Cast iron protective pipes for optical cables, such as Protectorshell Split Pipe and UTS Cable Articulated Split Pipe, provide robust mechanical and corrosion-resistant protection for subsea, offshore, and terrestrial fiber optic installations.

Protectorshell Split Pipe

Material and Construction: Protectorshell Split Pipe is manufactured from ductile iron, which combines the corrosion resistance of traditional cast iron with enhanced strength. The split pipe design allows for easy installation and recovery in water depths up to 100 meters. Dimensions and Models: Available in inner diameters from 55 mm to 260 mm, with the possibility of custom sizes depending on project requirements.

Accessories include J-Tube Seals, Bend Restrictors, and Bend Stiffeners for offshore and subsea cable protection. Applications: Used for shore-ends, cable pipeline crossings, undersea cable protection, post-installation protection, and offshore wind cables. The system is suitable for both land and shallow water environments.

UT

S Cable 55 Articulated Split PipeMaterial and Design: Made from cast or ductile iron, the UTS Cable 55 Articulated Split Pipe accommodates cables, umbilicals, and flexible pipelines up to 50 mm diameter. It features a self-locking hook and pin design, with optional stainless steel (316 grade) fixings for additional security. Mechanical Properties: Provides protection against abrasion, rock dumping, and maintains design bend radius over rough terrain and free spans.

Each batch undergoes rigorous testing for mechanical and chemical compliance according to ISO 1083. Packaging and Handling: Delivered in robust palletized wooden boxes treated to ISPM15 standards, ensuring safe transport and storage. Panduit URAPROTECT™ Subsea Protection SystemMaterial and Features: While not strictly cast iron, the Panduit system complements cast iron pipes by providing abrasion and impact resistance using marine-class polyurethane half shells.

The system is lightweight, easy to handle, and installed with corrosion-resistant metallic banding. Applications: Designed for subsea cable crossings, flexible flow lines, and offshore renewable energy installations. Includes bend restrictors to prevent over-bending during installation and service.
