Mechanical Seals – Example of Seal Types Under These Industrial Products

Ann Arbor Real Estate information

Seals are generally important in order to prevent leakages in products. When speaking of mechanical seals, expect that it is used in order to serve that very same purpose in plumbing systems. These devices are also highly favored in joining mechanisms together the same way that adhesives work. The device commonly contains pressure while getting rid of contamination in the process.

Mechanical seals work with the help of a rotating shaft. The housing of the seal works extremely well under different speed and temperature settings and is capable of withstanding the most extreme pressures. There are single acting and double acting seals. Seal types include induction sealing, adhesive and sealants and flange gaskets. Learn about these three through the following paragraphs.

Induction sealing

Also known by the name cap sealing, induction sealing is one that adapts a non-contact heating method. A metallic disk works on top of glass and plastic containers and the sealing transpires once the container is filled with the material and capped accordingly.

The most recent developments in induction sealing allows for the utilization of a foil sealed to the container. This eliminates the usage of a closure. The foil is either reeled or pre-cut and is placed and pressed down to the material. This activates the induction process thus bonding the seal to the container. This development is known as capless induction sealing.

Adhesive or sealant

A sealant is commonly described as a viscous material that has the capacity to change its state to a solidified form. This is used in order to prevent air, dust, gas, smoke and liquid penetration. The most common applications for seals include concrete and drywalls. Sealants are insoluble, corrosion resistant and have the best adhesive traits. Construction, aerospace and automotive industries benefit much from the use of these mechanical seals. Its main distinction from the adhesive is seen on the fact that sealants are not as strong as the other.

Flange gasket

Flange gaskets are mechanical seals that are used in order to provide a higher surface area to the sections of a pipe. They come in various sizes and are commonly bought depending on the diameter of the product. Included in the list of flange gaskets are sheet gaskets, spiral wound gaskets and ring gaskets. Sheet gaskets sometimes have bolt holes but in some instances they may operate without these holes. Spiral wound gaskets are those with stainless steel inner and outer rings. Ring gaskets are those that have different cross sections and are used in gas pipelines.
