High-density polyethylene (HDPE) has excellent chemical stability, aging resistance and environmental stress cracking resistance. The HDPE double-wall corrugated pipe produced from it is a flexible pipe. Its main performance is as follows: Strong resistance to external pressure The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil load. In this performance, the HDPE double-wall corrugated pipe has obvious advantages compared with other pipes. low engineering cost Under the same load condition, HDPE double-wall corrugated pipe only needs thinner pipe wall to meet the requirements. Therefore, compared with the solid-wall pipe of the same material and specification, it can save about half of the raw materials, so the cost of the HDPE double-wall corrugated pipe is also lower. This is another very prominent feature of the pipe. Easy to construct Due to the light weight of the HDPE double-wall corrugated pipe, the handling and connection are very convenient, so the construction is fast and the maintenance work is simple. Tight schedule and construction In the case of poor conditions, its advantages are even more obvious. Small friction coefficient, large flow The HDPE double-wall corrugated pipe made of HDPE can pass a larger flow than other pipes of the same diameter. In other words, under the same flow requirements, HDPE double-wall corrugated pipes with relatively small diameters can be used. Low temperature impact resistance The embrittlement temperature of HDPE double-wall corrugated pipe is -70℃. Generally, it is not necessary to take special protective measures during construction under low temperature conditions (above -30 ℃), and the construction in winter is convenient. Moreover, the HDPE double-wall corrugated pipe has good impact resistance. good 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. The soil, electricity, acid and alkali factors of the general use environment will not damage the pipeline, breed bacteria, and scale, and its flow area will not decrease with the increase of operating time. long lasting The service life of HDPE double-wall corrugated pipe can reach more than 50 years under the condition of not being exposed to sunlight and ultraviolet rays. Excellent wear resistance Germany has used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipes. proper deflection A certain length of HDPE double-wall corrugated pipe can be slightly deflected in the axial direction, not affected by a certain degree of uneven settlement of the ground, and can be directly laid in a slightly non-straight groove without pipe fittings. · Reasonable structure and beautiful appearance ·Temperature resistance -40℃-60℃ ·Small resistance, large flow ·Strong flame retardancy ·Long service life ·Reliable hygienic performance ·Low overall cost ·Acid and alkali resistance and corrosion resistance ·High strength, strong seismic performance ·Energy saving ·Easy to install and transport
There are many types of pipes, and the different types of materials have different applications. For example, double-wall corrugated pipes are used for drinking water transportation. What material is the double-wall corrugated pipe? What material is the double wall corrugated pipe It is a high-density polyethylene material, a new type of pipe with a ring-shaped outer wall and a very smooth inner wall. Because of its excellent performance and economic cost, it has been widely promoted and applied in many countries, especially in my country, the promotion and application of double-wall corrugated pipe is on the rise, and all technical indicators can reach the standard of use.
The most common problem with PPR water pipes is leaks. Be standardized when installing. 1. When using PPR fittings with metal threads, a foot seal must be used to avoid water leakage at the threads. 2. Do not overtighten the fittings to avoid cracks and leaks. 3. It is best to cut off 4-5cm at both ends of the pipe. 4. During construction in winter, the pipeline should avoid stepping on, knocking, colliding and throwing. 5. A boost test must be performed after installation. The pressure test time is 30 minutes, and the pressure is 8-10 kg, without leakage or leakage. 6. It is best to go to the top of the water pipe for easy maintenance. If it goes underground, it is difficult to find water leakage. 7. If it is found that the wall paint is moldy and blistered, the skirting or wooden floor is black and has fine bubbles, the ceiling and the wall tiles are damp and water seepage, etc., you should check the pipeline as soon as possible.
Matters needing attention in the installation of PVC drainage pipes in high-rise buildings (1) Sewage adopts PVC-U core foam drainage pipe, adhesive and flange interface. (2) According to the requirements of the drawings, combined with the actual situation, measure the size according to the position of the reserved opening, and draw the processing sketch (3) Measure the pipe size according to the sketch, and then break the pipe. The fracture should be flush, use a file or scraper to remove the flying spurs inside and outside the fracture, and file the outer edge at an angle of 15°C. (4) Before bonding, the socket and socket should be inserted into the test first, and not all of them should be inserted. Generally, it is 3/4 of the depth of the socket. After the test insertion is qualified, use a cotton cloth to wipe the moisture and dust of the socket to be bonded. If there is oil pollution, acetone is required to remove it. Apply the adhesive with a brush, apply the socket first and then the socket, and then insert it vertically with force. When inserting and bonding, turn the socket a little so that the adhesive is evenly distributed, and it can be firmly bonded in about 30-60 minutes. (5) When installing plastic drainage pipes, lead wires can be used to temporarily hang them for pre-installation. Adjust the coordinates, position, pipeline elevation and slope of the opening to meet the design requirements for bonding, and correct the coordinate position and elevation slope of the opening in time. After the bonding is cured, install the fixed support, but it should not be clamped too tightly. When a metal bracket is used, a rubber gasket must be placed in contact with the outer diameter of the pipe. (6) Inspection ports shall be provided at the lowest and highest floors of the drainage riser, and the center of the inspection port shall be 1.0 meters away from the ground. (7) After the pipeline is installed, the pipe hole should be blocked in time, and the mold should be blocked according to the requirements of the specification. It is strictly forbidden to climb or borrow the pipeline after installation. According to the above installation method, it can not only achieve the purpose of normal operation of the drainage pipe, but also ensure the normal service life of the PVC drainage pipe. However, we also need to remind that during the use of the pipeline, we must also do a good job of protection, and prohibit strong activities such as stepping on or smashing.
