7Uses: Welded steel pipes for use in pipeline transportation system
in the petroleum and natural gas (oil & gas) industries, water
pipeline, ructural & construction.ERW pipes means Electric
Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW
steel pipes and tubes are used in various engineering purposes,
fencing, scaffolding, line pipes etc. ERW steel pipes and tube are
available in various qualities, wall thicknesses, and diameters of
the finished pipes. Our product finds its usage for Agricultural
purposes, Drinking Water for housings, in collieries for extraction
of Water, Thermal Powers, Transports, Hand pumps for deep boring
wells, as a strong protection for cables by Telecom Department,
Structural Purposes etc. While manufacturing ERW steel pipes, only
high-quality, continuous-cast, fully killed, control-rolled,
fine-grain, low-carbon steel is used. High performance ERW steel
pipes and tubing possess high strength corrosion resistance, high
deformability, high strength and high toughness. We are among the
leading manufacturers and suppliers of erw pipes and tubes in
India. We are also one of the largest exporters of erw pipes and
tubes in India. ERW pipes and tubes stands for Electric Resistance
Welded pipes and tubes. Based on the customers requirements we can
manufacture erw pipes and tubes of different size and shape. We
have a very large production capacity of erw pipes and tubes. ERW
pipes and tubes are used in various engineering purposes, fencing,
scaffolding, line pipes etc. ERW pipe is available in lengths from
single random to 120 feet depending on mill capability. ERW pipe is
available with square ends or beveled for welding, threaded and
coupled and victaulic grooved. Surface finish are available in
black or bare, or with protective coatings.
ERW pipes are manufactured starting from steel coils, that are at
first uncoiled, cut, processed, welded, and tested as shown in the
picture below.
The most common welding technique used for oil and gas pipes is the
so-called “high-frequency induction technology” (ERW-HFI),
consisting in the application of an induction current on the outer
surface of the pipe able to generate a robust seam weld and join
the two sides of the steel coil very tightly.
ERW pipes are available in sizes between 1/2 and 20 inches, in
carbon steel (ASTM A53 is the most common specification) and
stainless steel (ASTM A312). In terms of dimensions, the ASME
B36.10 and ASME B36.19 are the key reference specifications (API 5L
for welded ERW line pipes).
The ASME and API dimensional charts show typical combinations of
pipe nominal size and wall thickness (designated as “schedule”),
and show ERW pipe weight in kg (or pounds).
In the last few years, ERW pipes are have become an efficient
alternative to seamless pipes, both in terms of price and
performance, due to the modern welding technologies adopted by ERW
pipe manufacturers (example HFI and HFW, high-frequency welding).
These advancements in welding technologies have reduced, over time,
the technical superiority of seamless pipes vs ERW pipes, making
them interchangeable at least in some applications (low/medium
pressure and temperature). Of course, seamless pipes will always
benefit from the intrinsic superior mechanical strength of steel
billets vs. coils and plates.
