Welcome to inquire! Contact: Fengjing Li. 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, 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 FRP cable pipe, pipe interface pipeline span under maximum stress generated external loads must not exceed the allowable stress FRP pipe . (2) Press the pipe stiffness conditions span fiberglass when RPM pipe installation, some matters need attention, the first thing to note docking pipe butt Shanxi FRP cable pipes, rubber ring of high pressure FRP cable pipe, the installation should be considered temperature changes caused by cold expansion and other issues. Certainly, the most should pay attention to is the Langfang FRP cable pipe, pipe trench excavation work point. Trench surface width should meet the standards. Bottom surface of the trench should be smooth and continuous, not a boulder or greater than 40mm 25mm cusp-shaped gravel direct contact with the tube wall. Trench whether to take support measures should be designed based on factors determined by the construction organization trench soil, groundwater level, slotting section, external load conditions. The support material may be of steel, wood or steel timber mixed use. GRP pipe installation work is most in need of attention to the size of the pipe trench problem. Therefore, understanding the relevant knowledge is more necessary.
