Australian / New Zealand Regulations for Pressure Vessels - Part 2

Dive deeper into hydraulic pneumatic accumulators, with a focus on compliance with Australian regulations.

The Importance of Proper Documentation

Proper documentation is essential when it comes to ensuring that hydraulic pneumatic accumulators meet all necessary regulatory requirements in Australia. Here's why it matters:

• Regulatory Compliance: Maintaining detailed records ensures that all legal and safety standards are met, including design approvals, plant registrations, and manufacturer certifications.
• Audit Preparedness: Having thorough documentation ready can help avoid penalties or operational disruptions during inspections by agencies like WorkSafe.
• Maintenance Tracking: Keeping accurate inspection logs helps monitor the condition of accumulators over time, supporting proactive maintenance and identifying potential issues early.
• Risk Management: Documenting risk assessments and inspection plans allows for more flexible and efficient maintenance strategies, as recommended by AS3788.

 

Key Documentation You Need

1. Design and Registration Papers: These include engineering drawings, calculation sheets, and certificates confirming the accumulator’s suitability for its intended use.
2. Manufacturer Reports: These provide details about materials used, pressure ratings, and performance limits, offering critical insights into the unit's reliability.
3. Inspection Records: From initial commissioning checks to ongoing periodic reviews, these documents ensure that the accumulator remains safe and compliant throughout its lifecycle.

 

Understanding Inspection Regimes for Safety

AS3788 outlines strict inspection regimes to maintain the integrity and safety of hydraulic pneumatic accumulators. Key types include:

• Commissioning Inspections: Conducted before the accumulator is put into service, these verify structural integrity and confirm that the unit is suitable for its intended application.
• Regular Maintenance Checks: Depending on usage and environmental conditions, these inspections ensure the system continues to meet safety standards over time.
• Specialized Assessments: Performed after incidents, repairs, or changes in operating conditions, these evaluations help identify any hidden risks or damage.
• Internal vs. External Inspections: While internal checks are more involved and costly, they are crucial for detecting corrosion or structural weaknesses that may not be visible externally.

 

Adopting Risk-Based Inspection Strategies

Frequent inspections can be time-consuming and expensive. A risk-based approach, as outlined in AS3788, allows for more strategic planning. By conducting thorough risk assessments and engaging with stakeholders, companies can adjust inspection schedules without compromising safety or compliance.

PVD Coated Screw

PVD (Physical vapor deposition) is characterized by a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase. We are using this technology on our Titanium nitride coated screws.

HVOF (High Velocity Oxygen Fuel) coating process is a kind of thermal spraying technique that melted (or heated) materials are sprayed into the surface. By HVOF technology, alloy powder spraying is under high pressure and high velocity. The adhesive force is over 10000PSI, and the powder density can be achieved up to 99.8%, which offers outstanding performance in wear & corrosion resistance.

Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Such screws are mainly to be used for the corrosive and other free flow material.
