ABS 90 degree curved elbow is a fitting used for connecting pipeline systems, mainly made of ABS (acrylonitrile butadiene styrene copolymer), used for conveying air. The design features of this elbow enable it to provide a 90 degree turning angle to meet the layout requirements of the pipeline system. ABS material has good chemical corrosion resistance, mechanical strength, and impact resistance. When installing ABS 90 degree curved elbows, it is necessary to ensure the cleanliness and smoothness of the pipeline, avoid impurities or damage at the connection, to prevent leakage or reduce the sealing performance of the connection. In addition, the correct installation method also includes using appropriate fasteners and sealing materials to ensure the stability and safety of the pipeline system.
