Easier assembly guarantees fast, problem-free, and thus also more economical on-site preparation.
Stiffening of air ducts and equipment
Available:
- Pipes
- Clamps
- Rawlplugs
- Screws
- Plates
- Material: galvanized high-quality stainless steel
Flanged joints with the normal static air pressure cannot indicate any deflexion of more than 1/250 of its longest side when subjected to maximum nominal pressure as per duct classification.
In addition, under normal static air pressure none of the walls of the steered duct can have bulges and/or dents larger than 3% of its width or more than 30 mm, depending on which value is lower.
It is for this reason that ducts compliant to DIN EN 1507 are part of tenders and failure to abide by regulations regarding stiffening can cause serious consequences for the entire duct system.
