Detailed Product Description: | We are of the PP-R pipe inspection specifications and dimensions, pipe nominal diameter, outer diameter and an average thickness of substandard conditions have occurred. Nominal diameter, the average diameter of qualified or not the application and impact of pipe construction quality, size and dimensions indicators of failure are not well connected pipe and pipe fittings, and may reduce the compressive strength of the connection, leaving the pipeline rupture and leakage risks. Will also affect the quality of the wall thickness of the physical and mechanical properties of the pipe. 1. Causes of PP-R pipe extrusion Canadian soil in the process, in the vacuum forming, vacuum control its proper or not, will directly affect the dimensional accuracy of the pipe. Vacuum level is too low, lack of tube adsorption, easily deformed tube, leaving the nominal pipe diameter, the average diameter and wall thickness errors. Extrusion and pulling speed directly affects the pipe wall thickness, dimensional tolerances. Extrusion and traction too fast, resulting in a negative error ppr pipe wall thickness pipe manufacturers, extrusion and traction is too slow, resulting in a positive error pipe wall thickness. 2, the vacuum control measures to adjust the vacuum stereotypes and stabilized at the best value, and the degree of vacuum sealing performance control and vacuum tank vacuum are closely related. Control eliminates the instability factor extrusion system to ensure accurate constant extrusion speed and traction. Anhui Xinhua College PPR pipe explain how to identify the pros and cons of the people PPR pipe used today are more and more, produce more and more manufacturers are also ppr tube top ten brands, however, because of the different materials ppr pipe fittings even when the immediate circumstances of individual manufacturers cut corners in order to have occurred, PPR pipe produced quality is uneven, following on to introduce how to identify the merits of PPR pipe. The first is expected to tell by looking at the method, a good PPR pipe, looks very bright colors, there are oily feeling bad because of PPR pipe materials which got into some bad plastic as well as lime powder these, so PPR tube unnatural brilliance, the incision is also very dry PPR pipe no oily feel and look like a chalk like added. The second is the PPR pipe can touch, but also of PPR pipes inside and outside are very smooth, no uneven, there will be no cracks, poor PPR pipe may not so smooth, pipe surface irregularity . The third is by Dian Dian quality PPR pipe, PPR pipe weight than the poor little good pipe ppr pipe, metal pipe fittings PPR good because generally have more than three or more pieces of copper water seepage trenches, and copper content is relatively high, copper is relatively long, relatively thick, so good quality PPR pipe fittings will be slightly heavier. Fourth, can be tested by burning method. Good PPR pipe materials in more than eight Baidu flames when oxygen is sufficient if it wants off, yes yo ah release carbon dioxide and water vapor, and off when there is no other taste and waste generated by the difference The PPR pipe because there are other really mixed plastics and magazines, there will be another flavor and debris off after generation, this can cut a small slice in the PPR pipe with a lighter to extinguish distinguish. ppr tube top ten brands | in cleaning pipes (certified) | Zhengzhou ppr pipe supplied by Zhejiang Jie Pipeline Co.
