What are the advantages of pipe connectors over flanges?

Previously we used to connect the pipeline is mainly used when the flange, the advantages of the flange has a strong pressure, strong sealing, cheap, etc.. Pipe connector retains the characteristics of the flange while the deficiencies have been improved, the shell as a whole also uses a more durable stainless steel, so what are the characteristics of the pipe connector?
 
Easy to install, small size, narrow space harsh conditions can also quickly complete the installation.
 
No need for any processing of the pipe section, directly connected.
 
Compared with the traditional flange is 79% lighter more convenient to carry.
 
Strong and corrosion resistant, no welding required, suitable for all kinds of pipes.
 
Allows the installation pipe to be offset, and the connection can be completed for the pipe with slight angle offset.
 
Vibration and noise reduction effect is obvious
 
Easy to install, only a hexagonal wrench is needed to complete the installation
 
Good sealing performance, reusable.
