Connecting Steel Pipe

• When first connecting steel pipe, you will need the proper fittings and threads. The fittings are the joints that connect pipe to pipe, and the threads are the grooves in the pipe that allow them to be screwed into the fitting to form the proper type of seal. However, simply screwing the pipes in will not always seal them. Sometimes the threads will not fit exactly, or small errors in the metal will create pockets where air or gas can escape. If order to stop leaks from developing, you will need to seal these joints.
  
  There are two popular methods for sealing steel pipe as you screw them in. In you have any Teflon tape, you can seal the joints and coupling with it. This will create a watertight seal around the outside of the pipe, which protects it in case leaks develop. The second option, which is often more dependable, is a pipe sealing compound that placed along the inside of the pipe before it is screwed in. The compound locks the threads in place and prevents leaks on the inside of the pipe structure.
  
  

Sealing Leaks and Cracks

• If your steel pipe do crack or develop leaks, locate where the leak is coming from. Steel pipes tend to be more flexible than other versions of metal pipes, and if they develop leaks it is likely to be caused by a warped section of steel. After you find the leak, you will need to choose rather to replace the pipe completely, or seal the leak before it can do any more damage.
  
  There are two types of sealing options. The first is a metal clamp that fits over the pipe, clamping down on the leaking section and preventing any more water from escaping. If the crack looks to be well-contained but wide, the clamp may be the best option. The second options is a seal that you will need to wrap around the entire pipe and bond in place with adhesive. Use this type of seal if the leak is small and the crack is slight. Both options can be purchased at plumbing stores or online.
