Hebei PP Pipe Manufacturer - Best Selling - Manufacturer - Price - Factory Phone Number [Zhenjiang Chenghua Pipe Industry Co., Ltd.] PP pipes are a non-toxic, hygienic, high-temperature resistant, and recyclable pipe type, mainly used in building indoor cold and hot water supply systems and also widely applicable in heating systems. The features of PP pipes include anti-corrosion, wear resistance, no scaling, vibration and noise reduction, frost-proof (PP pipes can crack at temperatures below -20℃, decomposition occurs at temperatures above 70℃ in high-temperature environments), frost prevention, low heat loss, easy installation, and long service life. Connection methods include welding, end welding, and different material joints. FRPP pipes (fiberglass reinforced polypropylene pipes) are produced from modified polypropylene materials with glass fibers treated with coupling agents, in accordance with HG20539-92 standards, with specifications ranging from De15 to De1500mm, nominal pressure of 0.4-1.0MPa, corrosion resistance, high-temperature resistance, high-pressure resistance, hygiene and non-toxicity, recyclable, suitable for transporting corrosive liquids (such as acid and alkali solutions) and municipal water supply and drainage systems. They have good impact resistance and tensile strength, are lightweight, and easy to install and maintain. Applications are widespread in the chemical, chemical fiber, chlorine alkali, dye, water supply and drainage, food, medicine, and wastewater treatment industries.
