22 x 2mm round erw steel tubing is used in many structural and engineering applications. The size refers to the outside diameter and then the thickness of the wall.
ERW means Electric Resistance Welded. ERW tube is made when steel strip is welded to form a tube shape. The tube is continuously seam welded which means that there is a neat weld running along the inside of the tube.
Mild steel round tube is widely used in a variety of applications and also comes in both square and rectangular options.
ERW steel tubing has rapidly become a popular choice in various industries and for good reason. Speciality Metals’ 22mm x 2mm Mild Steel ERW Steel Tubing Round Tube is a highly durable material that offers a wide range of benefits. With its excellent welding, forming, bending and machining abilities, this versatile product can be used in a variety of applications. Not only is it cost-effective, but it’s also recyclable, making it an environmentally friendly choice. Whether you’re looking to create a sturdy structure or simply need a reliable transportation solution, ERW steel tubing is an ideal choice.

Mild steel is a quality strong metal. However it is not rust proof and may do so over time. Please use galvanised or stainless steel if you need resistance to rust. If this metal tube does show signs of rust then simply remove this with WD40 or fine sanding.
The grade of plain steel that we have available has mechanical properties that provide excellent machinability, formability and weldability.
Mild steel can be welded and it’s also suitable for painting. Mild steel is a magnetic grade of metal. Magnets will stick to this sheet but it is not itself a magnet.
Yes, mild Electric Resistance Welded (ERW) steel round tube can be repaired if damaged, depending on the nature and extent of the damage. Here’s a breakdown of how damages in mild ERW steel tubes are typically addressed:
Minor Surface Damages: For superficial scratches, dents or minor corrosion, the affected area can be cleaned, sanded or ground down to remove the imperfection. Once the surface is prepared, it can be re-coated or painted to protect against further corrosion.
Small Holes or Cracks: These can often be repaired through welding. The damaged area should be thoroughly cleaned to remove any contaminants or rust. A qualified welder can then fill the hole or crack using a compatible welding material. After welding, the area is usually ground smooth and then painted or coated to prevent rusting.
Larger Damages: If a section of the tube is significantly damaged, it may be necessary to cut out the damaged section and weld in a new piece. This kind of repair requires careful alignment and skilled welding to ensure the structural integrity of the tube is maintained.
Structural Concerns: If the tube is a critical structural component, any repair should be approached with caution. After repairing, it might be necessary to conduct tests or inspections to ensure the repair meets safety and performance standards. In some cases, replacing the entire tube might be more appropriate than attempting a repair.
Corrosion: If the tube shows signs of widespread corrosion, simply addressing the surface might not be sufficient. Corrosion can compromise the tube’s structural integrity. In cases of extensive corrosion, it’s often more prudent to replace the tube rather than repair it.
Re-coating: If the damage has compromised any protective coatings on the tube, it’s essential to reapply the coating after the repair to protect against future corrosion or damage.
In all repair scenarios, the key is to ensure that the repair restores the tube’s original strength and integrity. It’s often advisable to consult with a materials or structural engineer, especially for significant repairs or when the tube serves a critical structural role. Safety should always be the top priority.
Mild ERW (Electric Resistance Welded) steel round tubes, while durable for many applications, have limitations when it comes to handling abrasive fluids over extended periods. The continuous flow of abrasive materials can cause wear and tear on the inner surfaces of the tube, leading to thinning of the tube walls and eventually, to failures. This wear is accelerated when the abrasive particles are hard, like sand, or when the flow velocity of the fluid is high.
To enhance the longevity of mild steel ERW tubes in such conditions, protective measures are often necessary. One common approach is to line the interior of the tubes with a wear-resistant material, such as ceramic, rubber or specialised coatings, which can serve as a barrier between the abrasive fluid and the steel. Alternatively, for some applications, it might be more appropriate to use tubes made from abrasion-resistant steels or other more durable materials.
In summary, while mild ERW steel round tubes can handle abrasive fluids for a time, their lifespan can be significantly reduced under such conditions. Proper precautions and protective measures are essential to maximize the service life of the tubes in abrasive environments.
Mild ERW (Electric Resistance Welded) steel tubes, while versatile, present some concerns when used in freezing temperatures. As temperatures drop, steel can become more brittle, increasing its vulnerability to cracking under impact or heavy loads. This brittleness, combined with the thermal contraction inherent to all metals in cold conditions, can result in structural misalignments or fitment issues. Furthermore, the combination of moisture and freezing conditions, especially when de-icing salts are present, can accelerate the corrosion process. Welding these tubes in cold conditions demands extra caution, as the susceptibility to cracking is heightened. Additionally, when these tubes transport fluids, the potential expansion of freezing fluids might lead to bursting. Therefore, while mild ERW tubes can function in freezing environments, careful material selection, protective coatings and design considerations are imperative to ensure safety and durability.
