Catalogue - Smooth PVC pressure pipes

Poly (vinyl chloride) pipe is obtained by means of an extrusion process consisting of passing the PVC resin, duly added, melted and therefore mouldable, through a nozzle with an annular section, achieving a homogeneous thickness.


PVC smooth pressure pipes are used for water conduits and distribution, conduits for irrigation systems, agricultural installations, conduits for transporting acidic or alkaline solutions, industry, construction, mining, running and insulation of cables, and many other installations related to the water cycle.

Its completely smooth internal surface prevents incrustations and reduces pressure losse. During the installation, the direction of the pipe can be changed at the joint up to the maximum angle indicated by the manufacturer.


Adequa smooth PVC pressure pipe are certified in accordance with the UNE-EN ISO 1452 standard.

Types of pipe unions

Elastic union
It is made through a rubber ring lodged in the tube’s cup. The seal is supplied assembled. We recommend that a special lubricant or neutral soap should be applied to ensure that the tube slides perfectly through the elastic ring. This will facilitate the execution of the joint without producing any displacement of the elastic ring.


Glued union
This type of joint is made by applying a specific adhesive for PVC-U pipes. It is recommended that before applying this adhesive, the elements to be joined are thoroughly cleaned with a special cleaner for this purpose.
