Contents:

At the start of the Stainless Steel Welded Tube manufacturing process so called slabs or billets are cast in a steel mill. Dependent on the external dimensions and wall thickness there are different methods of producing welded tubes: Electric Resistance Welding (ERW), Fusion Welding (EFW) and Double Submerged Arc Welding (DSAW). In the ERW and EFW manufacturing process welded tube are formed by hot or cold rolling plate and welding the seam. In order to keep the outside (O.D.) surface of a welded tube smooth and uniform a cutting tool called scarfing blade is used to remove the weld flash. Scarfing from the inside (I.D.) welded flash is also possible. With a heat treating at the end of the manufacturing process the weld zone of the steel tube can be made less visible. Due to the weld seam lower operating pressures are stated in accordance with ASME compared to Welded Tube. In general welded tubes possess tighter dimensional tolerances than Welded tubes and are less costly if produced in same quantities.

SS ERW Tube means Electric Resistance Welded Tube. Usully for for high diameter. (cheapest process avaiable) ERW Tube means Electric Resistance Welded Tube. ERW steel tubes are used in various engineering purposes, fencing, scaffolding, line tubes etc. ERW steel tubes are available in various qualities, wall thicknesses, and diameters of the finished tube.

Welded Tube is manufactured in round, square and rectangular sections in a variety of wall thicknesses. It is usually manufactured by the processes of longitudinal welding, hot and cold drawing (Welded) or spiral welding.

Finishes or appearance range from unpolished to highly polished. Unpolished has a 2B mill finish, standard polished is a finely grit polished finish and there is a finer buffed finish giving close to mirror appearance. Finishes are selected to suit application and aesthetic appeal.

Stainless steel Welded Tube can be joined by welding, which facilitates rigidity in construction, or by the use of mechanical fittings which enables dismantling for hygienic cleaning.

Welded Tube is usually annealed if extensive forming and bending is required, such as for bending or expanding. The tubular products system incorporates a comprehensive range of stainless steel fittings in the form of elbows, tees, reducers and flanges in various sizes, wall thickness, grades and finishes to suit Welded Tube dimensions and tolerances.


As-welded (AW) tube

Decorative and Structural tube

This tubing is produced direct off the continuous tube welding mill, using cold rolled stainless steel strip made to ASTM standards, with tube produced to commercial limits of straightness in standard or specific customer lengths. AW tube has a higher yield point than annealed tube and is generally used for decorative applications or in mildly corrosive conditions. It is not suitable for applications requiring significant flaring, expanding or bending.

Manufacturing specification: ASTM A554.

 

Food quality Stainless Steel Welded Tube

This tube at the point of manufacture goes through a process where the internal weld bead is rolled. The result is an improved internal finish along the weld, reducing the chance of a crevice where liquid or food product may be trapped. This assists with 'clean in place' (CIP) environment food and beverage process lines or other applications such as the pharmaceutical industry.

Manufacturing specification: ASTM 1528.

 

As-welded annealed (AWA) tube

This tube is produced by the same process as AW tube but is annealed to relieve stresses and improve ductility. Bright annealing is carried out in a controlled-atmosphere furnace, so that no oxide or scale is formed on the surface.

Annealing both increases the corrosion resistance and softens the tube which allows severe manipulation such as bending, expanding and forming.

Manufacturing specification: ASTM A269.

 

Cold worked annealed (CWA) tube

This tube is typically destined for heat exchanger applications and is produced in a similar way to AWA product except that the internal bead is rolled flush with the inside tube surface prior to annealing.

Manufacturing specification: ASTM A249M.

 

Cold drawn welded (CDW) and cold drawn welded annealed (CDWA) tube

 

The tube is produced by drawing through a hardened steel or tungsten carbide die, at room temperature. The purpose of cold drawing is to reduce the OD or wall or both, to produce a smooth surface finish and to break up the weld structure, which results in recrystallisation when annealed.

