Two widely used materials for pipe fittings can cater to different needs

Nov 24, 2023 | NEWS

China is already the largest producer and consumer of construction materials in the world.

The output of main building materials products such as cement, flat glass, building sanitary ceramics, stone and pipe materials ranks first in the world for many years. At the same time, the quality of Chinese pipe fittings and other building materials products continues to improve, the consumption of energy and raw materials decreases year by year, a variety of new building materials continue to emerge, building materials products continue to upgrade, Chinese pipe fittings have a very high degree of recognition in the world.

Pipe fittings refer to all kinds of fittings used to connect, convert, support and divert pipes, and they are an indispensable part of the pipeline system. The function of pipe fittings is not only to simply connect the pipe, but also to change the flow direction, adjust the flow and so on.

It can be said that fittings for the piping system, just as joints for the human body, the quality of the pipe determines the operation of the piping system.

At present, malleable Iron Pipe fittings occupy an extremely important position in China and even all over the world. Compared with the most traditional and primitive key materials, malleable Iron Pipe fittings have many irreplaceable advantages.

Next, let’s learn about it with YINUO,China.

Different uses of different malleable Iron Pipe fittings

As mentioned above, the main functions of pipe fittings are connecting, shunting, increasing branches, etc., and the functions of malleable iron pipe fittings are also these, which can be roughly divided into:

1. The malleable iron pipe fittings used for connecting pipes to each other are: flange, live joint, pipe hoop, clamp, clamp, throat hoop and so on.

2.Malleable iron Pipe fittings that change the direction of the pipe: elbows, bends.

3.Malleable iron Pipe fittings for changing pipe diameter: variable diameter (reducer), reducer elbow, branch table, reinforcement pipe.

4.Malleable iron increase the pipe fittings of pipeline branches: three-way and four-way.

5.Malleable iron pipe fittings for pipeline sealing: gasket, raw material belt, wire hemp, flange blind plate, pipe plug, blind plate, head, welding plug.

6. Malleable iron pipe fittings for pipeline fixation: clasp, drag hook, lifting ring, bracket, pipe clamp, etc.

7. Malleable iron pipe fittings used to cap or plug the end of a pipe:Malleable Iron Plug Fittings.Plug fittings are special compared to other types of pipe fittings for its shape.

Malleable iron plug fittings

Malleable iron plug fittings are metallic threaded fitting which provides strength and machinability at the end of the pipe in the shape of a cap. They can be used for both temporary and permanent capping of pipe connections.Malleable iron pipe fittings are available in a range of standard NPT sizes to match common piping,and YINUO,China’s malleable iron plug fittings will allow no flow to pass or leak if tightened fully.

In fact, the most commonly used raw materials for this kind of pipe fittings include not only malleable cast iron, but also hot-dip galvanized(HDG) materials, which mainly depends on the medium and working environment.

Material comparison of plug fittings

Advantages of HDG Iron Plug fittings:

Good anti-corrosion performance

Strong durability

Convenient construction

Disadvantages of HDG Iron Plug fittings:

High cost

Environmental pollution

Surface quality is limited

Features of malleable iron pipe fittings

1. High strength and tensile strength, often used to manufacture parts with high load, heavy load or high speed rotation.

2. High toughness and strength-toughness ratio, that is, it is not easy to fracture under impact and vibration, but does not affect its strength.

3. Good wear resistance, also known as “self-lubricating cast iron”, can be used to manufacture workpieces with high wear resistance.

However, malleable iron also has some shortcomings, such as high shrinkage, easy to produce unique pores and defects and so on.
