EEMUA 145 Blind Flange and C70600 flange suppliers in UAE
What is Copper Nickel 90/10 Flange?
A 90/10 copper nickel flange has a 90% chromium and 10% nickel content. The copper nickel 90/10 flange is strengthened by small additions of manganese and iron. These flanges exhibit superior strength and connect different piping equipment. The 90-10 cuni flanges have good corrosion resistance and stress corrosion cracking. These flanges have an inherent resistance to biofouling and have good tolerances.
The 90/10 copper nickel flanges work well across marine and saltwater environments. These flanges are tolerant to pitting by acids that are common in seawater conditions. A cupro nickel 90/10 flange has enhanced toughness, ductility and can be readily welded following standard welding procedures.
The Cu-Ni 90-10 welding neck collar has a minimum tensile strength of 280mpa with a minimum yield strength of 105mpa. It can be elongated by 27% in the system. A cupro nickel 90/10 blind flange maintains these properties even at cryogenic temperatures. These flanges have a hardness between 70 to 120HB max.
A copper nickel 90/10 socket weld flange is designed in pressure classes between 150# to 2500#. These flanges have schedules ranging between SCH 10 to SCH 160 and XXS. The Cu Ni 90/10 reducing flange can be hot rolled or cold drawn and polished with a specific surface finish.
The 90-10 Cu-Ni slip on flange is one of the most versatile flange types in this range. It is generally welded using one or more fillet welds. A 90/10 cupro nickel weld neck flange is commonly seen in offshore and marine systems and chemical processing units. The versatile 90/10 copper nickel forged flange is also a feature in condenser plates, pressure vessels, brake lines, etc.
How the serration on 7060x flange is specified? How do you test serration in EEMUA 145 Flange ?
The serration on the ASTM B151 UNS C70600 flange is specified on two parameters. This includes the Root Mean Square and the Arithmetic Average Rough Height. Generally, an EEMUA 145 flange h as a serrated face value between 120 to 250 Arithmetic Average Rough Height. The testing and measurement of EEMUA 145 flange can be done using visual and tactile means.
What is the difference between RF and DIN 86037 RTJ flange?
An RTJ DIN 86037 flange creates a metal-to-metal seal between two mating flanges. These flanges feature a circular grove and can accommodate the ring joint gasket. A DIN 86037 inner flange is designed to handle high pressure and temperature applications in temperatures above 700 degrees C.
A raised face DIN 86037 composite weld neck inner flange can be recognized by its gasket surface. The gasket surface of these flanges is raised above the bolting area. This allows the UNS C70600 RTJ flange to be securely sealed in the system.
Difference between ASTM B151 UNS C70600 flange rating vs design pressure
The pressure rating of NS 7060x threaded flange can be referred to as the pressure holding capacity of a flange. The design pressure is the pressure a specific flange design can withstand.
