Compared with other pipes
1. Flow Comparison
HDPE high density PE double-wall corrugated pipe: The absolute roughness of inner wall is only 0.009mm,minimum friction resistance coefficients, and it won’t be changed with time during the term of use. In graveity flow systerm, equal flow required, so the required inner dinemeter of PE double-wall corrugated pipe should be smaller than pipes in other materials. After caculation, it shows that if we want equal flow, the inner diameter of PE double-wall corrugated pipe is only 96% of stainless steel pipe, 87.7% of nodular cast iron pipe and 90.6% of cement pipe, which means we could save large amount of engineering material when use PE double-wall corrugated pipe.

Corrosion resistance |
It has strong acid and alkali corrosion resistance, it won’t be corroded in sea water, acid and alkali soil. |
Better |
No acide and alkali Corrosion resistance, the serious will occur leakage and underground pollution |
Impact Resistance |
Good impact resistance |
It will have crack and risk of break under impact of hard things. Bad impact resistance. |

Application property |
Save mechanical expenses,easy connection, it has gurantee for construction quality in water(The minumum work temperature is -30），good application property, especially suitable for northern area
|
Connect by rubber plastic ring of bonding easier construction, but no guarantee for construction quality in winter(The minmum work temperature is 5 度 |
Heavu material, transportation and construction are not easy. Bad operating in manual connection |

Tianjin Baoli Shengni Plastic Pipe Manufacturing Co., Ltd. was established in 2003 with a registered capital of 61.88 million. The company is located in Tianjin Jinghai Economic Development Zone, covering an area of 50,000 square meters, close to Beijing-Shanghai, Beijing-Guangzhou Expressway and Tianjin. Hong Kong, Huanghua Port, Binhai New Area, and the national market. In the second half of 2008, Tianjin Jinhe Bimetal Wire Co., Ltd. completely acquired the company, which not only injected a lot of money into the company, but also made the company's business philosophy and quality consciousness completely new. In a short period of time, the company has developed into a high-tech enterprise integrating scientific research, development, production and sales. It specializes in producing HDPE high-density polyethylene double-wall corrugated pipe and large-diameter steel belt reinforced polyethylene spiral corrugated pipe. The company has passed ISO9001 system certification, has more than 200 employees, 13 and two large-scale workshops, with an annual output of 30,000 tons. The excellent products and perfect services have been recognized by local merchants.
The company adopts internationally advanced technology and equipment to produce new green environmental protection pipe. This product is a national-level torch promotion project and is a new type of pipe that the country vigorously promotes.
Our company pays attention to quality, focus on management, guarantees with strong technical force, adopts strict quality management system, and provides users with all-round technical support according to the standards of “new technology, high quality” and our sincerity and confidence. service.
