Copper Nickel 90/10 Flange

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.

How much pressure can a Class 300 C70600 flange take?

A class 300  C70600 flange  is designed with moderate strength and tolerance. Generally, a class 300 flange is designed to handle 570  psi  at temperatures of 600 degrees F. As the temperature in the  7060x flange  increases its  pressure holding capacity decreases.
