More contact area. More safety. Better sealing? Not necessarily. At the same bolt load, a wider gasket distributes the available force over a larger area. This reduces gasket stress. Yet this stress is exactly what allows the gasket to conform to the flange surface and close microscopic leakage paths. The physical principle: The mechanical

260 °C, 500 °C or even 1,000 °C? Temperature may seem to provide a clear answer when selecting a gasket. In practice, however, it is only one part of the decision. PTFE offers excellent resistance to many chemicals. Graphite withstands significantly higher temperatures and adapts well to irregularities in the flange surface. However, both materials

When a flange connection starts leaking, the first reaction is often simple: tighten the bolts again. It feels practical. It feels fast. And sometimes, the visible leak even disappears. But that does not mean the problem is solved. In many cases, retightening only hides the real cause of leakage. The connection may still be unevenly
Why Retightening Bolts Is Not the Real Solution Read More »
What TA Luft Requires – and Why It Matters TA Luft is one of Germany’s key environmental regulations for industrial plants. Wherever gases, vapors or other emission-relevant media are handled, operators must ensure that flange connections remain technically leak-tight. Achieving compliance involves more than selecting the right gasket. Pressure, temperature, bolt load and assembly quality

In one of the world’s most advanced research environments, absolute reliability is everything. The Deutsches Elektronen-Synchrotron (DESY) in Hamburg is a global leader in particle accelerator and photon science. At its facilities – including PETRA III, FLASH, and the European XFEL – scientists study the structure of matter at the atomic level. Their work pushes

Critical flange connections are found wherever media are transported under pressure, high temperatures or in safety-relevant environments. In industries such as chemical processing, energy and mechanical engineering, reliable sealing is essential for operational safety. One of the biggest challenges is knowing the actual force acting on the flange. In most cases, only the torque applied

What happens when modern equipment meets outdated infrastructure? For many plants, it means costly leaks, complicated workarounds, and frustrated employees. That was exactly the challenge facing a chemical production site in North Rhine-Westphalia until a collaboration between Covestro and Revoseal turned a long-standing problem into a breakthrough innovation. The Hidden Challenge in Everyday Operations

Steam Cracking: Where Everyday Plastics Begin At first glance, a plastic bottle, a smartphone display, or food packaging may seem far removed from heavy industry. But behind these everyday items lies a fascinating starting point: the steam cracker. In Europe alone, steam crackers have a total production capacity of around 23 million tons per year
