Malleable iron fittings are components that integrate various systems, including all irrigation systems. They offer a wide range of uses thanks to their key features, including:

• Versatility;
• Durability;

This type of connection withstands extreme conditions and is ideal for irrigation systems, as the components are constructed of malleable iron. Regarding its purpose, it's worth noting that forged connections are present in many hydraulic systems, such as those for deep wells, for example.

Main features of malleable iron connection

As mentioned previously, malleable iron fittings are made from cast iron. This material , in its raw state, contains carbon. When heat-treated to become malleable, other components are commonly included in the fitting, such as:

• Annealing graphite;
• Ferrite;

Even after this process, it is not common to find a high or even significant amount of some carbides in the component.

What are the properties of malleable iron fitting?

Malleable iron fittings have functional and material properties, which relate to their composition and how they directly affect the part's intended use. The Brazilian Association of Technical Standards (ABNT) establishes the properties of malleable iron fittings, including:

• Mechanical resistance;
• Corrosion resistance;
• Wear resistance.

Application of malleable iron connection

The applications of this type of connection are directly linked to the use of malleable iron, employed in almost all branches of industry. Because the sector is broad, versatile, and technologically advanced, the connection can be found in a variety of systems, machines, and complete equipment.

What is striking is that malleable iron is considered a material with noble properties and, therefore, is a fundamental item in structures that require differentiated properties, fundamental in the electrical, automotive and railway industries, for example.

Regarding the application of this type of connection, its isometric views are always considered for professional use. Regarding isometric views, it's worth highlighting the following points:

• The malleable iron connection allows you to locate the necessary parts in advance;
• Malleable iron fitting is ideal for tubular dimensions;
• The malleable iron connection is ideal for large quantities of material.

It is very common to find malleable iron connections in conducting equipment made of the following materials:

• Water;
• Gas;
• Steam;
• Oil;
• Hydraulic applications.

Rules

Malleable iron fittings are manufactured according to compliance standards established by ABNT and other institutions. See below:

• ABNT NBR 6943;
• ISO 49;
• EN 10242;
• Typical production specifications of the Tupy connection.
