Pipe Fittings & Piping Systems Connections - Complete Guide
WHAT PIPE FITTINGS ARE LISTED?
We carry all pipe fittings that are essential to changing direction of flow, adapting or reducing sizes in piping systems.
Changing flow direction: elbows, tees or crosses. Change the size of the pipe : use of reducers required (reducing tees, reducers).
To connect different components: couplings. To stop flow: caps
A pipe nipple is a short stub of pipe which has a male pipe thread at one or both ends. It used for connecting two other fittings. Nipples are used for connecting pipe, hoses, and valves. Pipe nipples are used in low-pressure piping.
There are different kinds of pipe fittings used in piping systems. The main and most commonly sought are: elbows, tees, reducers, unions, couplings, crosses, caps, swage nipples, plugs, bushings, adapters, outlets, valves & flanges.
These pipe fittings can be found in various pressure classes ranging from 150 PSI to 3000 LB. We also carry 2000# up to 6000# forged carbon steel fittings.
TYPES OF PIPE FITTING CONNECTIONS:
When it comes to the connections - BFO lists various types to accommodate all types of end connection requirements. We carry the largest types and size fittings with the following connections:
- Butt Weld
- Grooved end (mechanical fittings)
- Threaded Fittings - we carry various types of threaded fittings that meet ASME & ANSI requirements:
- NPT, NPS & NPTF
- Push On / Push-to -Connect
- Socket Weld
- Solder Joint
POPULAR PIPE FITTINGS - (threaded featured below)
Pipe bushings are used to join pipes of different sizes - usually by reducing a larger pipe fitting down to a smaller pipe. Bushings are usually threaded inside and outisde. They take up very little space compared to a coupling or union, which serve to achieve the same goal of reducing down sizes. Has a hexagonal head for increased leverage and use with a wrench.
Threaded or socket weld pipe elbows are commonly used if you need to change the direction of flow. Most popular: 90 & 45 degree angles elbows. Elbows are a critical fitting used in plumbing. Street elbows feature male and female threaded ends to easily connect differing pipes or fittings. Side outlet elbows featuring a bend serve similar to a tee. 22-1/2 degree elbows are also available.
Caps are availabe in stainless steel 304 or 316 cast pipe fitting with female National Pipe Taper (NPT) threads. For closing the end of a male pipe. The cap fits over the end of a male pipe to stop flow. They are availble also with hex and square heads for increased leverage and use with a wrench during installation and disassembly.
Reducing Couplings/Bell Reducers
Pipe couplings are used to lengthen the run of a pipe or change pipe sizes. When reducing this becomes known as a bell reducer. Available with female threads or socket weld.
Pipe Tees are T-shaped with two outlets - at 90° to the connection to the main line. It is a short piece of pipe with a lateral outlet. Pipe tees are used to connect pipelines with a pipe at a right angle with the line. Tees are sized according to their run*. When the run of a tee is smaller than the side outlet*, it becomes a "bull head" fitting.
Run* - the horizontal or straight-through dimension of the fitting and the side outlet
Side outlet* - the "top" of the fitting, 90 degrees off the run
Unions are an alternative to couplings. Unions rely upon their own nut to create a seal between the pipe ends. This makes them the perfect choice for connecting two fixed pipes that are unable to be threaded into a regular coupling. Unions also make future repairs that much easier. Dielectric unions are used to join pipes of different metals by providing a barrier against galvanic corrosion. Unions are not to be used with natural and LP gas.
