HDPE 90˚Elbow is used for 90 degree bends that change the direction of pipes. It allows pipes to achieve smooth turns where they need to be to adapt to pipe layouts or around obstacles.
HDPE 90˚Elbow may be more competitive than metal Elbows (such as cast iron, copper, stainless steel, etc.) because the cost of HDPE materials is lower and the manufacturing process is simpler and more convenient.
Its lifespan depends on many factors, including usage environment, operating conditions, installation quality, etc. Generally speaking, HDPE materials have a long lifespan, which can reach more than 50 years.
