In hydronic radiant heating systems with natural circulation of the circulation pressure is measured only in tens millimeters of water. Such small pressure does not allow to arrange the data systems in buildings having a large extent, they also require the use of PEX pipe diameters significant, leading to a large consumption of metal. These [...]

Application of PEX tubing for drinking water
PEX tubing of rectangular and square cross section, commonly used for manufacturing parts having the shape of plane frames, as well as where necessary increased moment of resistance in simple bending, which is very often required in load-bearing structures. Such use of metal shaped tube of square cross section is justified because it has a [...]
PEX Tubing with high resistance to abrasion
Pragma pipe made of PEX block copolymer (PP-b). Temperature range – 60 C ° + 100 C °. PEX (PP) maintains an unlimited number of cycles of freezing. Resistant to acidic and alkaline environments. Differs both high strength and elasticity. Restores a form for short-distorting. Maximum resistance to shock impact. High resistance to abrasion, is [...]
PEX Pipe Pragma
PEX Pipe Pragma (Pragma) – slip-joint pipe with double wall structured, designed for the construction of non-pressure plumbing systems. The method of production – a double Co-extrusion when both manufactured inner and outer walls forming at the exit of the extrude unit. Outer wall – corrugated, brown, that meets European traditional visual identification of the [...]
The system of floor heating with PEX pipes
PEX Pipe production technology of molecular PEX based on cross-linked polyethylene, medium density (up to 0.940 g / cm 3). In this process of merging, t.e.protsess formation of three-dimensional molecular bonds, occurs after extrusion of pipes in a special salt (peroxide) in the bath temperatures around 200 ° C, causing the degree of crosslinking is [...]
Installation of floor heating
Before installing the heating system is placed along the walls of the strip insulation with a minimum height of 5 mm for the insulation around the perimeter of the circuit. The height of the insulation shall not be less than the thickness of the concrete, which will be heating circuit. Then cleared of debris on [...]
Lightweight frozen resist PEX plumbing tubing
Plumbing PEX tubing are lightweight compared with tubes made of traditional materials. plumbing plastic HDPE are five types (SDR26, SDR21, SDR13.6, SDR11, SDR9), the corresponding nominal pressure, ie the internal pressure of water at 20 degrees Celsius, which is plastic drainage tubing HDPE can withstand for 50 years. plumbing PEX tubing – this is the [...]
What can we say about PEX plumbing pipes?
This type of pipe now occupies a leading position in USA and abroad. As raw material for PEX plumbing tubing has long been known in recent years have found wide application of propylene copolymers with ethylene: block copolymers (type 2) and statsopolimer (type 3). The main advantages of pipes copolymers of propylene is a high [...]
