Description
Product Description Elbow DIN 2605
DIN 2605 is a German standard for pipe fittings, specifically for elbows, used to connect pipes at various angles. It specifies different types of elbows based on their design and application.
Here’s a breakdown of the three types of elbows:
- DIN2605 Elbow Type 1 – Short Radius Elbow (SR):
- This type has a smaller radius and is used in situations where space is limited. The center-to-face dimension of a short radius elbow is approximately equal to the nominal pipe diameter.
- Commonly used in applications where the space for piping is constrained.
- DIN2605 Elbow Type 2 – Long Radius Elbow (LR):
- This elbow type has a larger radius, usually 1.5 times the nominal pipe diameter. It provides smoother flow and less turbulence, making it suitable for high-pressure systems or when reduced friction loss is important.
- It’s the most commonly used elbow type in industrial piping systems.
- DIN2605 Elbow Type 3 – Reducing Elbow:
- This type is used when there is a need to connect pipes of different diameters. It allows a smooth transition between pipes with varying sizes, ensuring that the flow remains stable.
- Often used in systems where the pipe size is being reduced or enlarged at specific points.

Material
- Carbon Steel (CS): Often used for general-purpose applications. Common grades include:
- P235GH
- P265GH
- S235JR
These grades offer good weldability and strength, making them suitable for many industrial applications, such as steam, water, and gas transport.
