Product Description:

Material Advantages:

High Holding Power Design
Features large flat flukes with sharpened tips/inner edges for rapid seabed penetration, and a reinforced crown plate to prevent over-penetration. The optimized fluke-to-shank ratio ensures stable holding even in strong currents and rough seas, with a holding power-to-weight ratio 2–3x higher than conventional stockless anchors.
Fully Balanced Configuration
The fully balanced model keeps flukes upright during retrieval, avoiding jams in anchor pockets and simplifying stowage/deployment. A 10% shortened shank option is available for vessels with limited deck space.
Durable Construction
Welded from high-tensile steel with strict quality control (NDT testing for weld integrity). Corrosion-resistant surface treatments ensure long-term performance in saltwater environments, reducing maintenance costs.
Certified Compliance
Each anchor comes with original classification society certificates, meeting IMO MSC.86(70) and IACS UR W2 standards, ensuring global regulatory compliance for marine operations.

Manufacturing Process:

The production process of Admiralty Anchors strictly adheres to marine anchor casting standards and offshore mooring equipment strength requirements, centered on “structural precision, material strength and toughness, and corrosion resistance compliance.” Specific steps are as follows:

### 1. Raw Material Preparation and Mold Design
- Select high-strength cast steel (ZG230-450) or premium marine carbon steel. Ingredients are blended according to chemical composition requirements to ensure compliance with carbon, manganese, and other elemental content standards, enhancing tensile strength and toughness.
- Design sand molds based on anchor specifications (weights ranging from 500kg to 50t). The mold cavity precisely replicates the naval anchor's “four-fluke crown + crossbar” structure. Thickened sections are incorporated at the anchor fluke-to-shank junctions. Mold inner walls undergo polishing to prevent surface defects in castings.

### 2. Monolithic Casting
- Molten cast steel (1500-1600°C) is injected into the mold via a pouring system using gravity casting. This ensures uniform filling without dead zones or porosity.
- After natural cooling to room temperature, the mold is opened to remove the anchor blank. Gates, risers, flash, and other excess material are trimmed to prevent residual stress-induced cracking.

### 3. Structural Reinforcement and Precision Machining
- Critical load-bearing areas like anchor claws and crown undergo forging reinforcement to enhance localized hardness and impact resistance. Claw edges are ground to ensure sharpness and improve seabed gripping efficiency.
- Machine the connection hole at the top of the anchor body (to match anchor chain specifications). Bore the hole walls smooth to ensure secure chain attachment. Secure the crossbar via welding or integral casting. Apply full-penetration welding at joints and perform non-destructive testing.

### 4. Surface Anti-Corrosion Treatment
- Perform sandblasting rust removal first to thoroughly eliminate surface scale, rust, and oil contamination, achieving Sa2.5 standard to enhance coating adhesion.
- Apply a dual-layer coating of “epoxy zinc-rich primer + marine-grade topcoat” (total thickness ≥150μm) or utilize hot-dip galvanizing (zinc coating thickness ≥85μm). Both methods effectively resist offshore seawater corrosion and salt spray erosion.

### 5. Finished Product Inspection and Quality Control
- Visual Inspection: Verify anchor body is free of cracks, pores, pinholes, or other defects. Structural dimensional deviation ≤ ±3%. Anchor fluke symmetry and crossbar verticality meet design requirements.
- Performance Testing: Conduct tensile strength testing (≥400MPa) and impact toughness testing. Perform simulated holding force tests on samples to verify holding force meets standards (≥8 times its own weight).
- Corrosion Resistance Testing: Pass salt spray testing (1000 hours continuous) to evaluate coating or galvanized layer durability, meeting offshore long-term service requirements.
- Compliance Certification: Products must obtain certification from classification societies such as CCS and ABS, ensuring compliance with GB/T 5468-2019 “General Technical Conditions for Marine Anchors” and offshore mooring equipment standards.

### 6. Packaging and Shipping
- Packaged securely on wooden pallets or steel frames to prevent deformation during transit. Anchor bodies are wrapped in moisture-proof film to protect anti-corrosion coatings.
- Includes product inspection reports, certification documents, and installation manuals for seamless offshore project integration or on-site deployment.
