• Wall Thickness – 1.5mm
• Internal Diameter – 41.45mm

We also carry a wide range of mild steel sheet metal, angle iron and flat bar.

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.

• Bending & Forming – Fair. You could only bend this tubing with bending tools but not by hand
• Corrosion Resistance – Poor. Mild steel is uncoated, so there is no additional protection against corrosion
• Machining & Grinding – Good. Mild steel is the metal choice for many forms of machining and grinding, but stainless steel can also offer good results
• Welding – Excellent. You could easily weld with this tubing to suit your requirements
• Painting – Good. We suggest that a mild steel product is always used when a layer of paint needs to be applied. Galvanised and stainless steel will not take paint
• Wear Resistance – Fair. As there is no protective layer, we suggest stainless steel or galvanised steel if you require a stronger wear resistance

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.

FAQs About This Product

How Do I Identify Defects or Issues in a Mild Steel Steel Pipes?

Identifying defects or issues in mild steel pipes is crucial to ensure their longevity and safe operation. The following are common ways to detect and identify defects in these pipes:

Visual Inspection:

The first and most straightforward method is a visual inspection. Regularly examining the pipe’s exterior can reveal obvious signs of wear, damage or corrosion. Look for:

• Rust spots or pitting: Indicators of corrosion, which can weaken the pipe.
• Dents or deformations: They can result from mechanical damage and might compromise the pipe’s integrity.
• Discoloration: This can be an indication of heat damage or chemical reactions.
• Seams or weld areas: These areas can be more susceptible to issues, especially if the welding was not done properly.

Ultrasonic Testing:

Ultrasonic testing is a non-destructive method that uses high-frequency sound waves to detect flaws within the pipe. An ultrasonic device sends sound waves into the pipe, and based on the waves’ reflection, can identify inconsistencies or defects inside the pipe wall, such as cracks or inclusions.

Magnetic Particle Inspection:

For this method, the pipe is magnetised, and iron particles are spread over it. The presence of defects, like cracks or voids, will disrupt the magnetic field, causing the particles to gather at the defect sites, making them visible.

Dye Penetrant Inspection:

This is a method used to detect surface-breaking defects. The pipe is first cleaned, then a dye is applied. After a set time, the dye is removed and a developer is applied. Any cracks or defects will absorb the dye and become visible when the developer is used.

Radiographic Testing:

This involves using X-rays or gamma rays to view the inside of the pipe. Much like medical X-rays, this method provides an image of the pipe’s interior, revealing defects like cracks, voids or inclusions.

Hydrostatic Testing:

This test involves filling the pipe with water and then pressurising it to check its strength and integrity. If there are defects, the pipe might bulge or even burst under pressure.

Eddy Current Testing:

An electromagnetic coil induces eddy currents in the pipe wall. Any disruption to these currents, caused by defects, is detected by a second coil.

When assessing mild steel pipes, it’s essential to conduct regular inspections and tests, especially if the pipes are used in critical applications. If any defects or issues are identified, it’s crucial to address them promptly to prevent further deterioration and potential failures.

What’s the Difference Between Galvanised and Non-Galvanised Mild Steel Steel Pipes?

Galvanised Mild Steel Pipes:

Galvanised mild steel pipes have undergone a galvanising process, which involves coating the steel with a protective layer of zinc. This zinc layer serves as a barrier against environmental elements, providing significant resistance to corrosion and rust. The galvanising process ensures that the pipes have a longer lifespan, especially when used in damp or corrosive environments. In addition to enhanced durability, the zinc coating gives the pipes a distinctive shiny, silvery appearance. Because of these protective properties, galvanised pipes are commonly used in outdoor applications, underground systems, and places where the material is exposed to moisture, such as plumbing or in agricultural settings.

Non-Galvanised Mild Steel Pipes:

In contrast, non-galvanised mild steel pipes lack the protective zinc coating. As a result, they are more susceptible to rust and corrosion when exposed to moisture and oxygen. Without the protective layer, these pipes tend to have a duller, grey appearance characteristic of raw steel. While they might be more affordable upfront than their galvanised counterparts, they may require additional protective measures, such as painting or other coatings, if used in environments where corrosion is a concern. Non-galvanised pipes are often chosen for indoor applications, where they are less likely to be exposed to harsh environmental conditions, or in situations where they will be coated or enclosed, rendering the galvanising process unnecessary.

Is it Possible to Paint Mild Steel Steel Pipes?

Yes, it is entirely possible to paint mild steel pipes, and doing so can offer both aesthetic and protective benefits. Before painting, it’s essential to prepare the surface correctly to ensure good adhesion and longevity of the paint. Initially, any rust, grease or old paint should be thoroughly removed, typically using wire brushes or sandpaper. Cleaning the pipe with a degreaser or a mild detergent helps to remove any oils or residues that might prevent the paint from adhering properly. Once the surface is clean and dry, applying a primer designed for metal surfaces will help the paint bond effectively and provide an extra layer of protection against corrosion. After the primer has dried, the pipe can be painted using a suitable metal paint. This paint will not only give the mild steel pipe the desired color but also add an additional protective layer against environmental factors, further extending the pipe’s lifespan.
