In some oil, gas, central air-conditioning ventilation pipes, often use the thermal insulation steel pipe. So, what is the quotation of the thermal insulation steel pipe? In this article, I will give you a brief introduction to the relevant knowledge of the insulation steel pipe, including the insulation steel pipe quotation.
Insulation steel pipe advantages
Insulation steel pipe, is the internal temperature and surface temperature can reach the use of the requirements of the steel pipe, it is processed through the insulation process. The advantages of heat insulation steel pipe include robustness, not easy to damage and erosion, reduce heat loss, good sealing, good effect in waterproofing and heat insulation, easy construction, low cost, and good insulation performance.
Introduction of Insulation Pipe Quotation
The price of insulation pipe is mainly affected by its brand, manufacturer and specification size and other factors, in addition, the material of the pipe, the starting batch quantity, the seller, and the time of the day and so on, the amount of different factors also affect the price of the pipe to a certain extent. Below, is the latest offer of insulation steel pipe, as follows: (unit: yuan)
(1)Insulation glass fiber reinforced plastic pipe, Material: glass fiber reinforced plastic, Nominal outer diameter: 150 (mm), wall thickness 5 (mm), length: 6 (m), Zaoqiang County Runda Anti-corrosion and Environmental Protection Equipment Factory
30.00 (Starting batch of 1-9999? meters) 25.00 (Starting batch ≥10000?meters)(2)Thermal insulation steel pipe, Material: q235, Specification: 219-3620, Hebei Youfa Steel Pipe Manufacturing Co.

3600.00(Starting batch ≥1?t)Prefabricated Directly Buried Insulation Steel Pipe Performance Advantages
1, prefabricated directly buried insulation steel pipe does not need to masonry huge trench, only need to be buried in the insulated pipe underground, so greatly reducing the project occupies an area of land. Favorable to environmental protection, reduce the amount of earth excavation of about 50% above, reduce the amount of civil masonry and concrete 90%. At the same time, the insulation pipe construction and site trenching in parallel, only on-site joints, can shorten the construction period of about 50% or more.
2, good insulation performance, heat loss of only 25% of the traditional pipe, long-term operation can save a lot of energy, significantly reducing energy costs.
3, has a strong waterproof and corrosion resistance, without the need to attach the pipe trench, can be directly buried in the ground or water, construction is simple and rapid, low overall cost.
4, in the low temperature also has good corrosion resistance and impact resistance, can be buried directly into the frozen soil.
5, the service life of up to 30-50 years, the correct installation and use of the network maintenance costs are extremely low.
6, can be set up alarm system, automatic detection of pipe network leakage fault, accurate indication of fault location and automatic alarm.
Insulation steel pipe 5 big role
1, in the chemical plant production process, some chemical reactions are carried out in the pipeline or equipment, some requirements in the transport can not occur in the crystallization or solidification, which the temperature is a very important parameter, if the temperature is lowered, it will make the chemical reaction slows down, the occurrence of crystallization or solidification, causing Clogging. In order to prevent or reduce the temperature drop, it is necessary to carry out heat preservation
2, the pipeline and equipment outside the surface of condensation, because the surface temperature is lower than or equal to the dew point temperature of the surrounding air.
3, thermal piping and thermal equipment in the transportation and use of heat medium, because the piping and equipment within the temperature of the heat medium is higher than the surrounding air temperature, according to the second law of thermodynamics can be seen, the heat is always from the high-temperature objects to the low-temperature objects spontaneous transfer. This will have part of the heat from the pipe or equipment inside, through the metal wall to the surrounding air.
4, the vicinity of thermal pipelines and thermal equipment, there are combustible and flammable and explosive substances as well as wood-framed buildings, etc., when the pipeline or equipment inside the medium temperature is very high
5, some gases in the process of conveying due to the decrease in temperature.
The above is part of the insulation steel pipe offer summarized in this article, for reference only. For the insulation steel pipe, I recommend that you look at the size of its specifications when buying, but also pay attention to the consideration of transportation costs.
