Accurately marking the position of buried utilities such as water mains, gas pipelines, fibre optic cables, and electric lines is essential for safety, compliance, and operational efficiency. While general marker plates provide surface-level identification, underground networks often require specialised marker posts and plates that remain visible, durable, and accurate in the field.

This guide explains the role of underground utility marker posts and plates, the best materials for long-term durability, typical cost ranges, and how they help protect vital infrastructure.

Air release valves are essential to the safe and efficient operation of petrochemical pipelines—especially where seawater is used for firefighting systems. These valves help eliminate trapped air, preventing flow disruption, pressure surges, and premature equipment wear.
However, like any mechanical component in a harsh industrial environment, air release valves can experience operational issues over time. When they malfunction, the consequences can range from minor performance drops to serious system failures.
This guide is designed to help operators and maintenance personnel quickly identify and resolve the most common problems encountered with air release valves in petrochemical applications.

In petrochemical systems, where precision, safety, and uptime are critical, air release valves serve a deceptively simple yet essential function. Though often small in size, these components protect entire pipeline networks from inefficiencies, structural damage, and catastrophic failures caused by trapped air.

Choosing the Right Materials in Petrochemical Valve Design
When it comes to petrochemical processing, even the smallest component can make or break the safety and efficiency of the entire system. Air release valves, while often overlooked, play a critical role in removing trapped air that can otherwise cause pressure fluctuations, flow disruption, and premature wear. However, due to the highly corrosive and chemically aggressive nature of petrochemical environments, not just any valve material will do.
