Quick installation of aluminum alloy piping why? Because for line loose set of expansion joint, flange connection, and directly welded connection mode, as long as the joint of a little common sense should be clear, will be a good time expansion joint welding is definitely use flange connection several times more than a dozen times, even, it is clear that the expansion joint in the form of welding connection can be very time consuming.

AIRPIPE full performance compressed AIRPIPE system, using proprietary technology, can be suitable for pressure, low cost and beautiful appearance to bring high efficiency, high quality compressed air. At the same time, the full performance compressed AIRPIPE system makes the design and selection of spare parts more flexible and easy to install, which can meet all the design and production requirements of different customers.
A device for conveying gases, liquids, or fluids with solid particles connected by pipes, pipe couplings, and valves. Usually, the fluid flows from the high-pressure part of the pipeline to the low-pressure part after being pressurized by blowers, compressors, pumps and boilers. It can also be transported by the pressure or gravity of the fluid itself. Pipelines are widely used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.
A pipe may be subjected to a variety of external forces, including its own weight (pipe, valve, pipe coupling, insulation, and fluid weight), fluid pressure thrust at the pipe end, snow load, soil pressure, thermal stress due to thermal expansion and contraction, vibration load, and earthquake hazards.
To ensure the strength and stiffness of the pipe, the manufacturer must install various supports (hangers), such as movable supports, fixed supports, guide supports and spring supports. The setting of bracket depends on the diameter, material, wall thickness and load of the pipe. The fixing bracket is used to segment control the thermal elongation of the pipe so that the expansion joint works evenly. The guide bracket enables the pipe to move only axially.
