What Should I Pay Attention To When Using HDPE Drainage Pipe?

HDPE Drainage Pipe is a new type of polymer material. It is the same as PPR, PVC and other materials. It is developed after the development of science and technology in the last century. The total polymer material is different from the other two materials. This material is put into production for a relatively short period of time. Due to the strong retractability of this new type of material, in the process of burying, if it is summer, the reserved length of the pipe body of HDPE Drainage Pipe is required to avoid the occurrence of pipe rupture at low temperature.

For the impurities passing through HDPE Drainage Pipe, it is necessary to carry out certain control. If the content of impurities is high, it will weaken the wall of HDPE drain pipe in the long-term. If it is serious, damage will occur. People need to pay attention to this point. There are many factors affecting the life of HDPE drainage pipes. People need to take precautionary measures to ensure their normal use.

The main material of HDPE Drainage Pipe is made of high-density polyethylene, so the properties of the material are also available. Although HDPE drainage pipes have good performance, they are not stable and will change due to temperature changes.

How Does The HDPE Siphon Pipe System Work?

The HDPE Siphon Pipe System is actually caused by the difference between the liquid-molecular attraction and the potential energy of the siphon phenomenon, that is, the water column pressure difference is used to make the water rise and then flow to a low position. Since the water surface of the HDPE Siphon Pipe is subjected to different atmospheric pressures, the water will flow from the pressure side to the pressure side until the atmospheric pressure on both sides is equal. The water level in the HDPE Siphon Pipe becomes the same height and the water stops flowing. At normal atmospheric pressure, the HDPE Siphon Pipe works better than in vacuum because the atmospheric pressure on the nozzles on both sides increases the pressure inside the entire siphon.

How To Choose HDPE Pipe Correctly?

With the increasing use of HDPE Pipe, there are more and more HDPE Drainage Pipe Factory products on the market, but there is a situation in which the products are mixed. So how to identify the quality of HDPE Pipe has become a topic of concern to buyers, so I will give some of my thoughts to everyone:

1. Observation method. It is through the eyes to observe and judge intuitively. Large Diameter HDPE Pipe is a polymer material with a relatively large molecular weight, so the surface is more round and shiny. This is a qualified product. Conversely, if the surface is dull or whitish, and even if there are bubbles on the surface, it means that the product quality is better. Second, it is possible to use refurbishment materials or additives.

2. Touch method. The real HDPE Pipe is smooth with a smooth surface and a layer of oil film, while the defective product is rough. This is a good judgment.

3. Experimental method. It can be squeezed or bent by force. The good HDPE Pipe is more tough and not easy to damage. The bad material is very brittle and the ductility is not good

Application Of HDPE Corrugated Pipe On Drainage Pipes

Nowadays, the real estate industry is developing rapidly. On the construction site, we can see a black plastic tube with a large diameter and a circle of corrugated plastic tubes on the pipe wall. What is this? In fact, this is a new type of plastic drain pipe, the industrial term is called HDPE Corrugated Pipe, its most important material is high-density polyethylene, but this pipe has pure German origin, which was first born in the 1980s, by Germany. After successful research and development, the production system and application technology have been perfected and advanced through decades. The main raw material of hdpe double-wall corrugated pipe is high-sensitivity polyethylene. The chemical equation of high-density polyethylene is nCH2=CH2→-[-CH2-CH2-]n-. It can be seen that it is mainly composed of carbon and hydrogen. Composition, and polyethylene is difficult to react with other chemical components due to inert data. For chemical reactions, it must be assisted by catalysts. Even if chemical reactions such as combustion occur, only water and carbon dioxide can be produced. Harmful ingredients, hdpe double-wall corrugated pipe also has anti-aging and anti-corrosion, equal pipe diameter and large flow, no siltation, no scaling, no bacteria, insulation and electricity, flexible, not easy to attack, rigid cracking, excellent adaptability to the construction site The ring has large rigidity and large bearing capacity, and the pipe material is easy to move and easy to construct. It can be used to accelerate the progress of the construction period. The applicable temperature is high and the embrittlement temperature is below 70 degrees Celsius. The long life of the pipe is used in the buried place without the ultraviolet rays. For more than 50 years.

How To Prevent HDPE Pipe From Bursting In Winter?

