What is the back ring?
The basic ring is a small piece of material welded between two pipes. They are usually round to fit most of the pipes, but there are also square -shaped rings. It is also called a backup ring or an anti-extrusion ring. A typical backrest is made of rubber or metal such as aluminum, chrome or carbon steel. The pipe rings allow proper alignment between two connected pipes, hold the joints together and prevent leaks. Other advanced pads include Grove, Flat and Ridge. The exact choice of the pad depends on the application for which it is intended for use. They are used to hold pipes and fittings together in industries such as the automotive industry, construction and aviation. It is then welded so that the material is melted and melted with the tubes. If used correctly, it prevents the spin from penetrating through the tube. This transforms two tubes and the rear ring into one tube.
The quality, type and skill of the welder are essential factors for efficient backing of the rings. The aim is to create a smooth and smooth appearance of pipes. Even more importantly, no cracks or slots should be left to ensure the integrity of the pipeline. No welded materials can be allowed and connected to the interior of the pipe to ensure a smooth flow of water, gas or other chemicals.
The basic ring is a good welding piece, because the joint it creates is relatively stronger than those created by direct soldering. Support for the support ring of the pipeline supports and aligns both pipes to facilitate welding and adapt to the worker. It has the disadvantage of leaving very small cracks and slots they have not seen with the naked eye. After some time, the slits will catch bacteria and ions such as chloride that causes corrosion. The threads that are not installed correctly break due to thermal and mechanical voltages.
When using a pad, more hits are neededin the workforce for correct assembly. Its relative complexity of use compared to simple welding requires advanced welding skills. High cost of accompanying rings can be discouraged by construction companies from their normal use in their projects.
