Liande Pipe Co., Ltd., Zhengzhou is located in Zhengzhou City, the new secret industry gathering area, and adjacent to Xinzheng, 20 kilometers away from Zhengzhou city, only 30 km away from Xinzheng International Airport, the transportation is very convenient, the company covers an area of ??30,000 square meters. The company is set research and development, production and sales of hard work-oriented enterprises. Our main products are: high density polyethylene (HDPE) double-wall corrugated pipe, PE pipe, HDPE reinforced spiral corrugated steel pipe, rigid polyvinyl chloride (UPVC) double-wall corrugated pipe, CPVC, MPP power tube, communication with perforated pipe, the annual production capacity of 1 million tons. Companies adhere to the fundamental quality, service to win market integrity and philosophy of development, innovation, become the industry pioneer. Quality: Quality is the basis of raw materials, the company set up a special laboratory of raw materials and finished goods, raw materials for all Cengcengbaguan detected before the indicators finished product storage, followed by strong technical force, scientific formula for the product of the foundation. Service to win the market, the company established a complete sales and after-sale technical guidance to the professional ranks, allowing users to not only get high quality products, but also enjoy a high standard of service. Integrity and development: the company has always been convinced victory by wisdom, victory by Germany, Germany and the integrity of the development of the road, let us join hands in hand, to Germany for a better future. HDPE gas pipe materials used in almost all using imported raw materials, the main level is PE100 and PE80. China has not mass-produced PE gas pipe HDPE gas pipe Compound, high-density polyethylene general strength and hardness are better than gas pipe Compound higher. But for the pipe, it will generate over time of aging, mechanical properties and physical properties are attenuated, the initial pipe ductile failure by brittle fracture transition attenuation after aging. For the decay of the aging process, the gas pipe than the average HDPE Compound much slower. Therefore, it is used primarily use MDPE gas pipe Compound. MDPE Gas Pipe material below has strict performance requirements of relevant international standards ISO04437-1997 and GB15558.1 standards to ensure that under normal circumstances the service life of 50 years.
