Forged fittings are formed via forging and machining from solid blocks of steel, stainless steel in our case to meet the final required shape set within the tolerances of the applicable specifications. These are split into two categories of forged fittings, namely Socket Weld Fittings and Threaded Fittings. These are further categorized in ratings of 3000#/6000#/9000#, the higher the class rating, the higher the pressure and temperature a fitting would be able to withstand.

Socket Weld Fittings are connected to pipes by fillet welds. It is typically used for when a strong and long-lasting connection is required. These are very reliable but also very time consuming due to welding of a small part.  

Threaded fittings are screwed on fittings. It is typically used for less critical piping systems such as water distribution or for low pressure installations that are not subject to vibrations, elongations and bending forces. There are two types of common threading that one would find if they purchase threaded fittings and they are:

1. BSP – BSP refers to British Standard Pipe and can be further divided into BSPT (Tapered) and BSPP (Parallel) as one of the few variations
2. NPT – NPT refers to National Pipe Tapered.
   
   

Both these socket weld and threaded fittings are further categorized in ratings of 3000#/6000#/9000#, the higher the class rating, the higher the pressure and temperature a fitting would be able to withstand.
