Pipeline installation requirements 1, piping before installing equipment to deal with nozzle, embedded parts, reserve covering pipe installation holes, steel, etc. are reviewed. 2, require pipeline slope should be adjusted drawings, methods can be used to adjust the seat to reach grade requirements, the weld should be set in easy maintenance, observe the place. Pipe 3, and transmission equipment connected internally to deal with clean before installation, welding fixed nozzle should generally be away from the machine in order to avoid stress on the drive impact welding equipment installation precision. 4, pipe connected to the machine before the glass pipe, should be prevented relatively strong, check the flange in the free state of parallelism and concentricity. 5, the valve should be installed vertically glass pipe manufacturers, put into trial operation, to timely adjust the safety valve. The final adjustment valve on the system, open and back seat pressure to comply with the provisions of the design documents. 6, before the valve is installed, according to the design file to check the model and press media flow to determine the mounting direction. When the valve flange or threaded pipe connected to the valve should be installed in the closed state; such as by welding installation, the valve may not be closed. 7, a temporary replacement instrument components: all instrumentation components installed, are used to replace the temporary components, such as pressure test, rinse, after the purge job, then formally installed before feeding. With the application and popularization of glass pipe, glass pipe has basically replaced the cement pipe RPMP depth of all walks of life in the field, not only the glass pipe used in the field of transport raw sewage water, was also used in the field of rail transportation. FRP application development on the rail from the FRP fiberglass parts to the whole head, cabinet and so show a huge advantage and broad application prospects in the field of rail transportation. In addition to the domestic application of existing technologies and processes 100 glass pipe, rail vehicles for R & D, the body interior parts and equipment, facilities, in-depth study should have glass manufacturing technology and the bulk of the products with independent intellectual property and the promotion of high-speed rail career development. At present, China is in a period of prosperity rail transit construction, has become the world's largest urban rail transport market. For fiberglass, this is a promising application areas, the industry should seize this opportunity to continue to develop new products and expand FRP composite materials in the field of rail transportation. At the same time, the development of national energy conservation policy and new energy electric vehicles, as well as the development trend of lightweight automotive materials, glass and steel products for use in the car to provide a broader market space.