Through cold drawing tube in the AW and AWA conditions, fine dimensional tolerances are achieved, with excellent uniformity of wall thickness and concentricity, grain structure and hardness.

Manufacturing specification: ASTM A249M.

Spiral welded tube

This tube is produced by the helical forming and automatic welding of a continuous strip of stainless steel.

Typical applications include water and pulp in paper mills, product and effluent lines in chemical processing, water lines for brewing, dust fume extraction, furnace and boiler flues, stormwater in high-rise applications and ventilation ducts and condensation lines for air conditioning.

Manufacturing specification: generally to ASTM A778, except for mechanical properties.

Manufacturing Stainless Steel Welded Tube

There are three main methods of manufacturing tubing that lend their names to tubing classifications. 

Welded
Welded steel Welded Tubes are produced through extrusion. Extruded Welded Tubes can be formed in a hot or cold process. Long sections of steel bar are forced through a die that blocks out the intended shape of the Welded Tube.

Drawn-over-mandrel (DOM)

A mandrel is a small piece of metal inserted into the Welded Tube to define a shape. It gives the Welded Tube extra support to prevent unwanted wrinkling during drawing. The Welded Tube is passed through a die that has a smaller diameter than the current Welded Tube size. As the Welded Tube is drawn, it shrinks to match the size of the die’s diameter. This process allows for tight tolerances and specifications. 

Each of these manufacturing processes allows manufacturers the ability to form varying Welded Tube shapes and sizes. Welded Tubes are not always cylindrical, and can be made in triangle, square or other polygonal shapes. Steel Welded Tubes destined for certain applications require extra processes as well. Applications involving hydrogen must be factory pre-cleaned or certified as instrument grade due to hydrogen’s reactive characteristics that can cause metal embrittlement or even explosions. 

Generally, a steel Welded Tube manufacturing process is chosen for its interaction with the type of steel to be used. Certain types of steel react poorly to heat because of carbon content, so they can’t be easily welded. Steel types also play a role in decisions regarding use in volatile applications.

Stainless Steel Welded Tube Applications

Stainless steel™s resistance to corrosion and staining, low maintenance, relatively low cost, and familiar lustre make it an ideal material for many applications. There are over 150 grades of stainless steel, of which fifteen are most commonly used. The alloy is milled into coils, sheets, plates, bars, wire, and tubing to be used in cookware, cutlery, hardware, surgical instruments, major appliances, industrial equipment (for example, in sugar refineries) and as an automotive and aerospace structural alloy and construction material in large buildings. Storage tanks and tankers used to transport orange juice and other food are often made of stainless steel, due to its corrosion resistance and antibacterial properties. This also influences its use in commercial kitchens and food processing plants, as it can be steam-cleaned and sterilized and does not need paint or other surface finishes.

Stainless steel is used for jewellery and watches with 316L being the type commonly used for such applications. It can be re-finished by any jeweler and will not oxidize or turn black.

Some firearms incorporate stainless steel components as an alternative to blued or parkerized steel. Some handgun models, such as the Smith & Wesson Model 60 and the Colt M1911 pistol, can be made entirely from stainless steel. This gives a high-luster finish similar in appearance to nickel plating. Unlike plating, the finish is not subject to flaking, peeling, wear-off due to rubbing (as when repeatedly removed from a holster), or rust when scratched. Some automotive manufacturers use stainless steel as decorative highlights in their vehicles.


Stainless Steel Welded Tube Recycling and reuse

Stainless steel is 100% recyclable. An average stainless steel object is composed of about 60% recycled material of which approximately 40% originates from end-of-life products and about 60% comes from manufacturing processes.

There is a secondary market that recycles usable scrap for many stainless steel markets. The product is mostly coil, sheet and blanks. This material is purchased at a less-than-prime price and sold to commercial quality stampers and sheet metal houses. The material may have scratches, pits and dents but is made to the current specifications.
