Detailed Product Description: | PPR pipe which will be on the size of the quality problem? Here is an explanation for everyone OBAMA made for the article for study and reference! Please contact the administrator to correct any objections goods explore! Everyone in the specification of PP-R pipe material test in ppr pipe fittings, pipe public that the average outside diameter and wall thickness does not meet the standard conditions have appeared. And the average nominal outside diameter is not in line with the quality standards would interfere with the use and construction of the pipe, specifications and index size does not meet the standards of the pipe and pipe fittings ppr pipe connecting very well be, but will reduce the coupling position of compressive strength, resulting in burst pipes and leaks have a potential concern. Quality wall thickness will also interfere with the physical and mechanical properties of materials on the pipeline. When PP-R pipe material is pressurized molding manufacturing process, under the vacuum conditions stereotypes, it's vacuum pipe ppr the good and bad of the top ten brands control the situation, it will directly interfere with the specifications of the pipe degree of precision. Such as vacuum degree is too small, not enough power absorption tube, the tube can easily change shape on ppr tube, pipe and let the public that the average outside diameter and wall thickness error occurs. Extrusion and traction direct interference error rate as well as the wall thickness of the specifications on. If you squeeze and pull too fast, it will lead to the thickness of the wall of negative error condition, if it is too slow, it will lead to the thickness of the wall of the phenomenon are errors. The vacuum of adjustable and secured to the best value, vacuum control and the closed state of the vacuum tank and pump performance is closely linked. Regulation and clear extrusion system unstable factors to ensure its accuracy level remains constant. PPR pipe look discolored, uneven color distribution what is the reason? PPR pipe is now more common to use a pipe, PPR pipe usually use them in the form of appearance of brilliance is diverse, and some will be part of the local color of the pipe, or some spots, color is not very uniform, and some may look back to the relatively dim light or brightly lit massive out there. Physical and mechanical properties of these pipes are not standard, and in the course may be split. So cause discoloration, resulting in the appearance of uneven color what reason? First PPR PPR pipe is made of resin through the extruder became extruder is to allow PPR data from the crystal plastics into high-elastic state, put it in a plastic of the molten viscous state, there will be changes in terms of the molecular configuration of the raw material if the PPR received bad heat and pressure, when the extrusion molding, the raw material will change shape when. If the plasticizing temperature is too high, the situation will be the destruction of the molecular structure and color will occur. Also out too quickly, in the barrel of a conflict which has a relatively high heat when the temperature will reduce the material to make a change in the color of the material. Zhengzhou ppr pipe _ the clean pipes _ppr tube cleaning Pipeline Co. by Zhejiang Zhengzhou offices. Zhejiang Jie Pipeline Ltd., Zhengzhou Office (www.pprgc.com) strong, credible, Sheung Shui system in Zhengzhou industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead you hand in cleaning pipes and into the brilliant, for a better future! |
