Reducing the risk of welding-heat damage to valves during installation

A well known issue related to in-line welding of assembled valves, is the significant risk of damage to the soft parts, seats and seals because of heat transfer from the welding point.

Although the installer should dis-assemble the valve, make the weld and then re-assemble the valve, in reality this doesn’t always happen.

To reduce the risk of damage being caused to valves during the installation process, ESI can now supply Habonim 3-piece ball valves which are fitted with “Extended Ends”.

These valves are available in the 15mm – 100mm (1/2″ – 4″) range, in both full bore and reduced bore.

Standard materials are stainless steel CF3M or Carbon steel WCB (other materials upon request); with end connections design of extended socket-weld or extended butt-weld (sch. 05,10,40,80).

[/fusion_text][fusion_text]The advantages of these new options from Habonim include:

    • Valve integrity is maintained
    • Reduces the risk of improper re-assembly
    • Prevents heat damage to parts that could melt, warp or distort
    • Saves installation time
