In practice, the selection of the nominal pipe is governed by the required conveyor capacity, belt speed and material properties. Usually the filling ratio of the cross section of the pipe is around 50–60% or even up to 75% . The choice of the pipe diameter needs to be verified with the lump size of …
Nominal Pipe Size (NPS) is a North American set of standards used to designate pipe diameter and thickness. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) for inside diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness.
The nominal capacity of a screw conveyor is determined by the outside diameter, inside diameter and the screw pitch, as well as the operating speed. A typical screw conveyor had a diameter to pitch ratio of 1:1 that is, the screw pitch is the same measurement as the outside diameter …

Key to Conveyor Size Designation The letter “H” indicates screw conveyor with helicoid ﬂighting. The ﬁgures to the left of the letters indicate the nominal outside diameter of the conveyor in inches. The ﬁrst ﬁgure following the letters is twice the diameter of the couplings in inches.
six rolls for pipe conveyors. The Ai factors were then adjusted for the ratio of the pipe conveyor idler roll diameter vs. CEMA standard and for pipe conveyor idler bearing diameter vs. CEMA standard.
Coupling bolts are listed by the corresponding standard conveyor shaft diameter with which they are used. Conveyor pipes are listed in both Schedule 40s and 80s by their nominal pipe sizes. The pipe size selected should correspond to the standards listed for carbon steel pipe.
Nominal Pipe Size and Schedule collectively sets the pipe outside diameter (OD) and the wall thickness (and hence the internal diameter (ID) is automatically fixed). For example, NPS 14 Sch 40 has an OD of 14 inches (360 mm) and a wall thickness of 0.437 inches (11.1 mm).
A 12-inch diameter screw conveyor was selected for the example. The minimum standard shaft size for a 12-inch diameter screw conveyor is 2-inch diameter. The corresponding pipe size is 2-1/2-inch schedule 40 pipe with 5/8-inch diameter coupling bolts. The materials of construction of the screw conveyor is carbon steel.

May 21, 2005· I have come across pipe conveyors ranging from 150mm nominal diameter to 700mm nominal diameter. This will have belt widths ranging from 600mm to 2800mm. Your requirement pertains to what size or capacity? You can also refer to manufacturers of pipe conveyors for specific information or exceptional kind of requirements.
In a screw conveyor, the screw is sized by its diameter, shaft size and length. For screws up to standard length, the pipe size is dependent on the shaft size and is schedule 40. The standard shaft/pipe combination is adequate to handle both the torque and deflection of …
Nominal Wall Thickness for Schedule Sizes. Nominal Pipe Size Outside Diameter ... Outside diameter (mm) minus wall thickness (mm) multiplied by wall thickness (mm) multiplied by 0.0246615 = Kg/metre. OD – WT x WT x 0.0246615 = Kg/m. This data is offered for guidance. For Specific information please refer to appropriate standard.
Nov 02, 2005· Dear Banarjee In addition to Maximum size of lump as indicated by Mr nordell you have to see sieve analyses of material in case maximum lumps are in the range of 25-30 percent than pipe conveyor may be slightly on lower side however percentage of 200 size lumps are more han 70-80 percent you may have to go for sligtly higher pipe diameter.
Dec 04, 2018· The Pipe Conveyor is an enclosed curve going transportation system for all kinds of bulk materials. At the loading and discharging points, the conveyor system is identical with open troughed conveyors.

Some rules of thumb: - The minimum radius of a textile pipe conveyor belt should be 300 times pipe diameter and of a steel cord pipe belt 600 times the diameter. - The pipe diameter should be min. 3 times the lump size. - The filling degree should be between 60 and 75 %. - The flat-to-pipe transition lengths should be min. 55 times pipe diameter.
pipe conveyors or tubular conveyors, high incline or high angle conveyors, wheel-on-rope type of conveyors like cable conveyors and Ropecon. Pipe conveyor was first installed in 1980s in Japan , the actual advantages of using pipe conveyor was its capabiitt to accomplish sharp curves and seal the transporting material.
The following is an overview of how tube and pipe size is measured and handled. OD and Nominal Pipe Size. Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).
