Flare Flanges

Flare is the tube forming technology for hydraulic pipe and tube assembly, it has a 37 degree flared tube end, assembly with flange connection system according to ISO 6162-1 SAE J 518 bore 4 holes pattern 3000 (code 61); ISO 6162-2 bore 4 holes pattern 6000 (code 62) and ISO 6164 bore 4 holes pattern. It is a non-welded seamless piping connection system.

Definition of Flare Flanges:

Flare is the tube forming technology for hydraulic pipe and tube assembly, it has a 37 degree flared tube end, assembly with flange connection system according to ISO 6162-1 SAE J 518 bore 4 holes pattern 3000 (code 61); ISO 6162-2 bore 4 holes pattern 6000 (code 62) and ISO 6164 bore 4 holes pattern. It is a non-welded seamless piping connection system. 


Advantage of 37 flare flange:

● Ideal replacement for welded piping systems in marine, shipbuilding, industrial&offshore.

● Designed for low to high pressure pipe/tube connection.

● Time saving for welding and assembly time, tube cleaning, inspection and x-ray test. 

● Easy to assembly and re-assembly many times.
