Diver Magnet - 400
Diver Magnet – 400 er en kraftig tvillingmagnet for undervannsbruk bygd for større offshorearbeid. Den kombinerer to 78 mm neodym-grytemagneter (kjernen fra Diver Magnet – 200, kvalitet N45) under ett håndtak, og gir en nominell holdekraft på 400 kg og høy glidemotstand for arbeid på rørledninger, stigerør og konstruksjoner i sterk strøm. Hver magnet er forseglet i epoksy og HDPE for kontinuerlig bruk i saltvann. Enheten har en M10-øyemutter i rustfritt stål 316 for verktøy og liner, og et håndtak i rustfritt stål for fast plassering og god vektstangeffekt for kontrollert frigjøring av magnetene ved full holdekraft. Et posisjonerings- og holdeverktøy for profesjonelle dykkere – ikke løfteutstyr.
Holdekraft: 400 kg · Magnetflate Ø: 2 × 78 mm · Magnetkvalitet: N45 · Belegg: Epoxy-HDPE · Dybde: utprøvd i drift ned til 150 m · Opprinnelsesland: Sør-Afrika
The Diver Magnet - 400 is an industrial-strength neodymium pot magnet rated at 400 kg pull force — built for the most demanding subsea applications including a secure anchor point for divers, large-diameter pipeline work, and offshore construction tasks. Manufactured by Diving Magnets (Pty) Ltd in South Africa with Epoxy-HDPE coating for corrosion resistance and 316 stainless steel hardware, this diver magnet is trusted by commercial diving professionals worldwide.
Hva brukes Diver Magnet - 400 til?
- Heavy-duty diver positioning on major subsea construction
- Large-diameter pipeline inspection and repair operations
- Offshore decommissioning and structural cutting support
- Magnetic anchor point and equipment staging on subsea structures
- Hull inspection and cleaning on large commercial vessels
Egenskaper og fordeler
- 400 kg rated pull force — maximum holding for the most demanding subsea tasks
- Magnet sealed in epoxy and HDPE for continuous saltwater use
- 316 stainless steel eye nut, handle and screws — engineered for extreme marine environments
- Built for offshore construction, decommissioning, and pipeline work
Hvilke overflater fungerer Diver Magnet - 400 på?
Fungerer best på
- Mild steel and carbon steel (best performance — flat, clean surfaces)
- Cast iron structures and components
- Structural steel beams, columns, and plate
- Steel pipelines and risers
- Ship hulls and marine vessel steel
Reduserer ytelse
- Rusted or corroded surfaces — rust and scale create an air gap that reduces pull force
- Painted or coated surfaces — coating thickness creates an air gap
- Curved surfaces — reduced contact area lowers effective pull
- Thin metal (under 5 mm) — insufficient material for full flux path
Fungerer ikke på
- Aluminium, brass, copper, and bronze (non-ferrous metals)
- Most austenitic stainless steels (304, 316) — little or no attraction, slightly magnetic only where cold-worked or welded
- Concrete, wood, plastic, fibreglass, and composites
- Titanium and non-magnetic alloys
Sikkerhetsretningslinjer
- Always wear protective gloves when handling magnets rated above 100 kg pull force — pinch injuries are the most common hazard
- Keep magnets away from dive computers, compasses, and electronic instruments — strong magnetic fields can cause permanent damage
- Never allow two magnets to snap together uncontrolled — the collision force can shatter the magnet and cause flying debris
- Use a safety lanyard to secure the magnet to your harness — prevents loss in current or during detachment
- Attach at a 45° angle and rotate flat — never approach a steel surface head-on with a strong magnet
- Brief your dive team on magnet location — unexpected strong pull near steel structures can trap equipment or limbs
Vedlikehold og stell
- Rinse thoroughly with fresh water after every saltwater use — salt crystals accelerate corrosion if left on the coating
- Dry completely before storage — moisture trapped against the magnet surface causes coating breakdown over time
- Inspect the Epoxy-HDPE coating regularly — any chips or cracks expose the neodymium core to corrosion
- Remove iron filings and metal particles after each use with a wire brush or cloth — accumulated debris reduces pull force
- Store in a cool, dry environment away from electronic equipment — temperatures above 80°C permanently reduce magnetic strength
- Apply a thin layer of corrosion inhibitor (light oil or silicone spray) for long-term storage
Maximum holding power for industrial subsea work
- Large-scale offshore construction and decommissioning operations
- Tasks requiring 400 kg pull force for the heaviest subsea tools and equipment
- Saturation diving operations where equipment staging is critical
- Companies that need maximum holding force from high-grade N42–N48 cores — grade for grade, an N48 core stores about 14% more magnetic energy than an N42 core of the same size
- Projects where magnet failure would create serious safety or operational risk
