Steel Pipes
manufactures and Exports huge range of ERW
Galvanized Steel Pipes. For pipes or tubes size 4
inch (10.2mm) OD and below, strip is fed into a set
of forming rolls which consists of horizontal and
vertical rollers so placed as to gradually from the
flat strip in to a tube which is then allowed to
pass the welding electrodes. The electrodes are
copper disks connected to the secondary of a
revolving transformer assembly. The copper disk
electrodes make contact on each side of the seam and
temperature is raised to the welding point. Outside
flash is removed by a cutting tool as the tube
leaves the electrodes, inside flash is removed
either by an air hammer or by passing a mandnel
through the welded tube after the tube has been
cooled. This is termed as Electric
Resistance Welded or ERW tube/pipe.
ERW pipes are used in Water Pipelines, Agriculture
and Irrigation (Water Mains, Sewerage Systems,
Industrial Water Lines, Plant Piping, Deep
Tube-Wells & Casing Pipes). Other popular
application area includes usage in gas pipe lines
(pipe lines for natural gas, LPG and other non-toxic
gases). The SW is meant for shallow water
applications This could be in a canal, natural
stream, culvert, or pipe.
ERW Galvanized Pipes &
Tubes
has long been one of the most used building
materials in the world. For decades, designers,
builders & consumers seeking long term structural
performance, in the tuff outdoor applications, have
turned to zinc coated steel pipes. ERW Galvanized
Pipes resist the attack of wild, water & road
salts.
ERW Galvanized Steel
if the one, that’s been covered with a layer of zinc
metal. During galvanizing, steel is immersed in a
molten zinc bath, ensuring a tough, uniform barrier
coating. Zinc’s natural corrosion resistance
provides long-term protection, even in outdoor
environments.
Apart from preventing water corrosion, it is equally
effective in dry & indoor environments also.
ERW Galvanized pipe
is steel pipe covered with a protective coating of
zinc that greatly reduces its tendency to corrode
and extends its life expectancy.
It may be used in residential water supply lines,
but not gas lines because natural gas causes the
zinc to flake off and clog the system.
It's not frequently used for water supply lines
because the minerals in the water react with the
galvanizing material and form scale, which builds up
over time and will eventually clog the pipe.
ERW Galvanized pipe was commonly used for
water supply lines many years ago, but over time
many have filled with scale, which is why some older
homes suffer from low water pressure. Hard water
greatly reduces the life of steel pipe.
While it can be used for all piping inside a
building, its most popular use today is for
handrails or for replacement of existing pipe.
Copper pipe and plastic are preferred for
underground installation.
Fittings for this type of pipe are of galvanized
malleable (soft) cast iron. They connect by screwing
onto the threaded pipe, after applying a small
amount of pipe joint compound on the threads. Larger
diameter pipe is welded rather than threaded.
Galvanized pipe is cut either with a heavy-duty tube
cutter or cutoff saw, or by hacksaw
It is sold in the same standard 21-foot lengths.
Connectors and fittings are screwed onto the pipe,
after applying a small amount of pipe joint compound
onto the pipe threads. It is cut either with a
heavy-duty tube cutter or cutoff saw, or by hacksaw.
