The calculator can be utilized by anyone that knows the loading criteria of their application and whether the tube will be used as a beam or column. This calculator will compute the acceptable Allied galvanized steel tubing product size based on length and load criteria. We will calculate the volume of a 6-meter length pipe, with an inner diameter equal to 15 centimeters. The pipe is used to transport water. Let's put these data into the calculator to find the volume of water in the pipe, as well as its mass. First, enter the pipe's diameter: inner diameter = 15 cm. Then, type in its length: length = 6 m. In case all you want is the length for documentation, you can determine the length by using the Inquire Element and/or the Total Length commands. Jef RE: Solid edge calculating bend tubes The beam calculator uses these equations to generate bending moment, shear force, slope and defelction diagrams. The beam calculator is a great tool to quickly validate forces in beams. Use it to help you design steel, wood and concrete beams under various loading conditions. The length of pipe (arc) in any bend depends on the following: (A) Number of degrees in angle of bend (B) Length of bending radius The length of arc in a pipe bend is measured along the centerline of the pipe. The radius is also measured as extending to the center-line. Use the formula below to calculate arc length. No mater how you slice it, a tube is going to be bent. The process of using a STEP file converter to eliminate data entry errors can go a long way to reducing the cycle time of getting a bent tube off the machine. For a 2 bend part, a STEP file conversion just might be overkill. Hollow Square Tube Deflection = (f x l x l x l) / (t x y x (((s - k 4) 4 /12) - ((s - (2 x k)) 4 / 12))) Where, F = Force L = Length of Beam T = Type of Ends Y = Material Type S = Tube Size K = Decimal Gauge Copper Tubes - Pressure Loss in Fittings and Valves Expressed as Equivalent Length of Tube - Copper tube fittings and equivalent lengths - in feets of straight tube; Darcy-Weisbach Pressure and Major Head Loss Equation - The Darcy-Weisbach equation can be used to calculate the major pressure or head loss due to friction in ducts, pipes or tubes The bending moment, M, along the length of the beam can be determined from the moment diagram.

Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length. Loading in the middle of the longest tube is a worst case for stress on a cage member. Square tube assumes bending with one side parallel to the load (think square vs diamond). The safety factors use the numbers in the table below for strength. Create two configurations; one straight and one bend. You can set up the length line equal to total lines in the bend sweep path. And then you can show both in the drawing. You can create and equation for total length and then set the straight length equal to that OR simply create direct equation and add all lengths. Mar 10, 2020 · For example, to take the bending radius into account and to calculate the length along the reinforcing bar outer surface, do the following: In Bending schedule fields, right-click in the L cell and select (formula) from the pop-up menu. Enter the following formula for the length calculation: S1 + S2 + 2*3.14*(RS + DIA)*1/4; where Sep 25, 2018 · Answer: Assuming your brand of bender uses the minimum radius of bends (most do) the NEC indicates that that figure is 4.5" for 3/4 pipe. The "length" of the bend is then 4.5", but the length of pipe used to make that bend is 3.14*4.5/2, or 7". The "loss" is then 7-4.5, or 2.5". Just multiply the degrees you’re bending by the numbers below and you will get the length of tube in the bend. So if you’re bending 90 degrees on a 6″ CLR die, your tubing in the bend is 90 *.104, which equals 9.36 inches. Now you can add the bend length to your straight tube lengths and know your actual total cut length for your tubing! The length of this line remains constant. The location of the neutral axis varies according to the material grade and thickness. The K-factor is the ratio of the neutral axis offset (t) and the material thickness (MT) KF = t/MT. The only accurate way to determine the K-factor is to bend a sample piece of steel and calculate the bend allowance. Jul 10, 2009 · Next consider the area moment of inertia of a hollow tube in bending: I = π/64*(d1^4 - d2^4) where d1 is the outer diameter and d2 is the inner diameter. Now we can find the stress. The stress on a beam in bending is: σ = M*y/I where M is the bending moment, y is the distance from the neutral axis, and I is the area moment of inertia. Note 2: The offset distance ‘’X’’ for constant flexing should never exceed 25 percent of the centre line bend radius ‘’X’’ Note 3: If the difference between ‘’L’’ and ‘’Lp” is significant, exercise care at installation to avoid stress on hose and braid at the maximum offset distance Standard draw bend radius is 2 x D What that means is that if you have a tube OD (outside diameter) of 20 mm then the bend radius to choose, if you can, is 40 mm. It is possible to have a tighter bend radius, even as low as ½ x D, although anything below 2 x D will usually require costly tooling and probably mandrel bending. The length of pipe (arc) in any bend depends on the following: (A) Number of degrees in angle of bend (B) Length of bending radius The length of arc in a pipe bend is measured along the centerline of the pipe. The radius is also measured as extending to the center-line. Use the formula below to calculate arc length. We set the pipe friction number as a constant and calculate it with the input-data. The temperature, which is used in the equation, is the average of entrance and exit of pipe. Note: You can calculate gases as liquids, if the relative change of density is low (change of density/density = 0.02). This Online Mechanical calculator is helpful in knowing the deflection of a solid round beams. The deflection of a spring beam depends on its length, its cross-sectional shape, the material, where the deflecting force is applied, and how the beam is supported. L = 0.01745 ur where L = length of bend, in., u = angle of bend, degrees, and r = radius of bend, in. The constant is a conversion from radians to degrees. Raw material length applies to straight...

If you want to find out the length of some tube before being bent then follow this equation. (2 π * R) * (X / 360) + A + B = Total Length A & B are the straight lengths either side of the bent section. X is the angle at which it's being bent. Understanding the Bend Allowance and consequently the Bend Deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. As this happens you gain a small amount of total length in your part.

So if a tube is bent to “45 degrees,” that’s 45 degrees complementary, or a 135-degree included bend angle (see Figure 2). The distance between bends (DBB) is just what it says. More specifically, it’s the distance between two tangent point s, where a straight section begins to curve and the bend starts or finishes.
