Q61f plastic socket valve reinforced polypropylene (FRPP) is produced according to the standard hg20539-92 of the Ministry of chemical industry. It is extruded from high-quality glass fiber reinforced polypropylene. Our process technology overcomes the defects of low mechanical strength of polypropylene, maintains excellent corrosion resistance of polypropylene, improves the working temperature (-40 ℃ ~100 ℃), and forms the characteristics of high mechanical strength, good wear resistance, low cost, long service life, convenient installation and so on. It has become the best choice for anticorrosion in petrochemical, chlor alkali, chemical fiber, dye, light industry, sewage treatment and other industries.
