There are many glass pipes used in underground pipes, of course, some of the problems span pipeline beneath the span will be carried out on relatively calculated. Underground pipes with pipe racks, hangers, brackets to support, the distance between two supporting points is called a pipeline span, of course, the span is not too large it will affect the normal operation of the pipeline, if the span is too small, this will Let piping intensive, and the corresponding investment costs would increase because of the increased amount of the pipeline, which zaoqiang FRP cable pipe, in order to ensure safe and proper operation of the pipeline, of course, possible to expand the span of the pipeline problem. Of course, if you want to solve this problem span is determined by the strength and stiffness of the two conditions pipeline: (1) determine the conditions determined by the strength of the pipeline span external loads, pipe interface to generate the maximum stress shall not exceed the allowable stress glass pipe. (2) Press the pipeline span pipeline installation requires a rigidity condition, pipe before installing the equipment to deal with spout, embedded parts, reservations concerning the pipeline installation holes, steel, etc. for review. 2, the slope of the pipe shall require drawings adjust seat adjustment method can be used to achieve the grade requirements Shanxi FRP cable pipe welds should be set for easy maintenance, observe the place. Line 3, and transmission equipment connected internally to deal with clean before installation, welding should generally be fixed nozzle away from the machine to avoid welding impact of stress on transmission equipment installation precision. 4, before the pipe connected to the machine, should prevent a strong hand, check the flange in a free state parallelism and concentricity. 5, high pressure safety valve should be installed vertically FRP cable pipe, put into trial operation, a timely adjustment valve. The final adjustment valve on the system, opening and reseating pressure to comply with the provisions of the design documents. 6, before the valve is installed, according to the design file to check its model number, and press media flow to determine its mounting direction. When the valve flange or threaded pipe connected to the valve should be installed in a closed state; such as by welding installation, the valve can not be closed. 7, the temporary replacement instrument components: all instrumentation components to install FRP cable pipe, are used to replace the temporary elements, and other pressure test, rinse, after the purge job, formally installed before feeding again.
