Features of Malleable Iron Pipe Fittings

 

 

Premium quality

Professional engineers can provide sprocket expertise consultation and professional advice on product selection, design, installation, and maintenance.

Excellent corrosion resistance

Surface treatments such as black oxidation or galvanizing improve the corrosion resistance of pipe fittings and enable them to be used in humid and corrosive environments for a long time.

Flexibility

The raw material of Malleable Iron Pipe Fittings has good ductility, so it is very easy to shape. It can be easily processed into various sizes and shapes to suit different pipe needs.

Wide range of applications

Malleable Cast Iron Fittings are suitable for water supply, and drainage systems and are also very common in industries such as oil, gas, and pharmaceuticals.

Easy to install

Various connectors, unions, plugs & bushings are precisely shaped, lengthed, and angled, and clear threads make them easy to join and assemble.

 

Common types of black pipe fittings

 

Elbows

Elbows are common pipe fittings used to change the flow direction of a pipe. Jianzhi provides 45-degree and 90-degree elbows in various sizes. 

Tees

Tees can change the direction of pipes and connect different branch pipes. We can provide ordinary tees and reducer tees that can change the flow rate.

Bushing Reducers

Bushing reducers can connect pipes of different diameters. You can use it to extend pipes and reduce fluid flow.

Couplings

Couplings connect two pipes together and keep the pipes tight. Some Couplings can also provide shock absorption and noise reduction functions

Unions

Unions are very similar to couplings, but can realize quick maintenance of the pipeline. It allows you to easily connect or disconnect pipes without having to turn the threads into place.

Plugs

Plugs are mainly used to plug the ends of pipes. It can also help control fluid pressure in pipes and prevent fluid leaks or foreign matter from entering the pipes.

 

 

Strict quality assurance

Our Malleable Iron Pipe Fittings are manufactured to strict standards, and each fitting has precise specifications (1/8" to 6"). Our galvanized products all have good corrosion resistance, meet low lead requirements, and will not cause pollution to fluids. In addition, all our pipe fittings undergo strict testing and quality inspection.

FAQ

Q: What are malleable iron pipe fittings used for?

A: Malleable iron pipe fittings are often used to join metal pipes. The diverse types and sizes allow it to connect various pipelines in areas such as water supply systems, gas systems, petroleum and chemical industries, and fire protection systems.

Q: What is the difference between ductile iron and malleable iron fittings?

A: Ductile iron is very similar to malleable iron in that they are both very durable. Ductile iron can be used to cast larger pipes, while malleable iron has higher strength and hardness.

Q: Can I weld malleable iron pipe fittings?

A: Yes. However, welding can alter the structural integrity and performance of malleable iron pipe fittings. Welding of fittings in pressurized piping systems should be avoided because it may create a safety hazard.

Q: What is the difference between cast iron and malleable iron?

A: Malleable cast iron has better ductility, so it is easier to process than cast iron and is suitable for pipe fittings with complex shapes. The high hardness also makes it very impact-resistant. Cast iron contains approximately 2% carbon, which makes it stronger and has good resistance to heat and corrosion. But its processing also becomes more difficult.

Q: What's the difference between steel and malleable iron?

A: The high carbon content makes steel stronger than malleable iron, but malleable iron undergoes multiple rolling and surface treatments during the production process, having better ductility and formability. At the same time, Malleable Iron is heavier than steel, so the weight of Malleable Iron fittings is about two to three times that of steel pipe fittings.

Q: Which is better, ductile iron pipe fittings or PVC pipe fittings?

A: The impact strength of ductile iron pipe fittings is about 13 times that of PVC pipe fittings, and the tensile strength is more than 9 times that of PVC pipe fittings. At the same time, ductile iron pipe fittings can withstand greater stress and pressure, while PVC pipe fittings may fail faster when faced with pressure.

Q: What is black malleable iron pipe used for?

A: Black malleable iron pipe with a seamless design has good wear resistance, fatigue resistance, corrosion resistance, and high-temperature resistance, so it can be used to transport combustible gases such as propane gas and can also be used in fire sprinkler systems.

Q: Can malleable iron be galvanized?

A: Yes. Through galvanizing, the surface of malleable iron will have a layer of zinc, which has good corrosion resistance and anti-rust capabilities. Our galvanized malleable fittings can be used in humid environments for a long time and will not fade easily.

Q: Is malleable cast iron strong?

A: Yes. Malleable cast iron is annealed so it has greater strength while maintaining ductility.

Q: Can malleable iron rust?

A: If malleable iron has a bare metal surface and is exposed to oxygen in the presence of moisture, it can rust.

Q: What is a cast iron fitting with an angle of 45 degrees called?

A: This kind of pipe fitting is called a 45° Pipe Elbow, 45 bends, or 45 ells. It can provide a 45-degree bending angle and change the direction of the fluid in the pipe.

Q: How do you connect black pipe together?

A: These pipes are connected via Malleable Iron Pipe Fittings. Generally speaking, threads provide good connectivity and tightness. Materials such as Teflon tape can ensure no leaks in the pipes.

Q: What is the difference between a bushing and a hex bushing?

A: They are made of galvanized steel and have good corrosion resistance. The special thing about hex bushing is that it is hexagonal in shape. It utilizes the internal hexagonal structure to provide a stronger fastening effect and is smaller and more convenient than ordinary bushings.

Q: What is the temperature limit for black iron plugs?

A: Black iron plugs generally accept operating temperatures between -30°C and 400°C, making them ideal for high-temperature environments.

Q: What are the connection methods of cast iron pipe?

A: Common connection methods for cast iron pipes include flange connection, rubber gasket connection, welded connection, threaded connection, cast iron casing connection, mechanical connection, etc.
