CuNi pipe is a type of pipe made from a copper-nickel alloy, which offers excellent resistance to corrosion, erosion, and biofouling. These properties make CuNi pipes an ideal choice for use in shipbuilding and marine applications.
If you are working with us for the first time, we will send you a video of our factory and warehouse . To prove that we are a genuine manufacturer. We have certificates from classification societies to send you, proving that we are a competent manufacturer. We are a CuNi pipe manufacturer, you don’t have to worry, we will work well with you to complete your project.
The most common CuNi for pipelines is CuNi 90/10 (90% copper, 10% nickel) and CuNi 70/30 (70% copper, 30% nickel). The most commonly used is CuNi 90/10.
This is because manufacturers of cuni pipes stock the dimensions and wall thicknesses specified in the standards. If you choose an outer diameter that is not standard, the manufacturing time and cost will greatly increase.
Accessories welded to non-standard cuni pipes will also have to be re-moulded, and the accessories will be very expensive to produce and have a long lead time. You should choose the standard specified outer diameter and wall thickness.
The pricing of our CuNi pipes depends on factors such as the specific alloy composition, dimensions, standards, order quantity, and market fluctuations in raw material costs. We strive to offer competitive pricing without compromising on quality.
We adhere to strict quality control procedures throughout the entire production process, from raw material selection to final inspection. Our pipes are manufactured in compliance with international standards, and we can provide material test reports, certificates of conformity, and other relevant documentation to demonstrate compliance with industry requirements.
We utilize advanced equipment and measuring tools to precisely control the dimensions of our CuNi pipes during production. Each pipe is inspected and measured to ensure that the wall thickness and outer diameter are within the tolerances specified by the relevant standards.
As a leading CuNi pipe manufacturer, we offer high-quality pipes at competitive prices, ensuring that you can provide your clients with reliable products while maintaining profitability. We also provide excellent customer service, technical support, and prompt delivery to help you meet your clients’ requirements and expectations.
CuNi pipes exhibit excellent resistance to stress corrosion cracking and fatigue due to their ductility and corrosion-resistant properties. This makes them ideal for applications where constant exposure to harsh marine environments and dynamic loads are expected.
