Carbon SteelDurability and cost are key issues when choosing a product. Installers of piping systems understand that choosing carbon steel is the greener option compared to other materials for it can greatly lower overheads by being more cost effective and durable. A principal advantage of fitting carbon steel is its anti-corrosive nature in closed-circuit systems.

To ensure the piping system is durable, the system should be commissioned, installed, handled and stored in accordance with the manufacturer’s guidelines to avoid issues in the future.

Keeping It Clean and Dry

Before fitting, always try to protect pipes from damage and dirt, or if possible, do not remove the original packaging. Try to avoid installing the pipes near stainless-steel as this may cause corrosion. As standard, always keep the pipes free from moisture and protect from the elements. The temperature should also be controlled and maintained above dew point. If the pipes are used for chilled liquid, always maintain a vapour barrier in areas where there is possible condensation.

Some carbon steel pipes have a plastic coating, which means it won’t need additional protection besides the pipe ends and uncovered fittings.

Keep It Oxygen Free

Corrosion is likely to occur if there is oxygen in the circuit, especially in concentrations in excess of 0.1 g/m3. This will likely occur in automatic air vent valves, screw connections or compression glands if the heating system has negative pressure. When supplementing and filling with water, the chances of corrosion damage are lesser because the measure of oxygen will be very low.

Proper Commissioning

When there is water and residual oxygen present in the pipework, it will start to corrode and become almost impossible to stop.

By following the guideline of manufacturers, carbon steel is an eco-friendly, long-lasting and lower-cost (for pressed pipes) alternative, making it a popular choice compared with its competitors.
