motors and structural components.
- Assembly and function testing: parameter verification against the rated working range before dispatch.
- Acceptance on site: sample threading and thread gauge checks, followed by hydrostatic pressure testing of the completed system.
Information We Use to Configure Your Solution
A configuration is built from the working point, not from a catalogue number. The following inputs let us match machine, die set and tooling to the project in one pass.
- Pipe data: diameter range, wall thickness and material, including any mixed-material runs.
- Thread specification: BSPT, NPT, Metric or a custom non-standard profile, with pitch and tolerance requirements.
- Production target: joints per shift or per day, and whether threading happens in a workshop or on site.
- Site services: available voltage, phase configuration, air demand and whether pneumatic tools are used.
- Mobility and handling: whether the machine stays fixed or moves between floors and buildings.
- Tooling scope: die sets, spare dies, cordless tool combination and battery platform.
- Delivery and documentation: destination, packing expectations and the documentation set required for handover.
Maintenance, Spare Parts and Technical Support
We supply spare parts across the product range and provide technical support and training for partners and operating teams, including demonstrations on Xinabo machinery. Dies, clamping fixtures and cutting blades are the wear items that determine thread consistency, so we keep them available as separate line items alongside complete machines.
Frequently Asked Questions
What pipe diameters and thread standards can Xinabo threading equipment handle?
The intelligent threading machine covers DN15–DN100, the SQ65 covers 15–65 mm and the SQ100 covers 15–100 mm. All three support British (BSPT) and American (NPT) threads, and the intelligent platform additionally handles Metric and customised non-standard threads with dedicated die heads.
How does an intelligent threading machine differ from a conventional electric pipe threader?
It identifies pipe diameter automatically and sets the tool without manual adjustment, then threads 15–25 mm pipe in as little as 4 seconds. Across an 8-hour shift it processes 1,500–2,000 threads, which reduces the labour required per joint compared with conventional threading.
Which materials can be threaded on your machines?
Carbon steel, galvanised steel, stainless steel, aluminium and copper pipe are all within the working range. Speed stage and die selection are set according to material and wall thickness, which is why the three-stage gear shank is used on the intelligent machine.
Do your cordless tools share one battery platform?
Our brushless cordless tools run on 16 V–21 V lithium-ion platforms, and the backpack battery pack at 20 Ah or 30 Ah powers multiple tools in sequence. This keeps a crew working along a riser or across a floor plate without returning to a charging point.
Are threading dies supplied separately from the machines?
Yes. Double-edged dies for intelligent threading machines and high-speed steel dies for electric threading machines are supplied as 4-piece sets in BSPT, NPT and Metric profiles, and can be ordered as replacement tooling independently of a machine purchase.
What do you need from us to prepare a configuration and quotation?
Send the pipe diameter range, material, thread standard, expected joints per shift, site voltage and phase, and whether the machine will be fixed or moved between locations. With that information we match the machine, die sets, cordless tool combination and delivery scope in a single proposal.
