Copper nickel 90/10 pipe

January 31, 20230

What are characteristics of Copper nickel 90/10 pipe? (130)

CuNi 90/10 pipe, is a composite of 90% copper and 10% nickel. This material is known for its excellent corrosion resistance, making it an ideal choice for use in seawater applications and other corrosive environments. Copper nickel 90/10 pipe has the strength to withstand high pressures and temperatures while still providing the needed flexibility to absorb stress.

This alloy is also highly resistant to erosion, pitting, and crevice corrosion, giving it superior performance when exposed to extreme temperatures. Its malleability also makes it easier to install than other piping materials. Additionally, copper-nickel offers a smooth interior surface with less friction for fluid flow compared to galvanized steel and cast iron. This reduced friction can reduce energy costs over time by decreasing pressure losses associated with long-distance pumping systems.

Where Copper nickel 90/10 pipe used? (135)

This pipe is most commonly used in applications involving salt or brackish water. It is resistant to erosion and corrosion from seawater, making it an ideal choice for projects near oceans, rivers, lakes, bays, and other marine environments. It is also widely used for cooling-water piping systems at nuclear power plants due to its strength and resistance to oxidation and radiation damage. The alloy has a high strength-to-weight ratio, allowing designers to install thinner walls while still maintaining system integrity.

Additionally, the seamless nature of the pipe reduces potential leak points during installations to prevent environmental pollution and potential hazardous accidents. As a result of its overall durability and versatile applications, these pipes have become a popular choice in a wide range of industries ranging from offshore oil and gas extraction operations to shipbuilding activities.

What is EFW in piping? (147)

EFW stands for Electric Fusion Welding, a type of pipe welding process that is used in many industries to join pipes. This type of welding process uses an electric arc to heat the material which then melts it, allowing the pieces to be fused. It is most commonly used in high-pressure applications, such as those found in the oil and gas industry, where superior joint strength is needed.

This welding technique has become popular due to its fast speed and accuracy when joining large amounts of pipe quickly. The cost savings achieved by EFW makes it an attractive option for many companies as well. In addition, because it does not require skilled labour or preheating, there are fewer steps involved compared with other types of welding. As a result, this makes EFW an excellent choice for large-scale projects or where there is limited access to trained welders.

Does EFW pipe have a seam? (146)

Yes, the pipe does have a seam. It is made of an inner tube and an outer casing that are welded together along a longitudinal seam. This allows for the construction of larger pipes and higher pressure capabilities than with seamless pipes. The inner tube and outer casing of an EFW pipe are usually made of different materials which are joined together by the longitudinal weld seam to form a continuous surface. The strength and integrity of the joint between these two materials is essential in ensuring that the pipe can withstand its intended service conditions.

This type of pipe is designed to withstand extreme temperatures, pressures, and loads, as well as corrosion, abrasion, and erosion due to natural forces such as water or soil movement. Additionally, this welding technique results in a clean finish without sharp edges, eliminating potential hazards to people working around it.

Can I import Copper nickel 90/10 pipe without a broker in Saudi Arabia? (133)

No, you cannot import this pipe without a broker in Saudi Arabia. According to Saudi Customs regulations, all imported goods must be handled by a customs broker licensed by the Ministry of Commerce and Investment (MCI). A customs broker can assist in preparing the necessary documents, filing duties and taxes on behalf of the importer, and submitting them to Saudi Customs.

Additionally, there are specific documents that are required to legally import products into Saudi Arabia, including an invoice from the exporter, an original bill of lading from the carrier, a certificate of origin from the exporting country, and health or safety certificates for certain goods. These must all be presented when clearing customs. In conclusion, it is not possible to import the pipe into Saudi Arabia without hiring a licensed customs broker.
