Kolling standpipes are manufactured from Aluminum Alloy or Copper Alloy to the highest standards to ensure maximum performance and durability. They are used to connect onto pressurized water main supply through the underground hydrant valve. The inlet or base of the standpipe can be manufactured to suit a variety of hydrant connections, but is normally supplied with a female round thread or V thread capable of engaging with a fire hydrant complied to BS 750.
Standpipes are available in single or double outlet 65mm female instantaneous to BS 336 and are connected to the shaft with a 65mm Male and Female Instantaneous (Double pull Release Type), or a swivel gland that will allow continuous rotation of the head through 360 deg. The head with an instantaneous connection may be removed but the swivel type is an integral part of the standpipe. Double outlet standpipe is supplied with a single 65mm male blank plug.
Other connections for Inlet, Outlet and the length of shaft are available upon customer requirement.
