According to the angle of the aluminium elbow, there are aluminum 45 degree elbow, aluminum 60 degree elbow, aluminum 90 degree elbow, aluminum 180 degree elbow, etc, the other angle can be according to customer requirements for custom processing, and also can be divided into different shapes and uses: Grooved aluminum elbow, Jacketed aluminum elbow，Double bearing aluminum elbow，Flanged aluminium elbow，Stamping aluminium elbow，Faucet aluminium elbow, Street aluminium elbow etc.

Aluminum alloy elbows common alloy number has 1060,5052,5083,6061,6062 and so on, 6061 aluminium elbow is a high quality aluminum alloy product produced by heat treatment and pre stretching process, its magnesium and silicon alloy content is much, and its processability is excellent. It has excellent weldability and electroplating performance, at the same time, it has high toughness, good corrosion resistance,no deformation after processing, dense material, easy polishing, no defects, excellent oxidation effect and other excellent features.
Matters needing attention in actual installation of aluminum elbows: before the installation of aluminum elbows, it must be verified whether its passage meets the standard requirements of Engineering elbow interface, clean surface dirt. Aluminium elbow general conditions can be installed in any position of the pipeline, but in order to facilitate operation and maintenance, we should pay attention to the aluminium elbow medium flow should be vertical valve below the upstream, so the aluminum elbows can only be installed horizontally. Aluminum elbows should pay attention to sealing in installation, prevent leakage phenomenon, affect the normal operation of the pipeline. Aluminium elbow ball valve, globe valve, gate valve use, only for full open or full closed, not allowed to do adjustment flow, so as to avoid the sealing cover erosion, accelerate wear.
Our standard for making aluminum elbows: The appearance of aluminum elbow should be beautiful and conform to the quality standard of appearance, the surface should be free of cracks and sand defects,and do not allow more than the wall thickness of the existence of dent.If there are small cracks, should all wear off, the grinding depth shall not exceed the standard size, between the grinding and non processing surface feels smooth transition.

The aluminium alloy elbow needs the correct maintenance and the maintenance, due to the soft texture of aluminum material, so in use, according to the use of the environment, regular cleaning. In case of erosion and pollution, the soft cloth can be dipped in alcohol, washed with clean water, and can not be washed with acid or alkaline detergent, and should be cleaned by warm water with lubricant or neutral detergent.
