Support rings, also known as backup or anti-extrusion rings, are small pieces of material welded between two pipes to align and hold them together. They come in various types and materials, including rubber and metal, and are used in industries such as automotive, construction, and aerospace. The quality of the welder is crucial for their effectiveness, and they can create stronger joints than direct welding. However, they may leave small cracks that can trap bacteria and ions, causing corrosion over time.
A support ring is a small piece of material welded between two pipes. They are usually round to fit most tubes, but there are also rings that are square in shape. It is also called backup ring or anti-extrusion ring. A typical backup ring is made of rubber or metal such as aluminum, chrome, or carbon steel. Pipe support rings allow for proper alignment between two joined pipes, hold pipe joints together and prevent leaks.
There are many types of backup rings, including plain rings, machine welded rings, and gasket rings. Others, more advanced, include the grove, flat and ridge types. The exact choice of ring depends on the application for which it is intended. They are used to hold pipes and fittings together in industries such as automotive, construction and aerospace.
The support ring is placed between the ends of two pipes to secure a joint. It is then welded so that the material is melted and fused with the pipes. When used correctly, it prevents solder from seeping through pipes. This turns the two tubes and the ring into one tube.
The quality, type and skill of the welder are crucial factors in the effectiveness of backup rings. The goal is to create a smooth, uniform look for the pipes. Most importantly, no cracks or crevices should be left to ensure the integrity of the pipe. No welded material can splash and stick inside the pipe to ensure the smooth flow of water, gas or other chemicals.
A backup ring is a good weld piece because the joint it creates is relatively stronger than that created by direct welding. A pipe joint support ring supports and aligns the two pipes to facilitate welding and correct assembly by the operator. It has the disadvantage of leaving very small cracks and fissures that are not visible to the naked eye. Over time, these crevices will trap bacteria and ions, such as chloride, which will cause corrosion. Rings that are not installed correctly will break due to thermal and mechanical stress.
