PRODUCT DESCRIPTION
Our Split Collar Nut, crafted from premium stainless steel 316, is a high-performance fastening solution designed to excel in critical environments. Combining advanced manufacturing techniques with rigorous quality control, this product delivers exceptional precision (±0.05mm), durability, and corrosion resistance, making it ideal for applications in pipelines, pressure vessels, refrigeration systems, and fluid/gas transport infrastructure.
Key Features
- Superior Material: Stainless steel 316 ensures outstanding resistance to corrosion, high temperatures, and harsh chemicals, guaranteeing longevity in demanding conditions.
- Precision Machining：
- Step 1: CNC machining centers transform round steel bars into perfectly dimensioned equilateral octagons.
-Step 2: CNC lathes meticulously craft internal bores, threads, and sleeves with micron-level accuracy.
- **Step 3**: Hydraulic presses assemble inner and outer sleeves seamlessly for a secure, interference-free fit.
- Step 4: Flared mouth expansion via precision molds ensures optimal grip and load distribution.
- Flawless Finish: Mirror-smooth surfaces free of burrs or imperfections minimize friction and prevent contamination.
- Rigorous Tolerances: ±0.05mm dimensional consistency guarantees reliable performance under high stress and vibration.
Technical Specifications
- Material: Stainless Steel 316 (ASTM A276)
- Thread Standards: Customizable to ISO, ANSI, or client-specific requirements
- Surface Finish: Ra ≤ 0.8 μm
- Temperature Range: -50°C to 800°C (short-term)
- Pressure Rating: Up to 10,000 PSI (dependent on configuration)
Primary Applications
- Pipeline flange connections
- Pressure vessel sealing systems
- Refrigeration compressor assemblies
- Hydraulic/pneumatic fluid transfer units
- Chemical processing equipment
Quality Assurance
Every nut undergoes 100% dimensional inspection via CMM and visual defect screening. Certificates of Conformance (CoC) with traceable heat numbers are provided upon request.
Why Choose Our Split Collar Nut?
- Proven Reliability: Optimized for leak prevention and long-term structural integrity.
- Customization Ready: Modify dimensions, threading, or flaring angles to match your exact specifications.
- Cost Efficiency: Reduced maintenance needs and extended service life lower total ownership costs.
