Black iron fitting applications

Often referred to as steel pipes (although not technically accurate), these fittings are very popular due to their durability and mechanical strength. The wholesale pipe fittings material is capable of withstanding high mechanical stresses and can be used for a wide range of applications when used in conjunction with standardized joining methods. Black iron is compatible with water and gases and is most widely used in fire sprinkler systems, as the pipes are very resistant to high temperatures. Although once more popular than today, you will still find black iron pipe/fitting in plumbing and HVAC systems in homes and commercial premises across the country. Water will corrode black iron and therefore it is not suitable for use in plumbing. The advantage of black iron is that, unlike steel, pipes and fittings do not need to be welded together.
