Rupture Disks Types and Accessories

This article explains in details about the rupture disks along with their types, advantages and accessories. These are one of the important devices used for safety.

What are Rupture Disks?

These are the pressure protection devices similar to safety valves. They protect pipelines and vessels from damages like deformation, etc. The rupture disks are pressure-relief devices. These are useful in reducing the downtime of the system. These are safety devices which are highly reliable in the industries. They have a defined breaking point required for particular pressures. They come in round, square shapes, they are layered. They can be domed or flat in design. They protect machines, people and environment from pressures. Different applications need different disks depending upon the pressure requirements. Spot weld screens are also used simultaneously in the similar industries.

Rupture Disks Types

There are 3 types of rupture disks which are mentioned below:

1.       Forward-acting: these are tension-loaded disks which enable very high operating pressures. They are further classified depending upon the disk configuration as Solid Metal Rupture Disks, Scored Rupture Disks and Composite Rupture Disks.

2.       Reverse-acting: also called as compression loaded disks, they provide a good service life. They reduce the effects of corrosion which actually omits the need for vacuum support. These can operate on pressures up to 90% and a few are designed to work on 95% as well, depending upon the critical functions required in the industries.

3.       Graphite: these are Shear loaded disks. These are machined from the fine graphite bars. These are used in both vapor and liquid service. In the outside diameter of this disk, a metallic ring is usually added, it is called armoring. They have a random opening pattern. They are not good for installation on the PRV’s upstream.

Rupture Disks Accessories

For use along with these disks, there are different types of accessories available. There are alarm monitors (for raising an alarm), baffle plates (for protection of the machines and people from the burst pressures), heat shields (for reducing the temperatures), etc. that can be used along with these disks.

Rupture Disks Advantages

Rupture disks are fast in response for relieving the pressure spikes. They are simple in design, hence, fast in action. They are lightweight. They are used in both liquid and gas handling applications. There is no maintenance cost for these disks. They provide failsafe performance. The rupture disks are very economical. They are one of the most necessary safety devices.

What Are The Extruder Screen Packs Used For In Industry?

These are made up of various screens of different mesh sizes. In the filtration processes, extruder screen packs are required on a large scale. There are many types of screen packs available in the market as required for various numbers of applications. A few industries in which they are used are food, filming, chemical, petrochemical, medicine, plastic, rubber, aerospace, metallurgy, recycling, etc. Extrusion processes get easier and cleaner after using these packs. Let us see in details about the applications of extruder screen packs.

In industries, product purity is improved using an extruder screen. Filtration of contaminants requires them on a large scale. It helps to reduce the maintenance and repair cost in many operations. These are very helpful as these can’t be easily deformed and don’t even rust for a long time. They are anti-corrosive and anti-abrasive in nature. Due to their robust nature, they are used for filtration of harsh chemicals as well, sometimes. Also, they are quite durable due to many reasons. They don’t have sharp edges or acute angles. They can hold dirt under different conditions. These packs have high filtration capacity and good quality. They have smooth screening surfaces and can bear high temperatures for various applications in industries. In the operations, they provide constant quality control. They are available in a large number of sizes and specifications.

They can be a single layer or multi-layer packs. Depending on the materials used, these packs differ. The materials used in them are stainless steel, black wire cloth, galvanized steel, brass wire, nickel alloy, etc. Also, their shapes can vary as per the applications. They are available in circular shape, oval, square, disc, cone and similar other shapes. They are also categories as perforated, woven, pleated, expanded metal, sintered, etc.

While choosing a good extruder screen you need to consider these few things- corrosion-resistance, screen materials, durability, screen mesh, wire diameter, weaving type, opening percentage, etc. Also, about the material choice, usually stainless steel and nickel alloys make the best choice. Your extrusion system will work great when you choose the extruder screen wisely.

So, these were a few points on the uses of these screen packs and choosing wisely.
