Zhengzhou, Henan Haotong Pipe Co., Ltd., is the Central Plains municipal drains relatively large double-wall corrugated HDPE pipe manufacturer HDPEX one place in the material properties of the crosslinked plastic manholes aftermarket fundamental change becomes not recycling, not plastic welding Manhole, so in addition to the environmental impact of increased costs also very large. PEX tube at room temperature greater rigidity, not easily bent or curved radius is large, corresponding in some small corner is difficult to bend and take up more space. Another impact performance is only half of PE-RT, while resistance to external pressure and the ability not to PP-R pipes. Zhengzhou, Henan Haotong Pipe Co., Ltd., is the Central Plains municipal drains relatively large composite layers of HDPE double wall corrugated pipe production enterprises is carried out under the plastic molten state; and Pipe (hollow wall pipe) secondary melt molding completely different plastic manholes price data, thus fully bonded between layers, very high fastness. Special pretreated plastic strip surface inspection wells performance to enhance corrosion resistance and adhesion to steel and plastic steel, improve the peel strength. Wrapped in plastic molding material fully molten state, the overall structure of the pipe solid and reliable. Due to the use of special materials and processes not only solve the steel corrosion problem solved adhesion steel and PE materials to make life and pure plastic pipe as the pipe to ensure that more than 50 years. Melt can be electrically connected to shrinking band connections, connect the inner and outer extrusion welding or a combination of multiple use, reliable connection. The pipe connections can be reliably achieve zero leakage. Plastic Manhole | Manhole performance plastics | ho-ho-management provided by the pipe industry.
