First of all, what is insulated steel pipe?  

It is a steel tube that is insulated and treated under the interaction of different environments and external media.  In order to ensure that the internal temperature and surface temperature of the working steel pipe to meet the requirements.  

What are the advantages of insulated steel pipe?  erw welded pipe manufacturers- GKSTEELPIPE

The cathodic protection of directly buried insulation pipe is a kind of electrochemical protection method in the process of metal anticorrosion, which is different from other directly buried insulation pipe anticorrosion technology.  By applying a current to the metal body, the electrode potential of the metal body can be protected from negative movement.  This is the transition from atomic state to ionic state of the metal medium, forming a spontaneous trend.  It fundamentally controls the generation of decay, but the process is carried out in an electrolyte, so it is very suitable for cathodic protection directly embedded in steel tubes.  

 What is the role of insulated steel pipe?  

First of all: prefabricated directly buried thermal insulation pipeline is a kind of prefabricated pipeline with good thermal insulation performance, safe and reliable, low project cost and more conveying medium.  Its emergence solves the sliding lubrication and waterproofing problems of bare pipe ends with high temperature of 130℃-600℃ in urban district heating.  High temperature prefabricated directly buried insulation pipe has advanced technology and practical performance.  Compared with traditional ditches and overhead pipes, insulated steel pipes offer significant social and economic benefits, as well as being a powerful means of heating and energy saving.  

Second: the polyurethane foam insulation layer is close to the outer layer of the steel pipe, which not only isolates the air, but also isolates the water penetration.  The bubble is closed, the water absorption rate is small, and it has good anti-corrosion effect.  At the same time, the polyethylene shell and the glass fiber reinforced plastic shell have good anti-corrosion, thermal insulation and mechanical properties.  Therefore, the outer surface of the working steel pipe is not corroded by air and water vapor, thus prolonging the service life of the pipe.  

Third: Insulated steel pipe can not only drain water in time, but also serve as a signal reminder for daily operation.  Pipeline thermal compensation shall be done using a high-quality bellows compensator that is installed in the casing to form a direct embedded form without the need for an observation well.  In addition, the construction is convenient, the construction period is short, suitable for conveying 2.5MPa below 350℃, steam or other media!  With steel tube as the outer protective layer, the product has the advantages of high strength, not easy to damage, simple construction and maintenance, and long service life.  

There are a lot of insulated steel pipes, but how much do you really know?  I believe that through reading the above content, everyone will have a better understanding of the insulation steel pipe.  That's all for today, please stay tuned for more knowledge!
