36 years and counting - no 2 days are ever alike at the global service center

I was asked to offer our readers a glimpse into the typical working day at Neles’ Global Service Center in Helsinki, Finland. To be absolutely honest with you, there is no such thing. Each day brings along new interesting challenges from all over the world, and our dedicated service team welcomes those challenges with open arms.

Cost effective and optimum valve selection for process plants

Process uptime, safety and productivity are topics that always count when speaking about industrial processes and process plants. Correctly selected process valves are essential to achieve the set uptime, safety and productivity targets and also help minimize the maintenance costs and waste of energy and raw materials.

Diamonds are created in high pressure – where reliability and trustworthiness count even more

With increasingly stringent requirements being placed on challenging industrial processes, customers are demanding ever more reliable valve solutions to make their operations safe, environmentally friendly and future-proof for new regulations. These requirements set high-level expectations on a long servicing interval for valves and minimized process downtime. They also lead to high-yield processes for customers.

Reliable control valves – foundation for process performance and uptime

When considering control performance in a modern process plant, it is easy to get confused by the complexity of it all. The control system is usually the part plant owners concentrate on most. However, one should not forget that the last control element – the control valve – sets the baseline for accurate control.

Control valves for feedstock, dilution steam and fuel to furnaces

This is Part 2 of our series of three posts on valve selection for ethylene cracking. An ethylene steam cracker can accept a variety of feedstock.

Flow control solutions for ethylene cracker furnaces

This is Part 1 of our series of three posts on valve selection for ethylene cracking. Ethylene is a basic building block in the chemical industry, and is the link between chemical companies and petroleum refiners. An ethylene plant, also well known as a steam cracker, is often and correctly called an olefin plant because of the fact that the end products are primarily olefins, mainly ethylene, propylene and butadiene.
