Fittings, plungers, valves and actuators operate under pressure, often in environments with fluids, humidity or chemical agents: a component out of tolerance or made from the wrong material can compromise the entire system.<\/p>\n<p>The pneumatic sector is one of the areas we operate in at MI.SO.: fittings, cylinders, valves and actuators are part of our daily production.<\/p>\n<p>&nbsp;<\/p>\n<h2>The choice of material is critical in the pneumatic industry for several reasons. Materials are chosen based on their resistance to wear, temperature, chemicals, and pressure. The correct materials ensure components function effectively and reliably under the demanding conditions often found in pneumatic systems. They also contribute to the longevity of the equipment, reducing maintenance costs and downtime.<\/h2>\n<p>I componenti pneumatici funzionano in <strong>conditions that test any material<\/strong>operating pressures that can exceed 10 bar, high-frequency repeated mechanical cycles, contact with compressed air, lubricants, and \u2013 in some sectors \u2013 aggressive chemical agents.<\/p>\n<p>The choice of material is therefore not just a matter of cost: it directly affects the <strong>Duration<\/strong> of the component, on the <strong>Estate<\/strong> of tolerances over time and on <strong>Regulatory compliance<\/strong> A standard brass fitting may be suitable for a general industrial plant, but not in an environment exposed to chemical vapours, where AISI 316 stainless steel or a technical plastic like PEEK is required instead.<\/p>\n<p>&nbsp;<\/p>\n<h2>The materials we use for pneumatic fittings<\/h2>\n<h3>Stainless steel<\/h3>\n<p>Stainless steel is the material of choice for pneumatic components operating in corrosive or regulated environments.<\/p>\n<ul>\n<li><a href=\"https:\/\/misominuterie.com\/en\/materials\/stainless-steel\/aisi-303\/\" target=\"_blank\" rel=\"noopener\"><strong>AISI 303<\/strong><\/a>easy to work with and with good mechanical resistance, it is the typical choice for fittings and screws in standard pneumatic systems.
