Hot Dip Galvanized HHP Stockless Anchor High Holding Power Marine Anchor (AC-14 / HHP type available)

Product Description:

Material Advantages:

Stable pulling force: On regular seabeds (sand, mud), the pulling force performance is reliable, meeting the daily anchoring needs of merchant ships, with high cost-effectiveness.
Easy operation: The absence of cross-bar design simplifies the retraction, storage and reassembly process, reducing the operational intensity of crew members and improving work efficiency.
Low maintenance cost: The cast steel structure is sturdy and durable, with adequate surface protection treatment. Daily maintenance only requires regular inspection of accessories and surface coatings, making the maintenance simple.

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.

Features:

Stockless Design: No crossbar, easy to deploy, stow and retrieve.
Dual Fluids: Two flukes pivot and dig into seabed simultaneously for stable holding.
Strong Structure: Forged shank + cast steel crown, high strength and wear resistance.
Quick Setting: Tripping palms help flukes bury fast in mud, sand and mixed seabeds.
Space‑saving: Fits neatly into anchor pockets or against hull, saving deck space.
