Metal pipes are a five-layer structure consisting of outer and inner layers of cross-linked polyethylene PEX, the average aluminum layer, glued together. Currently, metal-plastic pipes are actively used in radiant heating, hot and cold water, as well as for installation of floor heating. PEX Plumbing pipe are modern, practical and convenient building material, due to its advantages, they are widespread, as in high-rise construction, and individual houses, cottages, renovation and repair offices. The composite structure allows you to combine in one product advantages both metal and plastic pipes. Metal pipes are not subject to corrosion, and sediment on the inner surface, do not allow oxygen and can slow the wear process heating equipment, they have high mechanical strength, characterized by high durability and low hydraulic resistance, and that far from least, maintain a high quality drinking water. Metal pipes can withstand continuous temperature load of up to 95 ° C and operating pressure up to 10 atm. High performance metal pipes can apply them both separately and in combination with other types of pipes.
Pipe connection in two ways: compression PEX fitting and press PEX fitting.

* Clear the ends of the tubes from isolation.
* Cut a 50 mm working tube special Pipe cutting scissors. Cutting made without distortions perpendicular to the pipe.
* Put on a pipe liner retention groove in the direction of the connected fitting.
* Perform flaring tube manual or hydraulic tool (pictured) in two steps: turning the expander tool relative to the nozzle tube, and after the first flaring – 30 ° again.
* Insert the fitting of laminated tube. After a short time (for a maximum d = 110mm – maximum of 3-4 min) pipe fitting tightly crimped.
* Apply the tool to connect smoothly, without distortions.
* Using the PEX tool, Push sleeve on the fitting until it stops.
* Insert the other end of the fitting in a pre-laminated (see p.4) the free end of connected PEX tubing.
* Apply the tool to connect smoothly, without distortions.
* Using a tool Push sleeve on the fitting until it stops.
* Ready connection is absolutely reliable and sealed.
