CF4000 with inner ring
Description:
CF4000 with inner ring is mainly installed on flanged couplings male-female type according to ASME B16.20 or EN 1514-2 standards.The internal containment ring increases the degree of resistance to the blow out effect (coming out of the flanges).
They can be installed on high pressure lines and appliances.
- Ideal for the oil & gas industry
- Excellent mechanical behavior even at high temperatures and pressures
- Wide choice of structural conformations, types of alloys and fillers
