Process monitoring instrumentation is used in the majority of main sectors, including those that produce aerospace, defense, power, petrochemicals, alternative fuels, shipbuilding, and medical equipment.
PM&C instrumentation fittings include pressure gauges, fittings, and tubing in addition to flow meters, strain gauges, and level gauges. They are used to calibrate the system to transmit, monitor, and control flow, pressure, and temperature.
The proper operation of the plant or product group depends on the instrumentation fitting components. Fittings, valves, and tubing serve as the veins and arteries of the instrumentation system.
Four types of instrumentation tube fitting
- Fittings for compression
The most organized and convenient fittings to use are compression fittings. This design employs a series of holds on the tube. The ferrule secures itself to the surface of the tube by coining (compressing) it. Not just over-buttweld fittings, but all fittings, perform better than compression fittings in terms of resistance to vibration. This form of fitting does not demand the use of any specific equipment. Slide the tube into the stop relation with caution, then tighten it by giving it a boxer twist to the desired torque. Due to their ease of use, compression fittings are frequently the least valuable overall convention.
- Fittings for cones and threads
Though they are occasionally used in high-pressure installations, cone and thread connectors are most frequently used at pressures up to 15,000 PSI. The connection between the tube and fitting is secure and tight since the tube has a hard edge and is screwless. To ensure a tight seal, the tubing must be attached snugly against the junction after the tube sides have been precisely formed with a smooth polished shine. Everything is often completed on the job, which significantly increases the assembly time and cost of C&T fittings. C&T fittings can be removed and rebuilt for maintenance just like compression fittings.
- Fittings for Butt Weld
The convention that offers the best oscillation safety is a butt weld fitting. Since the metals are firmly fused together, a well-formed butt weld has the maximum tolerance to noise and wear. On the other side, a butt weld fitting connection has substantial disadvantages, such as cost. Due to the cost of welding supplies, the need for a skilled welder, and the added labor hours, a butt weld connection is the most expensive of the three main types of instrumentation fitting components.
- Pneumatic Fittings with a Push-To-Connect System
Push-to-connect fittings join tubing by using an outside push switch and an interior collet. Polymer, nickel-plated metal, two layers of plastic, and composite materials can all be found in the construction of these fittings. For all compressor applications, leak-free and secure couplings are guaranteed with push-to-connect air connectors for elastomeric or nylon tubing. By repeatedly pressing the tube into the fitting, push-to-connect pneumatic fittings allow for rapid connections without the need for tools, and disconnections are just as easy.
