PE wrapped pipe

Hollow wall wrapped pipe is a structural wall pipe made of high-density polyethylene (HDPE) as raw material and produced by hot winding molding process. This pipe is suitable for transporting municipal drainage, outdoor drainage of buildings, buried farmland drainage, industrial sewage, road drainage, sewage treatment plants, sports field square engineering drainage, and electrical and telecommunications engineering with water temperature below 45 ℃. Due to the fact that hollow wall wrapped pipes are chemical building materials, they are of great significance in saving energy, reducing pollution, and protecting the environment.

Hollow wall winding pipe Hollow wall winding pipe HDPE winding pipe fully absorbs and digests technology from Germany, Finland, and Poland, with high technological content, reaching and exceeding PRENl 3476-1 standard. HDPE winding pipe is a new type of acid resistant, anti-corrosion, pressure resistant, and non-toxic green and environmentally friendly pipe, belonging to the high-tech product of environmental protection and energy saving. The product has a service life of more than 50 years, convenient transportation, easy construction, and low comprehensive engineering cost. It is an ideal replacement product for cement pipes, cast iron pipes, glass pipes, PVC-u corrugated pipes, and other products. HDPE winding pipes have fully absorbed and digested technologies from Germany, Finland, and Poland, with high technological content. They are now synchronized with world advanced technologies and meet or exceed the PRENl 3476-1 standard. Using imported high-quality high-density polyethylene as the main raw material, the product is extruded into a guide pipe through one extruder, and then wound with the extruded melt through a thermoforming machine through a second extruder.

With the promotion and application of HDPE hollow wall winding pipes in China, more designers and construction personnel will inevitably come into contact with this product. After a large amount of production and application accumulation, the performance characteristics of hollow wall winding pipes are as follows:

The special-shaped structural profiles extruded from the extruder die are evenly wound on the drum die at the predetermined position, and the PE melt material is synchronously extruded to fuse the special-shaped structural profiles into a whole, ensuring the quality of the structural wall pipe fusion joint. High quality welding seam

2. The pipeline adopts electric heating fusion tape or heat shrink tape connection technology, which is fast in construction, has high connection quality, and strong joint strength, ensuring the unity of interface material, structure and pipe body itself. Compared with rubber ring joints or other mechanical joints, there is no risk of leakage caused by joints. At the same time, due to its lighter weight compared to other pipes under the same application conditions, it is easy to transport and construct quickly, which can reduce construction costs. In application, the pipe can be directly laid without the need for a qualified concrete cushion layer and concrete pipe foundation trench. It can achieve simultaneous excavation, pipe laying, and backfilling, simplifying the construction process and shortening the construction period. Excellent installation performance, simple connection, reasonable joint sealing form, safe and reliable

HDPE is a high molecular weight polymer that provides excellent flexibility and overall resistance to external pressure for hollow wall wrapped pipes. When used on roads with heavy loads, it can ensure safe passage. Due to the flexibility of the pipes, when geological activities such as earthquakes and uneven ground settlement occur, the damage and loss of pipelines can be reduced to a very small extent, which improves the seismic and disaster reduction capabilities of public facilities. Has good flexibility and seismic performance

The 4 pipelines are formed using winding technology, which improves the ring stiffness of the pipes while saving materials. Has high ring stiffness

High density polyethylene has strong resistance to corrosion and chemical erosion, and does not require any anti-corrosion treatment when transporting corrosive fluids or laying in highly corrosive soil. Its performance is significantly better than other pipes. Due to its excellent aging resistance, it can ensure a service life of 50 years when used as a buried pipeline. Strong chemical and aging resistance

6. High density polyethylene wrapped structural wall pipes are processed without any additives, using 100% high-density polyethylene without any toxicity, scaling, or microbial growth. The cooling water of the product is recycled during the production process, producing no pollutants to the environment. Waste pipes of the same brand can be 100% recycled and reused. Good hygiene performance

The roughness N of the inner wall of the 7 hollow wall wrapped pipe is about 0.010, so the specific friction when transporting fluids is small, and the water delivery capacity can be significantly increased compared to cement pipes under the same usage conditions. Therefore, hollow wall wrapped pipes with smaller inner diameters can be used to replace cement pipes with larger inner diameters, reducing the project cost. The roughness of the inner wall of the pipe is low, and the water delivery capacity is large. In application, under the same conditions, the reliability of using hollow wall wrapped pipe engineering will be improved compared to traditional pipe materials, and the comprehensive benefits are obvious. Especially in narrow construction sites, dense buildings, complex underground pipelines, busy traffic sections, and when laying in acidic and alkaline soils, it is more advantageous.
