※ Product Introduction
Guizhou Guosu adopts advanced production equipment, imports high-quality pipeline materials, and carefully creates PE-RT series pipes, which are widely used in various underfloor heating projects and drinking water pipeline projects. PE-RT pipes have been rated as a famous brand product in China's floor heating industry, a recommended product in China's floor heating industry, and highly recognized by users. At the same time, the company has a complete range of PE-RT pipes and fittings, with good hot melt connection performance, making it easy to choose and use.
The prefabricated insulation plastic pipe with heat-resistant polyethylene PE-RT Nie type pipe as the working pipe can effectively solve the problems of corrosion, short service life, serious "leakage", large heat loss, and poor water quality in the current centralized heating network, while also reducing! Construction cost, shortened construction period, convenient construction, and good economic, social, and environmental benefits. This product is suitable for centralized heating pipeline systems with a design temperature not exceeding 85 ℃ and a working pressure not exceeding 1.0 MPa. It has been recommended by the Ministry of Housing and Urban Rural Development and has broad market application prospects.
※ P P - R T I I Product Features
1Large diameter plastic pipes suitable for hot water transportationPE-RT II type pipes can be used for large-diameter plastic pipes for hot water transportation. The PE-RT II type pipeline raw material has excellent processing performance, adopts a bimodal distribution structure, and the resin has low melting point processing characteristics, which can produce large-diameter cold and hot water transportation pipelines.
2Excellent pressure resistance under high temperature conditions： 1Extrapolating long-term（20℃ , 50The minimum static hydraulic strength exceeds10MPa， Reaching PE100Level pipeline requirements.2Can be applied for a long time80Hot water delivery at ℃.3 .110At ℃, the static hydraulic test has exceeded10000h， Has outstanding thermal stability performance.4Under any temperature conditions,876 0Before h, the predicted strength curve of the hydrostatic pressure had no inflection point and no brittle failure.5Oxidation induction time is greater than20min， It has outstanding anti-aging performance.
3Has extremely high resistance to stress cracking The resistance of the pipe to slow crack growth in the cut test exceeds 2000 h, and the full cut creep test passes 10000 h. The pipeline has excellent scratch resistance and the ability to resist external environmental damage, ensuring the safe use of the pipeline throughout its entire life cycle.
3Compared to other hot water pipelines, it has better resistance to low temperature impactIt has excellent low-temperature resistance and can maintain excellent impact resistance even at - 40 ℃, completely solving the problem of low-temperature brittleness in other cold and hot water transportation pipelines in winter.
4Equipped with fast plastic pipe connection methodsHot melt docking, electric fusion connection and other connection methods can be used for convenient and reliable connection. Flanges and other mechanical connections can be made with other materials of pipelines to achieve interconnectivity of the entire pipeline system.
5High mechanical strength and toughnessHas good impact resistance, compression resistance, and wear resistance, can withstand certain formation pressure and external impact, and is not easily deformed or broken. Sanitary and environmentally friendly materials are non-toxic and odorless, and will not cause secondary pollution to the water supply and quality in mines.
