ASTM B151 UNS C71500 Slip On Flange and Cu Ni 70/30 Blind Flange suppliers in UAE

What is Copper Nickel 70/30 Flange?
A 70/30 copper nickel flange is designed with 70% copper and 30% nickel content. Copper nickel 70/30 flange also has small additions of manganese and iron that help to strengthen it. The flanges help in efficiently connecting different piping equipment in the system. The head of the 70/30 copper nickel flanges acts as a rim or lip. This lip provides support to different equipment while connecting them. The Cu Ni 70/30 blind flange has a density of 8.94 g/cm3 with a melting point of 2140°F. These flanges have excellent performance in sweater systems.
What is ASME B16.5 Class 150 UNS C71500 Flange?
The ASTM B151 UNS C71500 class 150 is a pressure class of the flange. This pressure class is generally designed to hold lower pressure media. As the temperature increases the pressure rating of the UNS C71500 slip on flange decreases. Generally, the flange is rated at 270 PSIG under ambient conditions. It decreases to 180 PSIG at approximately 400°F as the temperature rises.
Difference between 70/30 Copper Nickel Flanges cut, cast, and forging manufacturing methods
Flanges can be manufactured in different processes, and below are some common methods.
- A copper nickel 70/30 weld neck flange cut method begins by flattening the metal using rollers until it reaches the intended thickness. The flange is then cut into appropriate outside and inner diameters which have no center bore. Bolt holes and serrations are then cut in the 70/30 copper nickel lapped joint flange . These flanges have a lower production cost.
- A cast 2.0882 cuni lap joint flange is formed as molten metal is poured into a mould of the desired shape. After the liquid is hardened the mould is opened. The cast 70/30 cupro nickel threaded flange costs less to produce and is easily machined.
- In the forging process heat billets and other metal stock are used. The DIN 2.0882 forged flange is then compressed using a hammer or die to shape it in a solid state. The process develops a continuous grain flow and has improved strength.
What is serration process? Are C71500 flat face flanges serrated?
The serration process of a C71500 copper nickel inner flange make use of a saw like device having tooth like projections. During this process, the saw is run over the steel to create groves or serrations on the surface. A flat face Cupro Nickel 70/30 socket weld flange can be serrated to enhance its appearance and performance.

What is smooth finish ASTM B151 UNS C71500 Flange?
A smooth finish C71500 flange has a shiny smooth appearance. These flanges don’t have any markings of a tool on them. The smooth finish on the 70-30 Cu-Ni reducing flange is achieved by having the contact surface machined with a spiral groove. They are more common for low pressure and larger diameter pipelines.
