Unions for straight seamed ducts

New exclusive design ideal for installations of industrial extractions of solid residue carry-over (textiles, wood, paper, etc), executed with straight seamed ducts with a 7 mm folded lip.

They are manufactured in Galvanized Steel DX51 D + Z 275 MA from Ø 100 mm to Ø 1000 mm.

The joint is made with a single component that incorporates a rubber gasket M-1 inside. This ensures a high airtightness (Class C). Standard execution is carried out with screw closure M-6 / M-8. Optionally with a latch fitting closure (with 2 types of safety seals: disposable plastic or reusable in metal).

Splicing and sealing in ultrafast construction “without tools” (latch fitting closure). Easy and quick disassembly for the facilities maintenance and cleaning. Maximum reliability in the union. High finish level.

Simplicity, practicality and economy merge to give rise to a product with the best quality / price ratio in the market.

Patented product totally designed and manufactured in Spain.

We also manufacture special executions in STAINLESS STEEL AISI 304/316 or with ceramic joint M-0 for high temperatures.

Since the manufacture of the straight seamed duct allows small variations of measurement according to the used manufacturing process, we recommend them to be made according to the following sketch so that they fit perfectly to the diameters of our joining flanges.
