SPECIALTY & CUSTOM SIGHT GLASS WINDOWS

Science, engineering and applied research; terms that refer to a scope of work so vast and complex that the meanings and implications are virtually limitless. Professionals working in these fields are often engaged in searches for products and services that will keep them on the cutting edge. The list of suppliers at their disposal can be overwhelming…except when it comes to Sight Glass Windows.

Because of the unique and challenging nature of glass, few companies have accumulated the skills and knowledge base to produce a wide range of high tech custom Sight Glass solutions. Applying a glass making technique to a particular challenge may solve one problem; but knowing how to engineer integrated solutions generates lasting value to customers.

Why Rayotek?

  • Much like our clients, Rayotek continually seeks new solutions through innovation, experimentation, applied research & ongoing R&D
  • All design, engineering & manufacturing is performed in-house in Rayotek’s U.S. facility
  • Full-time, on-staff Sight Window Engineers are available for customer consultations & co-engineering
  • Rayotek has amassed an extensive database of custom manufactured & tested Sight Glass Products

Applications
Rayotek develops custom products for working environments, including:

  • Aerospace (from high speed atmosphere to space)
  • Critical sour process operations in oil & gas (O&G) systems (API Spec)
  • Lethal service pressure vessel applications (ASME Spec)
  • Subsea O&G processing, inspection & intervention
  • Cryogenic & refrigeration systems
  • HPHT systems for scientific research & observation
  • Combustion analysis (high temperature) in laboratory environments
  • Downhole camera & video systems for drilling tools, downhole equipment & well intervention
  • High pressure flow cells for laminar flow analysis

Capabilities

  • Pressure Ranges - ultra-high vacuum to 100Kpsi (6890bar)
  • Temperature Ranges - cryogenic temperatures of ~ -150°C (-238°F) to 1850°C (3362°F)

Specifications met or exceeded include but are not limited to:

  • ASME B31.3, B16.5, DIN/EN (7080 & others), ANSI, AS9100, Sanitary 3-A, USP Type1/Class 6, BPE, PED Directive 97/23/EG


For applications that fall outside Rayotek's established database, Rayotek uses a Front End Engineering and Design (FEED) process to ensure quality and mitigate risk. The FEED Process can shorten development time, reduce costs and increase success rates by ensuring that all Rayotek departments and the customer collaborate in the design, manufacturing and testing processes.


The following steps allow Rayotek to determine if an inquiry will be fulfilled by a stock or custom solution.

  1. Customer provides project details by completing the Rayotek Customer Spec Form. Some details to consider:
    • Pressure requirements (max/min/test)
    • Housing type (flanged, threaded, etc.)
    • Temperature (max/min)
    • Clarity requirements
    • Clear aperture
    • Chemical exposure
    • Quantity
    • Project budget
  2. Rayotek reviews requirements:
    • A Rayotek Sight Window Engineer reviews the Rayotek Customer Spec Form and reaches out for further clarification.
    • A determination is made on whether a Rayotek Stock or Custom Sight Window will be the best solution. Rayotek will always recommend a stock option if possible
  3. Rayotek provides a formal quotation as quickly as possible.
