Weatherockgroup.com \ High frequency welded (HFW) pipe & Seamless Tubes Manufacturers 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

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

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.
