Open Sea Aquaculture Fish Cages

HDPE Cage Description:                                                                     

Marine Aquaculture Fish cages are composed of HDPE pipes, double-hole brackets, Upright pipes, tees, stoppers, pins, and walkway padels as options. We can provide complete sets of products for on-site installation at customer facilities. The double-hole brackets are compatible with fish cage floating pipes ranging from 200mm to 500mm in diameter.

HDPE100 Pipes are an excellent material for cage construction because they are durable, flexible, shockproof, resistant to ultraviolet (UV) light and require relatively little maintenance, if installed correctly. The diameter of the pipes determines the buoyancy of the cage collar. The more buoyancy will be needed, the large pipe diameter will need. HDPE Brackets will be sized according to the pipe's diameter.

The main floating pipe consists of two HDPE pipes with a diameter(Φ) of ≥200mm, which are hot melt butt fusion welded into a fully enclosed circular ring. The inner and outer pipes are connected and fixed by HDPE I-shaped frames. The handrail pipe is made of one circular, hollow polyethylene plastic pipe, which is butt fusion welded into a circular ring.

The I-shaped frame is a one-piece structure formed by a double holes HDPE bracket, an upright pipe, and an equal-diameter tee butt fusion welded with upright pipe. The double-hole HDPE bracket is a special pipe fitting for anti-wind and wave cage frame, manufactured by mold pressure injection molding, with a minimum thickness of ≥20mm at its thinnest point. The I-shaped frames are evenly distributed along the perimeter of the cage frame, with a spacing of 1.5m to 2.0m.

Pins and Stoppers are provided as assembly accessories. Pins are used to secure the connection between the upright pipe and the bracket, as well as to fix the tee and the handrail pipe. Stoppers are thermally welded to both sides of the bracket to secure the bracket in place. Walkway pedals are provided as an option, depending on customer design.
