Product Introduction
"ERA Brand" steel tape reinforced polyethylene spiral corrugated pipe (referred to as steel tape pipe) is a wound structural wall pipe that is composed of high-density polyethylene (PE) as the substrate (inner and outer layers) and surface coated with adhesive resin steel tape. The inner layer of the structure is formed by continuous spiral winding of a layer of HDPE, the intermediate layer is formed by circular winding of a coated steel strip (Ω type), and the outermost layer is composed of three aspects: a continuous spiral winding of a layer of HDPE. Steel strip pipe has a series of advantages such as high corrosion resistance, low friction resistance, high ring stiffness, and high cost performance, making it a "strong player" in the pipeline market of Anhui Province.
Technological innovation
01 Product Features
1. Corrosion resistance: The pipe material is corrosion resistant PE material, which will not be corroded by chemicals in sewage and wastewater.
Flexible pipe: When subjected to external impact forces, it has excellent performance in restoring its original shape, and is not easy to crack in case of foundation settlement.
3. Anti aging: the base material of the pipeline can be effectively used for more than 50 years at 20 ℃.
4. Cold resistance: In an environment of minus 60 ℃, the pipes will not freeze or leak.
5. Portable type: The weight of the pipe is only 1/8 of that of the same specification concrete pipe, which is convenient for transportation and construction, and does not require the use of large construction equipment.
6. Time saving: Convenient connection and low requirements for excavation works. During the construction of urban drainage works, simple and rapid construction can be carried out on site, which can greatly save project time and cost.
Low friction coefficient: strong medium conveying capacity. Smooth interior, low frictional resistance, and fast drainage.
8. Non toxic: Polyethylene itself is a non-toxic renewable material that will not cause pollution to the environment.

03Advantages of connection method
Currently, in the steel strip pipe industry, the main methods of pipe jointing are heat shrinkable sleeves, electrofusion tapes, flange locks, and rotational plastic sockets. The advantages and disadvantages of the above methods are obvious, for example, the installation process of heat shrinkable sleeves and electric fusion tapes is greatly affected by the environment; The installation of flange lock catch is cumbersome and not convenient enough; The probability of faulty welding of steel strip pipe made of rotational plastic socket is relatively high. Based on the advantages and disadvantages of the above connection methods, Anhui ERA., through discussion at the meeting, drew on the successful experience of polyethylene A-type winding structure pipe joints to develop online extrusion type joints for steel strip pipes.
The integrated extrusion molded steel strip pipe socket joint has excellent water tightness, and the pipe itself is firmly bonded to the joint without faulty welding. At the same time, the appearance of the joint is high-end, atmospheric, and high-grade, meeting the aesthetic needs of the market.
Socket type connection VS electric fusion belt welding: it does not require power supply for heating and melting, nor does it need to consider factors such as weather and construction environment, which can save a lot of manpower and material resources.