The appearance of HDPE pipes has brought a lot of convenience to people. For example, the water pipes and fire pipes are all HDPE pipes. Now the winter has arrived at the coldest time, the home should be warm, but many people I don’t know how to do this. Whenever there is some water pipe cracking in the home, how to prevent it? Let’s take a look at the High-temperature HDPE Pipe Supplier to learn about the winter water pipe burst.

First of all, it is necessary to plan the direction of the water pipe because of the direction of the water pipe laying, and sometimes it is also an important factor affecting safety. If the water in the water pipe is drained without using water for a long time, the water in the water pipe is prevented from freezing. If you find Long Life-span HDPE Water Supply Pipe icing, don’t rush to use thermal hydrolysis, so the water pipe is more likely to burst.

What Is The Difference Between HDPE Water Supply Pipe And HDPE Drainage Pipe?

Now HDPE pipes are also one of the HDPE pipes in agricultural water supply, fire hoses in cities, and so on. Due to its unique corrosion resistance, long use time and cold resistance, the HDPE tube is popular among many companies. There are many HDPE varieties on the market. Some people don’t know HDPE Water Supply Pipe and HDPE Drainage Pipe. Let’s talk about the difference between the two today.

HDPE Water Supply Pipe must withstand a certain pressure. Generally, PE resin with high molecular weight and good mechanical properties is selected. For example, HDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficult connection. Suitable as a material for the water supply pressure pipe. However, due to its high health index, HDPE resin has become a common material for the production of drinking water pipes. The HDPE resin has a small melt viscosity, good fluidity, and easy processing, and thus a wide selection range of its melt index, usually between 0.3 and 3 g/10 min.

HDPE Drainage Pipe is actually a high-density polyethylene double-wall corrugated pipe. Its main feature is that its external structure is especially a ring-shaped corrugated structure. In fact, this design is useful, which greatly increases the pipe. Ring stiffness to increase the resistance of the pipe to soil loading. This is an advantage that no pipe can replace, and HDPE pipe is cheaper. This is also a price advantage. The pvc drain pipe is mainly because it is not sensitive to the outside temperature, so there is little water pipe bursting phenomenon and its heat preservation is also good, so it is convenient to not generate condensed water. As for which one to choose, I feel that each has its own advantages depending on the situation.

HDPE Pipe Can Be Recycled And Fully Utilized

High Density Polyethylene HDPE Pipe is a suitable combination of four basic variables: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to customize the production of specific polymers. These variables are combined to produce HDPE grades for different purposes;

High Density HDPE Pipe is a non-toxic, odorless, odorless white granule with a melting point of about 130 ° C and a relative density of 0.941 to 0.960. It has excellent heat and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress cracking are also good.

HDPE Pipe Plastics recycles some of the fastest growing markets. Mainly because it is easy to process, has minimal degradation characteristics and applications in the filler. The main recovery is 25% recyclable materials, such as post-consumer recycling (PCR), which are treated and are not in contact with pure HDPE for the manufacture of food bottles.

Our HDPE pipe is widely used in many industries such as food, forestry, pharmacy, and papermaking.

What Is The Application Of Hdpe Pipe In Gas?

HDPE Pipe has medium density polyethylene pipe and High Density Polyethylene Pipe. According to the wall thickness, it is divided into SDR11 and SDR17.6 series. The former is suitable for conveying gaseous artificial gas, natural gas, and liquefied petroleum gas. The high density polyethylene pipe is mainly used to transport natural gas. Compared with steel pipes, the construction process is simple, has certain flexibility, and more importantly, it is not used for anti-corrosion treatment, which will save a lot of processes. Disadvantages are not as good as steel pipes. Special attention is paid to the safe spacing of thermal heating during construction, and it should not be exposed to the sunlight in the air, and it is sensitive to chemicals and prevents leakage of sewage pipes.

China’s municipal pipe market, where sewage pipes and HDPE Gas Pipe are the two largest application markets. HDPE Chemical Chinese name, polyethylene, HDPE material is widely used in the field of water supply and drainage manufacturing due to its high strength, high temperature resistance, corrosion resistance, non-toxicity and wear resistance. Because it does not rust, it is an ideal pipe to replace the ordinary iron water supply pipe.

