In today’s era of advanced industrial sealing technologies, seal rings with spring‑energized systems stand as essential solutions across numerous sectors. Central to their sealing effectiveness is the H‑type spring. This article focuses on the Φ10 mm helical spring specialized for PTFE Energized Seals , providing an in‑depth exploration of its design, materials, performance, and applications. By unveiling how this compact component enables high‑reliability sealing, this guide empowers you to make superior decisions in device selection and seal system design.
This article presents a comprehensive look at the Φ10 mm helical spring for seal rings, covering:
Its precise flat‑ribbon helical winding structure that delivers high load per deflection and uniformly distributes load across the sealing surface;
Diverse material options, including 17‑7PH stainless steel spring 와 함께 PTFE jacket, tailored for complex working conditions;
Its robust operational capabilities: dynamic load up to ~20 MPa, static load above ~60 MPa, reciprocating speed up to 5 m/s, rotational speed ~0.1 m/s및 operating temperature range –200 °C to 260 °C;
Wide industrial applications such as semiconductor, automotive, chemical, and aerospace sectors;
Rigorous quality controls and customized services to support industrial sealing needs.
1. Ingenious Structural Design and Outstanding Performance
The H‑type helical spring uses a flat-ribbon helical winding, conferring significantly higher unit load compared to conventional coil springs. This structure permits limited deflection while providing strong support.
Under high-pressure conditions, the helical wound spring establishes a circumferential stress‑closed loop, uniformly distributing load across the sealing face—ideal for face sealing and static high-pressure scenarios.
In high-pressure valves, a Φ10 mm helical spring can maintain sealing integrity under extreme pressures up to ~68.6 MPa (700 kg/cm²), especially when paired with a back-up ring.
2. Material Options for Complex Working Conditions
스프링 재질: 17‑7PH stainless steel offers excellent corrosion resistance and high strength, delivering stable elasticity in chemically aggressive and thermally variable environments.
Jacket Material: Pure PTFE provides ultra‑low friction, excellent chemical inertness, and superior thermal tolerance. PTFE remains flexible and sealing-effective under extreme cold and is chemically non-reactive barring a few rare substances—making it ideal for demanding seals.
3. Excellent Operational Performance & Addressing Industry Benchmarks
작동 압력: Dynamic load capacity ~20 MPa, static load up to 60+ MPa—on par with industry seals such as those from SEALS (dynamic ~20 MPa, static ~80 MPa).
Motion Velocity: Supports reciprocating up to 5 m/s and rotational up to 0.1 m/s. While sensitive to eccentricity, in these speed ranges it ensures stable sealing and compensates for wear and misalignment.
Internal industry data confirms that helical springs are best suited for static or very slow‑dynamic applications due to their small deflection range but strong sealing capabilities.
온도 범위: –200 °C to 260 °C enables use in extreme cold (e.g., LNG handling) and high‑temperature environments (e.g., reaction vessels).
4. Broad Industrial Applications
반도체: Vital in high-purity gas delivery lines—helical springs maintain seal, resist fatigue and corrosive gases, and handle low-temperature operations.
자동차: Ideal for fuel injection, hydraulic control systems—withstanding temperature fluctuation, pressure cycles, and vibration to prevent leaks and preserve safety.
화학 처리: Excellent chemical resistance and high-pressure capability make these springs effective in violent or corrosive chemical pipelines.
항공우주: In hydraulic and fuel systems exposed to extreme altitudes and temperatures, Φ10 mm helical springs ensure reliable sealing under stringent conditions—consistent with their use in cryogenic and vacuum environments.
