High-density polyethylene winding structure wall B type pipe, also known as: carat pipe. It is a kind of special-shaped wall pipe with smooth inner wall and screw tube reinforced ribs on the outer wall. It is made by a spiral winding process and belongs to a flexible pipe. Polyethylene winding structure wall B tube is made of high-density polyethylene as raw material. It is made by winding forming process in a hot melt state. Before being demoulded in a hot state, it is cooled by rolling air cooling, and the pipe gradually dissipates heat and the wall is thick. The two ends of the pipe are processed into socket and socket during production, and the electric fuse is embedded in the socket end. When the pipe is connected, the welding can be completed only by connecting the power supply, and the polyethylene winding structure wall B-type pipe system can realize zero leakage.
Below, HDPE pipe fitting suppliers give a systematic look at the fitting pipes by including their connection mode, transportation, storage and production process.
1. Elevated-density polyethylene winding structure wall type B tube connection modes: plug and socket electric fusion connection, plug and socket rubber ring connection, throttle rubber ring connection.
Two, polyethylene winding structure wall B-type pipe transportation and storage:
1, short distance handling, should not be in the rough uneven ground or stone ground rolling, to prevent damage to the pipeline.
2. When the inner diameter is greater than 1000mm, it is not suitable for stacking transportation. If the light-caliber polyethylene winding structure wall B-type pipe is used for stacking transportation, the pipe should be kept stable and gaps should be left between the pipes to prevent the pipeline from sliding.
3, stacked transport, its height should not exceed 2 meters. The contact place between the vehicle and the ship and the pipeline shall be flat, and it shall be fixed on the transport vehicle with a flexible belt or rope to prevent rolling and collision.
4. If the inner diameter is greater than or equal to 1000mm, a support ring should be added for transportation. If the inner diameter is greater than 2000mm, a support ring must be added.
5, when the polyethylene winding structure wall B tube is directly placed on the ground, the ground is required to be flat, there should be no stones and sharp objects easy to cause pipeline damage, and there should be measures to prevent pipeline rolling.
6. When stacking polyethylene winding structure wall B-type pipes of different pipe diameters, the large and heavy side should be put down and gently placed on the top. Both sides of the pipe should be blocked by wooden wedges or boards.
7. The maximum operating temperature of polyethylene winding structure wall B-type tube is 45 degrees Celsius. In summer, it should avoid sunlight exposure and keep the air circulation between tubes to prevent the temperature from rising.
8. During storage of B-type pipe with polyethylene winding structure, waterproof measures should be strictly taken and the socket should be kept clean. 9. It is strictly prohibited to have long-term open flame near B-type pipe of polyethylene winding structure wall.
Three, polyethylene winding structure wall B-type tube production process:
1. The excellent installation performance of polyethylene winding structure wall B-type pipe connection adopts the technology of embedded electric fuse in the socket with the same material, and the connection quality is elevated. No leakage can be achieved to ensure the life of the pipeline system and the safety of operation. At the same time, because the product under the same application conditions as other pipe weight, convenient transportation, convenient construction, can reduce the construction cost, in the application range, do not need the concrete mat and concrete pipe base trench qualified can be directly applied pipe, essentially do excavation, pipe down, side backfill, simplify the construction procedure, shorten the construction period. In the project acceptance, closed air inspection is used instead of closed water test, which not only speeds up the acceptance speed, but also saves the complicated work and a lot of test costs in closed water tests.
2, excellent flexibility High density polyethylene winding structure wall B-type pipe has excellent flexibility on the macro level, but the local pipe section has strong rigidity and the overall resistance to external pressure, when used under the road surface with overweight load, it can ensure the safety of traffic. Due to the flexibility of the pipe, the damage loss of the pipe can be minimized in the event of earthquake, uneven settlement of the surface and other geological activities, so as to improve the seismic disaster reduction ability of public facilities.
3. HDPE can be recycled and used. It is elevated density polypropylene, the main raw material of winding structure wall tube of green environmental protection products, without any toxicity and without any dye produced in the production process. It is an environmentally friendly and safe green product.
4, corrosion resistance, aging resistance, service life to ensure 50 years elevated density polyethylene has a strong resistance to chemical corrosion and erosion. Therefore, polyethylene winding structure wall type B pipe does not need anti-corrosion treatment when conveying corrosive fluid or laying in corrosive soil, and its performance is considerably better than other pipes. The product in the design process, chooses a reasonable product structure form, to ensure that the service life of the plastic tube is more than 50 years, and in the life span of maintenance free.
5, tube inner wall roughness is low, large water transfer around the structure of the wall pipe product inner wall roughness N is about 0.010, so the fluid transport than friction resistance is tiny, relative to the inner diameter of other passenger tickets and, under the same conditions of use water transfer than cement pipe can be considerably improved. Therefore, polyethylene winding structure wall type B pipe with smaller inner diameter can be used to replace the cement pipe with larger inner diameter. In the application, the engineering and reliability of winding structure wall pipe will be improved compared with the traditional pipe under the same conditions, and the comprehensive benefit is obvious, especially when the construction site is narrow, the construction is dense, the underground pipeline is complex and the traffic section is busy, and the laying in acid and alkaline soil is superior.
