高温作業における理想的なメカニカルシールサポートシステムの選択

In industries where process temperatures soar well above 150°C, choosing the right mechanical seal support system becomes a defining factor in system reliability, safety, and operational efficiency. Whether operating in power generation, petrochemicals, or heavy-duty manufacturing, engineers are constantly tasked with mitigating heat-related seal failures.

‍

Understanding High-Temperature Challenges

High-temperature environments pose several technical challenges for mechanical seals. Excessive heat can accelerate wear, degrade lubricants, and impact seal face materials. Without proper support, seals may fail prematurely, leading to unplanned downtime, higher maintenance costs, and safety risks.

To combat this, seal support systems play a pivotal role by providing necessary lubrication, cooling, and pressure regulation. Among these systems, API Plans 52, 53, and 54 are commonly used, each with distinct advantages based on application demands.

‍

API Plan 52: A Simpler Option for Moderate Conditions

API Plan 52 involves an unpressurised buffer fluid system. It is primarily used with dual unpressurised seals and relies on a reservoir to cool and lubricate the seal faces. While adequate for moderate temperatures and less aggressive processes, Plan 52 has limitations in high-temperature applications due to the lack of forced cooling.

‍

API Plan 53: Adding Pressurised Support

Moving up the scale, API Plan 53 introduces a pressurised barrier system using either gas or liquid to protect the inner seal. It improves reliability by maintaining a higher pressure in the barrier system than the process side, which reduces leakage and thermal stress. Although more robust than Plans 52, it still may not be optimal for applications above 180°C or where consistent circulation is needed to manage heat effectively.

API Plan 54: The Optimal Choice for High-Temperature Applications

When temperature demands become extreme, API Plan 54 offers the most comprehensive solution. It is a custom-engineered forced circulation system that delivers continuous cooling and lubrication using a pressurised external fluid system. This design ensures maximum control over heat management, even in the harshest operating environments.

At Reliability Engineering Industries, we recommend Plan 54 System: STAN100-FCS for high-temperature processes up to 200°C. This system stands out for its advanced engineering and application-focused design.

‍

Why Choose the STAN100-FCS?

The STAN100-FCS is a 100-litre oil forced circulation system engineered for reliability under pressure. Manufactured from 316 stainless steel, it is built to withstand high thermal loads while resisting corrosion. The unit includes a positive displacement pump that circulates oil at up to 4 L/min to maintain consistent cooling at the seal interface.

Designed for floor or skid mounting, the system incorporates a plate heat exchanger to dissipate heat efficiently, while its integrated pressure and temperature gauges provide precise operational monitoring. Optional features like ATEX certification and integral cooling coils further enhance its flexibility in demanding industrial settings.
