Copper Nickel Flanges Production Process

If you want to know the steps to make a copper-nickel flange, here’s a video you’ll want to turn on and watch.

Cutting Material

Inspection of copper nickel rods results in a pass. Saw to the required size with a sawing machine.

 Forging

The shape of the flange is forged. Forging is the process of removing impurities and porosity from the bar.

Heat Treatment

The forged flange blank must be annealed. The annealing temperature is 800 to 900 degrees Celsius, holding for 30 minutes.

CNC Machining

We have 10 CNC machines. We can make all forms of copper-nickel flanges. Among them, there are too big machine tools that can process flanges up to 700mm outer diameter.Welcome your enquiry.

Copper Nickel Flanges: Your Comprehensive Guide

Table of Contents

What is the classification of copper nickel flanges?

Our copper nickel flanges adhere to the European standard, utilizing materials such as CuNi10Fe1.6Mn, CuNi90/10, CuNi70/30, and UNS C7060X.

Your copper nickel flange standard is the American standard. Then the material is C70600 and C71500.

If the standard is the British standard Bs2871, the material is Cn102. 

What varieties of copper nickel flanges are available?

 The range includes copper-nickel weld neck flanges, inner flanges (also known as stub end flanges), fillet weld flanges, slip-on flanges, socket weld flanges, blind flanges, and threaded flanges.

Do you manufacture copper nickel flanges?

copper nickel fitting Manufacturer

 Yes, we specialize in the production of copper nickel flanges and are based in China.

If you are looking for copper nickel flanges, you can trust me.

We have 20 years of experience in manufacturing copper nickel flanges.

How to choose a flange surface waterline?

Three general types of copper nickel flange surface waterlines are smooth, grooved, and delicate threaded.

In our experience, customers generally choose the grooved surface waterline.

Some European customers choose the fine-threaded surface waterline. There is little difference between the grooved and threaded surface waterline.

The rubber gasket is placed in the middle to seal the connection and slips in the smooth side of the flange.

Therefore, our customers choose the smooth surface waterline less often.

What are the advantages of your company ?

copper nicekel flange faq

Other companies only produce flanges up to the largest of 419mm because we have a large lathe.

We can make flanges up to the largest of 710mm for you.

Our warehouse has copper nickel rods from DN 20 to DN 200. Your flange raw materials are in stock in our warehouse.

We forged Flange blanks near our company.

We can produce copper nickel flanges in about 30 days,other companies deliver slower than we do.

What standards to the production of copper nickel flanges?

We have been making copper-nickel flanges for 20 years.

According to our previous experience. It would be best, if you had a copper nickel inner flange using DIN86037 and EEMUA234 standards.

 The standards used for copper nickel high-neck flanges are EEMUA234, JIS B2220 and ANSI B16.5.

Copper Nickel Slip-On Flanges are typically produced by standards such as EEMUA234, and ASME B16.5.

What are the pressure ratings of copper nickel flanges?

Copper-nickel flanges come in various pressure ratings including 10 bar, 16 bar, 20 bar, 150 class, and 300 class.

The pressure ratings for copper-nickel flanges differ based on the type of steel used.

The pressure rating of steel flanges is excellent, and the copper nickel flanges are less.
