High Density Pipe Supports
PTU HDPUF Series — High-Density Polyurethane Systems
PTU supplies fully formulated high-density polyurethane (HDPUF) chemical systems used by manufacturers to produce rigid, load-bearing pipe supports for insulated piping systems.
HDPUF pipe supports are designed to transfer pipe loads while providing thermal insulation and helping to minimise thermal bridging at pipe support locations. Depending on the formulation and application, PTU HDPUF systems can be supplied for a range of target densities, typically from approximately 160 to 500 kg/m³, with formulations selected to meet the required mechanical, thermal and dimensional performance.
Pipe supports are commonly produced by moulding or can be machined or precision-cut from HDPUF blocks to suit specific pipe dimensions and support designs. PTU supplies HDPUF systems for demanding applications, including cryogenic service, where high compressive strength, dimensional stability and controlled thermal performance are required.
Selected PTU HDPUF systems are available for applications requiring performance in accordance with relevant CINI specifications for cryogenic pipe supports, including service conditions down to approximately −165 °C, subject to the specific formulation, support design and applicable qualification requirements.
Product Features
High Load-Bearing Performance
HDPUF systems can be formulated to provide high compressive strength and load-bearing capacity, supporting insulated piping systems under demanding service conditions.
Thermal Insulation Performance
The low thermal conductivity of suitable HDPUF formulations helps reduce heat transfer and minimise thermal bridging at pipe support locations.
Dimensional Stability
Formulations can be developed to maintain dimensional integrity under demanding temperature and loading conditions, supporting long-term performance of the finished pipe support.
Cryogenic Application Capability
Selected PTU HDPUF systems can be formulated and qualified for cryogenic applications, including low-temperature service conditions encountered in LNG and other industrial processes.
Controlled Leachable Halide Content
Where required, HDPUF systems can be formulated to achieve controlled low leachable halide levels, supporting corrosion-control requirements for applications where corrosion under insulation is a concern.
Application-Specific Formulation
PTU works with manufacturers and engineering partners to select and develop HDPUF systems to suit specific density, mechanical performance, temperature range, processing method and applicable industry requirements.
