The proper pipe fittings and flanges let your equipment do the work that you intend it to do. The various types of pipe fittings include adapters, bulkhead fittings, plugs, rigid couplings, flexible couplings, 90 degree elbows, 45 degree elbows, reducing elbows, flanges, nipples, concentric reducers, eccentric reducers, side outlet eyes, standard eyes, reducing eyes, bullhead eyes, unions, standard wyes, reducing wyes and many more. You should select the right fitting for your application among the wide range of fitting types and sizes offered.
Common points to consider:
The integrity of any fitting for proper functioning depends upon the following:

  • Selection of correct components or fittings appropriate for the application
  • Careful preparation and cleaning
  • Careful installation and assembly
  • Correct tightening and loading
Selecting Your Pipe Fittings:
The points to consider are as follows:
  • Consider the Tubing Used: For instance, barbed fittings work better in flexible tubing while compression fittings work best with rigid tubing.
  • Determine Material Compatibility: Material selection plays a vital role in the proper working of fittings. There are certain fluids which are not compatible with fitting material and these fittings cause leakage or system damage. It is very essential to check the material compatibility of your fluid with any chemicals.
  • Check Temperature and Pressure Conditions: Appropriate temperature and pressure ratings are needed for proper operating conditions. It is necessary to know whether the fittings are capable of performing at their maximum temperature and maximum pressure ratings because most fittings cannot perform both the task simultaneously.
