Specifications of PPR Pipes
2021-07-23
PPR Pipes is divided into cold and hot water pipes:
The pipe diameter is the outer circle. Size: 20 /25 /32 / 40 /50 /63/75 /90 /110 mm;
Wall thickness of cold water 1.25Mpa: 2.0/2.3/2.9/3.7/4.6/5.8/6.8/8.2/10 mm;
Cold water 1.6 Mpa wall thickness: 2.3/2.8/3.6/4.5/5.6/7.1/8.4/10.1/12.3 mm;
Hot water 2.0Mpa wall thickness: 2.8/3.5/4.4/5.5/6.9/8.6/10.3/12.3/15.1 mm.
Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR Pipes has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall, easy construction and maintenance, and long service life. It is widely used in construction, municipal, industrial and agricultural fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid transportation, agricultural irrigation, etc.
Physical properties: Generally speaking, random PP copolymers have better flexibility and lower rigidity than PP homopolymers. They can maintain moderate impact strength when the temperature drops to 32°F, but their usefulness is limited when the temperature drops to -4°F.
The flexural modulus of the copolymer (secant modulus at 1% strain) is in the range of 483 to 1034 MPa, while the homopolymer is in the range of 1034 to 1379 MPa. The molecular weight of PP copolymer material has less effect on rigidity than that of PP homopolymer. The notched Izod impact strength is generally in the range of 0.8 to 1.4 ft·lbs/inch.
Chemical properties: random PP copolymer to acid. Alkali, alcohol, low-boiling hydrocarbon solvents and many organic chemicals have strong resistance. At room temperature, PP copolymer is basically insoluble in most organic solvents. Moreover, when exposed to soap, soap and lye. When used in water-based reagents and alcohols, they are not subject to environmental stress fracture damage like many other polymers.

When in contact with certain chemicals, especially liquid hydrocarbons. Chlorinated organics and strong oxidants can cause surface cracks or swelling. Non-polar compounds are generally more easily absorbed by polypropylene than polar compounds. Its molecules contain only carbon and hydrogen elements, and no harmful or toxic elements exist.
