What is a duck foot bend?
This invention relates to pipe fittings, and more specifically to pipe fittings known as duckfoot bends. There is a need to bring a water supply to the surface at various strategic locations in water systems involving underground piping of water to domestic or industrial areas. Thus, you should get your duck foot bend malaysia today. A duckfoot bend for a water supply system composed of first and second integral pipe sockets of an appropriate plastics material and at the required angular disposition, said integral pipe sockets being appropriately attached or integral with a foot member, each of said first and second sockets having an internal electrical winding, said windings being connected to terminals externally of the said socket, and whereby with a mains pipe of a compatible plastics material inserted. The application of current to the windings causes the melting of the interface of the duckfoot socket to the mains and to the spigot of the flange piece, resulting in fluid-tight welding of the duckfoot to the mains and the spigot.
Benefits of using a duck foot bend
Duckfoot bends must, of course, have a watertight connection to the mains and a watertight connection to a flanged spool piece, which is difficult to achieve conventionally in the tight confines of a narrow trench. Similarly, and given that there can be a rise and fall at the land surface as between the locations of hydrants in a supply system, a variety of spooled flanges must be transported from which a required size can be selected to set the hydrant tee as required, and as previously mentioned. The convention’s first goal is to provide a duckfoot bend that avoids the disadvantages mentioned above. A second goal is to make it easier to set a hydrant at the correct depth than was previously possible. A duckfoot bend for a water supply system, according to a first aspect of the present invention, consists of a first and second integral pipe socket of an appropriate plastics material and at a required angular disposition, said integral pipe socket being appropriately attached or integral with a foot member, each of said first and second socket having an internal electrical winding, said windings being connected to terminals externally of the said socket, and whereby with a current is applied to the windings, it melts the interface of the duckfoot’s socket to the mains and to the spigot of the flange piece, resulting in fluid-tight welding of the duckfoot to the mains and the spigot.
A spigotted flange piece for use with the duckfoot as defined above, according to a second aspect of the invention, comprises a spigot of a length longer than the typical depth below ground of mains supply, and whereby, on site, a spigot can be cut to any particular length such that when connected to the duckfoot, its flange is at a depth below ground to locate a hydrant at the predetermined depth below ground. There are numerous advantages provided by the invention. There is the ease of installation, as well as the substantial guarantee of a watertight connection between the duckfoot and the spigotted flange piece. There is no need to carry a variety of spooled flange pieces to accommodate all mains depths that may be encountered.
