Cast iron pipes were used before the invention of PVC pipes and until then they have been the choice for major refurbishment works and for water and sewage drains. Many older homes still have these pipes and may need to be replaced. This article will teach you how to cut cast iron pipes.
Steps
Method 1 of 2: Using a Pipe Cutter
Step 1. Use chalk to mark the cut lines on the pipe
Try to make them as straight as possible.
Step 2. Wrap the chain of the cutter around the pipe evenly
Make sure there are as many cutting wheels as possible around the pipe.
Step 3. Apply pressure to the handles of the cutter so that the wheels can cut the tube
The tube may need to be scored several times before the final cut can be made.
You will probably have to twist the pipe slightly before you can cut it completely if you are doing these operations on the ground
Step 4. Repeat these steps for all other lines marked with chalk
Method 2 of 2: Using a Jigsaw
Step 1. Set up the hacksaw with a long metal cutting blade
Many of these blades are made with carbide or diamond serrations to cut particularly hard materials.
Step 2. Use chalk to mark the cutting lines
Signal as straight as possible. Hold the tube firmly in place. The work can be easier if you get help from another person who holds the tube still.
Step 3. Set the saw to low speed and let the blade do the work for you
Don't put too much pressure on it as you could trigger the blade.
Advice
Diamond serrated blades are the newest, most advanced technology, and tend to last longer than their carbide counterparts
