Custom Solutions for Manhole Sight Glasses: ACI Industriearmaturen Demonstrates Expertise

ACI Industriearmaturen GmbH has once again proven that technical expertise and innovative approaches can lead to outstanding results even in demanding projects. The focus was on the custom manufacturing of two tailor-made manhole sight glasses that were retrofitted for a tank from the 1970s.

Challenges of the Project

This project posed specific requirements for our team, which became even more complex due to the specific framework conditions:

Age of the tank

The technical documentation of the tank was outdated, incomplete, or illegible. This required a high level of technical expertise and creativity to implement the requirements accurately.

Regulatory requirements

The new manhole sight glasses had to comply not only with the applicable European standards but also with the pressure equipment directive (PED) 2014/68/EU.

Application requirements

In addition to adapting to the existing structures of the tank, the sight glasses had to be designed for high working temperatures and consider additional safety measures.

Customized Technical Solution

Our experienced team of engineers and technicians developed an innovative solution that optimally met the individual requirements of the customer. The following features characterize the customized manhole sight glasses:

Double glazing

For maximum safety and insulation, a construction with double glazing has been chosen. This not only provides protection against mechanical stresses but also ensures a reliable seal at extreme temperatures.

Flush connection

An integrated flush connection allows for effective cleaning of the glass and prevents the accumulation of residues that could impair the view of the process.

Meta glass plates

The use of meta glass increases mechanical strength and provides additional safety against breakages and leaks. This special glass is often used in safety-critical applications and is a proven standard in our product portfolio.

Special Adjustments

Thanks to our flexibility, we were able to precisely tailor the design to the requirements of the existing tank to ensure seamless integration.

The ACI Philosophy: Expertise Meets Flexibility

This project is a prime example of how ACI Industriearmaturen GmbH works: We rely on a combination of extensive expertise, high-quality materials, and a customer-oriented approach. Especially with custom solutions, our strength lies in reliably and efficiently meeting even complex requirements.

Result and Benefits

With the retrofitting of the custom-made manhole sight glasses, the tank is now not only state-of-the-art but also complies with all applicable safety and regulatory requirements. In addition, the solution provides the customer with reliable and robust process observation, which is essential for long-term operation.
