Detailed Product Description: | Structure: pipes and fittings will all into one industry standard pipe, pipe fittings, raw materials together as a whole standard "hot and cold water resistant polyethylene (PE-RT) piping system," Henan pert to warm the pipe wholesale, and GB for Approval is divided into three parts: the "hot and cold water resistant polyethylene (PE-RT) piping systems Part 1: General", "hot and cold water resistant polyethylene (PE RT) piping systems Part II: Pipe" "Hot and cold water resistant polyethylene (PE-RT) piping systems Part III: Fittings." The architecture reflects the status of the domestic PE-RT pipes domestic processing industry and largely maintained in line with relevant international standards. The concept: no emphasis on "ethylene-octene copolymer." The biggest difference between GB and industry standards for Approval is based on the prediction of the standard long-term static hydraulic PE-RT material intensity curve into PE-RTI-type material and PE-RTII type material. PE-RT predictions from long-term hydrostatic strength curve, the difference between the two inflection points for PE RTI curve-type material, and PE-RTII type material inflection curve does not exist. This suggests that the pipeline by PE RTII type material made of pipes from PE-RTI-type material made from long-term thermal performance is better than pressure. In the international standard ISO22391, PE-RTII type material curve is below the national standard for Approval of the curve, which is the result of international raw material manufacturers mutual compromise. Due to the current market PE-RTI-type materials can meet short-term hydrostatic strength of PE-RTII international standard-type material requirements, so inspection agency can not distinguish PE-RTI-type material and PE-RTII type material from the short-term performance . Thus, if in the evaluation of PE RTII type material performance, strictly in accordance with international standards in PE-RTII type material predict long-term hydrostatic strength curve pert to warm the pipe manufacturers, so pert to warm the pipe brand, in the current market environment, it is inevitable there will be a lot of PE-RT pipe manufacturer with PE-RTI-type material posing PE-RTII type material, so that consumers know what to do. In view of this, the standard drafting team in the development of PE-RTII type material standards process, is expected to involve PE-RTII type material of long-term hydrostatic strength curve and technical indicators, refer to the foreign advanced standards and leading enterprise standard pert warm tube, and after five trials have demonstrated that the enterprise, as long as the use of regular PE-RTII type PE-RT pipe material production, can achieve these standards. Ingredients: Do not add additives in the pipe processing. pert to warm the pipe manufacturer, Zhengzhou pert to warm the pipes, the pipes are provided by Zhejiang Jie Jie Pipeline Ltd., Zhengzhou office. Zhejiang Jie Pipeline Ltd., Zhengzhou Office (www.pprgc.com) strong, credible, Sheung Shui system in Zhengzhou industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead you hand in cleaning pipes and into the brilliant, for a better future! |
