Avoid winder vibration with modern software and hardware tools

Some paper grades generate winder vibration. Modern tools help, such as 4-way hydraulic valves, stiffer drums with lower dynamic runout and automated controls.

Always putting the customer first

Global valve expert Neles is on an exciting journey. In 2020 the company spun out of Metso, in July this year Flowrox’s valve and pump businesses were acquired and further alterations could follow from a proposed merger with Valmet. These are just the latest steps in a success story that started back in 1956. Now celebrating its 65th anniversary, Neles has earned its status as a global supplier of choice thanks to the company’s unrelenting dedication to ensuring customers receive the very best solutions for their flow control applications.

Safe offshore production – part 1: challenges and role of automation

Oil and gas production involves great deal of risks that need to be addressed to perfection in order for production units to be safe for employees, surrounding population and vulnerable nature. This has been valid always, but even more today as easily extractable reserves are expended and oil is obtained from more challenging locations.

Experience matters in valve sizing and selection

All too often, valve sizing and selection tools are based on standard equations and rules of thumb shaped by performance data collected under laboratory conditions. While laboratory data may be considered extremely accurate, they are no substitute for real-world data collected under actual operating conditions over an extended period of time.

Managing valve wear in FCC slurry oil service

Fluid catalytic cracking (FCC) is an important upgrading process for converting heavy oil feedstock into products such as gasoline, light fuel oils, and olefin-rich gases at oil refineries. In this process, a hot catalyst from the regenerator flows in a fluidized state through the riser tube into the reactor. Do you want to enhance the wear protection of the critical flow control devices in the FCC unit? Read on and join my presentation in Valve World.

Managing wear in severe services

Wear in valves is surely an important concern for plant owners and operators. Eroded valve internals can have a long-term effect on the functioning and profitability of process facilities. Materials such as ceramic reinforced metals can be a good solution to increase component lifetimes in industries such as oil and gas, says Valmet’s Mr Jussi Hellman.

Reactive, preventive or predictive?

When it comes to maintenance, which is the right solution for a plant?

Taking a comprehensive maintenance approach to maximize PSA unit availability

A pressure swing adsorption (PSA) unit had become the source of a huge annual loss for several years in a French refinery. Constant failures of the unit systems led to unplanned shutdowns and loss of availability. Additionally, the refinery wanted to expand the unit to meet growing needs.

We make customer service up close and personal

Reliability is a core element of what we as a valves partner want to provide. Being close to our pulp and paper customers and having an in-depth understanding of their production processes is a prerequisite for good service. As a Resident engineer at a customer mill, I have a unique point of view in terms of customer proximity and understanding.
