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.

Pre-Insulated Pipe and Fittings

Pre-Insulated Pipes • Heat loss during transfer is at a minimum level. • Provides ease of use, transportation and assembly. • It is resistant to corrosion. • It has a lifetime of more than 50 years under 120 ° C continuous temperature. • Due to the heat conduction coefficient of the polyurethane used, there is less heat loss compared to the classical system.Because the sheath pipe is HDPE, it provides 100% sealing.
