Performance Characteristics
HDPE double-wall bellows have excellent chemical stability, aging resistance and environmental stress cracking resistance. The HDPE double-wall bellows produced as raw materials belong to flexible tubes. The main performance is as follows:
1. Strong resistance to external pressure
The outer wall is an annular corrugated structure, which considerably enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this aspect, HDPE double-wall corrugated pipe has obvious advantages compared with alternative pipes.
2. Low project cost
Under the condition of equal load, HDPE double-wall corrugated pipe only needs a thinner wall to meet the requirements. Therefore, compared with the solid wall tube of the same material specification, it can save about half of the raw materials, so the cost of HDPE double-wall corrugated pipe is also lower. This is another extremely prominent feature of the pipe.
3. Convenient construction
Due to the light weight of HDPE double-wall corrugated pipe, handling and connection are extremely convenient, so the construction is quick and maintenance is simple. Under the condition of tight construction period and poor construction conditions, its advantages are more obvious.
4, slight friction coefficient, large flow
HDPE double-wall corrugated pipe made of HDPE can pass through a greater flow rate than other pipes of the same caliber. In other words, the same flow requirements can use relatively tiny diameter HDPE double-wall corrugated pipe.
5, good low temperature resistance, impact resistance
The embrittlement temperature of HDPE double-wall bellows is -70℃. General low temperature conditions (above -30℃) do not need to take special protection measures when construction, winter construction is convenient, and HDPE double-wall corrugated pipe has excellent impact resistance.
6, excellent chemical stability
Since HDPE molecules are not polar, they are chemically stable. Except for a few strong oxidants, most chemical media have no destructive effect on it. Soil, electricity, acid and base factors in general use environment will not damage the pipeline, no bacteria breeding, no scaling, its circulation area will not decrease with the increase of operation time.
7, high service life
The service life of HDPE's double-wall bellows can reach more than 50 years under the condition of not being subjected to ultraviolet sunlight.
8, excellent wear resistance
Scope of application:
Germany has used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipe.
1. Drainage pipes and ventilation ducts of coal mines and buildings;
2. municipal road projects, underground drainage pipes and sewage pipes in residential areas;
3. irrigation water for farmland irrigation and waterlogging prevention; sewage treatment station, sewage treatment plant drainage pipeline transmission pipeline;
4. ventilation pipes for chemical plants and transportation pipes for fluid mechanics used in chemical plants and mining;
5. Overall production and processing of pipeline sewage inspection Wells; highway embedded pipeline;
6. high voltage cable, post and telecommunications cable protection sleeve, etc
Take you to the PE bellows
In the current urban and new rural construction process, because of the excellent performance of PE bellows, it is widely used in the construction of various pipelines.
So what exactly is PE below? What does it do? Below and China HDPE parts factory together to understand.
PE corrugated pipe, that is, polyethylene material extrusion molding plastic protective sleeve, because of its internal and external ring corrugated, also called corrugated pipe.
The pipe is a different type of pipe with an annular structure outer wall and a smooth inner wall. It was first developed in Germany in the early 1980s. Because of its excellent performance and relative economic cost, it has been considerably promoted and applied in Europe and America and other developed countries.
PE below features:
1. Annular wave structure, with both rigid and flexible high quality physical properties, ring stiffness, excellent flexibility, compressive strength, impact resistance, stable physical properties, corrosion resistance, no toxicity and zero pollution, belong to environmental protection pipe
2. Hollow rib bone structure, extremely light, transport, engineering construction is convenient and quick, reducing engineering construction costs.
3. Convenient connection, excellent sealing of connection head, reliable long-term operation quality, no leakage
4. The pipeline cavity is smooth, the fluid mechanics friction is tiny, the total flow is large, used for insulating sleeve engineering projects, the cable is extremely easy, the engineering construction efficiency
5. Good temperature resistance, wear resistance, buried service life can be almost 50 years or so, for cable sheath pipe, with excellent insulation characteristics and flame retardant grade, strong and durable, cable route operation can be trusted.
6. With appropriate tensile strain, the pipe fittings can be immediately installed in the slightly curved pipe trench without pipes, and the damage caused by the uneven foundation settlement of the road surface must be avoided.
