PTP's aluminized pipes are produced from cold rolled steel sheet
with a hot-dip aluminium silicon alloy of selected thickness coating.
This material is much superior in quality for exhaust applications
and it's life expectancy is much longer compared to normal cold rolled
steel pipes or hot rolled steel pipes.
The special features of aluminized pipes for exhaust applications are
as follows:-
| 1. |
HEAT RESISTANCE
Due to its coating, aluminized materials has excellent heat resistance.
No alteration in the coating is observed up to 450�C. At higher
temperature, the formation of an iron/aluminium alloy gives the
coating a greyish appearance and can be used up to 600�C. Since
this alloy layer has a high fusing point it will not melt even
if exposed to a temperature above the fushing point of aluminium.

| 2. |
MECHANICAL STRENGTH
The tensile strength is 30kgf/mm and elongation 34%, which is best
suited for bending, bulging, swaging and lock forming.
|
| 3. |
REFLECTIVITY
Aluminized material reflects the incident radient heat. This property
allow its use as an efficient thermal barrier or heat reflector
in many high temperature applications.
|
| 4. |
CORROSSION RESISTANCE
Providing good corrosion resistance in auto exhaust system and
industrial acid chemicals but less resistance to industrial alkaline
chemicals.
|
PTP produces a range of aluminized pipes
ranging from Outside Diameter 12.7mm up to 85.0mm with thicknesses varying
from 1.0mm to 2.4mm. A special techniques is applied to control the
inner bead height which is made possible by sophisticated techniques,
which is convenient for Bending, Swaging, Bulging, Lock Forming application
with less wear and tear on tooling used.
