Second, the specifications of the pp tube
Specification of Pp pipes pp pipes are divided into five series according to the standard size ratio SDR value: 1 1, 9, 7.4, 6 and 5.
Specification SDR of pp pipe: the ratio of nominal external diameter dn to nominal wall thickness en of PP pipe.
The relationship between the specification SDR of pp tube and the series of pp tubes is as follows: SDR=2S+ 1.
Representation of specifications of polypropylene pipe fittings;
Nominal outer diameter dn of pp pipe fittings? Refers to the nominal outside diameter of pp pipe connected with pp pipe fittings. The wall thickness of pp pipe fittings shall not be less than that of pp pipes of the same series.
Third, pp tube production enterprises

3. Hubei Ding Yu Pipe Industry Co., Ltd. (formerly Wuxue Ding Yu Industry and Trade Co., Ltd.) was established on March 2, 20 10. It is the only comprehensive enterprise specializing in the production of profiled pipe forming machines and various metal profiled pipes in China.
After years of research and development, tackling key problems and debugging by the company's experts, two kinds of special-shaped pipe forming machines were created exclusively in 20 10 (small special-shaped pipe forming machines can process 8-76mm* 0.3-3mm in thickness, and large special-shaped pipe forming machines can process various metal special-shaped pipes with 60-2 19mm* 12mm in outer diameter).
The above-mentioned pp pipe has many characteristics and advantages, which are generally wear-resistant and corrosion-resistant, with relatively low vibration and noise. In addition, the function of frost crack and high temperature resistance also makes the product not expand and contract due to the sharp increase or decrease of environmental temperature in hot summer or cold winter, which will lead to safety hazards such as damage. These make the products widely used in the field of basic building materials, and the application of pp pipes can be seen in both heating pipelines and water delivery equipment.
