A Buttweld 90 Degree Short Radius Elbow is a type of pipe fitting used in plumbing and piping systems. It is designed to change the direction of flow in a pipe by 90 degrees and has a shorter radius than the standard 90 siku darjah.
The short radius elbow is used in situations where there is limited space and the turn radius needs to be smaller. They are commonly used in tight spaces in industrial, commercial, and residential piping systems.
This type of elbow is made by welding two pipe sections together at a 90-degree angle, and has a smooth inner surface to allow for maximum flow of liquids or gases. It is typically made of materials such as carbon steel, keluli tahan karat, or alloy steel.
buttweld 90 Degree Short Radius Elbows are available in various sizes and can be customized to meet specific requirements. They are known for their durability and strength, making them a popular choice for industrial applications where high-pressure or high-temperature conditions are present.
