Supply details of high-density polyethylene insulation pipe

Since the birth of polyurethane synthetic materials in the 1930s, it has been rapidly developed as an excellent thermal insulation material, and its application scope has become increasingly wide. Due to its simple construction, energy-saving and anti-corrosion properties, it has been widely used in various heating, cooling, oil and gas pipelines.

Supply details of high-density polyethylene insulation pipe

It mainly consists of four parts.
（1）Working steel pipe: Welded steel pipes are used according to the technical requirements of the conveying medium,seamless steel pipe,Double sided submerged arc spiral welded steel pipe.
（2）Thermal insulation layer: rigid polyurethane foam.
（3）Protective shell: Made of high-density polyethylene or fiberglass.
（4）Leakage alarm line: When manufacturing high-temperature prefabricated buried insulation pipes,In the insulation layer near the steel pipe,Buried with alarm lines,Once there is a leak in a certain part of the pipeline,Through the transmission of alarm lines,It can alarm and display the accurate location and degree of water leakage on the detection instrument,In order to notify maintenance personnel to quickly handle the leaking pipe section,Ensure the safe operation of the heating network.

feature
Polyurethane insulation pipe has a light bulk density,high strength,adiabatic,sound insulation,flame retardant,cold-resistant,anticorrosion,waterproof,Excellent features such as simple and fast construction,Has become a building,transportation,petroleum,chemical industry,electricity,Insulation and heat preservation for industrial sectors such as refrigeration,Waterproof and leak proof,Materials for sealing, etc. waterproof,anticorrosion,Enduring aging:Because the closed cell ratio of polyurethane foam reaches92%above,Therefore,Use polyurethane foam as insulation layer of directly buried pipeline,Not only can it provide insulation and heat preservation,And it can effectively prevent water leakage,Moisture and other corrosive liquids,Permeation of gas,Prevent the growth and development of microorganisms. Polyurethane insulation pipe with its excellent performance,Convenient construction and long service life are highly welcomed by people.

Stacking and storage of pipes
1.The storage site for pipes should be flat, free of debris, stagnant water, and have sufficient load-bearing capacity.
2.The pipe should be placed 2 meters away from the heat source and equipped with fire-fighting facilities.
3.Stacking pipes must be cushioned with pipe pillows; The width of the pipe pillow should be greater than 150mm, and the height should be greater than 100mm. When storing pipes of the same type, they should be placed together, and 12m long pipes should be placed in whole pieces layer by layer from the ground. Short term stacking of each layer may not require the placement of whole blocks, but the height must not exceed 1.5m
4.During the storage period of the pipe material; Both ends of the steel pipe should be sealed, and when stored outdoors, it should be covered with felt cloth. Sun exposure and rain are prohibited.
5.When lifting pipes, a sling with a width greater than 50mm should be used for lifting.
6.During loading and unloading, it is necessary to handle with stability and care to prevent collisions.
7.When unloading, vertical lifting should be used for car transportation, and forklifts and loaders can be used for container transportation. Lifting is strictly prohibited from using iron tools to pry or steel wire ropes to directly bind the outer sleeve.
