1, multilayer pipe:
Multilayer Pipe, also called multilayer composite pipe MLCP, or composite pipe, has been widely used for hot & cold water plumbing systems, underfloor heating systems & indoor gas distributions.,etc.
Multilayer pipes are a "composite pipe", which are made of composite materials with a five layers' structure. The inner & outer layers are regularly made of PEX/ PERT (or HDPE) material, middle layer is aluminum core, which is welded in a seamless laser welding technology or overlap welding technology. To bond the PEX layers to aluminum layer, a special adhesive shall be used.

3, What's the main difference between butt welding & overlap welding of multilayer pipe?
Butt welding & overlap welding are the most regular welding technology for aluminum core of multilayer pipe.
Overlap welding technology is ultrasonic type welding, by using ultrasonic to weld the aluminum in a overlap way.
utt welding technology, also called "seamless butt laser welding", is to weld the aluminum by laser in a seamless butt welding way.
By comparison to overlap welded multilayer pipe, the laser welded pipe is considered to be more stable on aluminum welding jointing, especially when the pipe is rounded & beveled by reamer, the multilayer pipe with laser welding is no easy to crack off.

Advantages of Our Pipes:
1.High Temperature Resistance: The maximum sustained working temperature is up to 70 Degrees Celsius, the maximum transient temperature is up to 95 Degrees Celsius.
2.Heat Preservation: Low thermal conductivity which is only 1/1500 of brass pipe, and 1/250 of steel pipe.
3.Non-toxic: No heavy metal additives, would not be covered with dirt or contaminated by bacterium.
4.Corrosion Resistant: Resist chemical matters or electron chemical corrosion.
5.Lower Installation Costs: Light weight and ease of installation can reduce installation costs by as much as 50%. over metal piping system.
6.Higher Flow Capacity: Smooth interior walls result in lower pressure loss and higher volume than metal pipes.
7.Long Life: More than 50 years under normal conditions.
