PRODUCT INTRODUCTION
Dry Cement Discharge Hose — 1.73 to 7.27 kg/m at 10 bar
This is a pneumatic cement discharge hose: an NR + BR tube behind an abrasion-resistant wear layer, a high-strength polyester cord reinforcement and an NR + SBR cover, published from 51 mm to 152 mm inside diameter in six codes, all at 10 bar working and 30 bar minimum burst.
There is no spiral wire in this build, which is the point of it: this is a pressure line for blowing cement, fly ash and dry mortar into a silo, not a suction line. That is also why the outside diameter stays tight — 66 mm on the 51 mm bore and 173 mm on the 152 mm bore.
What changes across the six codes is mass and wear layer: 1.73 kg/m at 2 inch rising to 7.27 kg/m at 6 inch, with the layer stepping from 4.0 to 5.0 and 6.0 mm. The coil changes once as well, from 61 m to 4 inch down to 30.5 m on the 5 and 6 inch codes, so a long silo run is planned around the coil before the bore is fixed.

Values are reproduced from the official YIBO product page. DRY CEMENT PIPE — Industrial & Food Hose: psi columns = MPa × 145.038, rounded. DRY CEMENT PIPE — Industrial & Food Hose: Bore 51–152 mm over 6 codes; each row carries its own rating, and the order data sheet governs the batch.
Application & Selection
Suitable for the transfer of abrasive materials such as dry cement, gravel, and lime, as well as rubber compounds. DRY CEMENT PIPE — Industrial & Food Hose covers 51–152 mm across 6 published codes. Its abrasion-resistant wall runs 4.0 to 6.0 mm thick, sized against the sharp silica load of dry cement rather than a generic wear figure.
Across the 6 codes of DRY CEMENT PIPE — Industrial & Food Hose the top figure is 10 bar working against 30 bar minimum burst — 3:1. DRY CEMENT PIPE — Industrial & Food Hose: From 1.73 to 7.27 kg/m over the 6 rows. DRY CEMENT PIPE — Industrial & Food Hose: We crimp and test every build in-house — 6 codes, 51–152 mm. DRY CEMENT PIPE — Industrial & Food Hose starts at 100 m, across the 51–152 mm range.
WHY THIS HOSE
Six Reasons Mass and Layer Decide the Order
A cement line is rated at 10 bar whichever size is chosen, so the decision moves to weight, wear and coil length.
One Pressure, Six Sizes
Every code from the 51 mm bore at 66 mm outside to the 152 mm bore at 173 mm is 10 bar with 30 bar burst, so the bore is chosen for the conveying rate rather than for a pressure class.
Mass Rises 4.2×
1.73 kg/m at 2 inch, 3.18 at 3 inch, 4.26 at 4 inch and 7.27 at 6 inch: the 5 and 6 inch lines are handled with equipment, not by hand.
Layer Steps Three Times
The wear layer is 4.0 mm on the 2 and 2-1/2 inch codes, 5.0 mm on 3, 4 and 5 inch, and 6.0 mm on 6 inch, which is where the extra mass comes from.
Coil Halves at 5 Inch
From 51 to 102 mm the coil is 61 m; the 127 and 152 mm codes ship on 30.5 m, so a long silo run is planned in joined lengths or in a larger bore.
No Wire, By Design
The reinforcement is polyester cord only, which keeps the outside diameter at 66 mm on the 51 mm bore and makes this a pressure line rather than a vacuum line.
Tight Outside Diameter
66, 80, 94, 121, 146 and 173 mm of outside diameter on six bores leaves room in a plant room where a wire-reinforced body would not pass.
CONSTRUCTION
NR + BR, Cord, NR + SBR
Inner Tube
NR blended with BR for abrasive dry media, protected by a 4.0 to 6.0 mm abrasion-resistant layer between 51 mm and 152 mm bore.
Reinforcement
High-strength polyester cord, no wire, which is what makes this a pressure discharge hose at 10 bar with 30 bar burst.
Cover
NR blended with SBR, an abrasion-resistant cover from 66 mm outside at the 51 mm code to 173 mm at 152 mm.
APPLICATIONS
Where Dry Cement Is Blown
Silo Filling
The 102 mm code at 4.26 kg/m, the usual line from a tanker blower into a silo.
Mortar Plant
The 76 mm code at 3.18 kg/m with a 5.0 mm layer, on a short transfer run.
Fly Ash Handling
The 127 mm code at 5.55 kg/m on a 30.5 m coil, where the bore sets the rate.
Bulk Tanker Discharge
The 152 mm code at 7.27 kg/m and a 6.0 mm layer, the largest in the range.
Batching Plants
The 64 mm code at 2.40 kg/m, a 4.0 mm layer for a short weighed transfer.
