We remain as the biggest manufacture company in the world is about 20% of all
manufacturing of all worlds. Hope fully us will must be largest producer of oil but the
fact is discovered with the invention of technology will frequent result largest
reserves & oil production number of any country on our planet little.
During the oil- producing & it moving or using period many of quantity pipe are use or
involve wilder quantity .High frequency welded ERW pipe produced with a welding
current frequency equal to or greater than 70 kHZ. Through high-frequency current
welding resistance, the heat generated in the contact objects, so the objected surface
are heated to the plastic state, then with or without forging to achieve a combination
of steels. High frequency welded is solid resistance heat energy. The high frequency
current pass through the metal conductor, will produce two peculiar effects, skin
effect and proximity effect. High frequency welded (HFW) pipe Manufacturers
process is to use the skin effect to concentrated on steel object surface, use
proximity effects to control the position and the power of the high-frequency electric

2. current flow path. Since the speed is very high, the contacted plate edge could be
heated and melted in shore time, then extruded through docking process
Advantage of High frequency welded pipe in the welding process, High frequency
welded steel pipes do not need to add filling Meta. So it has fast welding speed and
high efficiency in production. High frequency welded pipe is widely used in the fields
of oil and gas transportation, oil well pipeline, building structure and various kinds of
mechanical pipe. However, High frequency welded steel pipe quality is affected by
many factors, such as raw material and process. And the production quality control
becomes difficult. So the yield and welding process still need to be improved
continuously.
A seamless tube is a tube that does not have any welding seam. The seamless tube will
ideally be a solid metal tube with each end connected to another tube without having
any welding joint. These tubes have threads either at one end or at both ends and can
be threaded to the end of another hollow tube or pipe. The presence of any seam on a
welded tube acts as a weak point, however if the tube is seamless, it tends to be solid
and overcome various industrial forces and pressures while in operation. A seamless
tube may also be known as a seamless pipe.
Seamless Tube A seamless tube can be made from any of several alloys and metals
such as carbon steel, stainless steel, molybdenum or tungsten. Seamless tubes are used
in those industrial applications that mandate the highest safety requirements. In order
to produce a seamless tube, a solid block is penetrated by a piercing plug before the
tube is drawn to its desired size.
A seamless tube is extruded and drawn from a billet whereas a welded tube is produced
from a strip that is roll formed and welded to produce a tube. Since a seamless tube

3. offers a higher range of safety measures it is more expensive than a welded tuba
seamless tube is relatively short in length, whereas welded tubes can be manufactured
in long continuous lengths. A seamless tube generally doesn't show any sign of corrosion
until and unless it is subjected to a highly corrosive environment, whereas the weld
area in the welded tube is much more prone to corrosion attacks.
A welded area is considered to be inhomogeneous, thus it exhibits a different
malleability and less corrosion resistance as well as greater dimensional variation. A
seamless tube eliminates any such issues and thus offers high corrosion resistance.
