ERA Flanges Product Introduction

Function of Flanges
Flanges are critical components for connecting pipelines, valves, and equipment, primarily used for
1. Leak-proof sealing：

Ensures no leakage in high-pressure, high-temperature, or corrosive media environments.
2. Easy installation & maintenance：

Facilitates segmented pipeline assembly, inspection, and replacement.
3. System compatibility：

Adapts to pipes and equipment of different materials and pressure ratings.

Classification of Flanges
1. By Function
Electrofusion Flanges
Utilizes electric heating to fuse polyethylene (PE) pipes, achieving high-strength sealing. Ideal for gas and water supply/drainage plastic piping systems.
Features：Zero leakage risk, superior weld strength, but requires specialized equipment.

Butt-Weld Flanges (BW)
Welded directly to pipes, offering exceptional pressure resistance for high-temperature/high-pressure applications (e.g., chemical, petroleum industries).
Features：High weld joint strength, but demands professional welding expertise.

2. By Material
Steel Flanges
Forged from standard Q235B/20# steel, cost-effective and durable for general industrial pipelines.

PP Coated Flanges
Carbon steel core fully encapsulated with polypropylene (FRPP), resistant to strong acids/alkalis. More economical than stainless steel.

Stainless Steel Flanges (SS)
Made from 304/316 stainless steel, corrosion-resistant and aesthetically suited for high hygiene industries (e.g., food, pharmaceuticals).
