Hira Industries has just launched a new product range of Diamond expansion joints and piping accessories to complement the highly successful range of Diamond pipe supports which are already available.
The products include flexible pipe connectors and flexible expansion joints used at the inlet and outlet of fan coil units, air handling units, chillers and condensers.
The flexible pipe connectors are available in sizes from ½” upto 2 ½”, with Epoxy coated forged steel triangular head design flanges.
Moreover, the bellows are constructed from Neoprene/EPDM or NBR material with a Nylon Cord Fabric Reinforcement.
For sizes 2 ½” and above it is recommended to use the flexible expansion joints which are made using floating forged steel drilled to BS 4504 PN 16. The Neoprene / EPDM/ NBR bellow are reinforced with nylon cord fabric and spring steel wire.
In any piping installation, the connection of non similar metals is critical. Most metals exhibit very different characteristics such as corrosion and exposure to stray currents.
For example steel reacts with the atmosphere more than copper. Therefore is it recommended to use Di Electric Unions to connect non similar pipes.
The di electric coupler sleeve and the separator gasket in the Di Electric union prevent metal to metal contact thereby protecting the joint and enhancing the life of piping installations.
The Di Electric unions are available in sizes from ½” to 2” withall possible combinations of Male/ Female Thread and solder connections. Visit www.rhira.com
