Description
POLYLOCK APPLICATION
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..
