cold bend steel pipe Introduction

field cold bending - Pipelines, Piping and Fluid Mechanics ...

Nov 17, 2009 · General rule of thumb for field cold bending (onshore pipelines) is 40D bend raius. Does anyone know the origin of this? Further, for large diameter pipes this gives fairly sensible bends achievable for a double random pipe length (12m).

The rule of thumb they refer to in CSA Z662-07 for 12"-D pipe is 1.5 degrees change in direction per pipe diameter of arc length. I prefer to evaluate things in terms of outer fibre elongation; the ASME B31.3 Code for impact-tested material would limt outer fibre elongation to 5%. Since most line pipe in industry (here anyway) has some impact test qualification to Category III or Category II, you could probably "get away with" 5% elongation, but without field hardness testing I wouldn't want to go there. I read somewhere in a myriad of articles about a year ago that common practice in the USA P/L industry is to limit outer fibre elongation to 2% - 3%, thereby permitting cold field bends in the (approximately) 25-D radius range. Regards, SNORGY.You might want to look at the document ES-24 published by the Pipe Fabrication Institute as it provide some guidance on acceptable cold bend radius based on the method in use (type of machine). General rules of thumb that I've used for cold bends are as follows 10" and smaller with a polyethylene coating, no less than 30D (2 degress per diameter of length) to prevent damage to coating. 12" and larger with polyethylene coatings, no less than 40D (1.5 degrees per diameter of length). All all pipe with fusion bonded epoxy coatings, no less than 40D (1.5 degrees per diameter of length). For uncoated pipe, I default to the Design Code in use (B31.3, B31.4/8, or Z662). Note Look at Clause 841.23 of B31.8 as I think it has quite a bit of guidance. Note also that anything with fiber elongation more than 5% (a 10D bend) in sour service requires stress relieving or heat treatment per NACE MR0175/ISO 15156.1In the pipeline codes B31.4 & B31.8 you will find the minimum permitted bend radaii in, B31.4 PP 406.2 B31.8 PP 841.231 B31.4 is quoted as follows, and BOTH CODES HAVE THE SAME IDENTICAL TABLE [quote] (b) Except as permitted under para. 406.2.l(c), the minimum radius of field cold bends shall be as follows Minimum Radius of Nominal Pipe Size Bend in pipe Diameters NPS 12 and smaller 18D 14 21 16 24 18 27 NPS 20 and larger 30 ********************** "Pumping accounts for 20% of the world's energy used by electric motors and 25-50% of the total electrical energy usage in certain industrial facilities."-DOE statistic (Note Make that 99% for pipeline companies) http://virtualpipeline.spaces.live/1pipeliner3000 Depending on the pipe, you can generally get a little more than 10 degrees though. For example, currently working with some 24", X-65, 1.000" WT API 5L pipe and we are getting up to 12 degrees per joint with the cold bend trials. Greg Lamberson, BS, MBA Consultant - Upstream Energy Website oil-gas-consultingThanks, all suggests that 40D bend is not the minimum for 6" pipe. However, 40D gives 8.5 degrees per metre (85 degrees in 1 joint)that I don't believe can practically be pulled in on a standard field cold bending machine. Any ideas what might be acheivable??Buy a 5D90 and field cut it. ********************** "Pumping accounts for 20% of the world's energy used by electric motors and 25-50% of the total electrical energy usage in certain industrial facilities."-DOE statistic (Note Make that 99% for pipeline companies) http://virtualpipeline.spaces.live/You could call your contractor and ask him what he can do with his machine?Pipe Bend - Pipelines, Piping and Fluid Mechanics ...Apr 27, 2010Cold bending of straight pipe See more results

3 Ways to Bend Steel Tubing - wikiHow

Mar 28, 2019 · To bend steel tubing, use a tube bender, which you can pick up at your local hardware store. Make sure you get a tube bender and not a pipe bender since a pipe bender won't fit steel tubing and it may cause buckling or kinks. You can also bend steel tubing by securing it in a vice and heating it up with a blow torch until you're able to bend it.
