New Generation of Quake-Resistant Pipe (Q.R.Flex)

Insurance for the water future

Q.R.Flex

Q.R.Flex pipe is the most recent Hanyco’s product. Q.R.Flex is a push-on flexible restrained joints so that it needs an assembly force similar to Tyton joint, making the assembly very easy. One of the unique specifications of  Q.R.Flex pipe is its proper angular deflection and axial movement.

Q.R.Flex benefits from the normal Tyton gasket for sealing, that it makes installation much easier and faster. A ductile iron locking ring, inserted through a slot in the bell face, provide a positive axial lock between the bell interior surface and a retainer weldment on the spigot end of the pipe.

Q.R.Flex resistant joint provides a chain structure along the pipeline so it can distributes the created forces

in different points along the pipeline.

Standards

::  Q.R.Flex is designed according to ISO 16134 and performance tests were done according to ISO10804.

::  Applying external coatings according to ISO 8179 and internal lining according to ISO 4179 and EN 598.

::  Q.R.Flex is manufactured according to ISO 2531 or EN 545.

::  Sealing gasket is similar to Tyton joint, following ISO 4633 and EN 681.

Applications

:: Suitable for all types of soils and grounds especially regions having unstable soil or marshes.

:: Regions where installation of inhibitory concrete block is impossible.

:: Suitable for trenchless application systems especially horizontal directional drilling.

:: In high-steep and hilly regions.

:: On faults and earthquake-prone regions.

Advantages

::  Improving pipeline resistance against thrust forces and joint protrusion and creating a chain structure in pipeline.

::  Reduction execution costs due to needing no shock-absorbing and cement thrust blocks.

::  Easy and quick assembly operation without any gland, bolt and nut.

::  Increase the water networks safety against earthquake and land sliding.

::  Considerable reduction of loss-water in transferring pipeline and distribution networks.

Dimensions and weights specifications of Q.R.Flex pipes according to ISO 2531 Standard

QR.Flex ON 150-600 mm in K Class-ISO 2531:1998

The weight of locking ring is not calculated in final Q.R.Flex pipe's weight. All dimensions except pipe length are in mm and weight are in kg. Dimensions and weights are mentioned without tolerance consideration. All weights are calculated based on the K9 thickness class. In case of other thickness classes, please contact Hanyco technical experts. Cement thickness in various sizes is similar to Push-on joint (Tyton) pipe.

QR Flex ON 150-600 mm in C Class-ISO 2531 2009

The weight of locking ring is not calculated in final Q.R.Flex pipe&;s weight. All dimensions except pipe length are in mm and weights are in kg. Dimensions and weights are mentioned without tolerance consideration. All weights are calculated based on the preferred pressure class. In case of non-preferred pressure classes, please contact Hanyco technical experts. Cement thickness in various sizes is similar to Push-on joint (Tyton) pipe.
