Because we are not professionals, we may not understand the installation requirements of FRP ducts. It does not matter, the following Xiao Bian will give you a brief introduction to the installation requirements and functional characteristics of FRP ducts. First, the installation requirements of glass steel pipe 1. Before pipeline installation, check the contents of pipe installation, embedded parts, reserved holes, and steel structures involved in pipeline installation. 2. The slope of the pipeline should be adjusted according to the requirements of the drawings. The adjustment method can use the support to achieve the grade requirements. The weld should be set in a place convenient for inspection and inspection. 3. The pipeline connected with the transmission equipment should be handled cleanly before being installed. The fixed welding nozzle should generally be far away from the equipment to avoid the influence of welding stress on the installation accuracy of the transmission equipment. 4, before connecting the pipeline and the machine, should prevent strong relative, check the parallelism and coaxiality of the flange in the free state. 5, safety valve should be installed vertically, in the trial operation, it is necessary to adjust the safety valve. The final adjustment of the safety valve is performed on the system, and the opening and return pressure must conform to the design document. 6. Before the valve is installed, check the model according to the design document and determine the installation direction according to the medium flow direction. When the valve and pipe are connected by flange or thread, the valve should be installed in the closed state; if it is installed by welding, the valve must not be closed. 7. Temporary replacement of instrument components: All instrument components are replaced by temporary components when they are installed. After pressure testing, flushing, and purging are completed, the instrument is officially installed before feeding. Second, the characteristics of glass fiber duct function 1, has excellent corrosion resistance Do not anti-corrosion protection and other anti-corrosion measures, will not produce secondary pollution of water and other media. Long product life. 2, light and strong Pipe weight only accounts for 1/4 of ductile iron pipes of the same size, same length, and 1/10 of cement pipes. Easy to transport and easy to install. 3, long single pipe length Reduce pipeline joints, speed up installation, and improve overall pipeline quality. 4, smooth wall Reduce flow resistance, increase flow rate, and reduce energy consumption. The use of smaller-diameter pipelines to deliver fluids of the same flow rate can increase the flow rate by about 10% compared with steel tubes of the same size. No fouling and long-term use do not reduce the flow rate. The protection of the cable in the interference and heavy corrosion environment has a good effect. The above is a brief introduction for Xiaobian. If you want to know more related information, please continue to pay attention to Qijia Consulting. More exciting consultation, please stay tuned.

Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.
The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw
