FUEL & DIESEL/GASOLINE SUCTION AND DELIVERY HOSE

Only if the tube is quoted against the blend. The NBR tube here is rated 10 bar working and 30 bar burst on every code from 19 mm to 203 mm, but ethanol content is a compound question rather than a pressure question. Tell us the blend and the duty is confirmed against it, instead of a generic gasoline rating.

The copper wire in the reinforcement, and nothing about the pressure class: both are 10 bar working with 30 bar burst. What changes is the assembly. The wire has to be bonded end to end, so a conductive hose cut and clamped on site loses exactly the property it was bought for.

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 1.98 kg/m, and the standard coil is 61 m, so a 2 inch order arrives as a 121 kg coil.

1000 l/min is 16.7 l/s. A 4 inch (102 mm) bore moves that at about 2 m/s, a 3 inch bore needs 3.7 m/s, and a 6 inch bore drops it to under 1 m/s. The 4 inch row is 5.08 kg/m with a 550 mm bend radius, which is the usual answer for a depot arm.

Yes. Bottom loading is a suction-side duty as much as a discharge one, and the spiral steel wire keeps the bore open while the pump pulls. 3 inch and 4 inch are the working sizes, and the 10 bar rating covers the discharge head at a normal terminal.

That is a compound question, not a pressure question. The body is rated 10 bar with 30 bar burst across the range, but B100 has to be checked against the tube rather than assumed from a diesel rating. Send the blend ratio and the temperature and we confirm the tube before quoting.

Because the charge has nowhere to go. The copper wire only dissipates it if it is bonded through both couplings and the hose is grounded at the truck end. A conductive hose fitted with unbonded camlocks, or a standard hose run at 10 bar on a solvent blend, produces exactly the spark the wire was meant to prevent.

Permeation from high-aromatic blends reaches the cover from inside and softens it, and dragging across the apron does the rest. The NBR plus CR cover resists abrasion better than plain nitrile, but a 4 inch line at 5.08 kg/m left lying in a pool of fuel is being tested beyond its cover.

YIBO, in Luohe, Henan, builds the range on one line: 10 codes from 19 mm to 203 mm bore, 3/4 inch to 8 inch, all at 10 bar working with a conductive copper wire in the reinforcement. Coils and crimped assemblies ship from the same plant.

Price follows bore and ends: 1.98 kg/m at 2 inch, 5.08 kg/m at 4 inch, 12.71 kg/m at 8 inch. The 8 inch code is a 30.5 m coil weighing about 388 kg, so it ships on a reel. Send bore, length, ends and destination for a firm figure the same working day.
