FRPP pipe has the characteristics of corrosion resistance, high strength, anti-leakage, small internal resistance, tensile strength, bending resistance, low cost, long service life and convenient installation and maintenance. The tube can transport various corrosive media below 120 ° C and is a substitute material for stainless steel pipes. Engineering grade polypropylene tubing is extruded from engineered grade polypropylene pellets. The pipe is non-toxic, tasteless and widely used in chemical, environmental protection, food hygiene, building water supply and drainage and other fields.

First, FRPP pipe standard

1. Execute HG 20539-92.

2. It is produced by processing glass fiber modified polypropylene material, which can transport water for general use or corrosive liquid.

3. The sanitary performance of drinking water pipes complies with the provisions of GB/T17219.

Second, the advantages of FRPP tube

1. Service life: FRPP pipeline can be safely used for more than 50 years under rated temperature and pressure conditions.

2, corrosion resistance: FRPP pipe can withstand the corrosion of most chemicals, can withstand a high range of acid and alkali corrosion with a pH range of 1-14. It has good corrosion resistance to non-oxidizing acids (hydrochloric acid, ene sulfuric acid, hydrofluoric acid, dilute nitric acid, alkali and salt solution).

3, anti-wear performance: When transporting ore mud, the wear resistance of FRPP pipe is more than 4 times that of steel pipe.

4, stiffness performance: FRPP pipe due to the addition of glass fiber reinforced materials to make FRPP pipe is not easy to deform heat-resistant insulation energy-saving performance: FRPP pipe maximum use temperature of about 95 degrees, the thermal conductivity of the product is only 1 / 200 of the steel pipe, so there are Good insulation performance.

5. Connection performance: The strength of the FRPP pipe hot melt interface is higher than that of the pipe body, and the joint will not be broken due to soil movement or load. Good construction performance: FRPP pipe material is light, the welding process is simple, the construction is convenient, and the comprehensive construction cost is low.

Third, the characteristics of FRPP tube

1. Long service life; FRPP pipe can be safely used for more than 50 years under rated temperature and pressure conditions.

2, excellent corrosion resistance; can withstand the corrosion of most chemicals, can withstand a high range of acid and alkali corrosion with a pH range of 1-14.

3, excellent anti-wear performance; when transporting ore mud, the wear resistance of the pipe is more than 4 times that of steel pipe.

4, higher steel; FRPP pipe is not easily deformed due to the addition of glass fiber reinforced materials

5. Reliable connection performance; the strength of the FRPP tube hot melt interface is higher than that of the pipe body, and the joint will not be broken due to soil movement or load.

6, good construction performance; light pipeline, simple welding process, convenient construction, low comprehensive engineering cost.

Fourth, FRPP pipe main connection size
