Equal-Length Twin Stud – For Pressure Vessel Flange
Product Overview
Equal-Length Twin Studs are specialized fasteners used predominantly in applications requiring secure and consistent threaded connections, especially in high-pressure environments. Designed to maintain identical lengths on both threaded ends, these studs are ideal for connecting flanges in pressure vessels, ensuring uniform load distribution. The Equal-Length Twin Stud is commonly manufactured from high-strength alloy steel to meet stringent mechanical performance requirements in industrial applications.
As a leading manufacturer and global supplier, Flybear Fastener offers precision-engineered Equal-Length Twin Studs that conform to international standards. Our products are built for durability, corrosion resistance, and optimal performance in challenging working conditions.

Materials & Production Process
The Equal-Length Twin Stud is manufactured using premium-grade high-strength alloy steel, selected specifically for maximum durability and heat resistance. Common material grades include ASTM A193 B7, B16, or equivalent European standards. The production process involves:
- Material Selection & Cutting
- Thread Rolling or Cutting
- Heat Treatment for Mechanical Enhancement
- Surface Treatment (Galvanizing, Zinc Coating, etc.)
- Dimensional Verification & Quality Control
- Packaging & Labeling for Export
High-precision machining equipment and quality inspection systems are utilized to maintain tight tolerances and consistent thread quality.
Common Industries & Applications
Equal-Length Twin Studs are widely used across several high-demand sectors:
- Oil & Gas: Securing pressure vessel flange connections in offshore and onshore operations
- Chemical Processing: For aggressive media environments in chemical reactors
- Power Generation: In boilers, turbines, and pressure-based assemblies
- Shipbuilding: For marine-grade applications requiring corrosion resistance
- Refineries: In pipelining and transmission of hydrocarbons under high pressure
These threaded studs are critical components in environments where flange tightness affects safety and efficiency.

Quality Control & Inspection Process
Flybear Fastener maintains a multi-layered Quality Assurance System which includes:
- Raw material chemical & mechanical verification
- In-process dimension checks and thread gauge testing
- Final piece-by-piece inspection
- Salt spray and surface adhesion tests
- Certification in ISO 9001 and compliance with major international standards
Quality is built into every batch to ensure reliability under pressure.
Selection & Purchasing Guidelines
When selecting the right Equal-Length Twin Stud for your application, consider:
- Flange Pressure Class (150# to 2500# or PN10 – PN400)
- Material grade required by service conditions
- Thread pitch and diameter matching counterpart components
- Surface treatment based on environmental exposure
A correct match assures leak-proof and stress-resistant sealing of flange joints. Engineers should evaluate code requirements (like ASME Section VIII) for pressure vessels to ensure compliance.
Additional Product Considerations
Flybear Fastener also produces a wide range of stud bolts, hex cap screws, and heavy hex nuts compatible with ASME and DIN flange systems. For specialized applications, we offer coating solutions like PTFE, Xylan, or Cadmium plating. Customized packaging with part coding and batch tracking is also available upon request.
