Instrumentation Tubing

Metric and Imperial OD Tubing by Waverley Brownall is stocked. This seamless tubing comes in 316 stainless steel as standard to ASTM A-269.

This tube coincides with the duoloc single ferrule compression fittings.

Instrumentation Tubing

Stainless steel nominal bore pipe and tubing in 316.

Pipe is stocked in 6M randoms, but for ease of transport, tube can be cut in half (random length is between 5 and 7M.) Tube can be supplied in any length at no extra cost (minimum 1M.)

Sizing:

1/8″ – 2″ schedule 10 and 40 stocked.

Other sizes up to 12″ schedule 10, 40 and 80 are available to order.

Nominal Bore Pipe:

Only available in schedule 10, 40 and 80.

Tubing Material

Our standard tubing material is 316 stainless steel. Stainless steel is a popular choice of both tubing and fittings for its strength and durability. Our standard tubing will help to form long-lasting installations for such industries as LNG/natural gas. Our tubing is often ordered alongside fittings for brand new installation – or fittings can be purchased separately for whichever type of flow control your installation may require.

Stainless Steel 316

316 is an Austenitic chromium-nickel alloy that contains molybdenum.

Stainless steel 316 provides high resistance within areas of high temperature. It holds corrosion resistance against sulfuric, formic and tartaric type acids. For a full properties spec on stainless steel, please see data sheets that comply with UNS S31600 AND UNS S31603.

Tube Selection

Tubing should be solid drawn and fully annealed to ASTM A-269 or equivalent.

Maximum hardness: HRB 80 recommended

*If harder tube is used the HRB 90 should be the maximum allowed and specified.

Working Pressures

Please contact us on +44 01702 600014 for information on working pressure of tube with our fittings. Working pressures for metric and imperial sizing can be found in our Duoloc catalogue on page 10.

Tube Fittings And Valves

Tube fittings, pipe fittings and compression fittings are used for altering the flexibility of a tubing system. We offer a large range of UK manufactured tube fittings of single and double ferrule OD compression.

Both metric and imperial sizing are available to allow for easy selection when ordering tubing and fittings together.

Key:

Tubing within the grey-shaded area is not recommended with gas service.

It is recommended that tubing used within the teal-shaded area be pre-assembled in a pre-assembly tool prior to installation

Stainless Steel Tube Working Pressures

The working pressures in the following tables are for single ferrule tube fittings and connectors are based on tubing rated at 75,000 psi minimum UTS and allowable working stress of 20,000 psi as specified in ANSI B31.3 1987, for a temperature range of -29 degrees to + 30 degrees Celsius. Pressures for the above Metric Tube Sizes Chart is in bar. What is Pressure Bar?

Instrument Tubing Selection

A wide range of 316 stainless steel tubing
ASTM A-269 in both metric and imperial sizes
Cut to any length subject to a minimum of 1m
Imperial sizes for Tube OD include 1/16, 1/8, 1/4, 1/2 and more
Single ferrule compression fittings will work fine with most types of soft tubing as long as the tube wall thickness is 1mm or above
