HDPE Buttfusion Fittings - 45 Degree Elbow

Product Features

✅ High strength and pressure resistance: Using PE80/PE100 grade raw materials, it has strong pressure bearing capacity and is suitable for pipeline systems of different pressure levels.

✅ Excellent corrosion resistance: It can resist the erosion of acids, alkalis, salts and various chemical media, and is suitable for chemical and sewage treatment environments.

✅ Flexible and earthquake-resistant: HDPE material has good flexibility, can adapt to foundation settlement and earthquake effects, and reduce the risk of pipeline rupture.

✅ Low flow resistance design: Smooth inner wall reduces fluid resistance and improves delivery efficiency.

✅ Reliable hot-melt connection: Electric fusion or hot-melt butt connection is adopted to ensure seamless and leak-free interfaces.

✅ Lightweight and easy to install: The weight is only 1/8 of that of a metal elbow, making construction easy and reducing labor costs.

✅ Long life: Anti-aging, anti-ultraviolet (some models contain anti-UV additives), the service life can reach more than 50 years.

Key Features of 45° Elbows

Smooth Angle Change

Providing a 45° change of direction is its most fundamental characteristic. Compared to a 90° right-angle turn, the 45° elbow's turning is much smoother and more gradual.

Superior Hydraulic Performance

This is one of the most prominent features of the 45° elbow. Due to its smaller angle, the change in fluid direction is gentler, resulting in significantly less local head loss than a 90° elbow. This advantage is particularly crucial in long-distance or high-flow-rate transport systems where pressure drop and pumping energy consumption need to be minimized.

Flexible Combination and Layout Adaptability

Two 45° elbows can be combined to form various angles (such as 90°, zigzag offsets), providing more flexible and precise pipe positioning and detour capabilities than a single 90° elbow. This combination is often used to achieve parallel pipe offset to avoid underground obstacles.

Excellent stress distribution and absorption capacity

The gentler angle allows it to more effectively disperse and absorb stress when dealing with axial or lateral displacement of pipelines caused by thermal expansion and contraction, foundation settlement, etc., sometimes providing better protection for the pipeline system than a 90° elbow.

Reliable connection method

Butt fusion ensures the strength and sealing of the connection interface, achieving an integrated, leak-free system.
