Stainless Steel Tubing

Stainless steel is widely used for chromatography and is suitable for a broad range of applications. Its high mechanical strength makes it especially useful to withstand the pressure of HPLC and Ultra-HPLC.

VICI Jour offers SS tubing in 2 grades: Standard and Premium Grade SS tubing

The tolerances of premium Grade SS tubing are +/- 0.001 ‘’ (+/- 0.0025mm) for both OD and ID.
Except for OD 1/32’’ and 360micron with IDs 100micron and less, for these tubing the tolerances are +/- 0.010mm.

The tolerances of Standard SS tubing are +/- 0.002’’ (+/- 0.050mm) for both OD and ID.

Stainless steel, Type 316

This is the standard tubing material for chromatography, suitable for a wide variety of applications. It is cold drawn seamless, not welded, with close tolerances held on both ID and OD. We neither recommend nor offer Type 304 stainless steel for analytical applications.
Austenitic stainless steels may be used for most chromatographic applications. Type 316 is most commonly used for HPLC because of its superior chloride ion resistance.

Stainless steel, Type 303

Recommended for GC use and general purpose connections, combining excellent machining characteristics with good resistance to corrosion and high temperature oxidation. Susceptible to attach by chlorides, iodides, and bromides.

Titanium

Although it is more difficult to machine than common alloys containing aluminum and vanadium, VICI uses Grade 2 pure titanium in order to avoid possible contamination of the sample stream with these metals. Good for organic and inorganic salts except aluminum and calcium chlorides, and all alkalis except boiling concentrated potassium hydroxide. Good with dilute, low temperature formic, lactic, sulfuric, hydrochloric, and phosphoric acids, but rapidly attacked by hydrofluoric acid. Good with dilute nitric acid at low temperatures; corrodes at high concentrations and temperatures. Can ignite with fuming nitric acid. Attacked by oxalic acid, concentrated phosphoric acid, hot trichloroacetic acid, and zinc chloride.

Pressure Rating for Premium Grade Bulk Stainless Steel Tubing

Pressure rating values shown in the table below are minimum values; rating varies with ID. The working pressure for stainless steel tubing is calculated from the burst pressure by dividing by 2.5. All pressures are calculated for room temperature.

OD bar psi
360 µm 679 9857
1/32" 400 5800
1/16" 365 5300
1/8" 315 4600

 

Pressure Rating for Standard Grade Bulk Stainless Steel Tubing

Pressure rating values shown in the table below are minimum values; rating varies with ID.
