Shandong PPR pipes and the traditional cast iron pipe, galvanized steel pipe, cement pipe and pipe compared with energy saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall scale, construction and easy maintenance, long life and other advantages, widely used in construction to drainage, urban and rural areas to drainage, city gas, electricity and cable sheath, industrial fluid transportation, agricultural irrigation, construction, municipal, industrial and agricultural areas.
How to identify good Shandong PP-R pipe
appearance
Color, good PP-R tube soft color uniform, no noise.
texture
Good Shandong PP-R pipe 100% is PP-R material (without any material) to add texture, pure, smooth surface, feel soft, smooth pseudo PPR pipe handle, generally speaking, rough particles is likely to admixed impurities;
smell
Shandong PPR pipe is the main material of polypropylene, pipe does not smell, bad smell, is likely to is the admixture of polyethylene, polypropylene;
hardness
PPR pipe with a considerable hardness, can be easily squeezed deformation of the tube, certainly not R - PP tube;
wall thickness
Also can be measured with a vernier caliper, pipe wall thickness is up to standard and uniform, the general good tube are strictly according to the national standard production, but this method requirements have a certain understanding of PPR pipe national standards.
voice
PPR pipe landing sound more boring, pseudo PPR pipe landing sound more clear.
elastic
The PPR pipe, "resilience" good, easy to smash the nature is not good of PPR pipe, but the temperature is below 10 degrees to the PPR pipe can also smashed. But strong hardness does not mean good elasticity, some manufacturers by adding too much calcium carbonate impurities such as to increase the hardness, how hit is not broken, with a long time easy to brittle fracture; (because PP-R material of cold brittleness are different in some temperature interval performance
Are good Shandong Jianlong Plastic Co., Ltd. focus on 30 years of water supply pipe suppliers, the production of Shandong PVC pipe, Shandong PVC pipes, PVC drainage pipe in Shandong, Shandong PP--R pipe, PVC-U pipes, pipe fittings products to meet the PVC-U water supply pipe implementation of GB / T 10002.1-2006 standard ", conforms to the trend of historical development.
