Material quality of augers pipe is the same as the steell drill pipes which means that the casing tubes and auger pipes are able to with stand heavy stresses .
auger pipe
The flight augers pipes are available with threaded tool joints or hexagonal couplingea.
As a conveyor is either right hand or left hand, depending on how the helical flighting is form ed the hand of the auger pipe may be clearly and easily ascertained by looking at the end of it.
An auger pipe which has the helical flighting wrapped around the pipe in a counter-clockwise direction is arbitrarily termed a left hand auger pipe.
An auger pipe showing the helical wrapped around the pipe in a clockwise direction is termed a right hand auger pipe.
An auger pipe viewed from either end will show the same configuration .
If the end of the auger pipe is not readily visible, then by merely imagines that the flighting has been cut and the cut end exposed, the hand of the auger readily may be determined.
The O.D surface of the auger pipes leads the I.D.surface by up to 25 degrees.This stile of auger reduces O.D.wear and grain damage.It also increases the flow rate of free flowing materials.
The auges pipes are made whih helicoids flights, formed from a flat bar or strip into a continuous
helix.This flithing is thinner in the inner edge than on the outer edge.
At the end of the auger pipe a couple of tool joints is friction welded, thanks to a procces which makes possible to assure a continuosus flight of the helix when the pile is mounted .The tool joints can be both theaded joints or exagonal coupling and they are heat treated in order to assure a resistance to wear and grip.
