Cold insulation pipe holder

Cold insulation pipe support is a supporting component used in low-temperature pipeline systems, mainly to reduce cooling loss, prevent pipeline condensation or frosting, and confirm the stable operation of pipelines in low-temperature environments. Here is a detailed introduction:

material

Cold insulation materials: Hard polyurethane, asphalt red pine wood, etc. are often used. Hard polyurethane has the advantages of good density, low thermal conductivity, low water absorption, and low temperature resistance. It can effectively reduce cold transfer and prevent condensation water from penetrating. Asphalt red pine also has definite thermal insulation and anti-corrosion properties (based on actual reports).

Outer protective material: Usually, a moisture-proof (based on actual reports) layer, such as aluminum foil, stainless steel sheet, etc., is wrapped around the outer layer of the cold insulation pipe support, or a corrosion-resistant (based on actual reports) coating is applied to enhance its performance stability and prevent external environmental erosion of the cold insulation material.

structure

Generally includes a base, pipe clamp, and insulation layer. The base is used to support the pipeline, separating it from the supporting structure and reducing the thermal bridge effect; Pipe clamps are used to secure pipelines and prevent displacement or shaking; The insulation layer plays a role in insulation and cooling, wrapping around the pipeline to reduce the loss of cooling capacity. Some specially designed cold insulation pipe supports may also have stainless steel thin plates and angle steels at the bottom, with polytetrafluoroethylene plates embedded in the rectangular grooves of the lower steel plates and fixedly connected to them to improve the compressive and bending resistance of the pipe supports.

function characteristics

Thermal insulation and cooling: Excellent in reducing the thermal bridge effect between pipelines and supporting structures, reducing the loss of cooling capacity, and preventing the surface temperature of pipelines from being too low.

Anti condensation: To prevent the accumulation of condensed water on the surface of pipelines due to temperatures lower than the dew point temperature of the surrounding air, and to protect pipelines and supports from corrosion.

Shock absorption and buffering: capable of absorbing pipeline vibration or stress caused by thermal expansion and contraction, reducing damage to pipelines and supporting structures.

Support fixation: Provide stable support for the pipeline, confirm that the pipeline maintains the correct position and posture at low temperatures, and prevent displacement or deformation.

Application scenarios

Liquefied natural growth gas (LNG) pipeline: During the storage and transportation of LNG, it is necessary to keep the natural growth gas at a relatively low temperature. Cold insulation pipe supports can effectively reduce cooling loss and protect the low-temperature state of LNG.

Freezing and refrigeration system: For low-temperature pipelines in cold storage and cold chain logistics, the use of insulation pipe supports can maintain the temperature of the low-temperature medium inside the pipeline, prevent the leakage of cold capacity into the surrounding environment, and reduce energy consumption.

Chemical low-temperature pipelines: Transport pipelines for chemical low-temperature media such as liquid nitrogen and liquid oxygen. Cold insulation pipe supports help maintain the low-temperature characteristics of the media and confirm the safety and stability of the chemical production process.

Air conditioning refrigeration system: The low-temperature water pipeline in the air conditioning system can reduce cooling loss, improve refrigeration efficiency, and prevent condensation on the surface of the pipeline by using insulation pipe supports.

Advantage

Excellent performance: For example, polyurethane cold insulation pipe supports have the advantages of good specific strength and low thermal conductivity, which can meet the cold insulation requirements well. At the same time, they have excellent chemical properties such as hydrolysis stability, aging resistance, and good acidity and alkalinity.

Beautiful appearance: The appearance is relatively neat, the overall effect is good after installation, and the installation operation is simple and convenient, which can improve construction efficiency.

Wide applicability: can be customized according to different pipeline diameters and application scenarios, suitable for various industrial pipeline systems, including low-temperature pipelines in industries such as petrochemicals, fertilizers, chemical fibers, pharmaceuticals, paper industry, steel, power plants, etc.
