" Thermal insulation wood cushion block factory Korean pine cold insulation wood block is mainly used to transport low-temperature medium The Conduit , if not Special materials If the pipeline is protected outside, the cooling capacity will be greatly lost during transmission, resulting in transmission failure. Therefore, special materials should be used for cold insulation of low-temperature transmission pipeline. Generally, it is popular to wrap the pipeline with Korean pine wood blocks for cold insulation. In addition, the support pipe bracket of the pipeline should also be made of Korean pine wood for cold insulation. In this way, the cold capacity of low-temperature pipeline will not be lost too much during the transportation process. Adopt advanced production equipment, and according to the standard pipe support drawing HG/T21629-1999 implemented and issued by the State Petroleum and Chemical Industry Bureau, it is used for fixed pipelines with oil, water and gas as the medium in mechanical hydraulic systems of metallurgy, petroleum, chemical industry, vehicles, ships, electric power, etc pipe clamp 。 DN10 to DN1000 can be processed

DN125 DN150 DN200 DN250 DN300 DN350 DN400 DN450
DN500 DN600 DN700 DN800 DN900 DN1000
Materials: domestic Korean pine, Russian imported Korean pine, New Zealand Korean pine and other Korean pine,
surface treatment : via asphalt The paint is soaked twice, which has the function of high and low temperature resistance and corrosion resistance.
Usage: It can effectively prevent the transmission of cold energy, produce cold bridges, and play the role of heat insulation/cold insulation/vibration reduction and thermal expansion mitigation.
Advantages: It is not easy to deform and crack after high temperature treatment, and the combined angle error is small.
Specification: DN10-DN1000
Thickness: 10mm-450mm
Angle: 40 ° - 360 °
Width: 10mm-450mm
Executive standard: HG/T21629-1999 (A13 J8 J9 E16, etc.)
Knowledge expansion and extension: the inner, middle and outer layers of the cold insulation layer should be made into many parts, and the circumferential and longitudinal joints should be staggered.
• All longitudinal and circumferential joints on the outer layer of PIR cold insulation materials shall be bonded or sealed with sealing materials.
• When the outer diameter of the equipment or the diameter of the cold insulation inner layer is less than or equal to 3600mm, the PIR material shall be made into curved plates or blocks. When the diameter is more than 3600mm, the plate shall be used.
• The external surface of PIR cold insulation layer shall be coated with glass fiber mesh cloth reinforced moisture-proof mastic.
• The longitudinal and circumferential overlapping width of metal protective layer shall be 50mm, and the overlapping part is used for drainage. Cleaning of surface cooling, heating, humidifier surface, inner surface of condensation tray, and return air inlet: cleaning of surface cooling, heating, humidifier, and return air inlet can not only improve air quality, but also have a strong energy-saving effect. The common cleaning method is to use air injection cleaning agent, and then purge with high pressure or air, so that the dirt can be quickly dissolved and purged, and then rinse with low pressure.
