Instrumentation Tube
Instrumentation tube is a high-precision seamless stainless steel tube used for connecting instruments, transmitters and control systems in process control applications. It offers tight tolerances, smooth internal surface and high pressure resistance, commonly applied in oil & gas, chemical, power and automation industries for impulse lines and analyzer tubing.
Instrumentation Tube
Precision cold-drawn tube with polished surface for ferrule-type instrument connections.
Product Overview
Instrumentation tube is cold-drawn in the soft state with a mechanically polished outer surface and a clean inner bore. Its tight tolerance and high precision make it fully compatible with ferrule-type (compression) fittings, ensuring leak-free connections in instrument and analyzer tubing runs.
