45-Degree Elbow
PRODUCT PARAMETERS
45° elbow is a core pipe fitting for gentle directional change in piping systems. It is available in two specifications: Long Radius (LR) and Short Radius (SR), with a bending angle of 45°. Featuring a smooth structure, it reduces fluid friction and pressure loss, ensuring stable medium transportation. It is suitable for various industrial working conditions such as high temperature, high pressure and corrosive media, and supports customized processing.
Application Fields:Widely used in petroleum, chemical industry, oil and gas transportation, electric power energy, metallurgy, shipbuilding, pharmaceutical, heating, long-distance pipelines and other industries. It is applicable to harsh working conditions involving steam, oil products, gas, flammable, explosive and corrosive media, and is especially suitable for engineering scenarios requiring gentle directional change of pipelines.
