What Is Stainless Steel Pipe Fittings
The stainless steel pipe fittings are made of an alloy called stainless steel. It is very durable and is highly corrosion resistant. The stainless steel pipe fittings are also known for their cryogenic toughness. They are used across several industries due to their unique properties, like it offers good resistance in high temperatures, and possesses high fabricability and transformability. The stainless steel is available in different grades like 304, 316, and 316L, and each of them offer some unique characteristics.
Stainless steel fittings are basically used for connecting pipes. They also help to control the occurrences going on inside the pipe, like the volume or direction of the liquids, or the pressure of the flow. Depending on the purpose for which it would be used, there are different types of fittings available for piping, plumbing and pressure applications.
Some of the most common types of stainless steel pipe fittings are:
- Pipe Tee Fittings- These are T-shaped fittings with two outlets present at an angle of 90 degrees and only one inlet. It is popularly used across several industries.
- Cross Fittings- These fittings are shaped like a cross with three inlets and one outlet, or vice-versa. These fittings come handy in small spaces where not much area is available for fittings.
- Elbow Fittings- They are mostly used for changing the direction, pressure and volume of the liquid flow. The sharp bent of this fitting helps it to perform the function.
- Reducer Fittings- They have a big diameter and a small diameter on each end, and they are mainly of two types; concentric reducer and eccentric reducer.
What Are Stainless Steel Buttweld Fittings Used For?
Stainless Steel Buttweld Fittings are designed in such a way that needs to be welded on site. It helps in connecting pipes together, and also allows change in the flow direction. The SS buttweld fitting also helps in changing pipe diameter or its branching. They are mainly used in process operations in various industries. The SS buttweld fittings are popularly used in chemical plants, pharmaceutical plants, breweries, food processing units, cryogenic plants, waste treatment facilities, commercial nuclear power plants and so on. The buttweld pipe fitting helps to join the pipes in a straight line, and change or divide the fluid flow. With the buttweld pipe fittings, clients can expect to reduce their production cycle as well as their production cost.
What Are The Types Of Stainless Steel Weld Fittings?
There are four types of stainless steel weld fittings, namely:
- Butt weld fittings- These are the pipe fittings that mainly help in changing the direction of the flow. It also helps in branching of the pipes, reducing the size of the pipe, and attaching the auxiliary equipment. They offer more robust connection, and as they have a continuous structure, it helps to add strength to the whole piping system. They also offer a seamless flow inside the pipe.
- Threaded fittings- The threaded joints are the oldest methods of connecting the pipes. They help to change the direction of the flow, and also connect all the equipment that will help in operating the whole system without any interruptions. The threaded fittings are generally available in the standard dimensions.
What Is The Difference Between Stainless Steel Socket Weld Fittings And Stainless Steel Butt Weld Fittings?
For the socket weld, there is a recessed area of the fitting where the pipe gets inserted. Both the pipe and the fitting here have a square cut, and there is no need for a beveled end, which helps in easy welding and installation.
The Stainless Steel butt weld fittings with the same thickness as that of the pipes, have its ends welded to the ends of the pipe. It is important for the butt weld fitting ends to be beveled.
There are many points that differentiate the socket weld fittings from the butt weld fittings, like:
Applications
The socket weld fittings are primarily for pipes with a diameter of NPS 2 or smaller. They are ideal for smaller lines.
The butt weld fittings come with a greater strength, and they are capable of withstanding high temperature and pressure. That is why these fittings are used for bigger pipelines.
Features
The socket weld fittings are very easy to install, but it requires a gap of about 1/16” at the bottom for thermal expansion. The gap might cause stress problems cracking the fillet weld of the fitting. They can cause trouble in corrosive fluids due to the occurrence of crevice corrosion. And because of the absence of smooth pipe internals, the chances of corrosion is also high.
But when it comes to strength, corrosion resistance, temperature compliance, and fatigue, the butt weld fittings offer the best results. The only problem with this fitting is that they are difficult to weld. More time and efficient labors are needed to do the welding work properly.
Price
Normally, similar sized socket weld fittings cost higher than the butt weld fittings. However, the overall cost of butt weld fittings is more due to the installation process. It requires skilled laborers and hence the costs are higher.
Benefits Of Stainless Steel Fittings
The stainless steel fittings offer a wide range of benefits:
- It is high in strength and offers excellent resistance to corrosion. It is also resistant to heat and chemical damage. Along with withstanding high flow rates, the stainless steel fittings can also withstand various elements in different types of environments.
- Stainless steel is safe and thus they can be used in all types of liquids, including drinking water for public supply. It is resistant to a wide range of potable waters including different levels of chloride. Apart from being fully recyclable, they also retain a higher residual scrap value compared to ordinary steel.
- Apart from these, the stainless fittings also need low maintenance. Whether it is used for an indoor or outdoor application, no additional coatings are needed on it. They are very durable and can last up to 50 years. They also come with a reduced downtime, and it does not need much replacements and maintenance over its lifetime. It is a cost-efficient fitting that has a wide range of applications.
