Spiral Duct

Where most other types of ducting are formed from sheet metal, spiral duct pipe is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lock seam. It has a relatively smooth interior for low friction loss with the grooved seam entirely on the outside. Typically, spiral duct is available in any length and although longer lengths of pipe do reduce the number of connections that need to be made during installation, the cost of shipping such long sections may make it more expensive to deliver. Pipe sections can be joined together by using inset-off-set with barrel clamp, standard spiral pipe connectors, sheet metal screws or special angle rings.

Most of the non-pipe components used in conjunction with spiral pipe are constructed using the same methods (sheet metal manufacturing) as those used with flanged duct, airtight tubing and clamp together duct. The connection ends of branches, elbows, gates, etc. are simply constructed to accommodate the spiral pipe.

Performance

i) The spiral duct machine is divided into molding type of rolling cutting and steel strip of saw cutting.

ii) The molding of corresponding size must be used for each size of spiral air pipe.

iii) For the steel strip type, adopt different specifications and lengths of steel strip, can process the corresponding size of air duct.

iv) Special mould for various tube diameters, very easy to change and adjust without needs of crane or too much manpower.

v) High speed synchro flying cutting system with PLC control to handle bulk orders.
