Measures and methods related to how to improve the finished rate of epoxy powder anti-corrosion steel pipe

Buying Tramadol In The Uk In the epoxy powder anti-corrosion steel pipe production operation process, if the operation process is inappropriate method, then the production of epoxy powder anti-corrosion steel pipe to do anti-corrosion again, greatly reducing the efficiency of 3PE epoxy powder anti-corrosion steel pipe is no exception. Industry stakeholders understand that the current factors affecting the performance of 3PE epoxy powder anti-corrosion steel pipe layer is still more, such as the layout of the process, equipment selection, surface quality, heating, coating temperature, cooling, transmission accuracy, material characteristics and testing, etc., poor control will lead to small coating adhesion, too thin, cracking or bubbles and other defects, the strict implementation of norms and scientific methods of operation is essential to control defects and ensure the yield of anti-corrosion pipe.

Epoxy powder anti-corrosion steel pipe On the 3PE epoxy powder anti-corrosion steel pipe anti-corrosion quality, countries are different methods, announced a steel pipe external ring cooling device, cooling effect has improved, but still can not fundamentally overcome the quality defects and weld coating thickness thinning caused by external cooling methods.

Order Tramadol Cod Next Day Delivery It is pointed out that the ideal method to reduce the coating thickness thinning is to cool from the inside of the tube. And the relevant U.S. patent US6270847B1 discloses a steel pipe anti-corrosion internal cooling method, which is put into the pump inside the steel pipe, spraying water to the inner wall of the steel pipe during the rotation of the steel pipe, the cooling sequence of the steel pipe and anti-corrosion layer is: steel pipe, FBE layer, adhesive layer and PE layer. The heat transfer rate of steel pipe is fast, so that the steel pipe and coating can be cooled quickly, and because the cooling process of the anticorrosive layer is from the inside out, the anticorrosive layer is better bonded to the pipe wall when cooling and shrinking, the circumferential stress of the anticorrosive layer is very small, and the thinning of the anticorrosive layer on the weld path is very small, thus improving the quality of anticorrosive and reducing the cost of raw materials. But this internal cooling method is more difficult to achieve.
