SEALING GLAND SEALS 80 WIRES

Industry: Pump Assembly
Application: Testing of Feed Water Pumps

Customer Requirement:
The Westinghouse Pump Assembly Facility needed a sealing gland capable of sealing 80 Teflon-insulated, 24 AWG, Type j thermocouple wires (40 pairs) in nitrogen gas at 3750 psi and 205°C. The customer required the performance of hydrostatic pressure test at 3750 psi and 70°F for 10 minutes with no visible leakage or wire movement permitted. A certificate of conformance was also required.

Conax Design Solution:
Conax used its new MHM6 sealing gland with a Grafoil sealant. The assembly contained 120" leads on the body side. The Conax description is MHM6-24T(J)-A80-G, 120"/24". The customer said that Conax was the only vendor capable of sealing 80 wires for this high pressure application.
