Types of SS Flanges Produced

There are countless SS flanges for various applications. There are various shapes, sizes, and types of configurations to match the specific needs of the piping system. Some of the common ones are as follows:

1. Weld Neck Flanges (WN Flanges)

Weld neck flanges are the most frequently used in pipe applications. Weld neck allows them to be fabricated against pipes and, therefore, ensures a strong and absolutely leak-free joint. Gradual transition at radius from the flange to the pipe reduces stress concentrations and makes it suitable for high-pressure and high-temperature applications.

2. Slip-On Flanges (SO Flanges)

These flanges feature a design that allows them to slide onto the pipe to make installations easier and quicker. They are preferably used in scenarios where welds are undesirable but a mechanically strong union is required. Nevertheless, they typically are not as solid compared to other weld neck flanges.

3. Blind Flanges

Blind flanges are used to seal the end of either a piping system or vessel. They do not have a hole in the center and are typically bolted into place for the purpose of closing off a pipeline. These flanges are extremely important for specification of pressure-tight seals, especially during maintenance and testing operations.

4. Socket Weld Flanges

Socket weld flanges are for small diameter piping and make for a very strong, secure connection. The pipe is placed to a socket on the flange and welded in place for a very strong seal that allows very little anywhere for leakage.

5. Threaded Flanges

These flanges are used in areas where welding is impossible, meaning small pipe sizes or piping material cannot be welded. The internal threads can screw onto threaded pipes. Installation is easy.

6. Lap Joint Flanges

Lap joint flanges are used on applications requiring quick disconnection. This flange consists of two parts: a stub end and a loose backing flange. The stub ends get welded onto the pipe, but the backing flanges can be bolted onto the stub end.

7. Orifice Flanges

Orifice flanges are specialty flanges for flow meter installation. The flanges sport an integrated orifice which can be used to measure accurately the flow rate of fluids or gases. Applications are mostly developed in the oil, gas, and water treatment industries.

Materials Used by SS Flange Manufacturers

The quality of Stainless Steel used in the making of the flange is important about performance and the valuable life of it. As stainless steel offers anti-corrosion resistance, strength, and durability, stainless steel is preferred. Manufacturers of SS Flanges use different grades of stainless steel based on the environment in which operations will be carried out. Some of the common grades include:

1. 304 Stainless Steel

304 stainless steel is one of the more usable alloys for SS flanges. This alloy provides excellent corrosion resistance along with steam impact to a wide range of applications in the food processing, pharmaceutical, and numerous chemical industries. Furthermore, this alloy is highly resistant to oxidation.

2. 316 Stainless Steel

316 stainless-steel would be more representative of an advanced alloy family as it exhibits superior corrosion resistance, especially against chlorides and other chemicals that aggressively attack those materials. Marine, chemical, and pharmaceutical applications are considered some of its fields of application.

3. 317 Stainless Steel

317 Stainless steel is like 316; however, it contains added molybdenum. This grade offers good corrosion resistance and is generally found in applications where the presence of acids and other corrosive substance is high.

4. 904L Stainless Steel

This stainless steel is highly alloyed and has an excellent corrosion resistance, especially in the case of acidic media. Normally this grade is taken up in the chemical industry for jobs that call for very severe operating conditions.

5. Duplex Stainless Steel

Among the duplex stainless steels, grades 2205 and 2507 feature the best characteristics of austenitic and ferritic materials. These grades are exceptionally resistant to stress corrosion cracking, and offer excellent strength-to-weight ratios.

SS Flange Manufacturing Process

The manufacturing process of SS flanges is intricate and involves much detail in order to match up to the stern demands coming from the industries that they would be servicing. Generally, an SS Flange manufacturer follows the following steps:

1. Material Selection

It simply means selecting a proper grade of stainless steel that would be necessary to develop the required property in the final product. Difficulties may vary from industry to industry based on endurance to corrosion, strength, and temperature.

2. Forging

Most of the flanges are forged at very high temperatures to get the right shape of the steel. During forging, the material is held up with heat up to a certain temperature and then compressed into shape using dies and molds. This can enhance the material’s strength and resistance by the grain alignment in the steel.

3. Turning

When forging commences, the flange is subsequently machined to desired dimensions. Cuttings, drills, and finishes will help in proclaiming that the flanges can easily fit with the pipes and other components of the system. Bolt holes, faces, and inner bores are also manufactured to precision.

4. Heat Treatment

These flanges are often heat treated for enhancing their strength and hardness. The flanges are heated to specified temperature ranges then cooled rapidly. This process enhances the micro-structure of steel, hence enhancing anti-wear and anti-stress properties on the flanges.

5. Surface Treatment

The surface of the flanges is prepared to remove the oxidation, rust, or contaminants. Pickling, passivating, and polishing are some techniques used to enhance the clean, smooth surface with improved corrosion resistant and cosmetics.

6. Inspection and Testing

To ensure that flanges meet the standards of an industry, these SS flanges manufacturers carry out a number of quality control tests after the manufacturing process. Such tests may include dimensional checks, pressure tests, and material composition analysis. Only those flanges that pass the stronger tests are delivered to customers.
