Pipe P2ES-12
Electrically conductive pipes made of polyethylene composition
Tompolen P2ES - 12, Tompolen P2ES - 22
Application area:
Electrically conductive pipes are intended for the installation of charging hoses used for pneumatic transportation of explosives in the mining industry in all climatic zones of the country in the temperature range from minus 40 ° C to plus 40 ° C.
The use of electrically conductive pipes made of polyethylene composites of the brands Tompolen P2ES - 12 and Tompolen P2ES - 22, in comparison with metal ones, gives the following undeniable advantages:
1. High manufacturability when laying flexible pipes, facilitating assembly / disassembly of the explosives supply system;
2. Light weight facilitates transportation and handling, which reduces the cost of these activities;
3. Resistance to mechanical damage and corrosive effects, both from the transported explosives and from the external environment, provides an increased service life;
4. When using this type of pipes, the need for hot work is eliminated, which helps to reduce the risk of dangerous situations in mines and closed rooms.
Brief product information:
Electrically conductive pipes are made of polyethylene compositions of the Tompolen P2ES - 12 and Tompolen P2ES - 22 brands. The pipe designation consists of the product name, the numerical value of the pipe diameter, the code designation of the electrically conductive composition and the designation of technical conditions.
