What Pipe To Use With Pipe Clamps 

There are two main types of pipes used with pipe clamps: galvanized pipes and black steel pipes.

Although either work well for a variety of jobs, it is best to compare the two in terms of material, features, and cost. 

Galvanized Pipe 

Galvanized pipes are steel pipes coated thoroughly with a protective layer of zinc. The addition of zinc strengthens the pipes and prevents them from corroding and rusting away.

With a variety of applications, galvanized pipes are mostly used for water supply lines.


  • Free from external corrosion. 
  • Rust protection. 
  • Longer life span. 
  • Smooth outer exterior. 
  • Easy inspection.


  • Prone to internal corrosion. 
  • Causes plaque. 
  • Costly. 

Black Steel Pipe

Black steel pipes are regular pipes without zinc galvanization. Instead, dark-colored iron oxide coats the surface, giving them a rather scaly appearance. 


  • Best for natural/propane gas. 
  • Fire resistant. 
  • Externally stronger and robust.
  • Cheaper compared to galvanized pipes. 


  • Prone to corrosion. 
  • Scaly finish.

Do Pipe Clamps Need To Be Threaded?

Whether or not pipe clamp should be threaded depends entirely on the style of the pipe clamps you have purchased. 

If your pipe clamps have a clutch mechanism, the pipes can slide into the clamp end until they firmly rest against the back wall. For such a design, you do not require any threading. 

However, if your pipe clamps do not have a clutch mechanism and instead have an end with a crank or one that accepts a threaded pipe, then your pipe clamps will be threaded.

This threaded end of the pipe will screw into one of the pipe clamps ends.

It is helpful to have both ends of the pipes threaded in some cases, especially if you wish to prevent sliding of the pipe from either end.

Hence, you can always opt for screwing an end cap onto the pipe to thread it.

How Many Pipe Clamps Do I Need? 

The number of pipe clamps you need has a lot to do with the size of the project you’re working on, the length of the pipes you’re using, your personal preference in clamp size, and the overall amount of storage space you have. 

If you’re working on a small-scale project, you might not need as many pipe clamps as you would when working on a large-scale project.

However, if you often find yourself indulging in projects that require pipe clamps, regardless of the size of the project, you can always opt for storing the pipe clamps after buying them in bulk. 

Don’t have a lot of storage space for larger pipe clamps? You can always use shorter ones and join them together to increase their length when required.

Remember, you will need to have threaded ends on your pipes for this. 


Now you have all the information needed to make your decision about which pipe clamp size is right for your project.

If you still aren’t sure, you can always pick up a few of each so that you’re prepared for whatever project comes your way.
