Application And Characteristics Of Tubes

Jul 01, 2017

    A pipe is a device for conveying gases, liquids, or fluids with solid particles, connected by pipes, pipe couplings, and valves. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and flows from the high-pressure of the pipe to the low-pressure place, and can also be transported by the pressure or gravity of the fluid itself. Pipelines are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.Tube
   The strength and tightness of welded joints are the best, suitable for various pipelines, provincial materials, but must be cut off when the pipe and pipe joints. The city's water supply, drainage, heating, gas supply pipelines and long-distance oil, gas pipelines are mostly laid underground, and the factory's process pipeline for easy operation and maintenance, more laying on the ground. The passage, support, slope and exhaust, compensation, heat preservation and heating, anti-corrosion and cleaning, identification and painting and safety of pipelines are important problems whether laying on the ground or laying underground.
Pipelines on the ground should avoid crossing roads, railways and waterways as far as possible. When crossing is unavoidable, the crossing height should also allow the pedestrian and the vehicle to pass safely. Underground pipelines are generally laid along the road, maintaining a suitable distance between the various pipelines for installation and maintenance; The surface of the heating pipe has an insulating layer, laid in a trench or protective tube, and should be prevented from being crushed by soil and allowing the tube to swell and move.Tube
   Pipelines may withstand many kinds of external forces, including their own weight, fluid action in the pipe end of the thrust, wind and snow load, soil pressure, thermal stress caused by expansion and contraction, vibration load and earthquake disaster. In order to ensure the strength and stiffness of the pipeline, all kinds of support (suspension), such as movable bracket, fixed bracket, guide bracket and spring bracket, must be set up. The bracket is set according to the pipe diameter, material, pipe wall thickness and load conditions. The fixed bracket is used to segment the heat elongation of the pipe to make the expansion joint work uniformly Tube
