Pipe internal layer structure engineering at present,The pipe internal layer engineering Articles the gas pipe internal layer of drag reduction engineering in Europe and the United States developed nations has been commonly found in pipe market, like, Canada and Germany has generated large size pipe, spray on the internal wall of the pipe, epoxy layer, in order to decrease the friction of gas transportation. To help make the internal layer of drag reduction engineering in pipe reflect its great faculties in the particular function, we should fix value to pipe internal layer, as the pipe internal layer is a critical engineering of the internal layer structure, internal layer quality may immediately effect on the efficiency of the internal layer engineering and support life. Could be accomplished just the utilization of advanced and reliable engineering, good quality of layer material pipe, and effectively expand the support life of pipe, greatly enhance the effectiveness of the pipe generation work after.
Pipe internal layer engineering research starts late within our state, especially in cross country, large size gas pipe design has not even been application instances, to strengthen the research. As astringent NingLan, zhong wu, west to east gas pipe size for the structure of gas pipe, internal layer drag reduction engineering will get marketed, thus, must cautiously examine and grasp the layer engineering of internal layer, strictly get a handle on the quality of the layer method, promote the application of internal layer engineering within our country.
The internal layer engineering Psinmo in the home and abroad, the development level of the pipe layer method and gear is by using the development and application of varied anticorrosive films in and constant development. Tennessee gas pipe in 1955 for initially in realistic application of layer material pipe. Following decades of development, with the realistic price of the newest engineering and new engineering seem constantly. Many international famous material pipe plant and pipe structure design business has accumulated rich realistic experience, including the German mannesmann, Western NKK and Dutch Selmers, NOVA, Canada, the United States of CRC and Singapore BrederoPrice business, has a complete and suitable for various pipe size and length of area pretreatment and spraying generation point, and have many years of structure experience and great performance. Overall, international businesses in layer generation point complex stage is more than domestic, and its high degree of automation gear, low failure rate, trouble-free function time is long, broad acceptable size selection and the overall layer quality is reliable. For the Western material pipe (NKK) flow chart of the internal layer carbon material pipe.
