Concrete Pipe Weight Calculator
Pick a pipe size (12 to 108 inches) and wall type A, B or C to get the ACPA approximate weight per foot and the total for your length, or enter any ID and wall thickness to calculate the barrel weight in lb, kg, lb/ft and kg/m.
Reinforced concrete pipe (ASTM C76, tongue-and-groove) weighs about 93 lb/ft for 12-inch Wall B, 264 lb/ft for 24-inch, 524 lb/ft for 36-inch and 867 lb/ft for 48-inch Wall B, per the American Concrete Pipe Association table at 150 lb/ft³ concrete.

Dimensional Breakdown
Geometric Relationships & Engineering Bounds
- Diameter relation: OD = ID + 2 × Wall Thickness. Annular area = π × (ID + Wall) × Wall = (π/4) × (OD² − ID²).
- Linear weight conversion: 1 kg/m = 2.204622 lb / 3.28084 ft ≈ 0.671969 lb/ft.
- Density standard: ACPA references 150 lb/ft³ (≈ 2,403 kg/m³) for standard reinforced concrete pipe (RCP). Actual product weight varies with the concrete mix and reinforcement; use manufacturer data for final decisions.
- Joint exclusion notice: Calculations reflect nominal circular barrel only. Bell, socket, spigot, tongue-and-groove joint profiles, gaskets, and embedded lifting anchors are excluded. Certified manufacturer submittals govern lifting, crane rigging, and transportation loads.

Wall A ≈ diameter in feet, in inches; Wall B = A + 1 in; Wall C = A + 1¾ in (small sizes use set minimums). Bell-and-spigot pipe, heavier concrete and thicker production walls weigh more; use the manufacturer submittal for lifting and haul limits.
Quick answer
Reinforced concrete pipe (ASTM C76, tongue-and-groove) weighs about 93 lb/ft for 12-inch Wall B, 264 lb/ft for 24-inch, 524 lb/ft for 36-inch and 867 lb/ft for 48-inch Wall B, per the American Concrete Pipe Association table at 150 lb/ft³ concrete. Weight per foot = 150 × π/4 × (OD² − ID²) ÷ 144 with diameters in inches, where OD = ID + 2 × wall. An 8-ft joint of 24-inch Wall B pipe is about 2,110 lb.

Summary
Round reinforced concrete pipe is sized by inside diameter and wall type. ASTM C76 gives three wall thicknesses for each size: Wall A (about the diameter in feet, in inches), Wall B (A + 1 inch) and Wall C (A + 1¾ inches). This page carries the American Concrete Pipe Association table of approximate weights per foot for tongue-and-groove pipe from 12 to 108 inches, based on 150 lb/ft³ concrete, plus the ACPA large sizes to 144 inches. Pick a size and wall to get the weight per foot, per 8-ft joint and for your run length, or enter any inside diameter and wall thickness (or OD) to calculate the barrel weight from geometry. Manufacturer weights vary with joint shape, concrete density and wall thickness, so use the supplier submittal for lifting and haul plans.
How it works
- Pick the inside diameter and the ASTM C76 wall type (A, B or C) in the size picker.
- Enter the run length in feet to get the total weight in pounds, tons and kilograms, plus the weight of one 8-ft joint.
- Click "Use in calculator" to load that ID and wall into the barrel calculator, or type any ID and wall thickness (or OD) yourself.
- Choose a concrete density (reinforced 2,400 kg/m³ ≈ 150 lb/ft³ by default) and press Calculate Pipe Weight.
- The calculator returns annular area π/4 × (OD² − ID²), volume, total weight and weight per foot and per metre.
Use cases
- Checking the weight per foot of 12- to 108-inch RCP before ordering trucks or a crane.
- Totaling the weight of a storm sewer or culvert run for a bid or a haul plan.
- Comparing Wall A, B and C weights for the same diameter.
- Estimating barrel weight for a non-standard wall thickness or metric pipe.
- Converting pipe weights between lb/ft and kg/m.
