Pipe bends for industrial extraction systems

Industrial extraction pipe bends in stainless steel, painted steel and galvanised steel
Pipe bends change the direction of airflow in industrial extraction systems. Their diameter, bend radius and design influence the pressure loss and must be considered when planning the ductwork.
At WELAfix, you can find pipe bends in stainless steel, painted steel and galvanised steel. Depending on the product series, they are available as segmented or pressed bends in different angles and diameters. Choose a bend that matches your extraction pipes and connection system.
What do pipe bends do in an extraction system?
Pipe bends route air, dust and chips around machines, walls and other obstacles. Every change of direction creates some flow resistance. The bend radius and the number of bends therefore matter when designing an extraction system.
When choosing a pipe bend, check:
- the outside diameter and wall thickness;
- the bend angle and radius;
- the connection type and compatibility with adjacent components;
- the extracted material and expected wear.
For abrasive materials, pay particular attention to the wall thickness and the suitability of the chosen bend for the operating conditions.
Which pipe bend material suits your application?
WELAfix offers stainless steel, galvanised steel and painted steel pipe bends. The right material depends on the extracted material, moisture exposure, ambient conditions and required corrosion resistance.
- Stainless steel pipe bends: an option where increased corrosion resistance is required. Check the specific steel grade for the substances involved.
- Galvanised steel pipe bends: zinc coated for corrosion protection in suitable conditions. Check the coating and exposure conditions before using them outdoors.
- Painted steel pipe bends: a robust option for many extraction systems handling non-aggressive materials. The protective effect depends on the coating and its condition.
Stainless steel pipe bends
Stainless steel can be suitable for applications involving moisture or corrosive substances, provided that the selected steel grade is compatible with the medium. WELAfix offers, among other products, SSBE segmented bends with beaded edges and SSBJ pressed bends. Check the available sizes, angles and connection details for the individual product.
Galvanised pipe bends
The zinc coating helps protect steel bends against corrosion. For outdoor installations or areas with high humidity, the suitability of the coating depends on the actual exposure conditions. The WELAfix range includes galvanised segmented bends with beaded edges for connection to compatible duct components.
Painted steel pipe bends
Painted steel bends are used in extraction systems for applications such as wood and metal processing. They can convey chips and other suitable, non-aggressive materials. WELAfix offers different segmented and pressed versions. Check the coating, wall thickness and connection type for your application.
Where are extraction pipe bends used?
Pipe bends are used wherever an extraction or ventilation duct must change direction, for example:
- chip extraction in woodworking and metalworking;
- dust extraction at machines and production lines;
- industrial process air and ventilation ductwork;
- intake and discharge ducts, including suitable outdoor installations.
For each application, match the outside diameter, wall thickness, bend radius and connection type to the rest of the system. If the conveyed material is abrasive or corrosive, check whether the selected product is suitable for those conditions.

Pipe bends: frequently asked questions
Which types of pipe bend are available?
WELAfix offers pipe bends in stainless steel, painted steel and galvanised steel. Depending on the series, you can choose segmented or pressed bends in various angles and diameters. Check the product details for the available combinations.
Which dimensions do I need to check?
Check the outside diameter, wall thickness, bend angle, bend radius and connection type. The available dimensions vary by material and design.
Which material should I choose?
The choice depends on the extracted material and operating environment. Painted steel is an option for many non-aggressive applications. Galvanised steel provides corrosion protection in suitable conditions. Stainless steel may be appropriate when greater corrosion resistance is required, subject to the steel grade.
What is the difference between a pressed bend and a segmented bend?
A pressed bend is formed into its curved shape. A segmented bend is assembled from several sections. Their available dimensions, wall thicknesses and connection types differ by product series; check the technical data before ordering.
