MATERIAL SUCTION AND DISCHARGE HOSE

That depends on the vacuum unit rather than on the hose, but the hose sets the limit: a 152 mm bore at 7.27 kg/m holds its shape under a harder pull than a smaller one, while the 51 mm code at 1.73 kg/m is for a short lift from a pit.

The vacuum goes to its maximum in seconds, and the bore is loaded from outside at its worst. The spiral wire is what keeps the 102 mm code from folding; without it the same wall would flatten and the line would have to be stripped to clear.

Same table, different duty. Both are 10 bar over 51 mm to 152 mm, but this one is bought for the intake side, where the load comes from outside, and the transfer version is bought for pushing material into a bin.

10 bar working with 30 bar minimum burst, on a 102 mm bore, a 124.6 mm outside diameter, 5.0 mm of rubber behind the bore and 4.26 kg per metre.

The 152 mm code at 6 inch and 7.27 kg/m, supplied as a 30.5 m piece. A rail wagon is usually the 127 mm code at 5.55 kg/m, on the same piece length.

Yes — that is a 102 mm bore at 4.26 kg/m, with 5.0 mm of abrasion-resistant rubber behind the bore. The material arrives at the intake faster than anywhere else in the line, which is why the wall is thickest where the bore is largest.

No. Without the spiral wire the same 102 mm bore folds the first time the vacuum peaks, and the 10 bar rating says nothing about that case at all. The load is on the other face: a pressure hose is pushed outward, an intake is squeezed inward.

Because more material passes the wall per hour. The rubber behind the bore is 4.0 mm at 51 and 64 mm, 5.0 mm from 76 to 127 mm and 6.0 mm at 152 mm, so the wear allowance grows with the throughput.

One piece, cut to the lift, in any of the six sizes from 51 mm to 152 mm. The four smaller codes come as 61 m coils and the 127 and 152 mm codes as 30.5 m pieces.

Per metre by bore: 1.73 kg/m at the 2 inch code against 7.27 kg/m at 6 inch. Send the material, the lift height, the vacuum unit and the destination for a firm figure.
