I. |
Corrosion Resistance |
|
Plain mild steel pipes are
manufactured with corrosion resistance coatings which are
factory applied. These coatings are seldom effective in
preventing the long-term corrosion and optimistic life span of
these pipes is around 20 to 30 years.
|
|
Smoothflow Pipes with its
polyethylene layers firmly bonded to the mild steel has
virtually no corrosion whatsoever and the client can safely
expect a life of more than 50 years with efficient and trouble
free service.
|
|
Polyethylene is a very inert material
and it prevents steel from various types of corrosion such as:
|
|
pitting corrosion, crevice corrosion,
galvanic corrosion, oxygen concentration cell, cavitations. |
|
|
II. |
Assured Performance
under any working conditions |
|
Smoothflow pipes have a working
temperature range between 30o to 50 o C under any working
environment thus making it a suitable pipe for many
applications.
|
|
Pipe is tested to 75% of its yield
stress value and hence gives assured performance without any
adverse effects on its structure or shape. |
|
|
|
|
III. |
High Impact Resistance & Ductility |
|
|
Smoothflow pipes are manufactured from
highly ductile steel and hence have the ability to withstand
shocks from water hammer, pressure surges and surface vibrations
from vehicular traffic.
|
|
|
Designed with a factor of safety of 3.5 on working pressure.
|
|
|
Local deformation prevents brittle failure.
|
|
|
Localized deformation is a property of
steel on account of its high ductility, whereby when a high
localized point load of large magnitude falls on the steel it
gets deformed at the point of application of the load thus
preventing total ring buckling and /or cracking as evident in
brittle pipes like cast iron, psc and asbestos cement. |
|
|
|
|
IV. |
Low Frictional Co Efficient |
|
|
The frictional lead loss depends upon
the Hazen Williams coefficient or ‘C’ value of the pipe. Smoothflow pipes have a ‘C’ value of 150 and it says constant as
there is little or no abrasion of polyethylene whether in sewage
or water supply.
|
|
|
Lower pumping costs hence significant energy savings through out
the life of pipeline compared to other conventional pipes.
|
|
|
Less frictional losses because of high 'C' value compared to
other pipes.
|
|
|
Smaller diameters can be used for same discharge because of
higher 'C' value. |
|
|
|
|
V. |
Abrasion Resistance |
|
|
Polyethylene has got the highest abrasion resistance amongst alll pipe materials.
|
|
|
Polyethylene inner lining has got good abrasion resistance in
carrying various fluids. |
|
|
|
|
VI. |
Bonding |
|
|
The external HDPE coating and the internal HDPE lining is bonded
to the Mild Steel Surface with the help of adhesives.
|
|
|
Steel reinforced HDPE pipes have the polyethylene firmly bonded
to the steel surface on the outside and inside of the pipe. This
helps in protecting the steel from corrosion, encrustation and
provides a very smooth surface. |
|
|
|
|
VII. |
High Dimensional Stability |
|
|
Smoothflow pipes are manufactured by a very flexible and highly
mechanized process which allows for minimum tolerance and hence
greater dimensional stability. Accurate thickness of coatings
and linings can be obtained as per customer specifications.
|
|
|
|
|
VIII. |
Long Life Span |
|
|
Smoothflow pipes have a service life of more than 50-75 years.
|
|
|
The coating stays integral to the pipe throughout its life span
unlike most of the other coatings in which cracking, peeling and
scraping is evident after 4 to 5 years service. |
|
|
|
|
IX. |
Ease in Location |
|
|
Another great feature of smoothflow pipes is that it is easy to
locate buried pipes. A lot of money is spend when location non
metallic pipes like psc, grp, hdpe etc. by random excavation and
in the process damaging roads and other installations like cable
conduits, gas lines etc. Smoothflow pipes can be accurately
located by ordinary magnetic locating equipments.
