Steel Reinforced Spirally Wound PE Drainage Pipe Machine
Steel Reinforced Spirally Wound PE Drainage Pipe Machine
The pipe is made from steel reinforced polyethylene profile that is formed by integrating HDPE with steel strips by means of an integration machine. The profiles are welded by HDPE extrudant at the profile edges which is overlapped by a winding and welding machine to form the pipe. The pipe is of spiral structure with concentric steel reinforced HDPE ribs, which are equidistantly distributed round the circumference of the pipe, extending vertically upward from the basic pipe body. In the pipe HDPE forms pipe bore and steel offers ring stiffness. The thickness and breadth for the steel strip is determined according to different pipe diameter and ring stiffness class requirements.
Pipe characteristics and benefits:
1,Unique structure resulting in excellent comprehensive properties
The steel strip encased in polyethylene provides sufficient strength for the pipe to withstand soil and traffic load.
The basic material of the pipe body is polyethylene, which had been proved to have excellent anticorrosion resistance, hydraulic characteristics and proper flexibility. Pipe represents the most reliable, sate and sound integration of the desirable properties of steel and polyethylene.
2, High ring stiffness easily achieved at low pipe weight, which can be maintained over pipe life
The elastic modulus of steel is more than 200 times that of polyethylene, and the density of the two materials differs 7.85 times, so high ring stiff value and higher ring stiffness to weight ratio can be easily achieved in this pipe, especially for larger sizes. HDPE is prone to creeping but steel does creep at application temperatures of the pipe, so that this pipe, wherein ht strength is provided by steel, has more stable long-term strength than other pipe materials.
3, Light in weight
Duo to its high ring stiffness to weight ratio, this pipe is lighter than any other pure plastic pipe of equal ring stiffness.
4, Excellent corrosion resistance and thus durable.
PE is inert to almost all chemical materials. In this pipe the steel strip is completely enwrapped in polyethylene, and as a result the pipe has same anticorrosion performance as pure PE pipes do.
5, Great resistance to abnormal stress
Due to its high ring stiffness and proper axial flexibility, in case that soil sinking, groundwater floating, earthquake or excessive local load occurs, the pipe is able to relieve the excessive stress caused thereby through elastic deformation and consequently avoid leakage or damage at the joint or failure of the pipe.
6, Pipe production nearby installation site easily achievable.
For pipes of Dn200~1200mm, pipe production nearby construction site is easily achievable thanks to noncomplexity in production process and easiness in reinstallation and transportation of production facilities.
7, Simple installation saving much cost & labor.
The pipe is lightweight and does not need heavy lifting equipment at installation site; the pipe can be as long as up to 6-12 meters and use less joint; both jointing methods are easy and convenient requiring simple tools and less labor efforts.
8, Excellent abrasion resistance.
Abrasion resistance of PE is 3 to 5 times better than that of metal and cement.
9, Long life expectancy.
The life expectancy of the pipe is expected to be 50 to 100 years, much longer than that of traditional metal and cement pipes.
10, Zero pollution to the environment achieved by leakfree joint.
Pipe jointing by either of the two methods is leakfree, and does not pose threat to the surrounding environment when used for sewers.
11, Does not cause secondary pollution.
When used for gravity transportation of drinking water, this pipe does not cause secondary pollution as concrete or cast iron pipe does.
