PE Foam Pipe Insulation

Our Quality, Your Satisfaction

Insulation Foam Tube

Greenland’s Foam Tube is quality insulation tube of high-grade expanded polyethylene material with a closed cell structure obtained through direct extrusion. The process does not involve any (H) COFs and is therefore an environmentally friendly product.

The Foam Tube is highly flexible and light weight in nature Because of its mechanical properties and characteristics, it is highly suitable for chilled and hot water pipeline installations. It is also excellent in preventing heat loss from hot water pipelines and in preventing heat gain and condensation in chilled water and refrigerant pipelines. Greenland’s insulation tubes are highly cost effective and provide an excellent solution especially for central air conditioning ductwork insulations.

Characteristics and Advantages

  • Low Thermal Conductivity makes it a superb insulation material for cooling or heating systems
  • An Operating Temperature that range between -40°C to +80°C.
  • Lowest water absorption and vapour transmission. The dense cell structure provides an excellent vapour barrier for preventing condensation or frost formation on chilled water pipelines or refrigerant lines. It also retards heat loss for hot water pipelines and heating systems.
  • High resistance to most chemicals and which makes it ideal for protecting pipelines from corrosion by external atmospheric factor.
  • High flexibility and smooth surface of the Insulation Foam Tube

Installation and Application Recommendations

1. Pre-Assembling Line
Installation the insulation Foam Tube on the pipeline is fast and easy. To install, just insert and slip the insulation Foam Tube over the copper or iron pipe.

The installation Form Tube can be easily cut with a cutting blade and knife. To join the insulation Foam Tubes, apply a coat of adhesive glue to both butt ends. All the adhesive glue to set until non-tacky to the touch and then press the joints firmly together.
For a perfect finish, we recommend using PVC adhesive tapes or aluminium tapes on joints and seams.

2. For existing pipelines
To install the insulation Foam Tube on existing pipelines, just slit the tube lengthwise on one side and snap over the copper or iron pipe. Then seal the slit surface and butt joints with adhesive glue.

Wall thickness of insulation Tubes recommended to control condensation in pipe insulation of cooling lines.

In general, selection of the types of wall thickness of the insulation tubes largely depend on two main factors: the external weather temperature and atmospheric humidity conditions where the pipelines are installed.

i. Insulation under frequent low humidity and normal weather conditions (Weather Temperature of < 28°)

To maintain pipeline temperature Recommended wall thickness
> 5°C 10 mm ; 13 mm
< 5°C 19 mm ; 25 mm

ii. Insulation under frequent high humidity and high external weather conditions (Weather Temperature of > 28°)

To maintain pipeline temperature Recommended wall thickness
> 5°C 13 mm ; 19 mm
< 5°C 19 mm ; 25 mm
