What is the difference between HDPE pipe and aluminum plastic composite pipe?
Also known as the PAP pipe plastic pipe, is composed of a central longitudinal welding tube, inner and outer layer of polyethylene plastic and between layers of hot melt extruded compound into a new type of pipeline, classified by use of ordinary drinking water, high temperature pipe, gas pipe, pipes, features and applications are as follows: the aluminum-plastic composite pipe with the ordinary drinking water application scope: white L logo, living water, condensate water, oxygen, compressed air and other chemical liquid pipeline. High temperature resistant aluminum plastic composite pipe: red R mark, mainly used for long-term work, water temperature of 95 degrees of hot water and heating pipe system. Gas aluminium plastic composite pipe: Yellow Q mark, mainly used to transport natural gas, liquefied petroleum gas and gas pipeline system.
HDPE pipe is high density polyethylene pipe, mainly used for water supply system of municipal engineering, building water supply system, water supply system and outdoor underground residential area, the buried water supply system, pipeline rehabilitation, water treatment engineering pipeline system, landscaping, irrigation and other fields of industrial pipe etc.. But it should be noted that the HDPE pipe cannot be used for hot water lines.