HDPE Corrugated Pipe Construction Technology In Municipal Engineering

HDPE Corrugated Pipe construction technology in municipal rainwater pipes:

(1) Trench excavation. Before excavating the trenches of the pipeline, comprehensively understand the geological conditions of the construction site, the groundwater conditions, and the design requirements of the rainwater system, and reasonably determine the buried depth and basic treatment methods of the pipeline. Among them, the most important task is to verify the bearing capacity of the foundation foundation. If it does not meet the construction requirements, it should be treated by means of replacement and riprap to improve the bearing capacity of the foundation. After preparing for the construction, the trenches are mined according to the pipeline construction plan, and the geometrical dimensions of the grooves must conform to the design scheme. If there are loose stones and clods at the bottom of the groove, remove it and lay a sand layer on it, tamping and leveling to prevent the hard object from damaging the HDPE Corrugated Pipe.

(2) Installation. Install the HDPE double-wall corrugated pipe and review the parameters such as the depth, width and bottom hole elevation of the groove. After confirming that there are no gravel or broken soil in the groove, the installation work is officially started. The HDPE double-wall corrugated pipe itself is of low quality and generally does not require a large hoisting device. If the pipeline is buried below 3.0m and the diameter is lower than DN500, the lower tube can be manually used. If the pipeline is buried deeper than 3.0m and the diameter is higher than DN500, it needs to be installed by hoisting. When hoisting and installing, the pipe should be laid down to the bottom of the groove to be stable, and the foundation cannot be disturbed. When it is necessary to cut the pipe, the pipe cut surface should be vertical and flat, and the pipe itself cannot be damaged. When installing, pay attention to the following points: First, the pipeline should be laid straight, if the line is to be laid, the relative rotation angle should not be greater than 2. Secondly, after the pipeline is lowered, the drainage in the trench should be good, there should be no water accumulation to prevent electric shock accidents; third, the interface between the pipe and the pipe should have a certain vacancy to facilitate subsequent connection.

(3) Connection. HDPE Corrugated Pipe connection methods mainly include heat shrink sleeve connection, electric hot melt ribbon connection, etc., and the operation points are different. In the heat shrinkable sleeve connection mode, first clean the surface moisture and debris of the pipe, and tightly entangle the pipe joint with the heat shrink tape, and slightly heat the contact zone between the heat shrink tape and the pipe with a flame gun. After that, the other heat shrinkable tape is used to wrap the baked heat shrinkable tape, and the clip is clamped, and then baked with a flame gun in the heat shrinkable tape wrapping portion, first up and down, left and right, so that the heat shrinkable tape and the pipe are completely tight. paste. In the electric hot melt belt connection mode, the surface of the pipe should also be cleaned first, and the joint part should be wrapped with electric heating tape, and fastened with a buckle. Connect the electric hot melt belt to the electric hot melt machine to set the current intensity and heating time. After the electric fuse is completed, fasten the buckle and cool it for a while. After checking that the connection quality meets the standard requirements, loosen the buckle. In addition to the connection between the pipe and the pipe, the connection of the HDPE Corrugated Pipe to the well should also be emphasized. The H DPE double-wall corrugated pipe first penetrates into the well from the pipe trench and supports the pipe with support to prevent concentrated load or shear. Commonly used method for connecting H DPE double-wall corrugated pipe and well wall: Apply PVC adhesive on the joint of HDPE double-wall corrugated pipe and well wall, lay a layer of fine sand on it, and deep the pipe wall In the middle, the cement mortar is used to build the blockage.

(4) Closed water test. After the pipeline is connected, conduct a water shut-off test to confirm whether the tightness of the pipeline in the water injection condition meets the requirements. First, check the inside of the pipe for blockages, water accumulation, etc. After confirming that there is no such situation, inject water into the pipe. After the water is injected, keep it for a while. If the pipeline project is large in scale and it is impossible to implement the closed water experiment one by one, the closed water test pipeline can be determined by sampling. If water seepage or water leakage is found, stop the test immediately, re-connect the pipe, and conduct the closed water test again.

(5) Backfilling. After completing the above work, proceed to backfill the work. First backfill from the joint between the pipeline and the foundation. The method is symmetrical. It is forbidden to backfill the other side after backfilling. The tamping also uses a symmetrical approach to reduce the impact on the pipeline and avoid deformation of the pipeline. When backfilling, the layered filling method is adopted, and the thickness of each backfill is controlled between 0.15m and 0.20m. The thickness of the backfill layer at the top of the pipe is about 0.70m. If conditions permit, mechanical rolling can be used to ensure that the backfill compaction meets the design requirements.
