There are many variations of semi-metallic gasket available in today's market. The combination of metal and a soft gasket material merges the sealing ability of the soft material with the structural integrity of the metal.
The most common styles of semi-metallic gasket include spiral wound gaskets, corrugated, jacketed, and kammprofile gaskets.
Pumps & Systems magazine outlined the proper way to select a semi-metallic gasket.
Gasket selection suggestions
Choosing a gasket depends on a few different factors: operating conditions, fluid compatibility, mechanical features of the joint
When you're specifying a gasket for even the simplest application, it is important that the gasket supplier know all the operating parameters.
There are five major pieces of information needed to select the appropriate gasket, known by the acronym S.T.A.M.P.:
While gaskets are most often used in standard ANSI flange connections
Flange gasket storage is often an after-thought for many of our customers. While incorrect gasket installation procedures is the #1 culprit when it comes to gasket failure, gasket storage can play a large role in the quality of the gasket being installed.
Flange gaskets are highly engineered products, and their performance depends on many factors. Certainly design, manufacture, installation, and process conditions are all critical, but so is storage before use. Gasket materials often remain in storage for a long time before they are placed into service. Unfortunately, storage practices for gasket materials are generally not optimal or controlled well enough. This article provides guidance for the storage of different gasket materials to preserve their integrity.
Garlock has expanded their Ultra Low Emissions family of products to include a spiral wound gasket. The FLEXSEAL® ULE is designed for use where leakage control is critical and the aggressive application requires a spiral wound design. It’s manufactured using high performance graphite, and offers maximum protection against oxidation. The standard design includes an inner ring and outer ring, as well as preformed metal wire to enhance compressibility and sealability. The FLEXSEAL® ULE spiral wound is another product born from Garlock’s customer driven innovation.
GYLON EPIX™ is a newly developed family of PTFE gaskets. It is manufactured using a patented, profiled surface based on Garlock's proven Fawn, Off-White, and Blue GYLON® to create highly conformable materials for optimum sealing performance.
GYLON EPIX™ provides superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets that are used in worn and pitted flanges. In addition, this evolutionary material
Safety is a concern at any industrial site. An Occupational Safety and Health Administration compliance specialist has stated that safety should be more than a priority: “Priorities in an organization can and usually do change. Safety and health need to be a core value of the organization.”1
Safety can be a case of values versus priorities. When it comes to sealing devices, perceived dangers sometimes are overlooked.
The case of an explosion at a refinery in Anacortes, Washington, shows how deadly accidents can occur when safety risks
Modern technology often requires rare or ultra-pure materials that can only be handled or obtained within extreme environmental conditions. These same conditions present unique and hazardous difficulties when transporting or utilizing these resources. Resources such as liquid oxygen, nitrogen, or argon; all of which are classified as “industrial gases” are handled well below the normal temperature ranges that every-day liquids exist; ranging as low as -195.8°C (-320.4°F). This often makes it a challenging task to find a low temp gasket to fit the specifications for the application.
As an example, let’s look at argon; an important gas used in Welding, Neon Lights, 3D Printing, and Metal Production, just to name a few. It is far more economical to house and transport argon in its liquid state. However, it must be held at an astonishingly low -185.9°C. Fitting the pipes together and maintaining
Compressed non-asbestos gasket materials are subject to a natural aging process, like all elastomer-containing materials. This process depends on the kind of elastomer, its vulcanization system, and the storage conditions. Unfavorable storage conditions such as extreme temperatures, exposure to sunlight, low humidity, etc. can lead to a premature reduction of the material’s quality.
This blog will outline the conditions for proper storage of compressed non-asbestos gasket materials. These should be followed in order to achieve an optimum shelf life of 5 years...
This blog will discuss the differences between ASME flanges and AWWA flanges and the gaskets associated with each.
ASME flanges are the most widely used and specified flanges throughout industry in North America. Flange sizes ½” through 24” fall under ASME B16.5 and flange sizes 26” through 60” fall under ASME B16.47. Within ASME B16.47 there are series A and series B flanges, with the noticeable differences in most cases being the bolt size and/or bolt quantity.
So you spend hundreds or even thousands of dollars every year on sealing solutions, like gaskets. But did you know that the way you store your gaskets could affect the effectiveness or life span of your gaskets? In this blog, we offer some tips for gasket storage and shelf life which, if followed, can help ensure that your gaskets are always ready for service.
Rubber gaskets should always be stored in a cool location which is free from excessive humidity, direct sunlight, and the presence of chemical vapours or fumes. The storage location should ideally be indoors and free from exposure to the elements or inclement weather. If the storage guidelines given below are followed, rubber gaskets or gasketed components have the following expected shelf life:
Sunlight and strong artificial light can degrade some gasket materials. For this reason, rubber gaskets should be stored in cartons or opaque bags which prevent direct exposure to light.
Very moist or excessively dry conditions in a storage location should be avoided. Relative humidity levels below 75% are recommended for most rubber gaskets. Similarly, very low humidity levels which can cause some materials to dry out and become brittle should also be avoided.
