Product Description

Segmented (welded) reducers made of black steel (2 mm) — are elements for connecting flue pipes of different diameters. They are used when the difference in diameters is significant—exceeding 30 mm (or three standard sizes).

Segmented reducers are divided into two types (S1 and S2) depending on the connection type:

• Type S1: The larger diameter has a "female" socket (external, +), and the smaller diameter has a "male" spigot (internal, -). Example: 200(+)/160(-).
• Type S2: The larger diameter has a "male" spigot (internal, -), and the smaller diameter has a "female" socket (external, +). Example: 200(-)/160(+).

Segmented reducers are generally made to order. In addition to the standardized sizes listed in the table, custom-sized reducers can also be ordered.

Key Features

• Reliable Connection: The design (S1 or S2) allows for a secure connection of chimney system elements with a large diameter difference.
• Durability and Heat Resistance: A 2 mm wall thickness and TIG-welded seams provide resistance to high temperatures (Class T600) and burnout. The element is rated Class G (soot fire resistant).
• Condensate-Proof Design: Correctly choosing the type (S1 or S2) ensures proper installation direction to prevent condensate leakage.
• European Certification: The product complies with the European standard EN 1856-2 and is CE marked, confirming its high quality and safety.

Available Sizes and Specifications

The tables below show the range of standardized S1 and S2 segmented reducers.

S1 Reducer Range (larger Ø "female" (+), smaller Ø "male" (-)

S2 Reducer Range (larger Ø "male" (-), smaller Ø "female" (+)

Important Limitations

• Application: Intended for use with wood-burning stoves, fireplaces, and solid fuel boilers.
• Diameter Check: Before purchasing, ensure the reducer diameters match the pipes being connected.
