Product Overview
HDPE 90 degree elbow is a pipe connector made of high-density polyethylene (HDPE) material, which is specially used to change the direction of the pipe (90-degree turn). Through hot-melt butt welding technology, seamless connection with HDPE pipes can be achieved to ensure system sealing and long-term stability. It is widely used in water supply and drainage, chemical industry, agricultural irrigation, gas transportation and other fields.
Advantages of HDPE 90 degree elbow
1. Excellent corrosion resistance
Acid and alkali resistant, chemical resistant, suitable for conveying various liquids and weakly corrosive media, with a service life of more than 50 years.
2. High strength and impact resistance
HDPE material is highly flexible and can withstand ground subsidence and external pressure, and still maintains excellent impact resistance in low temperature environment.
3. Zero leakage seal
The butt welding process integrates the elbow and the pipe, completely eliminates the risk of interface leakage, and ensures system safety.
4. Lightweight and easy to construct
The weight is only 1/8 of the metal elbow, which is convenient to carry and install, greatly reducing labor costs.
