Key features

The two-step method has a relatively mature production process, ensuring stable and reliable product quality.

The rigid polyurethane foam with a density between 60kg/m3 and 80kg/m3provides excellent thermal insulation performance.

The materials have a certain bonding strength, ensuring that the steel pipe, outer sleeve and thermal insulation layer form a solid whole.

Suitable for thermal insulation and cold preservation projects in heat supply, cooling, hot oil transportation, chemical industry and other industries.

The high-density polyethylene outer protective layer protects the insulation layer from mechanical hard objects and provides anti-corrosion and waterproof performance.

Product Q&A

Q:What is the processing range of your two-step method insulation pipe?

The processing range of our two-step method polyurethane prefabricated direct-buried insulation pipe is DN15mm-DN500. This wide range covers most common pipe diameters used in district heating, cooling, hot oil transportation and chemical industry projects. For special diameters outside this range, please contact us for further discussion.

Q:What is the thickness of the HDPE outer protective layer? Can it be customized?

The thickness of the high-density polyethylene outer protective layer can be customized according to your project requirements. The typical thickness ranges from 2mm to 10mm, depending on the pipe diameter, burial depth, soil conditions and mechanical protection requirements. The HDPE outer protective layer plays a key role in protecting the polyurethane insulation layer from mechanical damage and providing anti-corrosion and waterproof performance.

Q:Can you provide pipe fittings such as elbows, tees, reducers and flange joints?

Yes, we can provide various pre-insulated pipe fittings including elbows, tees, reducers, flange joints and fixed supports. These fittings are also produced with the same three-layer structure: working steel pipe, polyurethane insulation layer and HDPE outer protective layer. The fittings can be customized according to your pipeline design and installation requirements. Please provide your fitting drawings or specifications for accurate production.

Q:Do you provide installation guidance or technical support?

Yes, we can provide installation instructions, technical drawings and online technical support. For large projects, we can also arrange engineers to provide on-site installation guidance if required. Our technical team can assist you with pipe laying, joint insulation, leak detection and system commissioning. Please contact us for more details about our technical support services.
