Product Introduction

DESCRIPTION

WQTF ductile cast iron glass fiber double composite articulated pipe can effectively protect submarine power cables and optical cables, and avoid external mechanical damage and damage to cables and optical cables. Because WQTF double-layer joint casing has simple structure, convenient construction, high strength, and corrosion resistance, it has widely replaced traditional submarine cable protection tubes composed of pure metal materials, and is used in submarine cables and optical cable protection and transformation projects.

FEATURES

1. Scientific appearance and structure

The shape structure of WQTF ductile cast iron glass fiber double composite articulated pipe is specially designed to increase the adhesion to the seabed. The Huff spherical hinge structure makes the protective tube and the protected submarine cable or optical cable firmly adhere to the seabed, in the rocks and gravel, and is not easy to be affected by the submarine ocean currents. Tidal reciprocating push friction rolling and damage; Huff spherical hinge connection, the maximum angle of the two connected protection pipes can reach 25°, and can rotate freely in all directions, which can effectively prevent the submarine cable from twisting or the bending radius is too small to cause the submarine cable Damaged insulation layer structure.

2.Strong seismic and impact resistance

WQTF ductile cast iron glass fiber double composite articulated pipes are connected with a spherical hinge structure, using the principle of bionics, and imitating the connection structure of human joints. Multiple sleeves are connected by spherical hinge 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.

3. Corrosion resistant, economical and environmentally friendly

WQTF ductile cast iron glass fiber double composite articulated pipe has been treated with special anti-corrosion paint, and the inner glass fiber reinforced composite layer is economical and environmentally friendly, not easy to be corroded by sea water, not easy to rot, and has a long protection period.
