Quality problems in connection and construction of steel strip and pipe
clicks: 2214 作者:未知
At present, the plastic pipe market is not standardized, and the connection products of steel reinforced polyethylene spiral corrugated pipe are no exception. There is no industry standard for heat shrinkable pipe and electric heating pipe used by steel belt pipe manufacturers. The units producing connection parts do not know enough about the characteristics of PE pipe, lack of different products adapting to the structural characteristics of different PE structure wall pipes, and lack of high-quality products to meet the requirements of use. To ensure the quality of the connection. It is suggested that strong production units of connected products should participate in the 8219
According to our understanding, there are many problems in the quality of construction operation of steel strip pipe connection. Generally, the mechanism of PE pipe connection structure is not well understood, and the structural characteristics of different wall pipes are often neglected. There is a lack of operation procedures verified by connection quality, and operators can not grasp the temperature well.
From the above several connection technologies, we can see that although the connection construction is not a very complex technical work, the quality of the connection has a great relationship with the quality and working attitude of the construction personnel. The management of the connection construction personnel should be strengthened. All the employees must undergo technical training and pass the examination to be certified.
We believe that the industry should attach great importance to the quality of sewage pipe materials and sewage pipe connection technology. The key to promote the development of new pipelines is to solve the quality control of the production and on-site operation of the connecting parts.
