Food Transfer Hose — Industrial & Food Hose

The product decides. This body has a nitrile tube, which is the compound for fats and oils; the EPDM range is the one for hot aqueous products and dairy. Both run 10 bar working with 30 bar burst across 19 mm to 152 mm, so the difference is chemistry, not pressure.

Yes, because of the spiral steel wire in the reinforcement. A delivery-only hose has no spiral and pinches shut the first time the pump pulls hard, which is the usual reason a tanker unloading line fails. This body is rated 10 bar on both sides.

The 51 mm code is rated 10 bar working (150 psi) with 30 bar (450 psi) minimum burst. Minimum bend radius is 300 mm, mass is 1.93 kg/m, and the coil is 61 m, so a 2 inch order arrives as a 118 kg coil.

20 m3/h is 5.6 l/s. A 2 inch (51 mm) bore moves that at about 2.7 m/s, which is gentle enough for most food products; a 1-1/2 inch bore needs 4.9 m/s and starts to shear the product. The 2 inch row is 1.93 kg/m with a 300 mm bend radius.

2 inch for a tank-to-filler run and 3 inch for a tanker connection: 3.08 kg/m at 3 inch with a 450 mm bend radius. The tube is nitrile at every size, so the bore is chosen on flow rather than on chemistry.

The body takes 10 bar working pressure and the bore drains, which is what a cleaning cycle needs. CIP success depends as much on the ends as on the hose: crimped or clamped terminations leave fewer residue points than a pushed-in fitting with a clip.

Because residue stayed in the bore, not because the compound failed. A 2 inch line at 1.93 kg/m that is not rinsed between products carries taste regardless of the tube. Flush time is the cheapest fix on a filling line.

Either the spiral is missing, which happens when a delivery hose is used on the suction side, or the bend is tighter than the minimum: 750 mm at the 6 inch code and 300 mm at 2 inch. A kinked line does not recover its round bore.

Tube and cover compounds are stated on the sheet, and material documentation is supplied with the order. The range is 9 codes from 19 mm to 152 mm at 10 bar working, all on the same nitrile tube. Where a project requires a specific FDA or EU 1935/2004 declaration, raise it at enquiry stage so the requirement is written into the specification rather than raised at the audit.

YIBO, in Luohe, Henan, builds 9 codes from 19 mm to 152 mm bore on one line, all at 10 bar working with 30 bar burst. Coils and crimped assemblies ship from the same plant, loading through Qingdao or Shanghai.
