Straight Duct
After processing through shearing or rolling into a round shape, automated welding arms are used for direct welding to form the shape. After forming, flanging and flange installation allow for connection between pipe fittings. Finally, galvanized straight pipes are typically coated to provide corrosion and acid resistance on the surface, allowing for the passage of toxic gases.
Tee Pipe (Tee Fitting)
Using straight pipes to create connections in three directions, for use in corner or directional changes. After laser processing, the rolled pipe is manually welded by the craftsman, then inserted into the flange and flanged. Typically, a coating process is applied to allow for corrosion resistance and acid resistance on the surface, enabling the passage of toxic gases.
Lobster Joint Bent Pipe
Used in conjunction with straight pipes, most commonly available in 90-degree and 45-degree angles, or customized angles, with selectable joints. Through laser cutting, rolling, and manual welding by craftsmen, followed by insertion into flanges and flanging, the connected pipe fittings are typically subjected to a coating process (Coating) to provide surface corrosion and acid resistance, allowing for the passage of toxic gases.
