galvanized jacketed pre-insulated steel pipe
Here are some details about galvanized jacketed pre-insulated steel pipe:
Construction: It consists of a steel pipe surrounded by insulation (usually polyurethane foam), which is then encased in a galvanized steel outer jacket.
Galvanized Jacket: The zinc coating on the exterior steel jacket protects it from corrosion. Galvanizing increases durability for underground use where the pipe would be exposed to soil moisture and minerals.
Insulation: Polyurethane foam insulation provides efficient heat retention/transfer prevention. Its closed-cell structure makes it water resistant as well.
Joints: Adjoining sections are joined using insulation joint kits to maintain a continuous thermal break. Special coated fittings allow for connections.
Applications: Commonly used for underground hot and cold water distribution systems, geothermal piping networks, and structural pre-insulated foundations.
Advantages: Pre-insulated pipe provides protection from corrosion, insulation to maintain temperatures, and a factory-applied system that speeds installation.
Sizes: Typically available in diameters from 1-1/4″ to 24″ to accommodate varying flow rates/capacities as needed.
Standards: Must meet ASTM standards for material properties and performance of the steel, insulation and protective jacket.
So in summary, galvanized jacketed pre-insulated steel pipe is a durable, efficient piping solution for temperature-sensitive underground distribution systems. The zinc coating and polyurethane insulation provide protection and performance.
