Stainless Steel Welded Tube for Heat Exchanger and Boiler
Duct is a piping system used for air transport and distribution. Can be classified by section shape and material. The duct made of stainless steel duct is made of sealant (such as neutral glass glue) in the gap between the bite seam, the rivet joint and the corner of the flange. Surface dust and oil should be removed before applying sealant. According to the cross-sectional shape, the air duct can be divided into a circular duct, a rectangular duct, a flat duct, and the like, wherein the circular duct has the smallest resistance but the largest dimension and is complicated to manufacture. Therefore, the application is mainly based on rectangular ducts.
