The differences between Malleable Iron Pipe Fittings and Grooved Pipe Fittings

Malleable iron pipe fittings are also known as malleable iron fittings. While grooved pipe fittings are available in a variety of materials, such as ductile iron, stainless steel, and steel with a plastic coating.

The difference between malleable iron fittings and grooved pipe fittings

In both cases, the materials and occasions used are different, and there is no overlap between the two. The use of all grooved pipe fittings has become very popular in the field of fire protection. In terms of use, grooved pipe fittings are expected to gradually become the mainstream method for domestic pipeline connection. Malleable iron pipe fittings are used primarily in environments where the working pressure is generally within 0.6MPa. Grooved pipe fittings or other methods should be used when operating under particularly high pressure. As a result, the ends of malleable iron pipe fittings have a thicker appearance. In order to increase the connection strength, this process is primarily applied when the pipeline is extended, branched, and turned.

What are some of the applications of malleable iron pipe fittings?

Malleable iron pipe fittings are often used in industrial and agricultural production, such as for water treatment, fire protection, irrigation, etc.

Why are malleable iron pipe fittings treated with anti-rust agents?

Malleable iron pipe fittings are made of malleable iron, which is susceptible to rust when exposed to the air. As an example, when malleable iron pipe fittings are used in fire protection systems or water supply systems, because of the humid environment, they are prone to corrosion, so manufacturers of malleable iron pipe fittings like Hebei Jianzhi Casting Group will apply anti-rust treatments to the pipes. The surface anti-rust treatment of malleable iron pipe fittings can be divided into two types: hot-dip galvanizing and cold-galvanizing. Among these two kinds of anti-rust treatment, the hot-dip galvanizing anti-rust process is more expensive, and its anti-rust effect is also more reliable, whereas cold-dip galvanizing anti-rust treatment forms a layer of zinc metal film on the surface of malleable iron pipe fittings, and this layer is easy to fall off. Therefore, we generally recommend the use of malleable iron pipe fittings for anti-rust treatment and hot-dip galvanizing.

Additionally, it should be noted that the thread connection method used by malleable iron pipe fittings is generally referred to as thread pipe fittings. Despite the fact that all malleable iron pipe fittings on the market are galvanized pipe fittings, it can also be said that most galvanized iron pipe fittings refer to malleable iron pipe fittings. Galvanized pipe fittings, however, are not equivalent to malleable iron pipe fittings. Please be sure to correctly identify the desired product as malleable iron pipe fittings when ordering, since some galvanized welded pipe fittings are also known as galvanized pipe fittings.
