What are the advantages of insulating supports?
1. Good protection performance. No damage to the main anticorrosion layer and insulation layer.
2. Good dielectric properties. The insulation between the main pipe and the sleeve is isolated to protect the cathodic protection system.
3. Good heat insulation performance. The heat conduction of the metal support is eliminated, the insulation layer and the decay layer are not damaged, and the energy consumption of the pipeline is reduced.
4. High chemical stability. Anti-oxidation, acid, alkali, no oil and oil.
5. Easy construction and installation. This product has small friction, light weight, lubrication and drag reduction, easy to pass through the casing, uniform force and so on.
Detailed explanation of the use of pipe insulation support range
1. Product Introduction:
Our company develops and produces "casing tube insulation support block" and "casing terminal seal" and other public engineering pipeline accessories, mainly used in natural gas, petrochemical, electric power, metallurgy, chemistry, and public utilities affiliated gas supply and drainage supply and distribution system pipeline transportation "Pipeline Crossing Construction Code".
This product has the following advantages over iron products:
1, good protection performance, no damage to the main anticorrosion layer, insulation layer.
2, good dielectric properties, is the insulation isolation between the main pipe and the casing, has a protective effect on the cathodic protection series.
3, good heat insulation performance, eliminate the heat conduction of the metal support, do not damage the insulation layer, anticorrosive layer, reduce the energy consumption of the pipeline.
4, high chemical stability, oxidation resistance, acid, alkali, inorganic salts and oil.
Easy construction and installation. This product is small friction, light weight, lubrication drag reduction, easy to pass through the casing, uniform force, etc.
Installation instructions for insulation support block in casing
1. The pipe insulation support spacing is determined according to the thickness of the pipe wall and the conveying medium, and the general support spacing is 1.5-2.0 meters.
2. Two groups of supports shall be installed side by side through the main end (1 meter inside the casing), and the middle distance shall be evenly installed according to the design requirements. Two sets of supports are installed side by side through the main end (1 meter inside the casing).
3. When the casing is steel casing, according to the requirements of construction technology, if the length of the casing is more than 80 meters, the pipe in the casing can be used to cross the guide block through the front end. When the main pipe crosses out of the casing, the pipe can be reused after being dismantled through the guide block.
4. When the casing is concrete casing, the crossing length is more than 30 meters. In order to prevent excessive wear of the insulation support block, the front end of the main crossing is added with the pipe in the sleeve to cross the guide pulley.
5. Each piece of insulation support block in the tube is equipped with insulating adhesive board of 3mm thick to meet the technical requirements of pipeline construction. During construction and installation, no additional adhesive board is needed, only each insulation support block needs to be connected with matching bolts. Bolt empty stroke can be used to adjust the insulation support block and the main tightness. Each piece of insulation support block spacing evenly arranged on the surface of the pipe body, fastening bolts can be.
