"Man Hua" brand of PE pipe performance advantages

With China PE pipe is not only has a good economy, but also has a series of advantages interface is stable and reliable, impact resistance, cracking resistance, aging resistance, corrosion resistance, compared with other enterprise pipe, pipe system over China in Tianjin Pipe limited production has a series of advantages:
1, the connection is reliable: between polyurethane insulating pipe pipeline system is connected with electric melting method, the joint strength is higher than the body strength pipeline.
2, polyurethane insulation low temperature embrittlement tube, can be used in the temperature range of -60-60 ℃. Winter construction, because the materials with good impact resistance, there will be no rattle tubes.
3, good stress cracking resistance: HDPE has low shear strength, high notch sensitivity and excellent ability of anti - scratch resistance, environmental stress cracking performance is also very prominent.
4, chemical corrosion resistance, good corrosion resistance: HDPE pipe of various chemical mediators, soil in the presence of chemical substances will not cause any degrading effect on pipeline. Polyethylene is an electrical insulator, it will not rot, rust or corrosion electrochemical; in addition it will not promote algae, bacteria or fungal growth.
5, aging resistance, long service life: polyethylene pipe containing 2-2.5% uniform distribution of carbon black can be stored or used for 50 years in the outside, not from ultraviolet radiation damage.
6, good wear resistance: show the contrast test of wear resistance of HDPE pipe and steel pipe, the wear resistance of HDPE pipeline steel is 4 times. Transmission in the field of mud, as compared with the steel pipe, HDPE pipe has better wear resistance, which means that the economy of HDPE pipe with a longer life and better.
7, flexible good: flexibility makes HDPE pipeline it is easy to bend, engineering by changing the direction of pipeline way around obstacles, on many occasions, to reduce the amount of pipe and reduces installation costs can be flexible pipeline.
8, small flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. Smooth performance and to ensure non adhesion properties of HDPE pipe has a higher than conventional transmission capacity pipe, but also reduces the pressure loss in piping and water consumption.
9, the transportation is convenient: the HDPE pipeline is lighter than concrete pipe, galvanized pipe and steel pipe, its easy handling and installation, lower the demand for manpower and equipment, means that greatly reduce the installation cost of the project.
10, a variety of new construction methods: HDPE pipe has a variety of construction technology, in addition to the traditional approach to construction of the excavation, still can use technologies such as trenchless pipe jacking, directional drilling, pipe, crack pipes, construction of various new, this is not allowed in some excavation sites, is the only choice, therefore, HDPE pipe broader applications.
