New FKM material specifically to meet the demands of the oil and gas industry

With the newly developed FKM compound Vi 900, the seal manufacturer C. Otto Gehrckens presents a high-performance product innovation for use in the petrochemical industry. The material has proved its suitability as a dependable elastomer seal even under the most demanding conditions, complying with NORSOK test standard M-710 and also passing the hardness test with the best possible rating of 4x ‘0000’, without showing any damage whatsoever. Vi 900 is therefore ideally suited for use in production sectors which, as a result of the danger of explosive decompression, impose especially high demands on the seals used.

The special feature of this new product development is its outstanding stability under low temperatures. With a TR-10 value of -40°C, Vi 900 is suitable for the coldest applications, right down to -50°C and, as well as complying with the NORSOK standard, it therefore also complies with American standards API 6A and 6D for oil and gas installations. According to the manufacturer, combined with an extraordinarily good cold compression set this high-performance material sets new standards in relation to AED (anti-explosive decompression) and RGD (rapid gas decompression) seal materials.

A further plus point for this new FKM compound is its excellent resistance to a wide range of specific media and chemicals, from mineral oils to aliphatic, aromatic or even chlorinated hydrocarbons and also to acids in various concentrations and weak alkalis. And as the material is also characterized by very low gas permeability, a wide range of applications is possible. Vi 900 is used as a seal material in valves, ball cocks, pig traps or slider valves in production areas where the very highest levels of reliability and the best possible quality with respect to explosive decompression are required, above all in the petrochemical industry, in compressor construction and also in compressed air preparation. This new material is available with immediate effect.

New, self-sealing GEMÜ connection principle for modular valve solutions

Faulty O-rings can cause direct and indirect consequential costs through machine downtimes, recalls or environmental damage. In the presence of chemicals and additives as well as of elevated temperatures, these elastomer seals reach their limits of wear soon. Therefore, GEMÜ has developed an innovative sealing method without O-ring for its iComLine product range. Two contours synchronized with each other fit with precision and thus ensure lasting, reliable sealing. The developed sealing principle without O-rings thus not only saves the additional cost for the elastomer seals but also increases the service life of the modular valve solutions considerably. The new sealing method makes almost deadleg-free sealing possible. In addition, the optimized installation of accessory parts and additional connections to the various multi-port valve blocks support the modular and consequently flexible construction of the multi-functional iComLine block solutions.

Depending on the requirements, stainless-steel screws or a thread directly machined into the GEMÜ PC50 multi-port valve block ensure the joint and compression of the two seal contours. The innovative joining principle is available for all GEMÜ PC50 iComLine multi-port valve blocks made of PTFE material. It is qualified for an operating pressure up to 6 bar and can be used at media temperatures from -10 to +150 °C.

The GEMÜ PC50 iComLine block solutions with O-ring-free sealing are available now in nominal sizes 3/8“ and 1/2“. Further nominal sizes can be qualified on request and provided in a customised manner.

Though adhesives are a crucial part of the packaging industry, manufacturers need to ensure their work is environmentally friendly. artimelt can offer their product partners across the value chain a range of products.

What role do adhesives play in packaging, with particular regard to product labelling?

artimelt: Adhesives play a vital part in almost every form of packaging. They are needed to laminate filmic materials to provide the desired functions of packaging materials, or to encase printing layers. Adhesives are used to erect boxes from cardboard sheets.

When it comes to packaging decoration, pressure-sensitive adhesives enable various types of labels to be applied easily and efficiently. Adhesives are essential in fulfilling packaging’s main functions: the containment, protection, identification, presentation and promotion of goods.

What is artimelt’s relationship with
packaging converters?

artimelt develops, manufactures and markets hot melt adhesives. It produces pressure-sensitive adhesives that are used for self-adhesive or peel-and-stick labels.

artimelt works with label laminate producers and printers to select the right adhesive for them. At the same time, the compliance requirements for food standards have intensified in recent years.

The company therefore works closely with its customers and their customers – to properly assess and understand adhesive behaviour to ensure safety.

It develops highly specialised closure systems that include tamper-indication features; for example, for duty-free or crime-scene-investigation bags.

artimelt also develops heat-seal coatings that are used to close pouches for medical devices. The adhesive in this particular application is adapted to the fibrous substrate, so it doesn’t tear upon opening.

What is the importance of bio-based products – and degradability – in packaging?

Almost all packaging becomes obsolete once the product has been used. The industry has therefore worked hard to reduce the amount of material it uses, to become more efficient, and to promote reuse or recycling. Bio-based and/ or degradable packaging components have also entered the market. artimelt believes that a holistic approach is necessary to make packaging more sustainable.

Although adhesives have an important function in packaging, they are typically invisible, and often forgotten. This means that a clear understanding of packaging, its construction, and end-of-life scenarios are the basis for sustainable projects. artimelt is keen to discuss these topics with brand-owners.

What kind of technology does artimelt use to help make packaging more sustainable?

Hot melt adhesives are an environmentally friendly adhesive technology. They don’t employ solvents or other carrier liquids that need to be transported and dried off after application. artimelt can further support the sustainability activities of the packaging industry in various areas. For example, it creates adhesives with a bio-based content of up to 70%.

It also offers adhesives with tailored properties to enable the removability of labels, and adhesives that are compatible with recycling processes. Some of artimelt’s adhesives are particularly suitable for linerless labels, a development welcomed by its customers. Linerless labels are cost-effective, environmentally friendly and sustainable.

In general, why should customers choose artimelt over its competition in the packaging industry?

artimelt has over 35 years’ experience in the development, production and application of hot melt adhesives. Its staff is personally committed to learning what their customers need, and its ‘experience lab’ provides an ideal testing environment for the exchange of knowledge, the conduction of coating trials and the preparation of prototype samples.

