PROCAST PFP Casting Systems
Jurunature Sdn Bhd manufactures it’s our proprietary PROCAST PFP CASTING systems. This are removable PFP casting for items such as valves and flanges and any equipment that requires inspection and maintenance.
As the castings are fully removable, and reusable, maintenance and inspection of the items can be carried out with little inconvenience. Where wet application is used, PFP cast access boxes can be fitted to pipes, vessel body and other structure, to allow inspection for under insulation corrosion etc.
The pictures demonstrate the process for the Procast PFP castings for the Helang and Talisman project. These castings are individually designed after site stringing, to determine size and shape requirements needed to fit local situation. When practical, foam cut-outs are used first as trial fit items for the Procast PFP castings before making the castings. The Procast PFP castings are reinforced with steel or metal mesh at the mid DFT thickness point, which extends all the way into the flanges.

The PFP material also provides insulation and blast-proofing properties.
