Custom Sight Glass & Wiper for Offshore Oil Platform

At Papailias Incorporated, we manufactured a 24" diameter sight glass with a custom wiper mechanism for a critical piece of equipment on an offshore oil platform. This highly specialized and technically challenging sight glass fits the criteria for pressure - temperature ratings, materials, dimensions, tolerances, and testing of ANSI B16.5. We produced this sight glass for BP, one of the world's leading international oil and gas companies.

In the wake of the Deepwater Horizon spill in the Gulf of Mexico, BP's oil and gas exploration activities have come under deep scrutiny. Based on the compelling information we supplied as part of our bid, BP was confident in our ability to manufacture a fail-safe product that would perform flawlessly and pass close inspection by regulatory authorities.

This sight glass incorporated special features for tolerating high pressure and other demanding technical specifications. Our upfront work included a complete finite element analysis. By simulating the response of the structure and materials to all environmental factors, we were able to refine and optimize the overall design concept. Built from ASTM 182 carbon steel, high strength tempered glass, and compatible elastomers, the sight glass featured a custom forged flange for superior strength and reliability. It also incorporated a high-reliability mechanism to wipe away residue on the inside surface of the lens.

Over the course of the entire manufacturing cycle, there were frequent quality audits and client inspections of the workpiece. QA involved dimensional inspection as well as analysis and documentation of physical and chemical material properties. We used a surface comparator to verify the flange finish was compatible with the gasket and hydrostatic testing to ensure a leak-proof seal.
