Glass Syntactic Polyurethane (GSPU)
Glass Syntactic Polyurethane (GSPU) is a flow assurance insulation system for deepwater applications used for thermal management of subsea flowlines. The product is designed to perform at high-service temperatures and is an economical alternative to 5LPP.
About the Product
- GSPU is a reaction injection molding (RIM) product. System components are blended and injected into steel molds that surround the pipe’s outer surface.
- The product contains hollow glass microspheres (HGMS) to improve resistance to heat flow and are resistant to extreme crushing forces found at subsea water depths.
- GSPU is formulated to resist chemical breakdown in hot and wet service conditions that are typically found in subsea environments.
- GSPU delivers excellent thermal insulation, adhesion, impact strength and durability across a broad spectrum of demanding installation and operating conditions.
Bayou Wasco Facilitiy
- Modern and fully automated with minimal touch points between man and machine.
- Boasts a high speed insulation process that can produce three to five joints per hour.
- The plant’s advanced features allow for more precise control of pipe and mold temperatures, more accurate centering of pipe within the insulation, greater end-centering for improved field jointing, and 100% abrasion of FBE for superior adhesion.
