Bending stainless steel pipe with heat.

Rigid metal pipe and tubing tend to be made of copper steel stainless steel or aluminum but are not the same thing. If you do not have access to a press brake your other option is to use an oxy acetylene torch to heat the rod.

Welding of stainless steel.

The specifications called for as few welded joints and flanges as possible. 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. Play the flame back and forth along the line keeping. Carbon steel case hardened you may burn the surface carbon out.

Most grades of stainless steel can be welded by all traditional welding methods. Clamp the stock in a vise. Generally tube is measured by the outside diameter while pipe is measured by the inside diameter so pipe may appear thicker than tubing of the same measurement. Rotary bending and hydraulic press bending can both be employed to bend stainless steel tube.

The pipe was 3 4 and 2 schedule 40 316l stainless steel. This makes bending stainless steel with common hand tools difficult and a sheet metal brake is often required although one technique to bend stainless steel using hand tools works well on shorter length bends. When you bend a stainless steel rod mechanically with a press brake you create a bend that has a true radius. You can make simple bends in iron and steel using nothing more than a torch to heat and soften the metal.

Centre line bend radii should not be smaller than twice the tube diameter. For example piece of one inch pipe will seem to have a greater diameter than a piece of one itch tubing. This method tends to damage the tubing however. Another method of bending stainless steel tubing is to use a mandrel bending machine which is a flexible insert that fits into your tubing bending it without allowing it to collapse internally.

However the weldability of different grades can vary considerably. 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. I cold bent nearly every piece of this job with a greenlee electric conduit bender. Heating the metal with a soapstone pencil mark a line across the stock to indicate the center of the bend.

As you bend a stainless steel sheet the bend area cold hardens increasing the amount of pressure required to finish the bend. To bend steel tubing use a tube bender which you can pick up at your local hardware store. Galvanized iron you will burn off the outside zinc coating. I show you how you bending pipe without kinking.

There are two ways to bend stainless steel rod one requires force and the other requires heat.
