Natural gas aluminum pipe, what fittings are best used?
Special pipe fittings for copper plastic aluminium tube.The aluminum plastic pipe is a composite pipe which is welded longitudinally by an intermediate aluminum pipe and is lined with polyethylene plastic inside and outside, and is bonded with hot melt adhesive between the layer and the layer. According to the use of classification, there are ordinary drinking water pipes, high temperature pipes, gas pipes. Gas aluminum composite pipe has yellow Q mark, mainly used to transport natural gas, liquefied petroleum gas and gas pipeline system. Because the middle layer of aluminum plastic pipe is made of aluminum, the permeation of gas on plastic can be avoided, so the utility model is more suitable for gas pipelines.
Aluminum plastic pipe in the installation and use, should try to avoid small radius bending, in order to prevent the aluminum tube part of the rupture; at the same time avoid connecting pipe buried in the wall, underground, in order to facilitate inspection and maintenance.
A pipe fitting is a piece of pipe that is connected to a pipe.The common materials of plastic aluminum pipe are plastic, stainless steel and copper. Because the mechanical strength of metal pipe is usually higher than that of plastic, it is used more in gas system. Because stainless steel products are of great difference in material and properties, copper products with stable performance are usually used without the choice and designation of materials.
