What should be noted when using stainless steel forged flanges?
Stainless steel forged flanges are components in piping systems that serve to connect various pipe sections. However, there are many types of flanges, and their standards are quite complex. So, what should we pay attention to when using stainless steel forged flanges? Today, a flange manufacturer from Wenzhou is here to share some tips with you!

Wenzhou flange manufacturer shares what types of flanges there are.
In the 21st century, flanges have become one of the key components in the chemical industry, oil refining, and pressure vessel fields. Flanges come in different materials; one type is made from solid-forged material, typically using grades 304, 316, or 316L, while the other type has a relatively rougher surface texture. So how are flanges classified? Let’s hear from a flange cap manufacturer in Wenzhou. The classification of flanges is primarily based on the connection method between the flange and the pipe, and can be specifically divided into the following types:

What is a flange?
Flange connections are an important method of joining pipes in pipeline construction. A flange connection involves first securing two pipes, pipe fittings, or equipment pieces onto separate flange plates. Then, a gasket is placed between the two flange plates, and the assembly is tightened together using bolts, thereby completing the connection. Some pipe fittings and equipment already come equipped with integral flange plates, which also fall under the category of flange connections. Flanges can be classified into threaded (screwed) flanges and welded flanges. For low-pressure, small-diameter applications, screwed flanges are commonly used; whereas for high-pressure and low-pressure, large-diameter applications, welded flanges are preferred. The thickness of flange plates and the diameter and number of connecting bolts vary depending on the pressure rating. Depending on the different pressure levels, flange gaskets are made from various materials, starting from low-pressure...

Bravely venturing into overseas markets is the current path for enterprise development.
With the development of China’s economy, the valve industry has also become increasingly technology-driven. Nowadays, people are no longer limited to conventional valves; more and more industries are adopting stainless steel flanged ball valves. At the same time, compared to other types of valves, stainless steel flanged ball valves have lower installation costs, higher operational efficiency, greater energy and resource savings, and easier maintenance and upkeep. As such, these valves have become indispensable components in automated control systems and are gradually becoming the mainstream products in the valve market. However, due to the industry’s low level of concentration, numerous adverse factors have emerged—such as technological backwardness, cutthroat price competition, and a lack of influential brands—resulting in the vast Chinese valve market remaining...

Analysis of the Development Prospects of the Flange Gate Valve Market
In recent years, as the market economy of gate valves has continued to evolve and change, China’s domestic gate valve market has also experienced fluctuations. The economic market has never been particularly stable—both domestic and international conditions have been similarly volatile—and the flanged gate valve industry has seen a relative decline in exports. However, over the next 5 to 10 years, as China’s overall strength continues to grow and the upcoming G20 Summit (an international forum for economic cooperation) gets underway, the country’s overall economic level is expected to show an upward trend. At the same time, the mechanical gate valve industry will gradually begin to recover. In the coming years, according to analyses by industry experts, the development of the gate valve sector will increasingly focus on flanged gate valves—a major product category. Flanged gate...
