Product qualities:
Cupro Nickel Flanges have a lot more to offers effective resistance to marine water, organic compounds, diluting non-oxidizing acids, and many more. Because of the resistance to marine water, these flanges are best for application in seawater piping systems. They offer excellent resistance to sea water, non-oxidizing acid corrosion, and atmospheric conditions. The combination of nickel and copper improves the overall potency of corrosion resistance in the product.


Quality assurance:
We always try to ensure the faultless of these Cupro Nickel Flanges. Products are being tested at each stage. Our quality inspectors and efficient team workers contribute to the efficiency of our quality system. Our team holds expert knowledge in industry standards and latest inspection equipment and machinery to meet all requirements.


Positive material identification, flattering test, micro test, micro test, flaring test, pitting resistance test, spectro analysis test, and many more are conducted to test the quality of the product. All the tests are conducted by the industry to assure the quality of the product.


Packing and transportation:
Just to ensure that there is no damage is caused to the product while transportation packaging is done. Packing ensures that zero - defect goods are delivered to our customer. We ensure that the packing of goods is done in wooden boxes, plywood cases, pallets, etc. packaging may differ according to the product.


Thus, Cupro Nickel Flanges plays a vital role in the most corrosive conditions by preventing oxidization and erosion.
