What is Pipe Line?

Date:2018-04-18    View:656      Tag:What is Pipe Line
Pipes, pipe line, connectors and valves with pipes are connected to the device for transporting gas, liquid or solid particles in the fluid. Typically, the fluid after the blower, compressor, pump, and boiler comes from pressure flow at high pressure in the pipeline, and can also be supplied by fluid pressure or gravity. The pipeline is widely used, mainly for water supply and drainage, heating, gas supply, oil and gas long-distance transportation, agricultural irrigation, water conservancy projects and various industrial equipment.


When the fluid flow is known, the diameter depends on the allowable flow rate or the allowable frictional resistance (pressure drop). The large diameter flow rate is very small, but the pressure drop value increases. Therefore, traffic can save large pipeline infrastructure investment, but the energy cost of running pumps and compressors and other power equipment is increasing. In addition, if the traffic is too large, it may bring some other unfavorable factors. Therefore, diameter should be determined according to construction investment, operation cost and other technical factors.


Pipe, pipe joint, connection method to remove the pressure and temperature between the valve and the equipment, material, size and installation site factors determine the fluid properties of the pipe, mainly threaded connection, flange connection, socket four ways to join and weld.


The city's water supply and drainage, heating, gas pipeline and long distance oil and gas pipelines are mostly laid in the underground, and the factory's process pipes are easy to operate and maintain and lie more on the ground. Channel pipe support, discharge of slope and drainage systems, compensation, heat insulation and heating, corrosion and cleaning, and coating and other safety identification are important issues in both laying and laying.


Surface pipelines, roads, railways and waterways should be avoided. Pedestrians and travel safety shall be allowed when crossing the intersection at a high crossing level. Underground pipes are generally laid on the road to maintain the appropriate distance between the various channels that are installed and maintained; the surface heating pipes are insulated, laid in ditches or protective pipes, and should be avoided to be moved by the smash and the swelling of the dirt.
