Product Datasheet of Sealing Strip S1GA4660W01

ꁆ ꁇ

Product Overview

The Sealing Strip S1GA4660W01 engineered from premium closed-cell foamed rubber. It serves as a specialized sealing and vibration-damping component for the flanges and casings of FAF and PAF type moving-blade adjustable axial flow fans, including primary air fans, forced draft fans, and induced draft fans in power plants.

Commonly applied to casing split lines, manhole doors, maintenance hatches, flange connections, and shroud areas, this strip is a standard configuration consumable for power plant maintenance and axial fan overhauls.

Technical Features & Advantages

Closed-Cell Structure: High-quality rubber with independent, closed pores (approx. 8% density). It is non-absorbent and airtight, effectively blocking water, dust, wind, and smoke.
High Resilience & Anti-Compression: Excellent elasticity allows the material to maintain its shape under long-term vibration and thermal cycling, ensuring a persistent seal during fan start-stop or load fluctuations.
Weather & Temperature Resistance: Resistant to aging and ozone. It will not become brittle, powderized, or detached under fluctuating temperatures, meeting the requirements for continuous long-term operation.
Precision Engineering: Standardized dimensions facilitate quick installation. It can be easily cut to fit various sealing surfaces, significantly reducing downtime during maintenance.

Integrated Sealing System Compatibility

The S1GA4660W01 works in synergy with other FAF/PAF fan components to form a comprehensive pressure-containment system.

Complementary Components Table

Component Name	Model/Dimensions	Fitting Location	Synergistic Effect
Sealing Strip	S1GA4660W01	Casing flanges, manholes, shrouds	Primary seal; prevents wind/dust/smoke leakage.
Sealing Shroud	850010020mm	Outer periphery of impeller	Works with the strip to form a circular seal.
Positioning Sleeve	4TY5026 / S4GA0260	Blade adjustment mechanism	Ensures uniform gaps to optimize sealing.
Tension Spring	4TY9515 / S4GA0307	Shroud and slider mechanism	Provides pre-tightening force for a tighter fit.
Slider	4TY0432 / 4TY0431	Moving blade adjustment	Stabilizes operational clearance; reduces wear.

Induced Draft Slider	S4GA3053	ID Fan adjustment mechanism	Improves operating conditions; extends seal life.
Check Valve	S20A1.0	Hydraulic oil station	Ensures oil system stability; reduces failure risk.

Application Scenarios

1. Fan Casing Split Line

Used for the joining surfaces of the upper and lower casings and the diffuser. It fills machining and assembly gaps to prevent air leakage and improve fan efficiency.

2. Manholes and Maintenance Doors

Installed on flange faces of access doors to block dust and airflow while providing a vibration-buffering effect to protect the door frames.

3. Shroud-to-Casing Clearance

Used in conjunction with the sealing shroud to fill the gap between the impeller periphery and the casing, reducing "short-circuit" airflow and increasing economic efficiency.

4. Flange and Duct Interfaces

Replaces traditional asbestos materials at inlet/outlet flanges. It is environmentally friendly (dust-free), provides more uniform sealing, and offers a longer service life.

5. Routine Maintenance and Overhauls

As a standard "wear part" for FAF/PAF fans:

Minor Maintenance: Inspect for aging, crushing, or damage.
Major Overhaul: Full replacement to restore the sealing system to optimal factory performance.

Conclusion

The S1GA4660W01 Sealing Strip is a cost-effective, high-versatility core consumable. By choosing this reliable spare part, power plants can significantly reduce fan leakage rates, lower energy consumption, and ensure the safe, long-cycle operation of the air and flue gas systems.
