Nov 24, 2013 · Channels have their uses, but if you really have a bending load GO WITH THE TUBE. If you send me the forces/dimensions I can run some numbers for you in an unofficial capacity. If you aren't dealing with a large amount of material, go with the tube over the channel unless money is absolutely critical. It will perform far better.
Assuming the same material, length and loading, the bending strength is limited by the Second Moment of Inertia (I) of the cross sectional area. The math is complex, and even given a calculator, it's a bit confusing. Assuming a vertical loading, You can estimate the relative change in the I value by cubing the scale change. How can I calculate the yield strength of steel tube?There's a lot of information -- and even some debates -- on which has a stronger yield strength between square and round steel tube. The majority points to square when the dimensions are equal at the same gage (1"x1" square vs. 1" diameter round).
Mar 05, 2013 · Say you had a 1/2" solid steel rod vs a 1/2" OD pipe, the solid steel rod will be much stronger in general. However, it would also be much heavier. If one used the same material, one might be able to make a 1" pipe that would be a little springier than the original solid rod, and also generally resisting bending better. Round and Square Tube Bending:Tension and Compression May 22, 2016 · The wall thickness on the inside of the tube bend will thicken due to compressive stresses. If the ultimate compressive strength of the material is reached, the tube will experience localized buckling resulting in rippling of the inside bend surface. In tube bending you can bend round or square tubing.
ASTM A500 is the common steel specification used for hollow structural tubes. This specification forms welded carbon steel tubing in round, square and rectangular shapes. This square tubing deflection calculator calculates tube deflection for square based on length of beam, tube size, decimal gauge and load. Steel Pipe Bend Specifications (Differences with Elbow As we talked above, Steel pipe bend radius:Above 2 times of D, so there are 2D, 2.5D, 3D, 5D, 6D, 7D or 8D pipe bend. Steel pipe elbow radius:R=1D or R=1.5D or 2D. Below 1.5D is short radius elbow, and more than 1.5D but not over 2D is long radius elbow. R is radius of curvature; D is (elbow or bend) pipe diameter.
Steel pipe bend is a bending pipe that used to change the pipeline direction. It is similar to pipe elbow, but differently pipe bend is longer than elbow and usually manufactured for the specific needs. So depends on different bending radius (R) to distinguish bend and elbow. Strength of Steel Vs. Wood HunkerSteel is more brittle than wood, making it a poor choice for structures that will be bearing high loads for a long time. Wood and steel have the same "stiffness" strength -- that is, how far they will bend before showing signs of wear; but wood is better for structures where the stress is constant and regular, such as in a house.
I'm pretty confident that 2" square tube will resist bending better than 2" round tube of the same wall thickness but when it comes to twisting, I wonder if there is any difference. I think the round shape would resist twisting better than a square shape, but the 2" square tube would have more stock around the circumference than the 2" round. Structural Steel Design Flexural MembersSteel flexural members Beams in building frames Elements carrying lateral loads Equipment, etc. Useful in pure bending as well as in beam-columns Design Clauses:CAN/CSA-S16 Bending strength as per Clauses 13.5, 6 & 7 Shear strength as per Clause 13.4 Local buckling check:Clause 11 (Table 2) Special provisions:Clause 14
Other bending variables include the inside bend radius (sometimes called the intrados); the outside bend radius (or extrados); and the centerline radius or the neutral line, where neither compression nor stretching occurs.The bend angle refers to the complementary angle of bend. So if a tube is bent to 45 degrees, thats 45 degrees complementary, or a 135-degree included bend Tube and pipe basics:How to achieve the perfect bendOther bending variables include the inside bend radius (sometimes called the intrados); the outside bend radius (or extrados); and the centerline radius or the neutral line, where neither compression nor stretching occurs.The bend angle refers to the complementary angle of bend. So if a tube is bent to 45 degrees, thats 45 degrees complementary, or a 135-degree included bend
Yield strength on schedule 80 pipes runs a wide gamut depending upon the manufacturer and type of galvanized steel used. For instance, schedule 80 pipes produced by Wheatland Tubes exhibit a minimum yield strength of 30,000 PSI or 205 MPa, while One Steel produces schedule 80 pipes with a minimum yield strength of 250 MPa, or about 36,260 PSI.Tube Calculator - Rogue FabricationThis is one of the strongest aluminum alloys, and is not very weldable and is very difficult to bend. ASTM A53 Pipe:See our discussion on the bender tech page-Tube vs Pipe. This medium/low strength steel is manufactured to the requirements set by the American Society for Testing and Materials (ASTM), document A53.
