Ultrasonic Flow Meter Applications
Ultrasonic flow meters are used to measure hydrocarbon gases in applications which require wide range (turn-down ratio), very high or low flow, low restriction, high accuracy or any combination of these from low pressure to super-high pressure.
User report - Close Coupled Installation Concepts
The Indian Oil Corporation Ltd. relies on Close Coupled Installations in its refinery in Mathura, India. The company has equipped more than 400 measuring points with so-called installation hardware - which has been extremely successful: The installation effort could be reduced from 16 hours per valve to just one hour. The planning and layout of the plant was much easier, and the measuring devices have worked accurately and reliably since installation.
Metallic - practical - tight
Our customers are often faced with the challenge of determining exactly the right valve/manifold application for extreme operating conditions. For process plants I can recommend the use of metal seated ball valves if abrasive products, high temperatures and pressures are present. Extreme operating conditions with temperatures up to 450 °C and pressures up to 420 bar require a special sealing technology for ball valves. Standard soft seated ball valves simply aren't ready for this kind of requirements. Their plastic seals would fail.
Social project: Holiday children as hotel builders
Actually fittings are manufactured at AS-Schneider. However, children on holiday in Nordheim embarked on a hotel construction project under the direction of our apprentices: with an insect hotel craft day as a social project.
Does the seal ring fit? Avoid bad surprises.
Direct mount manifolds for pressure and differential pressure transmitters are normally protected against excess warming from hot process media through correspondingly long impulse lines. Nevertheless, many users have requested that the manifolds and their flange connection to the transmitter also easily withstand higher temperatures. Therefore the seal rings have to be made of graphite. Thus they can be readily used up to 550 degrees Celsius – significantly more than required by the standards.
Small, but powerful: Low torque for a smooth operation
During my last 12 years in the instrumentation business I have been asked many times at which pressure a manifold can still be operated. As well as, what is the difference between the following two non-rotating stem designs: Stem to needle interface above the packing and below the packing.
There is no reason to specify DIN 19213 instead of IEC 61518
IEC 61518 is the global standard for Manifold-to-Transmitter Flange Connections. IEC 61518 is based on the German standard DIN 19213. So, basically DIN 19213 is not anymore used with the exception of revision 1980. But there is also a technical reason why DIN 19213 should not be used anymore.
Industry 4.0 at medium-sized companies
What challenges and opportunities does Industry 4.0 pose for a medium-sized company in the industrial valve industry? Plant manager Rolf Baumann from AS-Schneider gives insights.
Pressures of several hundred bar, temperatures up to 600 degrees Celsius: Industrial valves, such as those used in power plants, the oil and gas industry or in chemical process systems, work under the most arduous conditions. In such cases, safety is the most important aspect. Not only the enormous pressure, but also the often toxic or aggressive process media can quickly become a hazard for people and the environment. Valves must not only be perfectly matched to the particular application but also provide protection against an unauthorized access or accidental operation of the valve.
Maximum safety in every application
Strict requirements are imposed on process systems in the chemical industry. This also means that gases and liquids must not be allowed to escape from pipes or valves. A critical point from which chemicals can easily escape is the measuring devices which are installed in production systems for process monitoring.
How can you profit from Close Coupled Installations?
During my career as an instrumentation specialist, I have noticed that in certain industries, especially in the chemical industry, there is a trend towards Close Coupled Installation Concepts. But what is actually behind the Close Coupled Installation Concepts and how can you benefit from it?
How do I know which product is for which application?
Whether in the chemical industry, power plant construction or in the oil and gas industry: Planning, design and operation of process systems are extremely complex and require a great deal of expertise. For example, in the selection and procurement of suitable valves. Because here, not only the economy plays an important role, but above all the safety. Regulatory requirements must also be complied with the installation location and process medium.
Tim-Frederik Kohler, CSO at AS-Schneider, speaks on the advantages of an intensive cooperation in form of customized in-house trainings.
Corporate Social Responsibility in medium-sized companies
Behind Corporate Social Responsibility (CSR) lies a broad field of activity in voluntary social, ecological and economic components. Due to the many design possibilities, medium-sized companies have to be careful when developing a suitable CSR strategy. Otherwise, the companies will take over. Ute Hellger (Human Resource Manager at AS-Schneider) recommend adapting CSR measures to company size. The contribution of a medium-sized company must remain viable and affordable. Often, the responsibility for CSR is shared in different departments and there is no dedicated person for it.
Innovations and their impact on industrial valves
Innovations are one of the most important growth drivers and make a significant contribution to the company's success. For sustainable successful innovation results, a culture of innovation must be created. That should be based on the cultural and organizational skills.
But how can the innovation culture of a company be developed and permanently anchored in the organization? We asked Markus Häffner, Head of Construction & Development at the AS-Schneider Group.
Focus on Safety & Environment in the Valve Business
The equipment sold into the oil and gas industry must meet the highest standards when it comes to safety and environmental issues and industrial valves are no exception. Consistently over the years customers in this industry have made it clear that safety and the environment were on the top of their lists when evaluating products. The negative consequences for not paying attention to these areas can be devastating to an oil and gas company.
To keep the environment clean
Flush rings help to properly dispose of residual gas and liquid during maintenance and repair of measuring arrangements. In addition, they are suitable for avoiding blockages in the process connection piece. They are used, for example, in the chemical industry. Here strict requirements apply to the process plants: Safety and environmental protection must be guaranteed at all times, because not all processed substances are harmless to humans and nature. This also means that gases or liquids must not escape from the systems - neither during operation nor during maintenance. Flush rings are important helpers here.
With the company health management strengthen the employees & the company
In addition to a good business idea, a successful company needs competent executives and high-performance employees. But performance alone is far from enough to boost productivity in a business. This works only with healthy and highly motivated employees. But the health of the workforce is not self-evident. We talked to Ute Hellger, Human Resources Manager at the AS-Schneider Group, about what occupational health management means and what added value it brings to employees and the company.
