Yes, Flexaseal’s edge-welded bellows are completely manufactured at our Vermont factory. Our welding department and engineering staff work closely together to control the manufacturing quality of all bellows assemblies, from stamping sheets of foil stock through welding cores and end fittings, evaluating spring rates, and pressure testing the completed assembly. We use the TIG (Tungsten Inert Gas) welding process which provides the finest control of the weld arc, resulting in efficient, clean, and long-lasting welds.

Formed bellows are manufactured from either welded (seamed) or seamless tubing and utilize extensive automation for mass production. This process offers some cost benefits over edge-welded bellows assemblies however, formed bellows are limited to materials which can be elongated through either rolling or hydroforming. Formed bellows typically have thicker convolution structure with higher spring rates and larger deviations than edge-welded bellows which impacts precision loading.

Flexaseal designs and manufactures edge-welded bellows. Our bellows production begins by stamping male and female diaphragms from sheet (foil) stock. We inventory foil stock including various Hastelloy™ and Inconel® grades, titanium and Monel® as well as cryogenic-grade materials, to accommodate a wide range of applications. Diaphragms are TIG-welded together to create a convolution, and these convolutions are assembled together and welded to create the bellows core. Bellows core sizes can range from just a few welded convolutions to 100+ convolutions for a hermetic bellows assembly.

Contrary to popular belief, it is possible to repair a rotary bellows assembly. If pressure testing reveals leakage around the seal face, Flexaseal will de-insert the current face and check the retainer for any damage. If the retainer is within the necessary tolerances, FAS will insert a new face into the assembly as well as replace the other wear parts (O-ring and hardware).

If the bellows rotary shows visible damage to either the bellows core or end fittings, or a pressure test reveals leaks in the assembly itself, Flexaseal recommends a new bellows assembly to ensure sealing integrity.

In a pusher seal design, the secondary sealing component – usually an O-ring or a wedge — must move axially to compensate for wear, vibrations, and movements of the shaft.

Welded bellows assemblies also offer the benefit of an inherently balanced seal design. Mechanical seal balance refers to the ratio of the opening and closing areas of the seal faces. Both a balanced and unbalanced design may have the same opening face area but the balanced seal’s closing area is smaller, reducing the load on the faces. This reduced load means less heat generated at the seal faces, enabling the balanced seal to run cooler than an unbalanced seal design. This cooler operating environment positively impacts a seal’s run time.

If your facility must comply with API Standard 682 which requires all Type B or C cartridge seals to utilize a balanced seal design, standardizing on hydraulically balanced, welded metal bellows seals ensures satisfactory seal run time and low seal maintenance for your equipment.

Operating length (OL) - also referred to as installed or working length: The axial length of a bellows assembly as installed to the designed compression. The term may also refer to the dimensional range within which a bellows assembly can safely be operated.

Mechanical seals, whether a pusher or bellows design, need a specific amount of compression to ensure the faces are in contact to maintain the correct amount of lubrication to operate (dry-running seal designs are the exception to this statement.) Both the Free Length and Operating Length are necessary for this compression calculation: Free Length – Operating Length = amount of compression. Here’s an example:

Bellows Mechanical Seal are a type of mechanical seal where the spring element is a bellows. This eliminates the need for a secondary dynamic seal e.g o-rings. Bellows Mechanical Seals are also known as non-pusher seals as they have a static secondary seal which stays in place against the shaft, sleeve or on the gland of the pump.

A bellows mechanical seal is used where a dynamic seal is deemed unsuitable for the application e.g high temperature medium slurry or high seal hysteresis.

The primary mechanical seal functions exactly the same as a standard mechanical seal except the spring element is now being replaced with a bellows. The friction from the dynamic seal (e.g o-ring) is not a consideration.

However if a bellows mechanical seal should fail it can be due to several reasons such as; poor wielding, product particulate getting into the bellows and causing the spring element to fail, chemical and/or abrasive attack or over-pressure.

A dry gas seal is a revolutionary way of sealing machines and protecting them from dust, moisture and other contaminants. A dry gas seal is a sealing device that uses pressurized gas to keep two surfaces from touching. The most common type of dry gas seal is the O-ring, which is used in many applications, including mechanical seals, piston rings, and gaskets. Dry gas seals are also used in many other industries, such as the food and beverage industry, where they are used to seal containers and prevent contamination. This type of seal not only helps to keep the machine running with maximum efficiency but also significantly reduce downtime, making it cost-effective in the long run. In this article, we"ll explore what a dry gas seal is, how it works and why you should consider using it for your machinery. By understanding the benefits of a dry gas seal and its uses, you can make an informed decision about the best sealing system for your needs. How does a dry gas seal work?Dry gas seals work by using a series of labyrinths to separate the high pressure seal gas from the atmosphere. The labyrinths are formed by a series of grooves and ridges on the surface of the seal ring. The seal ring is rotated at high speed, causing the gas to flow through the labyrinths. The gas is then forced through an aperture in the center of the seal ring, where it escapes into the atmosphere. What is a dry gas seal used for?Dry gas seals are used on rotating equipment to help minimize the leakage of high pressure gases from the inside of the machinery. This helps to reduce maintenance costs and improve safety. Dry gas seals are commonly used in applications such as pumps, compressors, turbines, and blowers. Advantages of a dry gas sealThere are many advantages of a dry gas mechanical seal. One advantage is that they are much simpler in design than other types of seals, making them more reliable and easier to maintain. Additionally, dry gas seals do not require the use of any lubricating fluids, which can leak or evaporate over time. This makes them more environmentally friendly and cost-effective in the long run. Finally, dry gas seals have a much longer lifespan than other types of seals, meaning that they need to be replaced less often.Disadvantages of a dry gas sealThere are several disadvantages of dry gas seals, including: - they can be expensive to purchase and install- they require careful maintenance and regular inspection- they can be susceptible to wear and tear- they can leak if not maintained properlyHow to choose the right dry gas seal for your applicationThere are a few key factors to consider when choosing the right dry gas mechanical seal for your application. The most important factor is the type of fluid being sealed. Gas seals are designed to seal either liquids or gases, but not both. Make sure to choose a gas seal that is compatible with the fluid you are sealing.Another important factor to consider is the pressure of the fluid being sealed. Gas seals are rated for different maximum pressures, so make sure to choose one that can handle the pressure of your application.Finally, take into account the size and shape of the sealing surfaces. Gas seals come in a variety of sizes and shapes to fit different applications, so make sure to choose one that will fit your needs.ConclusionDry gas seals are an extremely important component for many industrial operations, and their ability to prevent leaks has made them invaluable in a variety of applications. Understanding the basics of how dry gas mechanical seal work and how they can be used effectively is helpful when considering the various options available for any specific application.
