Glass fiber reinforced polypropylene (PP) and polyethylene (PE) pipes are produced according to the HG20539-92 standard, with specifications De20-De800mm and nominal pressure 0.4-1.0MPa, using glass fiber modified polypropylene raw materials treated with coupling agents. The products feature corrosion resistance, high strength, leakage resistance, low internal resistance, tensile strength, bending resistance, low cost, long service life, and convenient installation and maintenance. They are widely used in petroleum, chemical, electric power, textile, metallurgy, pharmaceutical, papermaking, food, mining, waste treatment, construction, and other industries for conveying corrosive liquids and as process pipes, and are deeply trusted by users. (PP) Engineering grade polypropylene pipes are extruded from engineering grade polypropylene granules. The pipes are non-toxic, odorless, and widely used in chemical, environmental protection, food hygiene, building water supply and drainage, and other fields (executing QB1929-93 standard). The specifications and performance of glass fiber reinforced polypropylene FRPP pipes are introduced as follows: 
pp pipe excellent quality 
◇ Long service life-----Under rated temperature and pressure conditions, FRPP pipes can be safely used for more than 50 years. 
◇ Excellent corrosion resistance-----FRPP pipes can withstand the corrosion of most chemicals and can withstand high concentrations of acids and alkalis with a pH value range of 1-14 within a large range. 
◇ Excellent wear resistance-----When conveying ore sand and mud, the wear resistance of FRPP pipes is more than 4 times that of steel pipes. 
◇ High stiffness-----Due to the addition of glass fiber reinforced materials, FRPP pipes are not easy to deform. 
◇ Heat resistance, thermal insulation, and energy saving-----The maximum use temperature of FRPP pipes is about 95 degrees. The thermal conductivity of this product is only 1/200 of that of steel pipes, so it has good thermal insulation performance. 
◇ Reliable connection performance-----The strength of the FRPP pipe hot melt interface is higher than that of the pipe body, and the joints will not break due to soil movement or load action. 
◇ Good construction performance-----FRPP pipes are lightweight, the welding process is simple, construction is convenient, and the comprehensive project cost
