Product Description
PRODUCT DESCRIPTION
LYR2150 High Density Polyurethane Foam (HDPF) polyurethane hard foam plastic is used to fill the joints (field joint) of the underground pipeline, to help protect the joints and make the joints with a diameter similar toto easily move through the tube roller tube when sprayed.
The material most commonly used by G-TECH is LYR2150. It is a custom-designed high density polyurethane foam (HDPF) with a typical moulded density between 90 kgs per cubic metre (Cellafoam - 150/6) and 160 kgs per cubic metre (Cellafoam - 150/10) un-saturated.
Formulated specifically for pipeline field joint applications, the LYR2150 system develops a rigid, open cell structure. Upon immersion, the open cells will absorb water, thereby increasing in overall density to approximately 1025 kgs/m3 (similar to seawater itself).REQUIREMENTS SPECIFICATION
Feature
• No heat sources are necessary
(process at ambient temperatures)
• Commercially attractive
• Rapid cycle times
• Re-usable or expendable / disposable
(metallic or plastic) mould systems
• Compact, reliable application
equipment
• Compatibility with all conventional
anti-corrosion field joint coating systems
• ODP - zero category formulation
(no ozone damaging CFC solvents)
• Water blown
• No solvents required - all equipment
is air-purged
• A range of foam densitys are available
(6-10 lb / cu ft) typically
