Pipe twisting

Posted in: , on 29. Sep. 2016 - 08:29

Greetings to forum

I would like to have an update to know the methods and devices to identify excess pipe belt twisting. please guide me on the following.

1. What is the standard allowable twist of pipe conveyor belt especially in curves.

2. What are the methods to identify this excess twist.

3. Are there any devices available to measure the excess twist and communicate the same.

you might want to contact reputable pipe conveyor supplier on this one, as far as I know there's joint developments underway for such devices.

If not applicable, just or your information & my (limited) insight:

at 1.) no standard, just requirements from operation: Keep the pipe running stable and not let it "tilt". Don't loose the tightness / have spillage due to openings in the wrap

at 2. and 3.) optical methods, CCTV cameras / pattern perception technology

However, even if there's "steering devices" to bring a rolled pipe back into correct position which could be connected to the roll identification, it is imo always the aim to stabilize the pipe running such that extra technology would not be needed.

Dear Sirs

Regarding pipe conveyor twisting as a norm it is desirable to say that on the carrying / top belt the belt overlap should be between 10 o'clock and 2 0'clock.

Of course 12 o'clock is perfect and on some short conveyors I have installed it can be 12 o'clock full length without and tracking, but when conveyors are long and with curves they are more instable and need more tracking, they are also more unstable when empty.

When empty on long conveyor it can be possible and not a problem for the conveyor if the overlap is at 6 o'clock (but no further) which I have experienced many times.

When full off material it depends on the material if fluid material then it is best to be as stated above but between 9 o'clock and 3 o'clock may not be a problem.

On the bottom side the belt overlap should stay a 6 o'clock

The most important is that when the belt opens at the tail or head end it opens correctly for material discharge and travel over pulleys.
