Astm High Precision Polished Stainless Steel Instrument Tubing For Control Flow

In any industrial process control system, instrument tubing is essential to transport fluids and gases between various system components. Instrumentation tubing is used to control flow, measure process conditions, and analyze processes. This tubing is typically used with single and double ferrule fittings.

Stainless steel seamless precision tubes are used in instrumentation and hydraulic systems and are manufactured to ASTM A269 standard in standard sizes including 3/8 ", 1/4 ", 1/2 "and 3/4" outer diameter, 0.028 ", 0.035 ", 0.049 ", 0.065 "wall thickness. ASTM A269 instrument tubes have a smooth, polished annealed surface and strict diameter and wall thickness deviation requirements to reduce the risk of leakage when connecting the tubes with single or double-sleeve couplings.

Stainless steel instrument tubes are stainless steel duplex nickel tubes with mostly relatively thin walls. The diameter of most instrument tubes varies between 1.5 mm OD and 60 mm OD. 6 m of random length or up to 1000 m of coil, no weld.

Stainless steel instrument tubes are essential components in hydraulic and instrumentation systems that protect and cooperate with other components, equipment, or instruments to ensure the safe and trouble-free operation of oil and gas plants, petrochemical processing, power generation, and other critical industrial applications.

Stainless steel instrument pipes are available in a variety of sizes ranging from 0.125 inches to 2 inches in outer diameter and 0.012 inches to 0.25 inches in wall thickness. Pipe lengths can be straight or coiled, short lengths can be cut for structural purposes and can be bent when needed.

Conditions And Surfaces

Typically, hydraulic instrument pipes are annealed to conform to standard solution temperatures, followed by pickling to passivate the surface and remove burrs at the pipe end to insert fittings.

The surface of the pipe should be free of scale and clean. In some cases, polished annealing of seamless and welded pipes is required in order to achieve higher cleanliness and smooth surfaces.
