In recent years, driven by the rapid growth of China’s economic fluctuations, the domestic flat welding flange industry layout is very rapid. In daily and industrial use, flat welded flange with neck is increasingly driven by its energy saving and reliability, and plays a functional and irreplaceable function.
Huge market, there must be a strong competition situation. Compared with previous years, there are too many companies in the industry today, and the competition for product promotion is too strong.
Flange trend with neck flat welding
Due to the growth of the economy, the use of flat welded flanges with neck is also more and more wide, the stainless steel surface passivation layer corrosion level analysis, integration of professional production technology and facility use, production and processing of flat welded flanges, not only consider the needs of daily production and processing life, but also fill the domestic vacancy.
Today’s society is an information age, and it is inevitable for enterprises to face competitors in the product, and there is competition in the industry, which is a good thing for many enterprises.
Due to ownership competition, enterprises enhance the quality of products, enhance the quality of services, and buyers also get better or more deals and services for less money.
When the industry is growing and improving, the market is also in the survival of the fittest enterprises in the industry. For many influential large enterprises, according to the competition, the scale of enterprises has become larger and larger, and the fame has become higher and higher.
With the rapid development of the domestic flat welded flange market, the use and development of the corresponding core production technology will eventually become the focus of attention of the industry enterprises.
In order to occupy an important position in the market, manufacturers of neck flat welding flanges must constantly expand new applications, enhance brand upgrades, and face strong competition.
With neck butt welding and welding difference
Flat welds cannot be radiographically inspected, but butt welds can. The butt weld of the neck of the flange and the weld of the tube is a ring seam. Flat welding is two fillet welds, butt welding is butt ring welding.
The difference between a plain welded flange with a neck and a plain welded flange without a neck is that a plain welded flange with a neck has more welding parts in the pipe than a plain welded flange without a neck. In one place, the flat welded flange without a neck is also a flat flange, and the boss without a flange is also flat fillet welded.
The weld between the neck butt flange and the connecting pipe belongs to class B seam, and the weld between the neck flat welding flange and the connecting pipe belongs to class C seam, and the non-destructive testing after welding is different.
