Pre- Insulated Pipe & Manufacturing

BUSINESS > Pre-Insulated Pipe & Manufacturing

Definition

Pre-insulated pipe systems provide the safe and efficient method of transporting various fluids while minimizing heat loss. The factory prefabricated and pre-insulated pipe systems offer an energy efficient solution for a wide range of applications, especially for the carrying of fluids (hot water, steam and other high/low temperature mediums) to the users. This system has many experiences in combined heat and power plants of Korea District Heating Corporation.

Features

1. EXCELLENT THERMAL INSULATION

Polyurethane filler is light, impervious. It¡¯s thermal conductivity is very low, which shows superior thermal insulation characteristic. It is commercially available on the market. When pipe(500A), in district heating, carries hot water(120¡É) 40km away, the temperature drop is less than 2¡É.

2. SUPERIOR DURABILITY

3. OUTSTANDING ECONOMIC EFFICIENCY

4. VARIOUS SELECTION OF PORDUCTS

5. PIPE CLASSIFICATION

- For freeze prevention & general insulation

- For district heating

- For steam line (below 180¡É)

- For self heating

Material Specification

Insulation Material : Rigid-Polyurethane Foam

Casing Pipe : HDPE for underground, Aluminum (spiral wound) for above ground

Thickness of carrier and casing pipe depends on the conditions of fluid.
