#56 90 (10) ALUMINUM ELBOW - Long Radius Aluminum Elbows

ITW Insulation System's polyfilm lined aluminum elbow covers are made in two precision formed matching halves to cover and weatherproof insulated 45 deg and 90 deg pipe elbows. These elbow covers are called Ell-Jacs Plus by ITW Insulation Systems. Like ITW aluminum jacketing, Ell-Jacs Plus are a premier protective outer surface for insulation systems on pipe and are an excellent performing and critical accessory to complement the aluminum jacketing. Ell-Jacs Plus protect the insulation and underlying pipe from physical damage, UV exposure, corrosive atmospheres, and water. They also reduce the time and labor needed to install the metal jacketing system. Ell-Jacs Plus have a 3 mil (76 micron) three layer polyfilm moisture barrier (PFMB) that is factory heat laminated to the interior surface. When coupled with the ultrapure alloy used in these elbows, this moisture barrier reduces pitting/crevice and galvanic corrosion potential of the interior surface of the elbow cover and the underlying pipe. Ell-Jacs Plus have a factory applied and baked on finish of highly durable hard film clear acrylic or polyester paint on the exterior surface to help resist external corrosion and to raise the emittance. The special paint used on the exterior surface of EllJacs Plus is chalk and fade resistant. It exhibits better resistance to oxidation and to the effects of various corrosive environments than bare aluminum jacketing. This painted surface also resists water, scratching, and fingerprint staining.

Piping is an essential part of many industries around the globe, and elbows are one of its vital components. An elbow is a pipe fitting used in plumbing works to change the pipe direction by a certain degree, such as 45 or 90 degrees. Here, we’ll discuss one of the most commonly used elbow types, the 90 Degree Elbow. We will dive into its properties, composition, and uses. So, let’s get started!

What is 90 Degree Elbow?

A 90 degree elbow is a plumbing fitting designed to change the direction of a pipe by 90 degrees. The most common types are the long radius (LR) and short radius (SR) elbows, typically manufactured from steel, brass, chrome alloy, stainless steel, or plastic materials. It is commonly used in residential and commercial applications. Its construction can vary depending on what material it is made from, its size, and its pressure rating.

Properties 90 Degree Elbow

Mechanical Properties:

1. A 90 degree elbow is a pipe fitting installed between two pieces of pipe to change the flow direction.
2. 90 degree elbows are available in various materials, including brass, copper, plastic, and stainless steel.
3. The most common type of 90 degree elbow is the 90 degree elbow with a female National Pipe Thread (NPT) connection on both ends.
4. 90 degree elbows are also available with other connections, such as solder, sweat, or threaded connections.
5. When selecting a 90 degree elbow, it is important to consider the material, connection type, and maximum pressure rating.

Chemical Properties:

• The 90 degree elbow is a pipe fitting installed between two pieces of pipe to change the flow direction.
• The most common use for a 90 degree elbow is to connect two pieces of pipe running in different directions.
• A 90 degree elbow is also used to connect two pieces of pipe running in the same direction but at different angles.
• A 90 degree elbow is classified as a long-radius elbow or LR elbow if the radius of curvature is 1.5 times the diameter of the pipe.
• A 90 degree elbow is classified as a short radius elbow or SR elbow if the radius of curvature is less than 1.5 times the diameter of the pipe.

Composition of 90 Degree Elbow

As mentioned earlier, different materials can be used to make 90 Degree Elbows. Carbon Steel elbows are used in low to medium temperatures and are suitable for transporting dry and non-corrosive gases. Stainless Steel Elbows, on the other hand, are ideal for piping corrosive liquids or high-temperature applications that other materials might not withstand. Meanwhile, due to their chemical resistance, PVC and CPVC materials are primarily useful in drainage systems and low-pressure delivery systems.

Uses of 90 Degree Elbow

90 Degree Elbows have diverse applications in different industries, such as plumbing, power plants, chemical plants, oil and gas refineries, and HVAC systems. One of its primary uses is as a connector to distribute water supply. It is also used to deal with the gas or liquid transportation process that requires diverting or redirecting the fluid flow direction. The elbow is also used where the pipes pass through tight or restricted spaces such as walls and ceilings to change their directions.

Conclusion:

In conclusion, a 90 Degree Pipe Elbow is an essential fitting used in pipes and plumbing systems to change the direction of pipes by 90 degrees. Its composition varies depending on the type of material used, making it perfect for many applications, such as power plants, chemical plants, oil and gas, and many more. The 90-degree elbow’s properties, such as durability and corrosion resistance, make it a versatile pipe fitting that plays a significant role in connecting, redirecting, and changing the direction of piping systems. Whether working in an industrial plant or a homeowner looking to upgrade your plumbing system, understanding 90 Degree Elbows is essential to choose the correct pipe fitting for your next project.
