Natural hazards are inevitable, and generally, the damages and consequences of these hazards impose heavy costs on the infrastructure of areas exposed to these hazards. One way to prevent heavy costs on basic infrastructure when these hazards occur is to retrofit these infrastructures. Earthquake-resistant pipes are humanity's latest solution to minimize the costs of damage to water and sewage distribution and transmission networks after earthquakes and natural disasters. Leading companies in the world have paid great attention to this type of connection. In order to complete its product portfolio and take an effective step towards making the country's water distribution and transmission network more resilient, Hamon Naizeh Company produced its first generation of earthquake-resistant pipes, called earthquake-resistant pipes with R.J Pipe connections, by reverse engineering the American model. Currently, this product is produced from 80 to 800 mm in size. This type of connection uses a sealing gasket similar to the Tyton connection in the sealing section, and the mechanical strength of the connection is also provided by the excess created on the bowl head during centrifugal casting and also the gland installed on the bowl head. This type of connection has a suitable angular and axial deviation, which allows the pipeline to adapt to ground movements by creating a chain structure during subsidence and earthquakes and not to suffer from so-called dislocation. The R.J Pipe connection is designed in accordance with the international standard ISO 16134 and has been functionally tested in accordance with the international standard ISO 10804.

Technical advantages of R.J.Pipe

•Increased resistance to axial forces

•Ensuring the safety of water supply networks against earthquakes and land subsidence

•Suitable assembly and installation speed

•Simplicity and ease of assembly for the customer

•No need for bolts and nuts

•Proper sealing against water pressure

•Ensuring the safety of water supply networks in waterlogged, sloping and unstable lands

•Significant reduction in water loss and reduction in pipeline maintenance costs

Currently, Heniko has been able to cover all the needs of consumers in this field by producing joints with the R.J. Pipe earthquake-resistant connection, along with pipes with this connection.
