STYLE 2236

Flexible Graphite with Inconel Wire, Low Emission

Description and Application

Teadit® 2236 valve packing is self-lubrificating, non-hardening, dimentionally stabe and resistant to gases and fluids as well as heat, pressure and chemicals. It's high temperature flexible graphite and Inconel® filament jacket affords mechanical stability while the advanced construction provides leakage control and high integrity in steam service. Due to its physical properties and ability to minimize friction. Teadit ® Style 2236 is ideal for valves and can be used within a broad range of applications.

International Approvals* for 2236

Tests conducted by Yarmouth Research and Technology Maine – USA

Fire Test

Objective

Qualify packing Style 2236 for fire resistance when applied to valves subjected to direct flame.

Test Procedure

API STANDARD 607 — SIXTH EDITION

Conclusion

Packing 2236 has successfully completed the test reaching comfortably the requirements of this standard.

Fugitive Emission Test

Objective

To qualify packing style 2236 for low fugitive emissions in valves when subjected to thermal and mechanical cycles. Leak detection method "EPA method 21".

Test Parameters

5 thermal cycles at room temperature and up to 260°C. Leak measurements performed before and after each thermal cycle and every 100 cycles of the stem.

Test Pressure: 600 psig (42 Kgf/cm2).

Conclusion

Packing 2236 presents the best results in fugitive emissions control averaging 2 PPMv without any adjustment of the gland and it outperformed all competitors in test performed in the Yamouth Research and Technology, in Maine/USA, as shown in the graphs below.
