Customised Mild Steel Tubes,Pipe Bends  

The piece is connected with a duct by inserting one into the other. The pressed form of the ventilation piece helps to reduce the flow resistance and the pressure loss. Air tightness can be increased to class B by wrapping the joints with the TAL, MET or DUCT sealing tape. Air duct elbow from the production process is divided into: spiral seam forming, welding forming, a total plate forming; Elbow Angle: 45°, 60°, 90° or customized duct elbow. High quality stainless steel, galvanized sheet, features: corrosion and rust, good sealing. Can be customized according to customer requirements of all kinds of Circular Duct Series and Rectangular Ducts Series products. Pressed bends are designed for building ventilation systems based on spiral and plain ducts. Seam welds improve the air tightness of the ventilation system, while the hemmed rim helps to avoid cutting injuries during handling and installation.
