Pressure pipe fittings are one of those vital pieces of equipment that are needed in a whole range of industries. Because they’re so important you need to make sure that you’re getting the best quality possible, and also that you’re using the right fitting for the job and that it’s been made to the correct standards. So, here’s a quick run through so you’re familiar with most of the essential pressure fittings, from your weldolets to your couplings.

Weldolets

Weldolets are just one of the many pressure pipe fittings available, being self-reinforced fittings that are used instead of standard tees when the pressure in the pipe is too extreme for anything else.

Couplings

Couplings are short lengths of pipe used to connect other pieces of tube together either through welding, brazing or soldering. They’re used in pipes that are heavily pressurised and are build to be able to withstand the force of that.

Socket weld

A socket weld is a small pipe attachment that’s used when the pipe has to be inserted into a recessed part of a fitting or valve. The pipe is welded in place to withstand heavy pressure, utilising the socket weld.

BSPT and BSPP – British Standard Pipe Taper Thread and Parallel Thread

BSPT and BSPP are types of screw thread that are used to seal pipe ends by connecting an external thread (male) with an internal thread (female). They differ in terms of their size and diameter: BSPT types have a changing diameter throughout the length of the thread, whereas the diameter of all BSPP types remains constant throughout.

Where to buy pressure fittings

As with anything, there are always plenty of places that you can go to find pressure pipe fittings. Searching online is a great place to go as you’ll often be able to buy in bulk, will get great customer service and are more than likely to be able to find just what you’re looking for.
