Flanges for pipe system
Flanges are used to connect valves, pipes, pumps and other equipment to form a piping system. Typically, flanges are welded or threaded, and the two flanges are connected together by bolting them with spacers to create a seal that provides easy access to the piping system. This flange has many different types. Below are the types of flanges clearly classified according to each specific purpose, for you to choose easily.
International Standard for Flanges
Different Types of International Standard for flanges, we can produce:
-
- ASME Standard Flanges
- JIS Standard Flanges
- ASTM Standard Flanges
- DIN Standard Flanges
- BS Standard Flanges

304 Stainless Steel Flange
304 is a relatively versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In China, 304 steel is called 0Cr19Ni9 or 0Cr18Ni9 stainless steel, as 304 contains 19% Cr and 9% Nickel.
Application of 304 stainless steel flange
As 304 stainless steel is a widely used chromium-nickel stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It has corrosion resistant in the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for processing, storage and transportation of food. Has good processing properties and weldability. Used in plate heat exchangers, bellows, household goods, building materials, chemicals, food industry, etc.

316 SS Pipe Flange
Compared to 304 stainless steel, 316 stainless steel material have additionally of Nickel and Molybdenum, which in China called 18Cr-12Ni-2.5Mo steel. So normally it has extra Mo 2.0 to 3.0 percent than 304 steel. And this Mo is an element to offer better resistance for high temperature.
Application of 316 stainless steel flange
316L stainless steel flange has good anti-corrosion effect, better than 304 in seawater and other various media. So it is also regarded as ”marine grade” stainless steel, but it is not resistant to warm sea water.
316 SS flange used for equipment resistant to sulfuric acid, phosphoric acid, formic acid and acetic acid. Applications include marine, pumping, chemical production, food industry, irrigation, and other stainless steel pipeline systems.
Connections Types for Stainless Steel Flanges
Stainless steel flanges also ranged with slip on flange, weld neck flange, blind flange, socket weld flange and threaded pipe flange. Generally they could be called stainless steel pipe flange, or stainless steel plate flange.

ROTARY BROACHING
Stainless steel is a corrosion-resistant alloy of iron, chromium and, in some cases, nickel and other metals. Because of the excellent of stainless steel, our flanges of TDB is completely manufactured in inox SUS304, inox SUS316.
Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
On contact with oxygen, a chromium oxide layer is formed on the surface of the material. This passive layer protects it and has the unique ability to repair itself.
Advantages of stainless steel for manufacturing flanges & fitting
- Highly durable
- Excellent corrosion resistance
- Completely and infinitely recyclable
- Use in difficult metal forming modes (deep stamping, flat bending, extrusion, etc.)
- Environmentally neutral and inert
- Good mechanical behaviour at both low and high temperatures
- Aesthetically appealing
- Extremely hygienic
- Easy to maintain
- Resistance to Fire

WHAT IS FLANGES?
An Industrial Pipe Flange can be a collar, ring or solid disk that attaches to various pipe applications that allow or restrict the flow of liquids and gases. Pipe Flange installment is usually completed by welding the Flange onto the pipe but the Industry also offers Threaded and Lap Joint Flanges that don’t require welding for installment.
Flange connections are achieved by drilling equally spaced bolt holes into the Flange that align with the matching Flange and then fastened with bolts. Bolt hole patterns are determined by Industry Specifications or customer request. TDB is the leading stainless steel pipe flange manufacturer in Vietnam.
HOW MANY TYPES OF FLANGES ARE UTILIZED IN THE INDUSTRY?
There are many types of flanges being manufactured for the industry but there are 12 common types of flanges that include:
- Weld Neck
- Ring/Spacer
- Counter Bore
- Blind
- Reducer
- Hub/Collar
- Lap Joint
- Threaded
- Spectacle Blind
- Slip On
- Socket Weld
- Paddle Blind

FLANGES APPLICATION
In many applications, our engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure.
Plumbing
Connecting two sections of metal piping more securely is by having flanged ends that you can connect with bolts. This way, even if gases or liquids build up to high pressures inside the pipe, it will often hold with no problem.
Mechanics
In order to connect two sections of a large, enclosed area, it is often best to used flanges and bolts. Connecting between the engine and the transmission in an automobile or any machines. By connecting the outer casings of the engine and transmission in this way, engineers protect the inner workings of both.
Electronics
Flanges have a specific purpose in other electronic devices. These flanges are usually found connecting two different materials.
