Insulated Pipe They can be seen everywhere in daily life and concern every household. We may not purchase them privately, but they are always around us. Insulated steel pipe is a steel pipe with thermal insulation performance. So in practice, what are the advantages and disadvantages of insulated steel pipes? When we decide to purchase insulated steel pipes, which aspects can we consider in making a selection?
What is insulated steel pipe? It is steel pipe processed with insulation technology so that, under different working environments and external media, the internal and external temperatures of the carrier pipe meet service requirements.
What are the advantages of insulated steel pipe? Cathodic protection of direct-buried insulated pipelines is one of the electrochemical protection methods in metal anti-corrosion technology. Unlike other anti-corrosion techniques for direct-buried insulated pipe, a current is applied to the protected metal so that its electrode potential shifts negatively, reducing the metal's spontaneous tendency to go from the atomic state to the ionic state, thereby suppressing corrosion at the source. This process must take place in an electrolyte, so cathodic protection is very suitable for buried steel pipelines.
In addition, what are the disadvantages of insulated steel pipes? Cathodic protection of direct-buried insulated pipes and the anti-corrosion coating itself are complementary. The presence of the anti-corrosion coating can greatly reduce the current consumed by cathodic protection, and cathodic protection can make up for insufficient integrity of the anti-corrosion coating, thereby achieving a combination of safety and economy.
Tips for selecting insulated steel pipe: High-temperature prefabricated direct-buried insulated pipe is a prefabricated direct-buried insulated pipe with good thermal insulation, safety and reliability, and low cost. It effectively solves the insulation, sliding lubrication, and waterproofing of exposed pipe ends of 130—600℃ direct-buried prefabricated insulated pipe in urban district heating. High-temperature prefabricated direct-buried insulated pipe not only offers advanced technology and practical performance that traditional trench and overhead laying cannot match, but also delivers significant social and economic benefits. It is also an effective measure for energy saving in heat supply.
Two key points of insulated steel pipes: The rigid PU foam insulation layer is tightly bonded to the outer surface of the steel pipe and can isolate the penetration of air and water. At the same time, the foam cells are closed and water absorption is very low. The HDPE jacket and FRP jacket have good anti-corrosion, insulating, and mechanical properties. Therefore, the outer surface of the carrier pipe is difficult to corrode by external air and water.
Related decoration personnel indicate that in the process of house decoration, the selection of insulation materials is a very important step, as it relates to the quality of our future life. In today's market, where there are more and more insulation materials, take insulated steel pipes as an example. Tips for selecting insulated steel pipes can refer to the above introduction.
