What is Stainless Steel Flanges?
Stainless steel is one of the most popular materials and the flanges made with it are widely used in different applications across various industries. The stainless steel flanges possess superior physical properties, like good resistance to corrosion, increased durability, etc. These flanges are used for both industrial and domestic purposes, and they offer the required support to the piping system. Also, one can easily find different grades of stainless steel and they vary in their chemical composition. It means that the properties possessed by different stainless steel grades might also be different. There are several choices of flanges and each has varied applications. To choose the right variety from among these, clients can consider the following four factors:
Joints and welds are the critical points in a pipeline and thus, it is essential to thread them carefully. Apart from choosing the right type of stainless steel flanges, it is also important to select the right grade of the fittings, even if it costs a bit more.
The properties of stainless steel flanges are unique and that is what makes them so popular across several industries. They are resistant to corrosion, highly durable, and can effectively withstand high temperatures. They can last for several years and require very less maintenance. They are indeed one of the most cost-effective choices as a piping accessory.
What are Stainless Steel Pipe Flange used for?
There are a wide range of flanges available in the market, and due to their unique structure, each has varied usage.
Stainless Steel Lap Joint Flange Vs Ss Slip On Flange
The Lap joint flanges are a type of slip-on flange that comes with stub-end fittings. They are great for piping systems that need regular inspection and maintenance, as they can be disassembled easily. On the other hand, the slip-on flange is like a ring placed over the end of a pipe. This means, they must be slid into the pipe before welding. They are suitable for low pressure applications.
Thus, it can be said that the stainless Steel Lap Joint Flange is quite similar to the SS slip-on flange, but the main difference is in the curved radius at the bore and face. For the former, there is a place to house the lap-joint stub-ends. Due to these characteristics, they are widely used in places where frequent dismantling of the pipes are required.
How do you measure Stainless Steel Weld Neck Flange?
The stainless steel weld neck flanges square measure the flanges that are designed for joining the piping system through the process of butt fastening. They are a bit high-priced, given their long neck but they are widely used for high stress applications. The neck helps in transferring the stress to the pipe, which reduces the stress concentrating to the end of the WN flange. The bore of these flanges are customized in terms of size according to the bore of the pipe. This helps in easy fitting, and the turbulence and erosion is also reduced.
The weld neck flanges are mostly used in pipes instead of the pressure vessels. They are available in two types, regular and long. Being available in different designs and sizes, they are able to cater to a wide range of applications. The regular ones are used with the buttweld fittings, and it helps in connecting two pipes. The long WN flanges are used with vessel nozzles or equipment, and they are rarely used with pipes. The dimension of the weld neck flange varies with the class; clients can get the full list by asking the manufacturers.
What Grade Of Stainless Steel Plate Flange Will Not Rust?
Stainless steel flanges are popular around the world due to their corrosion resisting properties, but it is essential to remember that different grades of stainless steel offer different levels of corrosion resistance. Grade 304 of stainless steel plate flange is the most resistance to corrosion and thus are not likely to rust. They have a high amount of chromium which is responsible behind this property. Grade 316 is similar to Grade 304, but the former has molybdenum added to its chemical composition, which further enhances the corrosion resistance properties. Even though ferritic and martensitic steel are more affordable compared to the austenitic steel, their corrosion resisting priorities are also lower due to the presence of less chromium and nickel in their chemical composition. Duplex steels can be used in these cases, as they are used to avoid stress corrosion cracking that are mostly associated with the austenitic steel. However, it is essential to remember that even the lower grade of stainless steel will not rust due to the interaction between its alloying elements and the environment.
