Description

The PC20 range of pipeline connectors are designed to give universal flow direction when used with the following swivel connector steam traps: UTD26, UTDM42, UTD52, UBP21, UBP32, UFT14, UFT32, UIB30 and UIB30H.

The integral strainer screen provides protection for the selected steam trap where system conditions require. There is an optional blowdown valve which can be used to periodically remove any pipeline debris.

The PC20 can also be supplied fitted with an integral Spiratec sensor to detect steam trap failures and reduce energy costs. These are designated IPC20 and IPC21. Full details are on TI-P128-17.

Safety information, installation and maintenance

For full details see Installation and Maintenance Instructions (IM-P128-11) supplied with the product.

General information

There are two criteria which must be satisfied to ensure that the swivel connector trap will operate correctly and ensure effective condensate removal:

1. The PC20 shall be installed with flow in the direction of the arrow. Flow can be horizontal (either direction), vertical or inclined.
2. The connection face for the swivel connector steam trap must always be in the vertical plane unless stated on relevant steam trap Installation and Maintenance Instructions.

After installation it is recommended that the pipeline connector is insulated to minimise radiated heat losses and to protect personnel from burns risk. Note: Ensure that the discharge from the blowdown valve blows to a safe place. Detailed instructions regarding welding socket weld versions are provided with the product.

Disposal

The product is recyclable. No ecological hazard is anticipated with disposal of this product providing due care is taken.

How to order
