A Guide to Elastomer Technology in Mechanical Seals

Elastomers (or rubbers) are a ubiquitous family of materials whose use stretches across nearly the entire range of mechanical seal designs. From plant-sourced natural rubber, so named by John Priestly in 1770 for its utility in rubbing away pencil graphite, to petroleum-sourced synthetic rubber first developed around the turn of the 20th century, elastomers and their properties are familiar but should not be overlooked – especially when dealing with mechanical seals.

Rubber seals come in a variety of profiles – O-rings, cup gaskets, bellows diaphragms, sealing/wiper lips and many others. They are classified as either static or dynamic and create positive pressure against surfaces to eliminate or control the leakage of liquids and/or gases while preventing the entrance of external contaminants such as dust and dirt.

How to Investigate Compression Packing Failure Modes

In many respects, troubleshooting and failure analysis of packing materials is similar to the investigation of a crime scene. A good investigator knows how to gather clues from many different sources and put them together to understand what has happened. A good troubleshooter uses the same information gathering method, familiarizing themselves with the sealing materials, the process equipment and the systems where they are used.

The troubleshooter should seek information from the people who work with the equipment on a regular basis. Seal installers, maintenance personnel, operators, process engineers and others can all shed light on potential causes of failure.

The Importance of Using Thread Lubricants in Bolted Connections

Would you run your automobile engine without oil? Assembling a bolted joint without using a proper thread lubricant is a comparable scenario. Thread lubricants are often overlooked but can have a huge impact on the success of a bolted joint.

In any industrial plant, there can be thousands of bolted connections, primarily in the flanged connections throughout piping systems, on packed stuffing boxes on pumps and valves, and on heat exchanger covers, for example. All of these pieces of equipment are used to join components while maintaining a leak tight pressure boundary for a system.

The Gasket Division will hear an update on the SWG testing standard and will review trainings and webinars.

The Expansion Joint Division will hear updates from the Ducting technical committee and the Piping technical committee.

The Mechanical Seals Division will discuss KnowledgeBase content and functionality and industry standards, as well as progress on the Pump LCC.

FSA’s Technical Director will give a review of the highlights of his activities at the general session being held on Tuesday, October 23.

FSA Committees to Meet in Montreal on October 23, 2018

The FSA committees will meet at the Hotel William Gray in Montreal on October 23, 2018. Here’s what they will be talking about.

The Government Affairs Committee will keep FSA members informed on the latest information on Methane Rule in Canada and Mexico, as well as tariffs and the mechanical seal pipeline standard from API 682.

The Marketing Committee will discuss promotion of the FSA’s KnowledgeBase and the FSA’s participation in trade shows, social media activities, and partnering with the FSA’s media partners.

The Membership Committee will review the list of member prospects and the possibility of a new social meeting registration fee.

The Program and Locations Committee will discuss the schedule for 2019′s annual meeting, being held on October 21-25, 2019, at the Marriott City Center in Pittsburgh, PA. This meeting will be co-located with the Hydraulic Institute.

The Technical Coordinating Committee will review all of the division’s technical activities and the possibilities for cross-divisional activities in the coming year.

FSA Government Affairs Committee Keeping Members Updated

The FSA Government Affairs Committee is busy staying informed on activities in the White House and keeping FSA members informed. The latest update included the Joint US-EU Statement following President Juncker’s visit to the White House, released on July 25, 2018:

We met today in Washington, D.C. to launch a new phase in the relationship between the United States and the European Union – a phase of close friendship, of strong trade relations in which both of us will win, of working better together for global security and prosperity, and of fighting jointly against terrorism.

The United States and the European Union together count more than 830 million citizens and more than 50 percent of global GDP. If we team up, we can make our planet a better, more secure, and more prosperous place.

Already today, the United States and the European Union have a $1 trillion bilateral trade relationship – the largest economic relationship in the world. We want to further strengthen this trade relationship to the benefit of all American and European citizens.

This is why we agreed today, first of all, to work together toward zero tariffs, zero non-tariff barriers, and zero subsidies on non-auto industrial goods. We will also work to reduce barriers and increase trade in services, chemicals, pharmaceuticals, medical products, as well as soybeans.

This will open markets for farmers and workers, increase investment, and lead to greater prosperity in both the United States and the European Union. It will also make trade fairer and more reciprocal.

Secondly, we agreed today to strengthen our strategic cooperation with respect to energy. The European Union wants to import more liquefied natural gas (LNG) from the United States to diversify its energy supply.

Thirdly, we agreed today to launch a close dialogue on standards in order to ease trade, reduce bureaucratic obstacles, and slash costs.

Fourthly, we agreed today to join forces to protect American and European companies better from unfair global trade practices. We will therefore work closely together with like-minded partners to reform the WTO and to address unfair trading practices, including intellectual property theft, forced technology transfer, industrial subsidies, distortions created by state owned enterprises, and overcapacity.

We decided to set up immediately an Executive Working Group of our closest advisors to carry this joint agenda forward. In addition, it will identify short-term measures to facilitate commercial exchanges and assess existing tariff measures. While we are working on this, we will not go against the spirit of this agreement, unless either party terminates the negotiations.

We also want to resolve the steel and aluminum tariff issues and retaliatory tariffs.

FSA to Hold Annual Meeting in Montreal

The FSA will hold their Annual Meeting at the Hotel William Gray in Montreal, Quebec, on October 23-25, 2018. All committees and divisions will meet, and a general session with speakers will be held on Tuesday, October 23. If you are interested in FSA membership and would like to attend the meeting, please email info@fluidsealing.com.

The next Annual Meeting will be held in October 2019 in Pittsburgh, PA. This meeting will be co-located with the Hydraulic Institute. The exact dates are still TBD.

Compression Packing: A Look Beyond the Standard Stuffing Box

Stem packing is a familiar product. The most common type is braided compression packing. Braided packing is used in a wide range of applications. Depending on the service, construction materials can be as diverse as plants or animal derivatives, mineral fibers or synthetic plastics and even metal. The process of cutting rings from rope packing, inserting them into a stuffing box and torquing them to the right density is common, but it is not always the best choice. Another widely used manufacturing method is die-molding. It is the process of wrapping a material around a mandrel, placing it in a die and preforming it to make a seal. Using these and other manufacturing technologies, packing is found to work in applications as different as aerospace, heavy trucking and power generation. A review of some unusual applications demonstrates the versatility of compression packing as a selaing solution.
