Introduction
When it comes to building robust and long-lasting piping systems, the choice of fittings is just as important as the choice of pipes. Among the many fittings available, the 20mm galvanised elbow stands out as one of the most essential components. Whether you are working on plumbing for residential buildings, industrial pipelines, or irrigation systems, elbows are crucial for changing the direction of flow without compromising the strength or efficiency of the line.
At Fortis Forge, we specialize in manufacturing and supplying high-quality galvanised fittings, including the 20mm galvanised elbow, to meet the growing demands of construction, industrial, and infrastructure projects.
In this blog, we’ll cover everything you need to know about 20mm galvanised elbows—their meaning, applications, advantages, specifications, and why Fortis Forge is the leading supplier for your piping needs.
What is a 20mm Galvanised Elbow?
A 20mm galvanised elbow is a pipe fitting that connects two pipes at an angle—most commonly 90° or 45°—allowing a change in the direction of flow. The “20mm” refers to the nominal bore size, meaning it is designed to connect pipes with a 20mm diameter.
The term galvanised refers to the protective zinc coating applied to the fitting. This coating prevents rust, corrosion, and other environmental damage, significantly increasing the lifespan of the fitting.
Key Features of a 20mm Galvanised Elbow:
Size: 20mm nominal bore.
Material: Carbon steel, mild steel, or malleable iron coated with zinc.
Angles Available: 45°, 90°, and custom degrees.
Finish: Hot-dip galvanised for superior corrosion resistance.
Durability: Long-lasting, even in harsh conditions.
Applications of 20mm Galvanised Elbow
The 20mm galvanised elbow is widely used in multiple industries. Here are the most common applications:
1. Residential Plumbing Systems
Galvanised elbows are commonly used in water supply lines, drainage systems, and gas lines in households. They provide leak-free connections and ensure a long service life.
2. Agriculture and Irrigation
In farms and irrigation systems, galvanised elbows play a vital role in controlling water flow through sprinklers and pipelines. The rust-resistant coating ensures durability even with constant exposure to water.
3. Industrial Pipelines
Industries dealing with water, steam, or compressed air rely on 20mm galvanised elbows for smooth directional flow. They are also used in manufacturing plants where chemical resistance and mechanical strength are crucial.
4. Gas Distribution Lines
Because of their high-pressure resistance and safety, galvanised elbows are ideal for gas distribution systems, ensuring leak-proof and secure connections.
5. Fire Protection Systems
Sprinkler and fire hydrant systems often use galvanised elbows due to their ability to withstand pressure and corrosion, ensuring safety in emergency situations.
6. Construction Projects
From high-rise buildings to road infrastructure, galvanised elbows are widely used in structural piping, scaffolding, and drainage systems.
Advantages of 20mm Galvanised Elbow
Using a 20mm galvanised elbow comes with several advantages:
1. Corrosion Resistance
The zinc coating protects the fitting from rust and oxidation, extending its life even in humid or wet environments.
2. Durability
These elbows are strong enough to handle pressure, temperature variations, and mechanical stress, making them suitable for both domestic and industrial use.
3. Cost-Effective
Galvanised elbows offer a long service life, reducing replacement and maintenance costs.
4. Easy Installation
The fittings are designed to provide seamless connections, making them easy to install and replace.
5. Versatility
The 20mm size is one of the most commonly used dimensions, compatible with multiple piping systems and applications.
6. Environmentally Friendly
Galvanised steel is recyclable, making these fittings an eco-friendly choice.
Types of Galvanised Elbows
At Fortis Forge, we provide a wide variety of 20mm galvanised elbows to suit different requirements:
1. 90-Degree Galvanised Elbow
The most common type, used to make right-angle turns in piping systems.
2. 45-Degree Galvanised Elbow
Used when a smaller directional change is needed.
3. Long Radius Elbow
Provides smoother flow with less friction, often used in high-pressure systems.
4. Short Radius Elbow
Ideal for compact areas where space is limited.
5. Threaded Elbow
Has internal threads for easy connection with threaded pipes.
6. Socket Weld Elbow
Used where high-pressure strength and leak-proof joints are required.
