Detailed Product Description: | How to distinguish between good and bad to warm the pipe? Geothermal pipe on the market there are now two common warm polyethylene pipes and heat to warm the pipe cross-linked polyethylene, cross-linked polyethylene by cross-linking divided into: PE-Xa warm peroxide crosslinked polyethylene pipe; PE -Xb warm silane crosslinked polyethylene pipes and PE-Xc irradiation cross-linked polyethylene pipe to warm three kinds of heat-resistant polyethylene PE-RT has ordinary; transparent tube; color tube; EVOH oxygen barrier PE-RT pipes, etc. Also In some high-end home improvement and engineering fields, but also with ⑦PB polybutylene pipes to warm to warm to distinguish three kinds of cross-linked polyethylene tubing bad mainly to see the use of raw materials, production equipment usage, whether through 5000 8760 and other related tests; mainly to see Whether the use of pure raw materials, which manufacturers of pure raw materials, it also depends on 5000 8760 test and hot water; mainly depends on the strength of the production capacity of the raw material manufacturers and test cases. ppr tube top ten brands in the pipeline are welcome ppr pipe cleaning agents consulting agency, choose healthy pipeline of clean, clean pipes in building a better life with you. 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. Long-term hydrostatic strength curve look pert to warm the pipe from PE-RT predicts the existence of differences 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 curve for Approval of pert to warm the pipe, 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, then, in the current market environment, it is inevitable there will be a lot of PE-RT pipes production enterprises 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 pert to warm the pipe factory, with reference to foreign advanced standards and leading domestic enterprises Standard pert to warm after pipe manufacturer, and by five companies trials have demonstrated that, 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 _ the clean pipes (certified) _ Zhengzhou pert to warm the pipe supplied by Zhejiang Jie Pipeline Co. Zhengzhou office.
