Malleable iron pipe fittings definition are metal fittings designs to connect and secure pipework. Malleable Iron Galvanized Pipe Fittings are essential components using in plumbing and industrial systems. They are commonly using in various applications, from water supply to gas lines. Here are the types of malleable iron galvanized pipe fittings and instructions for installation:
Types of Malleable Iron Galvanized Pipe Fittings
- Elbows: Available in 45° and 90° angles, these fittings allow changes in direction within the pipeline.
- Tees: Galvanized tee fittings are essential components using in plumbing, infrastructure, and mechanical systems. Used to create a T-shaped junction between three pipes.
- Couplings: Connect two pipes end-to-end.
- Unions: Allow easy disconnection of pipes for maintenance.
- Bushings: Used to reduce the size of a threaded opening.
- Locknuts: Secure threaded connections.
- Caps: Seal the end of a pipe.
- Street Elbows: Used when pipes need to change direction at a street corner.
- Crosses: Connect four pipes at right angles.
- Floor Flanges: Provide a secure base for vertical pipes.
- Reducing Fittings: Used when connecting pipes of different diameters.
Installation Steps of Malleable Iron Galvanized Pipe Fittings
- Prepare the Pipes: Cut the pipes to the required length and remove any burrs or debris from the ends.
- Prepare the Fittings: Clean the threads of the fittings with a wire brush or cloth to remove dirt or debris.
- Apply Thread Sealant: Apply thread sealant to the male threads of the fitting.
- Assemble the Pipes and Fittings: Insert one end of the unthreaded galvanized pipe into the coupling. Align the coupling end with the drawn line on the pipe. Insert the second pipe into the coupling and center the coupling between the two drawn lines.
- Tighten the Fastening Bolts: Use a torque spanner set to the specified torque requirement to tighten the bolts evenly until secure.
Connecting Malleable Iron Galvanized Pipes
Without Threads:
- Measure the width of each pipe.
- Choose a coupling that fits the inside width where the pipe and connector join.
- If pipe widths differ, use a stepped coupling.
- Insert one end of the unthreaded galvanized pipe into the fitting.
- Align the coupling end with the drawn line on the pipe.
- Insert the second pipe into the coupling, centered between the two drawn lines.
- Tighten the fastening bolts until the coupling securely holds the pipe in place.
With Threads:
- Clean the threads of the fittings.
- Apply thread sealant to the male threads.
- Screw the fittings together.
Remember that malleable iron fittings are not as strong as other options, so avoid additional welding. However, their heating process gives them great tensile strength, making them durable and long-lasting. Always follow industry standards and malleable iron galvanized pipe fittings factory guidelines during installation and ensure leak-free connections.
