This product is a hollow full-thread external joint (also known as: hollow external thread sleeve, full-thread connecting pipe), featuring a full external thread wrapping + hollow through-structure design:
The outer surface is equipped with high-precision threads, allowing direct screwing into internal threaded interfaces (e.g., valves, pipe fittings, equipment bases)
The internal hollow channel supports fluid transmission, cable threading, or structural connection without media, enabling the integration of "connection + functional channel"
Pipe threads: G is a parallel pipe thread (requires a sealant); NPT is a tapered pipe thread (self-sealing, suitable for high pressure)
Metric threads: Designed for mechanical structural connections, with a thread tolerance class of 6g
Custom Dimensions
Length: L=10-100mm (standard: 15/20/25mm); outer diameter: D matches the thread; inner diameter: d=D-2*wall thickness (wall thickness: 2-5mm)
The hollow inner diameter can be customized (e.g., larger diameters for cable threading), and the wall thickness ensures tensile strength (≥200MPa)
Surface Treatment
Stainless steel mirror polishing (Ra≤1.6μm), blue-white zinc/plated color zinc for carbon steel
Enhances corrosion resistance and aesthetics. Stainless steel can be customized with passivation, nickel plating, or other special treatments
Application Scenarios
Fluid Engineering
Plumbing systems: Connects faucets and angle valves (G thread + PTFE tape to prevent leakage)
Industrial pipelines: Transmits chemical fluids (316 stainless steel) and beverages (304 stainless steel, food-grade), with the hollow structure ensuring unobstructed media flow
Mechanical Assembly
Structural connections: Used for machine tool bases and brackets (M thread, with hollow channels for hydraulic pipes/air hoses)
Vibration environments: Full-thread engagement provides strong vibration resistance, replacing welding for easy disassembly and maintenance
Electrical Wiring
Cable threading sleeves: The hollow channel routes cables, while external threads secure the component to equipment enclosures (e.g., control cabinets, sensor bases), integrating connection and wiring functions
Key Advantages
Dual-function of "connection + channel": Unlike traditional external threads (which only connect), this product's hollow design enables simultaneous media/cable transmission, reducing system complexity
Precision thread guarantee: Utilizes a thread-rolling process for full, uniform thread profiles and strict tolerances (100% inspection with go/no-go gauges), ensuring compatibility with both imported and domestic internal threaded components
Multi-scenario adaptability: Supports dual systems (pipe threads for fluids, metric threads for structures) and materials (stainless steel/carbon steel), meeting needs from civil applications (plumbing) to industrial settings (chemical engineering)
