As a specialized manufacturer based in Shanghai, Shanghai Quanbao Electronic Materials Technology Co., Ltd. delivers precision-engineered Industrial Grade Double Ferrule Tube Fittings designed for critical oil and gas operations. Our fittings ensure zero-leak performance in high-pressure transfer systems, reducing downtime and maintenance costs. With over a decade of expertise in fluid handling solutions, we provide reliable components that meet stringent industry demands for safety and efficiency.
The core innovation lies in the dual-ferrule mechanism which creates a permanent, vibration-resistant seal:
- Front Ferrule: Forms a radial grip on the tube
- Back Ferrule: Applies axial force for mechanical strength
- Gas-Tight Seal: Achieved through cold flow deformation
Technical specifications include:
| Model Series | Pressure Rating | Tube Compatibility |
|---|---|---|
| QB-DF6 | 3000 psi (206 bar) | 1/8"-1/2" |
| QB-DF8 | 5000 psi (345 bar) | 1/4"-2" |
Key advantages for operators:
- Eliminates fugitive emissions in sour gas service
- 30% faster installation than flare fittings
- Reusable up to 3 cycles without performance loss
- Resists hydrogen embrittlement in H2S environments
Shanghai Quanbao's ISO-compliant manufacturing facility utilizes CNC machining with dimensional tolerances within ±0.01mm. Each fitting undergoes helium leak testing at 1.5x working pressure. With 98.7% on-time delivery rate to global energy clients, we offer technical support for custom configurations including NACE MR0175 compliant options.
