How to connect explosion-proof floor drain and galvanized pipe threaded connection?

To connect an explosion-proof floor drain to a galvanized pipe using a threaded connection, follow these steps:

Materials and Tools Needed

Explosion-proof floor drain with threaded outlet

● Galvanized steel pipe with threaded ends

● Pipe wrench or adjustable wrench

● Pipe threader (if threading the pipe yourself)

● Thread sealant (Teflon tape or pipe dope)

● Pipe cutter or hacksaw (if cutting the pipe to length)

● Deburring tool or file (if cutting the pipe to smooth the edges)

Connection steps

1.Prepare the Galvanized Pipe:

If the galvanized pipe is not pre-threaded, use a pipe cutter or hacksaw to cut the pipe to the desired length.

Deburr the cut ends using a deburring tool or file to remove any sharp edges and ensure a smooth threading process.

Use a pipe threader to thread the cut end of the pipe. Ensure the threads are clean and uniform.

2.Apply Thread Sealant:

Clean the threads on both the galvanized pipe and the threaded outlet of the explosion-proof floor drain.

Apply Teflon tape or pipe dope to the male threads of the galvanized pipe. If using Teflon tape, wrap it clockwise (in the direction of the threads) to ensure it stays in place when screwing the pieces together. If using pipe dope, apply an even coat to the threads.

3.Thread the Pipe into the Floor Drain:

Insert the threaded end of the galvanized pipe into the threaded outlet of the explosion-proof floor drain.

Hand-tighten the pipe into the drain to ensure it starts threading correctly and doesn't cross-thread.

4.Tighten the Connection:

Use a pipe wrench or adjustable wrench to tighten the connection. Ensure the pipe is secure, but avoid over-tightening, which can damage the threads or crack the fittings.

If necessary, use two wrenches – one to hold the drain steady and the other to turn the pipe – to achieve a tight connection.

5.Check for Leaks:

Once the connection is tight, check for leaks by running water through the system. Look for any drips or signs of moisture around the threaded connection.

If any leaks are detected, tighten the connection slightly more. If leaks persist, disassemble the connection, reapply thread sealant, and retighten.

Safety Tips

● Wear appropriate safety gear: Use gloves and safety glasses to protect yourself from sharp edges and debris while cutting and threading the pipe.

● Ensure proper ventilation: When using thread sealants, especially pipe dope, ensure good ventilation to avoid inhaling fumes.

● Follow manufacturer instructions: Adhere to the manufacturer's instructions for both the floor drain and the thread sealant for optimal results.

Following these steps will ensure a secure and leak-free connection between the explosion-proof floor drain and the galvanized pipe using a threaded connection.
