Pipe installation
Ways of spiralnovityh pipes SPIRO
Sewer pipes SPIRO recommended for use in places not exposed to direct sunlight.
For spiralnovitye SPIRO pipes, the following connection methods:
1. Flare connections
Sewer pipes SPIRO spiralnovitye with a nominal inner diameter of not more than 800 mm can be connected to each other into the socket with rubber gaskets that provide a tight seal.
Rubber grommets are supplied with the pipe, standard pipe length is 6 or 12m (other lengths on request).

2. Extrusion welding
Welding SPIRO polyethylene sewer pipes made from the outside by means of an extruder.
For large diameter pipe welding is done on both sides.
This compound has a very high resistance to fracture, and are homogeneous. It is recommended to connect the pipes SPIRO large diameters, as well as the reconstruction of pipeline rehabilitation method.
3. Threaded connection
It is used mainly in the reconstruction of the destroyed pipelines and installation of crossings under roads.
Due to the spiral structure sewer pipe SPIRO, it is possible to make internal and external threads.

4. Screw connection with seal
The use of rubber seals when connecting sewer pipes SPIRO can simplify and reduce the cost of installation of pipelines in the real world.
A rubber seal provides a watertight connection. The speed of execution of tasks on laying of utilities allows to stack large volumes over the same period of time.
5. Shrink tape
Heat-shrinkable tape can be used for the outer seal, and also in combination with other materials. When used for special purposes shrink tape bought separately.
6. Segment bends SPIRO
Plastic connecting pieces of pipe segments made by butt welding. These parts allow to optimize the flow pipe when laying pipelines and reduce construction time.
