What Is Hypodermic Tube Bending


When parts essential to the medical, automotive and aeronautical or military industries are created from scratch, some very specific measurements and specifications have to be taken into consideration during its creation. When the material used to create the part calls for hypodermic tube to be used, all specifications provided by the designer become critical indeed. When any tubular part is designed, whether it is stainless tubing or aluminum tubing, there are three very important essentials to consider when it comes fabricating that part: the size, the material, the temper and the method used to draw or bend the tube.

For most medical applications, stainless steel is the material of choice, because of its durability and the ease of sterilization. When stainless steel is included in the specifications, it is the fabrication material known as hypodermic tube. Sometimes referred to as needle tubing, it is identified through its gage size or the outside diameter, OD and the inside diameter or ID. The temper is always considered "hard" for this type, referring to material strength.

Hypodermic tube is often used for small diameter tube bending, the smallest gauge of which would be 35 ranging to 6 gauge. When it comes to measuring gauge- the higher the number, the smaller the actual measurement. Some medical and aerospace applications will require having very small tubes bent and fabricated to match some very odd angles, so that certain pressure ranges can be achieved at all times. Often stainless steel material will become interchangeable with glass, because some materials can be bent easier than others, especially when dealing with finite and negligible angles.

Care must be taken, especially with hypodermic tubing, to preserve the OD/ID measurements during processing. One flaw or ripple, and the entire fabricated piece can be ruined and unable to be used for the function it was intended for.

The most commoon medical applications for bent hypodermic tubing is specialty hypodermic needles, catheters, IV units, and a host of fluid moving devices. It also plays an important role in surgeries. For aeronautics and military, the same applications as the automobile, only upgraded to include aircraft and naval applications. If it can be used to move fluid or exert pressure, small diameter tubing will be doing the job.
