Copper Nickel 90/10 Pipe fittings

Copper nickel 90/10 pipe fittings specifications

What are Copper Nickel 90/10 Pipe fittings/ Buttweld Fittings?

These corrosion-resistant products comprise 90% copper and 10% nickel with iron and manganese. Copper nickel 90/10 pipe fittings operate extensively in marine industries due to their stress corrosion cracking (SCC) resistance in chloride environments.

Copper nickel 90/10 buttweld fittings are suited to severe temperatures in chemical processing, instrument resistors, and petrochemicals.

What are the most common applications of Copper Nickel 90/10 Pipe fittings?

The most widespread use of 90/10 copper nickel pipe fittings is in the marine sector for offshore fire systems, harbour installations, shipbuilding, and coastal power stations.

A copper nickel 90/10 elbow works in condensers, heat exchangers, and air conditioning – thanks to high-temperature tolerance and thermal conductivity.

We believe that using the right testing methods is crucial to supplying ASTM B466 UNS c70600 tee and Cu-Ni 90/10 end cap that meet the highest quality standards and deliver reliable performance

How does Manifest Alloys ensure the reliability of the testing methods used for Copper Nickel 90/10 Pipe fittings?

Quality testing of a DIN 2.0872 short radius elbow involves hardness and tensile strength assessments and a Charpy Impact test. We also use Positive Material Identification, ultrasonic testing, radiography, and Liquid Dye Penetrant testing (NDT approaches).

Our examination methods for a UNS C70600 stub end are internationally standardised. Manifest Alloys has in-house expertise and advanced infrastructural capabilities for accurate, repeatable results.

We are pleased to offer DIN 2.0872 short radius elbow and 90/10 copper nickel reducer that have been crafted to the highest standards, exhibiting remarkable resistance to heat and pressure

How do Copper Nickel 90/10 Pipe fittings compare to other materials in corrosion resistance?

A 90/10 cu-ni end cap stands up against seawater, organic acids, sulfuric acid, alkalis, and macrofouling with a corrosion rate of 0.025mm/year. It is much more resilient to pitting, crevice corrosion, and SCC than stainless steel or aluminium.

However, it struggles amid pollutants like ammonia and sulfides – situations where super duplex grades can be better choices.

More information on the surface finish and dimensional tolerance of UNS c70600 stub end and CUNI 90-10 reducer can be found by reading technical datasheets

Can technical datasheets for Copper Nickel 90/10 Pipe fittings be customised according to customer requirements?

We stock elbows, ASTM B466 UNS C70600 tee, and caps in multiple dimensions. Contemporary production facilities help us adapt technical datasheets to buyer specifications.

For example, we can deliver a C70600 copper reducer in ½ to 12 inches or tailored sizes and metallurgical characteristics.
