Introduction
Plumbing and piping systems rely on small but essential fittings. One of the most widely used is the 20 mm galvanized elbow. This fitting plays a vital role in changing pipe direction, preventing leaks, and ensuring system durability.
Galvanized elbows are made from steel pipes coated with zinc. The galvanization process provides extra protection against rust, making the fitting highly durable. A 20 mm galvanized elbow is ideal for water supply lines, irrigation systems, and industrial piping.
Fortis Forge, a leading forging and manufacturing company, produces high-quality galvanized fittings. Their precision-engineered elbows meet industry standards, offering reliability for both domestic and commercial projects.
What is a 20 mm galvanized elbow?
A galvanized elbow is a pipe fitting that changes the flow direction of water, gas, or air. The 20mm size refers to its internal diameter, which fits standard 20mm pipes.
Its main features include
Zinc coating for corrosion resistance.
Durability under pressure and temperature variations.
Compatibility with threaded or welded connections.
These fittings are commonly available in 90-degree and 45-degree bends. The angle depends on the piping layout and application.
Importance of Using Galvanised Elbows
Corrosion Protection – Zinc coating prevents rust and extends lifespan.
Leak Prevention—Proper sealing ensures reliable performance.
Strength – Withstands high water pressure and external stress.
Versatility—Suitable for residential, agricultural, and industrial systems.
Cost Efficiency – Low maintenance and long life reduce expenses.
Fortis Forge manufactures galvanised elbows with a strong focus on durability, making them a preferred choice for contractors and builders
Types of 20mm Galvanised Elbows
Galvanized elbows come in several variations. Each type serves specific needs.
1. 90-Degree Elbow
Most common type.
Changes pipe direction by 90 degrees.
Used in corner installations.
2. 45-Degree Elbow
Creates a smoother directional change.
Reduces friction compared to 90-degree bends.
Ideal for irrigation pipelines.
3. Street Elbow
One end is male-threaded and the other female-threaded.
Saves space in compact installations.
4. Long Radius Elbow
Provides gradual directional changes.
Reduces pressure loss in the system.
5. Short Radius Elbow
Used where space is limited.
Creates sharp directional turns.
Materials and Manufacturing
The 20 mm galvanized elbow is manufactured from steel or iron pipes. The galvanization process coats the fitting with zinc to prevent rusting.
Steps include:
Forging the raw steel into elbow shapes.
Cleaning the surface to remove impurities.
Dipping the elbow in molten zinc.
Cooling and finishing for uniform coating.
Fortis Forge uses advanced forging techniques to ensure the elbows meet global safety and performance standards.
Applications of 20mm Galvanised Elbows
Residential Plumbing – Used in water pipelines for homes.
Agriculture—Ideal for irrigation systems and farm pipelines.
Industrial Piping—Ensures durability in chemical and manufacturing plants.
Water Supply Systems – Distributes clean water in urban and rural networks.
Construction Projects – Widely used in commercial buildings.
Standards and Certifications
20 mm galvanized elbows must comply with national and international standards:
IS Standards (India): Ensures product safety for domestic use.
ASTM Standards (USA): Defines material and coating specifications.
EN Standards (Europe): Covers pressure and corrosion resistance.
BS Standards (UK): Focuses on pipe fitting quality.
ISO Certification: Ensures global quality compliance.
Fortis Forge ensures that all elbows are tested and certified before reaching customers.
Benefits of 20mm Galvanised Elbows
Long-lasting performance due to zinc coating.
Affordable and widely available.

Challenges and Maintenance
Even though galvanized elbows are durable, they may face challenges such as
Zinc coatings wear over time.
Risk of scaling inside the pipe.
Limited use for hot water due to coating damage.
Maintenance tips:
Inspect joints regularly.
Apply sealing compounds to threads.
Replace damaged elbows quickly.
