Types of Pipe Black iron pipe is not good for carrying water in drainage or supply systems because it rusts too quickly and will stop working in a short amount of time.
Due to its reasonable resistance to corrosion and relatively low cost, galvanized pipe is the most common type utilized for home supply and drainage lines. It is less resistant to corrosion than pipe made of black iron, but its rating is lower than that of brass or copper.
Drainage systems are the primary application for cast iron pipe, which typically has a large diameter.
In addition to offering the advantages of iron pipe, brass pipe does not knot rust. It also offers less resistance to the flow of water due to its smoother interior wall section. As a result, it has taken the place of galvanized iron pipe in a lot of homes with "better" plumbing.
Tools for the job Although it is impractical to purchase every tool needed for home improvement and repair, there are some specialized tools that the homeowner should have on hand. Hardware stores allow you to rent some of the additional, more specialized and more expensive tools. But if you do a lot of plumbing, whether it's repairs or improvements, it might be best to buy some of the tools you normally rent.
1. When cutting pipe made of brass or iron, you absolutely need a vise to keep the pipe in place while it is cut. Whether you use copper tubing or not is irrelevant. You can use pipe jaws in a standard vise or purchase a pipe vise.
2. Pipe cutting is made simpler by pipe cutters; They do the job better and faster than a hacksaw because the pipe's end is cut perfectly flush. When threading brass or iron pipe or flare topper tubing for solder-less conlectors is required, this square cut is crucial.
3. The internal burrs that result from cutting can be removed with a pipe reamer. Adjustable for a variety of pipe sizes, reamers are available in a variety of diameters. With a brace, they are used. However, the best pipe cutters include a reamer for cutting copper tubing.
4. Threading the end of a brass or iron pipe is done with pipe dies. Typically, they come in sets with a handle.
5. Internal threads are made with pipe taps. On the shank, the tap's usual size is usually marked. When using the table that is included, the recommended tap size is based on the pipe's nominal diameter, not its actual diameter.
6. Depending on their purpose, pipe wrenches vary. Pipe wrenches must have jaws that can securely grasp the round exterior surface. While Stillson wrenches are typically utilized for the task, other options include pipe tongs or strap wrenches, in which a link chain is utilized in place of the jaws.
Other types of wrenches are required for the hexagonal fittings of solderless connectors, the tops of valves and faucets, and other non-round surfaces. For these purposes, an open-end or monkey wrench is ideal. If the surface is taped to stop the pliers' teeth from "chewing" into the metal, you can use parrot-head pliers.
7. The hacksaw can be used to cut tubing or pipe. Since only the forward stroke cuts, position the blade in the frame so that the teeth face forward.
• Use a saw blade with 24 teeth per inch for iron and brass pipe.
• A blade with 32 teeth per inch is best for conduit and thin tubing.
8. When working with copper tubing-soldered fittings and cast iron pipe, a blow torch is required. This could be a pressurized-fuel, disposable can type or a gasoline pump.
9. Soft copper tubing is suited for use with tube benders. The tube can then be bent to any angle without causing the tube's walls to collapse using the tube bender or bending spring. Tube benders typically come in kits, but they can also be purchased in individual sizes.
10. Copper tubing and solderless connectors are used with the flaring tool. There are two types to choose from. One is a tapered unit that is inserted into the tubing and used to flare the pipe by hitting the outside end with a hammer. The second is a yoke unit that can be adjusted to fit copper tubing of different diameters.
11. Air pressure is used to remove pipe obstructions using a standard or one of the specialized types of plungers.
12. Using a "snake," also known as a closet auger, one can physically clear a pipe of obstructions. To clean the pipe, the coiled wire or metal spring steel is pushed through it.
13. The seat of a compression valve or faucet can be resurfaced with the help of a Bibb seat dresser.
Measurements of the Pipe When performing a new installation or a repair, it is essential to accurately measure the pipe. Whether you order the pipe and have it sized and threaded by a professional or cut and thread it yourself, this is crucial.
If a professional will cut and thread the pipe, the easiest way to measure it is to draw the exact pipe diagram and then mark the measurements. The professional can determine each piece's exact size.
You should be able to make a precise dimension drawing or figure out the sizes yourself with the assistance of the tables and diagrams that are included.
Working with Brass and Iron Pipe A hand hacksaw, a power hacksaw, or a pipe cutter can all be used to cut brass and iron pipe. For most jobs, you'll want to use the pipe cutter, but if you need to cut a lot of pieces or if the pipe has a thick wall, the power hacksaw is faster. The pipe cutter has two pressure rollers and a cutting wheel made of special alloy steel. The handle can be turned to adjust and tighten these. The pipe is the center of the tool as a whole.
The action of cutting the pipe creates a shoulder on the outside and a burr on the inside of the pipe. If you don't get rid of the inside burr, the ragged edges will catch dirt and other solid objects and prevent the flow. The tool you use to remove the burr is the burring reamer.
Pipe Threading Pipe fittings have tapered threads that must be turned up tight and leak-proof with specialized dies known as pipe dies. The dies are turned with a stock, and the same stock can be used to thread various sizes of pipe. The majority of pipe dies can be adjusted to cut threads of varying depths, allowing for either a longer or shorter thread at the pipe's end. Hold the stock and secure the work before cutting the threads; then proceed as if you were using a different die; keep the work running smoothly. When the process is complete, it is a good idea to test the thread using a standard pipe fitting.
Pipe Assembly Red lead is typically used as a seal in threaded water pipe joints. Graphite paint is used to seal the threads of steam pipes. Only apply the sealing compound to the threads of the pipe to prevent it from entering the pipe and causing a dangerous obstruction. Before using the sealing compound, make sure the threads are clean.
Hand-screwing threaded joints and tightening them with a pipe wrench, also known as a "Stillson," are the best methods. During assembly, the pipe should be held in a pipe vise; however, if a pipe vise is not available, another pipe wrench can be used to hold the pipe in place.
How much should a joint be tightened? The best teacher is experience. On a properly cut pipe thread, there will typically be two or three unused threads. The wedging action of the tapered thread may cause the fitting to split if all of the threads are utilized.
Working with Copper Tubing: Weekend projects like installing plumbing in a new bathroom, piping a darkroom sink or cellar tub, or running underground lines to outdoor pools or sprinkler systems only require a hacksaw to make a few cuts and a small torch to solder connections together.
For galvanized-steel plumbing, there is no need for Stillsons, threading dies, or pipe vises. You won't even need to solder anything if you use fittings that simply screw together.
