Water supply pipe fittings basic knowledge of purchasing
1, plastic composite pipe
Plastic composite pipe is the first alternative to cast iron pipe water supply pipe, its basic structure should be five, that is, from the inside were plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic.
Aluminum plastic composite pipe has good insulation properties, corrosion inside and outside the wall is not easy, due to inner smooth, fluid resistance is small; it as free to bend, so installation is easy for construction. As for
Water pipe, aluminum plastic composite pipe of sufficient strength, but if too much lateral force, it will affect the strength, so should be out or buried in the wall pipe construction, but should not be buried underground. Plastic composite
Tube is ring-type connection, so the construction it is necessary to pass a stringent test pressure, test the connection is solid. Second, to prevent frequent vibration, so that card set loose. Third, the length of the left foot should be
Installed capacity, so as not to pull off.
2, plastic compound copper pipe
Plastic compound copper pipe to copper (copper) for pipe fittings, covered with PE plastic, from the overall performance point of view, better than the plastic compound copper pipe aluminum composite pipe. For example, better strength, life
Longer and have better heat resistance. However, slightly worse thermal insulation properties.
Copper has very high corrosion resistance, used for some time, the inner surface of the green layer of oxide will appear. But for the life of pipe, flow, and fluid resistance, basically
Not matter. Aeruginosa to human health and without damage, and on the ability to kill certain bacteria.
Plastic compound copper pipe installation method and the welded sleeve type two, welded the more reliable.
Brass, stainless steel pipe:
In addition to poor thermal insulation properties of these tubes, other indicators such as strength, fluid resistance and so life well, let cold water pipes should be. Such as for water transportation, additional insulation jacket should
. Connection to the main ring-type, copper can be welded.
Galvanized iron pipes within the slush:
That is, in general galvanized pipe wall sugar layer of plastic, to have corrosion resistance, good insulation properties, but also has its own high strength galvanized tube characteristics. Most of this pipeline
Connect with rib.
Plastic pipe:
Plastic tube as long as the materials used meet the standards, can have sufficient strength, life, safety and health. It is the insulation of all piping in the best performance. Plastic pipe welding using heat
Then high degree of reliability, as long as construction is correct, the normal pressure test the pipeline by welding, leakage will not fall off.
