ASTM A269 TP304 9.53X0.89 mm Coiled Tubing

ASTM A269 TP304 9.53X0.89 mm Coiled Tubing

Stainless steel tubing in coils and on spools used for control lines, chemical injection lines, umbilicals as well as hydraulic and instrumentation systems.

Used for a variety of circulation systems for different gases and fluids, coil tubes provide the ability for long length tube installations 

without the need for joining fittings. CNMAX produce seamless coil tubes and can provide them in long mill lengths 

or cut-to-length in sections as short as fifty feet. These products have industry applicability for petrochemical, oil production heat tracing, 

geothermal and flow measurement applications.

CNMAX offers stainless steel coiled tubing in sizes from 1/4 to 1/2 in. and wall thickness from 0.035 to 0.049 in.  

CNMAX stainless steel coiled tubing is available in lengths up to 2300 feet, which is up to 30% long than traditional offerings.  

In addition, CNMAX offers less than reel quantities of coiled tubing.  Stainless steel tube straighteners make coiled tubing installation faster and easier

Select stainless steel coiled tubing for your applications.
