Tevi rezistente la presiune
Technical description Our offer PVC-U pipes in three ranges of working pressures: 0.6, 1.0 and 1.6MPa. The pressure pipes are produced of PVC by means of extrusion with such additives as stabilizers, dyes and lubricants. The pipes are available in ash colour, with smooth external and internal surfaces.
On one end the Ø63mm pipes are provided with a socket having a groove to accommodate a rubber gasket, which is a joining and sealing element and is made of a specially profiled rubber. The gasket is placed in the groove on the socket. This joint is a detachable solution that allows moving the pipeline sections to compensate for any pipe elongations. The PVC-U pipes can also be joined with traditional pipes (cast iron, steel).

Gasket ring joints |
After cleaning the pipe socket, place the gasket in the dry groove with the thicker part backwards. To facilitate this, make the gasket ring into a “figure-of-eight” shape. Then, clean the outer surface of the spigot pipe end. To increase the slip, apply a lubricant agent to this pipe end and make the connection by pressing the pipe into the socket to a proper depth. Detailed data related to pipe connection and placement is provided in the Installation Instructions which is sent upon request of a customer. |
PVC-U pressure pipes, GW type |
We work with manufacturers of GW-type PVC-U piping systems used for the construction of underground pipelines and pipe networks in the areas affected by mining activities. Modified socket depth allows the GW-type PVC-U pipes to be installed in the areas exposed to continuous deformation, intensity of which corresponds to the 4th category of terrain. Standard pipe length for all operating pressure ranges is L = 6 m + 0,02 m. For Ø63 mm up to Ø450 mm pipes an thermoplastic rubber seal is used (EPDM). Note: When installing the GW-type pipeline of the range of nominal diameters from 160 to 450 mm, the direction of the gasket installation is reversed. For diameters from 63 to 110 mm, the gasket is installed in the traditional way. PVC-U stopper ring - drawings and technical data.
Note: For pipe diameters 500 and 630 mm, there is used a gasket with an internal split retaining ring, to be installed at the factory. |