Site Delivery
The 51 mm code at 1.73 kg/m, the lightest line in the range, for a small mixer feed.
HIGH-END INDUSTRY DIRECTIONS
What a Cement Plant Asks
The questions are about wear life, weight and how many lengths a silo run needs.
① Wear Life per Metre abrasion resistant hose
Trend: Lines are costed against tonnes conveyed.
Dohose: 4.0 to 6.0 mm wear layer by bore.
② Longer Silo Runs cement hose
Trend: Plants push the connection point further out.
Dohose: 61 m to 4 inch, 30.5 m at 5 and 6 inch.
③ Handling Big Bore large bore hose
Trend: 5 and 6 inch lines are moved by hoist.
Dohose: 5.55 and 7.27 kg/m published per code.
④ Plant Room Space compact hose
Trend: Retrofits have a fixed outside diameter budget.
Dohose: 66 mm outside on the 51 mm bore.
⑤ Blower Rating pressure hose
Trend: Blowers run at 8 to 10 bar.
Dohose: 10 bar working, 30 bar burst, 3:1.
⑥ Cutting on Site cut to length hose
Trend: Lines are cut to the silo connection.
Dohose: Cut from 51 to 152 mm bore, ends fitted.
WHY DOHOSE
Seven Reasons Buyers Stay with Us
Numbers, Not Averages
Every figure for the Dry Cement Pipe comes from the per-code table: 51–152 mm, 10 bar working, 30 bar burst.
One Line, Full Range
All 6 codes of the Dry Cement Pipe come off the same line, so a mixed order in 51–152 mm ships together.
Length on Demand
Cut-to-length supply for Dry Cement Pipe; each code carries its own mass, 7.27 kg/m, so lifting gear can be sized first.
Ends Done Here
Assemblies of Dry Cement Pipe are crimped on site and held at test pressure before they are boxed.
Export Packing
Coiled in poly bags, then woven bags on pallets — loading plans are drawn for 6-code orders.
OEM Ready
Brand printing and custom packing are standard options on the Dry Cement Pipe.
Fast, Firm Pricing
A firm price for Dry Cement Pipe usually returns within 1 hour of your enquiry.
FAQ
Dry Cement Hose — Ten Questions
Dry cement hose vs a water suction hose — what is different?
The tube compound and the reinforcement. This one is NR + BR behind a 4.0 to 6.0 mm wear layer with polyester cord and no wire, rated 10 bar, while a suction hose carries a spiral wire to resist collapse.
Can it replace a wire-reinforced suction hose?
No. Without the spiral wire the bore will flatten under vacuum, and this hose is built for pressure conveying only at 10 bar with a 4.0 to 6.0 mm wear layer. If the line is suctioned, the wire-reinforced version at the same bore is the part to order.
What is the rating on the 4 inch code?
10 bar working with 30 bar minimum burst, on a 102 mm bore, a 121 mm outside diameter, a 5.0 mm wear layer and 4.26 kg per metre, on a 61 m coil.
How heavy is the 6 inch code, and how long is the coil?
7.27 kg per metre on a 152 mm bore and a 173 mm outside diameter, with a 6.0 mm wear layer, supplied on a 30.5 m coil rather than the 61 m used to 4 inch.
Will it handle dry cement and fly ash?
Both are inside the published duty: abrasive dry media at 10 bar with 30 bar burst. The 102 mm code at 4.26 kg/m with a 5.0 mm layer is the size a tanker blower line usually uses.
What bore for a 30 tonne per hour silo fill?
Flow at 10 bar is set by bore, and the common choice is the 102 mm code at 4.26 kg/m on a 61 m coil, which covers most tanker-to-silo connections. Moving up to the 127 mm code at 5.55 kg/m adds rate but also drops the coil to 30.5 m, so the run is joined rather than cut whole.
Why is the burst only 30 bar on a 10 bar hose?
Because 30 bar is three times 10 bar, and that 3:1 margin is what the table publishes on all six codes. A cement blower runs well inside 10 bar, so the margin is there for a slug of material rather than for the compressor.
Why does the hose wear through on the outside of a bend?
Because dry media is thrown to the outside wall at every change of direction, and a tight bend doubles the load on the wear layer. On the 152 mm code at 7.27 kg/m a swept support rather than a clamp is the fix, and the 6.0 mm layer is what buys the time.
What is the minimum order?
One coil or cut lengths from a metre across the six codes, from 51 mm to 152 mm bore. The 61 m coil covers 2 to 4 inch and the 30.5 m coil the two largest bores, so a mixed order ships as two coil sizes, packed by bore and marked with the wear layer of each length.
How is the hose priced?
Per metre by bore and by wear layer: 1.73 kg/m at 2 inch against 7.27 kg/m at 6 inch. Send bore, conveying rate, blower pressure, length and destination for a firm figure.
