POLYLOCK

Polylock metal flexible tubing is constructed from

BS 1449 Type 304 S 16 Austenitic Stainless Steel

by winding profiled metal strip into a tube , the strip

edges being completely interfolded . A crimp is
introduced into the strip during winding to provide a
polygonal cross - section to the finished tubing . This
ensures that the diameters remain constant when tubing
is cut , unlike plain round section tubes which tend to
spring out slightly at one end It is suitable for
temperature up to 600 ° C.
 

Polylock is well known for its strength,

durability and ability to absorb vibration and also both

axial and lateral movements . It is suitable for thermal

expansion and noise attenuation on engine exhaust

systems of vehicles and stationary plant of all kinds,

passenger and commercial road transport , ships

mechanical handling , stationary generators and etc..