Schneider-Kreuznach präsentiert True-Net Diffusionsfilter

Schneider-Kreuznach, bekannt für seine erstklassigen Objektive und Filter, stellt den True-Net Diffusionsfilter vor. Dem Entwicklerteam ist es gelungen, den alten „Seidenstrumpf-Look” zu reproduzieren. Zum ersten Mal kann man diesen speziellen Look viel einfacher erzielen als mit dem jahrzehntealten Kameramann-Trick, bei dem ein Seidenstrumpf über die Linse gezogen wird. Die neuen True-Net Filter gibt es in drei verschiedenen Versionen, die einfach zu montieren sind und immer gleichbleibende Ergebnisse liefern. Nachdem er die Filter für sein kommendes Projekt getestet hatte, erklärte Kameramann George Mooradian, ASC: „Ahhhhh, ich hielt den ersten True-Net Filter vor mein Auge und es brachte so viel Schönheit und Romantik hervor, dass ich mich wie in einem europäischen Film fühlte. Es ist ein wunderschönes Vintage-Gefühl, das den ursprünglichen, sauberen, sterilen Look der modernen Kameras und Objektive auslöscht.”  

Schneider-Kreuznach hat eine Technik entwickelt, die es ermöglicht, den Stoff – der seit den Fünfzigerjahren auf den gleichen Strickmaschinen hergestellt wird – in das markentypische, kristallklare optische Glas zu integrieren. Wie die anderen professionellen Cine-Filter des Unternehmens sind die True-Net Diffusionsfilter laminiert und mit dem einzigartigen Schneider-Kreuznach Edge Seal vor Kantenabplatzungen geschützt. Dadurch werden zudem Kantenreflexionen und Kanteneinstrahlungen reduziert.

Die Serie umfasst insgesamt sieben verschiedene Filter. True-Net Blacks gibt es in drei Stärken, von dezent bis ausgeprägt, um ein einmaliges Old-Hollywood-Feeling zu erzeugen: romantisch, elegant oder verführerisch. True-Net Beige, erhältlich in zwei Stärken, kann den warmen und verträumten Look der 1960er und 70er erzeugen. Die beiden True-Net Gray Filter zeichnen sich durch ein gedämpftes, zurückgenommenes Bild aus, das einen angenehmen Kontrast beibehält. 

Die True-Net Filterserie ist derzeit in der Größe 4×5,65 erhältlich. Der unverbindliche Verkaufspreis pro Filter beträgt 365,- €. Andere Größen können auf Bestellung angefertigt werden.

Reliable even at high operating pressures

The GEMÜ 790 ball valve series stands out thanks to its compact yet robust design. At the same time, it is suitable for use up to a pressure rating of PN125.

Ball valves can be used in a wide variety of applications in industrial processes, and in water supply and water treatment systems in particular. One of the most efficient filtration procedures in water treatment is reverse osmosis. During this procedure, the unclean water is pressed through a semi-permeable diaphragm at high pressure. This filters unwanted substances out of the water. The differing electrolyte loads of the raw water fundamentally determine the treatment process with regard to the water quality that must be achieved. The higher the concentration of electrolytes, the higher the pressure must be in the system. Thus, the operating pressure range for ball valves in industrial waste water treatment, for example, is 60 to 70 bar; by contrast, it is between 60 to 80 bar for sea water. A ball valve which is installed in the raw water supply or clean water drain outlet must be able to sustain these demanding operating parameters in order to ensure a safe process sequence.

High operational safety due to low maintenance engineering

The highly polished and precisely manufactured GEMÜ 790 series ball fits snugly and air-tightly into the internal seal contour. A discharge slit in the seal ensures pressure relief in the valve flow. This not only reduces the seat wear but also lowers the actuating torque required to rotate the ball. This enables both cost-effective and energy-efficient system operation. The additional pressure relief hole in the ball enables pressure compensation, preventing a potential failure due to an internal build-up of pressure. Blow-out protection in the shaft ensures maximum operational safety. The antistatic device provides a permanently conductive connection between the ball and the shaft. A tongue-and-groove-style connection between the shaft and the valve body enables full earthing of the ball valve during installation in the system. This also ensures that it is safe for use in ATEX areas.

The stainless steel ball valves of the GEMÜ 790 series are designed to enable quick and easy servicing of internal wearing parts at all times. The generous valve neck extension has a top flange in accordance with EN ISO 5211. This standardized interface enables the user to fit the ball valve with various different actuators. The solid design of the body with an additional enclosed body seal enables use at pressures up to 137 bar as well as in vacuum applications. Depending on customer requirements, the ball valves are available with full or with reduced through flow.

Diaphragm seal systems with process transmitters: Replacement service optimises the benefit

Operators of diaphragm seal systems with mounted process transmitters can now take advantage of a replacement service. WIKA has put together a service package with which the long-term benefit and the overall costs of such a measuring assembly can be optimised.

Diaphragm seal systems often operate under extreme conditions. In the event of a failure of the system, however, in many cases it is enough to replace only the mounted diaphragm seal and to continue using the process transmitter. As part of the replacement service, WIKA takes the measuring system apart, checks and certifies the functionality of the process transmitter and replaces the mounted diaphragm seal with an equivalent one. Then a calibration of the new diaphragm seal system is made. If necessary, the mounting and the system fill fluid will be optimised and also new material test certificates issued.

With the replacement service, the process transmitter can be fully utilised over its entire service life. Preventive exchange of the diaphragm seal at planned shut-downs further reduces plant downtime. In order to offer this new service worldwide, and as close to customers as possible, WIKA will install service centres in the respective subsidiaries.
