AC-14 Anchor Casting Steel Material Stockless Hall HHP with High Holding Power for Cargo Ships

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 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:

AC - 14 anchor is the second-generation rodless large-holding force anchor (HHP). Its core advantages lie in high holding weight ratio, lightweight design, user-friendly operation, full compliance with classification societies, and wide applicability to large commercial ships and marine engineering. It is the preferred bow anchor recognized by the global mainstream classification societies.
1. Core advantages (technology and usage value)
Superior holding force and weight efficiency
Wide anchor crown + thick and long anchor claws + longitudinal strengthening ribs design, with a holding weight ratio of 8–14 (more than twice that of ordinary rodless anchors), capable of embedding deeply in soft mud, clay, and sandy seabeds, and providing strong stability.
Under the same holding force, it weighs approximately 25% less than traditional anchors, reducing the load on the anchoring equipment, saving deck space and anchor chain usage.
Reliable and durable structure
Integrated casting, key parts with strengthened ribs, subjected to normalizing / quenching heat treatment, with excellent tensile and impact resistance, without welding fatigue risks.
Hot-dip galvanizing (≥85μm) or heavy-duty anti-corrosion coating, with a salt spray environment lifespan of 15–20 years, long maintenance intervals.
Convenient and safe operation
No cross-bar design, the anchor claws automatically flip upward when retrieving the anchor, compatible with anchor chain tubes, capable of being completed by a single person for casting and retrieval, increasing operation efficiency by 30%+, avoiding hull scraping.
The anchor claws turn and sink into the seabed immediately upon touching the bottom, less likely to loosen in strong winds and waves, with both claws synchronously buried, maintaining balance and stability.
Global compliance and adaptability
Certified by mainstream classification societies such as ABS, DNV, LR, CCS, etc., in line with IACS and CB/T 3972 standards, suitable for international shipping vessels.
Specifications cover 56kg–20t, suitable for various large vessels such as ultra-large container ships, oil tankers, and bulk carriers.
