A drain pipe is a pipe that drains water, or other liquids, from one area to another. When most of us think of drain pipes, we think of the pipes in our homes that move water from our homes to the sewer or septic systems. There are many other types of drainage needed in our world, and many other types of drain pipes that can accomplish the task.
Corrugated polythene is a very common drain pipe that is made of flexible plastic. Although it is flexible, it is extremely durable and this pipe can be bent into almost any shape that you need in order to move water from one place to another. It is commonly used for industrial-type situations such as under roads, fields and culverts.
This is another common drainage pipe that has many uses. Anywhere that you need heavy-duty pipes, this is the pipe you will need. PVC pipe is strong, can withstand a lot of pressure and can be found in many different sizes. Another advantage that PVC offers is the fact that it is easy to work with. Joints are just glued together with PVC joint glue, so there is no need for welding or soldering. The only real drawback to this type of pipe is that it is rigid.
Cast-iron pipes have been used for many years because they are tough and long lasting. Cast-iron pipes are generally used in situations where large pipes are required, such as in municipal drainage applications. These will be the pipes that run under streets and roadways that take run-off water to the waste-water plant for recycling. Municipalities use this type of pipe because it can last 100 years or more, with minimal maintenance.
Copper pipes were the staple for residential water and drainage lines for many years. Copper was used extensively in the past because it will not rust and it was very inexpensive, but times have changed. Copper lines are no longer in wide usage due to the fact that copper is now quite expensive and PVC and plastic water lines now do the job that copper was used for. Another liability of copper lines is that they have to be well insulated in cold climates because they will burst if they freeze. PVC and plastic lines are cheaper and easier to work with, and they are less likely to burst if they freeze.
