Dear All,

Wich is the diference between EP & PIW ?

PIW = Pound per inch of width of the belt,

For Example:

If i have a 450 PIW, and the width of the conveyor belt is 24", the load capacity of the belt in this width is 10800 pounds,

450 PIW * 24 in of width = 10800 pounds

Is this right ?

Marcos Suarez.

In North America EP stands for the type of carcass construction. E = Polyester P=Nylon. In Europe EP is their version of PIW.

in EP belting the polyester run the long way on the belt which had greater stretch resistance than nylon. Nylon is used across the belt as it has the greater tear resistance.

you may also see NN which stands for nylon nylon construction. EP is more commonly used.

You are correct for what PIW is - it would be best described as the tensile strength rather than load capacity. Load capaicty of a belt means a whole different thing.

You also need to allow for what type of splice you will use mechanical vs hot splice and reduce that strength accordingly.

Thanks Mr Blenkhorn,

But, ¿How i can calculate the load capacity of the conveyor belt, if the data sheet is EP 630/3 for example?

If you mean tensile strength then you can find that answer in this thread. Read the link I posted in post #3.
