In the past, threaded or flanged connections were the standard choice for liquid level instrumentation in most industrial applications. However, when we started working on instrumentation for food industry projects, we noticed that many customers had switched to a different type of interface—the TC connection. Initially, the change was puzzling. But after observing the cleaning […]
Stainless steel, known for its excellent overall performance and aesthetic surface characteristics, is widely used in various industries—including in level instruments and fluid transport systems. Among its many forms, stainless steel pipes are the most commonly applied components. These pipes can be broadly categorized into two types: seamless stainless steel pipes and welded stainless steel
