< . Double-wall corrugated pipe< . < . Double-wall corrugated pipe Double-wall corrugated pipe is professionally wholesaled by Hebei Likun Plastic Industry Manufacturer at a low price. Buy it later< . < . Double-wall corrugated pipe< . < . Double-wall corrugated pipe Double-wall corrugated pipe go to Hebei Likun Plastic Industry Manufacturer! .Hebei Likun Plastic Industry implements the national < B/< < < standards and establishes a complete quality assurance system with reference to the < < series of standards. It is equipped with a full set of advanced testing methods such as impact, ring stiffness, and flatness that match the advanced production line. The raw materials are made of high-quality resin and additives. The technology adopts international advanced technology, in accordance with the production process flow and process document requirements, and is controlled under the most ideal process conditions to produce high-quality << double-wall corrugated pipes. < < Double-wall corrugated pipe has beautiful appearance, strong pressure resistance, low water resistance, and resistance to acid and alkali corrosion. < < Double-wall corrugated pipes are easy to install and transport, and have significant advantages of energy saving, material saving and water saving.
.< Double-walled corrugated pipes are special pipes produced by using polyvinyl chloride as the main raw material and adding processing aids that are beneficial to the performance of the pipe. The inner wall is smooth, the outer wall is corrugated, and the inner and outer walls are hollow. < < Double-wall corrugated pipe has beautiful appearance, strong pressure resistance, low water resistance, and resistance to acid and alkali corrosion. < < Double-wall corrugated pipes are easy to install and transport, and have significant advantages of energy saving, material saving and water saving.
. Hebei Likun Plastic Industry< < Advantages of corrugated pipes:
.<, < < Corrugated pipes have excellent sanitary properties< < The molecular structure of the material is (< < ) One carbon and two hydrogen, even if it is decomposed, it is safe and non-toxic. < < The material is food hygiene grade and used in low-pressure water supply systems, without secondary pollution.
.< , < < The inner wall of the corrugated pipe is smooth, the water resistance is small, and there is no scaling< < The inner wall of the corrugated pipe is very smooth, and the absolute roughness of the inner wall < < does not exceed < <. < ,< and steel pipe ductile iron pipe< <. < ,< After < < years of operation, the < < value will increase to < -< times (caused by scaling). However, < < the molecular surface of the material does not have positive or negative charges, so the charged impurities in the water will not adhere to the pipe wall and will not scale. Therefore, the flow rate is also large. << The pipe diameter is the same as that of the metal pipe. Under the same pressure, the flow rate of the pipe is larger< /<.
.3< , < < The bellows has excellent low temperature resistance: < < The working temperature of the bellows is < -< ℃< < ℃. The working temperature range is very wide and can be within < < It can also be constructed in severe cold temperatures of ℃. < < Pipe is the only pipe material that does not crack when frozen.
.< , < < The excellent impact resistance of corrugated pipes is the best among all plastic pipes on the market today. < < , < < , < B< , < B< , < < have the best impact resistance. , through tests, the impact strength of < < is < < times that of < < and is < < times that of < <.
.< , < < The good dynamic fracture toughness of corrugated pipe< < is the resistance to rapid crack propagation. The value of < < for < < is < / and the value of < < for < is < <. < / The < < value for -< level is < <. < / -< level < < The value is < <. <
.< , < < Corrugated pipe has good electrical insulation properties< < The molecular chain is mostly composed of methylene (< -<) and does not contain polar genes, so it has very excellent dielectric properties. Within the range of current frequency < -<, the dielectric constant and dielectric loss tangent of < < are independent of the current frequency, so it is particularly suitable as an insulating material for high-frequency power supplies and electrical appliances. < < is a very good insulating material. The outer insulation layer of wires and cables is basically made of < <. < < Corrugated pipes can be used as direct buried sheathing pipes for cables or cast in concrete. The market for cable sheathing pipes is very popular. Various performance indicators are much stronger than < < cable sleeve.
.< , < < Bellows have good sealing performance and no leakage: < < There are two ways to connect corrugated pipes (< <) Socket connection (< <) Haruka crimping Both of these two connection methods can be basically leak-proof because they are both relatively traditional connection methods. It has been very successful and mature when used abroad. There are also many projects in China that have used it, and it will be better based on the results of use. The leakage rate can be controlled within < <, effectively controlling the pollution of groundwater resources. The benefit lies in the present time, and the merit lies in the future.
.< , < < Bellows have long service life< < The working environment of bellows is buried in the soil, free from ultraviolet radiation, and the working temperature is not high, generally < < ℃< < ℃, so the service life can be guaranteed to be < < years or more, which is basically synchronized with the life of the building.
