What connection method is used for the white iron air duct

There are various connection methods for white iron ducts, which can be flexibly selected according to the type of pipeline, usage scenario, and construction requirements. The following are common connection methods and their applicable scenarios:

1、 Flange connection

Features: By installing flanges at both ends of the air duct and fastening them with bolts, a sealing gasket can be added in the middle to enhance air tightness.

2、 Bite connection

Features: Use professional tools to bite the edges of the air duct, forming a tight and seamless connection.

3、 Clamp type connection

Features: Mainly used for connecting steel plate circular air ducts and spiral air ducts. First, the two ends of the pipe section are rolled out with bulging ribs, and one end is reduced to a small mouth. After inserting into the large mouth according to the direction of airflow, the steel clamps are used to tighten the bulging hoops at both ends, and then fixed with bolts.

4、 Plug in connection

Features: First make the connecting pipe, then insert the air ducts on both sides, and then firmly fix them with rivets.

5、 Insert style connection

Characteristic: Insert different forms of inserts into both ends of the air duct and then compact them.

6、 Flexible hose connection

Features: Mainly used for connecting air ducts and components. During installation, the two ends of the hose are placed outside the connected pipe, and then the hose is tightened with a special soft clamp.
