Emili Sunyé is an Applications Engineer at EPIDOR and has more than 15 years of experience as a sealing expert. Specialized in failure analysis in industrial applications, he brings his technical knowledge to optimize the performance and reliability of the systems.
As is well known, three fundamental factors are involved in a flanged joint: the sealing gasket material itself, the hardware and the flanges. If the tightening torque of the hardware is insufficient, even if the flange faces are in perfect condition and the material is PTFE, the process fluid will leak through the flanged joint.
When the flanged joint is opened, the first thing to inspect will be the PTFE gasket, which will be in perfect condition if Gylon® restructured PTFE has been used. If the flange faces have the proper surface finish and...
At Epidor Seals and Rubber Technology we are aware of the critical aspects of our products depending on the needs of each application. A few months ago we published “The best guides in hydraulic or pneumatic cylinders”. In today's article, we are going to focus on hydraulic cylinders and their guide elements, whether rod or piston. The guides found in hydraulic cylinders are usually subjected to much higher loads than the guides for pneumatic cylinders, they receive loads that produce compressive and shear stresses, being...
As a continuation of the series of articles on valves published in our blog “Some valve sealing solutions”, “Certified O-rings for valves“ and “Elastomers resistant to aggressive fluids in valves”, this new article delves into another aspect of valves, in which we will explain which materials you should consider when choosing valve seats.
Examples of valve seats
Ball valve
For example, in a ball valve, the control element (ball) rests on the seat and rotates on the seat when the valve is opened or closed.
All industrial machines, regardless of their type, must be properly isolated. To isolate a machine means to protect all its components from the element that emits the vibration (motor, compressor, pump, etc.) and from other elements or machines that are located around it. To achieve this, the designer must take into account the location of the elements that will prevent the passage of mechanical waves to the rest of the equipment, thus avoiding possible damage to machines, people and products.
