Nodular Cast Iron Articulated Pipe

Ductile iron articulated pipe consists of two identical half shells of self-locking articulated pipe. The protective shell articulated pipe is made of ductile iron, which enhances the corrosion resistance of traditional cast iron. It is a simple and cost-effective cable protection system.

Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, which are expensive and highly confidential. Submarine power cables are mainly used for underwater transmission of high-power electrical energy.

Underwater cables, which carry the vast majority of intercontinental communications, are hidden in the deep sea and play a vital role in our lives, even though they are invisible to us. But submarine cables are fragile and can be broken or damaged by water pressure, fish such as sharks, ship anchors, trawls or other environmental factors.
Therefore, subsea cable protection casing needs to be designed and constructed as an additional protection to make the cable sufficiently durable and reliable.Submarine cable protection pipe is essential for every offshore project.。Articulated pipe cable protection are connected with a spherical hinge structure.Multiple sleeves are connected by spherical hing joints, and each section can be flexibly twisted.

When an earthquake or sea occurs on the seabed when the bed changes and is impacted by an external force, due to the spherical hinge structure connection between the protective tubes, the shock or impact energy is absorbed during the buffering process, and the shock resistance and impact performance are increased, which can effectively protect the cables and optical cables from vibration or impact damage.
Our cast iron articulated pipe casing is made of high quality ductile iron as the main raw material, adding some special metal components and processing on a specific process.

Spherical graphite is obtained by spheroidizing and inoculating treatment of ductile iron, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than carbon steel.
Ductile iron pipe, it is based on its excellent properties that it has been successfully used to cast some parts with complex force, high strength, toughness and wear resistance.Ductile iron has rapidly developed into a widely used cast iron material second only to gray cast iron.
The articulated pipe is unique in that it clips together, this clip- together feature allows quick real-time application during laying and a much simplified diver installation onto pre-laid cables.
The submarine cable articulated pipe comprises two different cast segments which are identified as uppers and lowers.Each successive pair of segments clips over and retains the end of the preceding pair.

The Cable Protection System has been designed as a simple and cost effective cable protection system for areas where conventional burial or trenching methods prove to be uneconomical and/or not achievable due to bottom conditions.

Thed nodular cast iron articulated pipe are designed in-house and are subject to rigorous quality and durability testing to ensure the highest quality and durability.

Ductile cast iron cable protection system used for:

Protection of Power Cables\Protection of Telecom Cables\Protection of Optical Cable\Protection of Water Pipes\Typical installation locations include but are not limited to shore end, subsea crossings and areas with extreme environmental conditions, such as areas with rock formations, coral reefs and coastlines which are subject to severe erosion.
