ASTM A588 Corten Pipe & Tube Supplier

Large-Diameter Corten B Pipes & Columns Rolled from ASTM A588 Plate

Dinesh Tube India supplies ASTM A588 Corten pipes and tubes from Mumbai to chimney and duct fabricators, bridge and structural contractors, architects and landscape designers. These are rolled and welded from ASTM A588 Grade A plate (Corten B), mainly in larger diameters and heavier walls than standard tube mills make, such as stacks, ducts, columns, bollards and architectural cylinders.

Important: ASTM A588 is a specification for plates, shapes and bars, not for tubes. An "A588 tube" is fabricated from A588 plate, and the mill certificate covers the plate. For standard-size structural round, square and rectangular tubes certified as tube, order ASTM A847. For all Corten tube grades, see Corten steel pipes and tubes.

What Is an ASTM A588 Tube?

ASTM A588 / A588M covers high-strength low-alloy structural steel with improved atmospheric corrosion resistance and a minimum yield of 345 MPa (50 ksi) up to 100 mm thickness. It is the standard US grade behind Corten B. When a drawing calls for "A588 pipe" or "A588 tube", it usually means a cylinder rolled from A588 plate and welded. This is the usual route for diameters and walls beyond the range of standard hollow sections, and for structures where tubes must weather to the same colour as A588 plate members.

Like all weathering steels, A588 forms a protective patina in the open air but is not stainless steel. It is not intended for pressure piping, marine immersion, buried service or chemical process duty.

How A588 Corten Pipes Are Made

Plate: ASTM A588 Grade A plate with EN 10204 3.1 certificate, cut to developed length
Rolling: plate rolled to the required diameter on plate-bending rolls (longitudinal seam); spiral forming for long continuous lengths
Welding: seam welded with weathering-grade consumables so the weld weathers like the pipe
Ends: plain or bevelled; flanges, base plates or caps as per drawing
Inspection: dimensions, ovality and weld inspection to the agreed drawing or code

Chimney, bridge and architectural uses of A588 Corten pipes

Seal or drain closed sections so water cannot collect inside. For matching flat material, see Corten steel plates and S355J2W plates.

ASTM A588 Corten Tubes: FAQs

Is there an ASTM A588 tube or pipe specification?

No. ASTM A588 covers plates, shapes and bars. "A588 tubes" are rolled and welded from A588 plate, and the mill certificate covers the plate. Standard-size structural tubes in weathering steel are certified to ASTM A847 instead.

What is the difference between A588 pipe and A847 tube?

A588 pipe is fabricated from A588 plate, usually in large diameters and heavy walls for stacks, ducts and columns. A847 is a tube specification for cold-formed weathering structural tubing in standard round, square and rectangular sizes, with properties tested on the finished tube.

What sizes of A588 Corten pipe can be made?

Rolled and welded A588 pipes are typically made from about 219 mm up to around 2000 mm outside diameter, with walls of about 6 to 40 mm, to the customer's drawing. Send the diameter, wall, length and end details to confirm.

Can A588 Corten pipe be used for pressure or process piping?

No. A588 is a structural weathering steel, not a pressure piping material. Use pressure pipe grades such as ASTM A106 or A333 for steam, oil and gas or process lines, and stainless steel for corrosive fluids.

What welding consumables are used for A588 pipes?

Seams are welded with weathering-grade consumables containing nickel and copper, so the weld develops the same patina and corrosion resistance as the plate. The welding procedure and preheat depend on wall thickness.

Why choose A588 for chimneys and stacks?

Exposed stacks and ducts can be left unpainted because A588 forms a protective patina outdoors. Where flue gas condenses inside, acid dew-point corrosion must still be considered in the design; low-alloy grades do not make a stack immune to condensate attack.

Do A588 Corten pipes rust inside?

They can if water collects. Cap and seal closed sections, or drill drain holes at low points, so the inside does not stay wet.

Which certificates come with A588 Corten pipes?

We supply the EN 10204 3.1 mill test certificate for the A588 plate, plus dimensional and weld inspection records for the fabricated pipe. Third-party inspection can be arranged on request.
