Papailias manufactures the highest quality sanitary and industrial sight glasses on the market today. Designed to view conditions within process vessels, sanitary sight glasses suit applications in the food, dairy, and pharmaceutical industries, while industrial sight glasses are ruggedly built to handle harsher environments.
We offer a full range of process observation equipment to meet the needs of various types of process vessels and reactors. Our products can be constructed from a variety of ASME Section VIII acceptable metals including carbon steel and 304, 304L, 316 and 316L stainless steel to meet the needs of any system. Virtually any machinable alloy can be specified to meet user requirements and we also offer a full complement of optional accessories such as lighting, wipers, and washers.
Industrial sight glasses are available as circular or rectangular versions with glass that can withstand high temperatures and pressures. We offer numerous viewing dimensions and can manufacture custom sizes upon request.
Sanitary sight glasses are a circular system made with a leak-tight, tool-less assembly/disassembly standard sanitary clamping system to prevent any type of contamination from entering into the process stream and making for easy cleaning or sampling. They can be specified without the welding ferrule for mounting to the vessel connections. Our BoroAlloy™ Clamp Glass/Metal Alloy products are approved for sanitary applications, including CIP and SIP, and feature a single piece construction and borosilicate glass.
With more than 30 years of experience in designing and manufacturing sight glasses for sanitary and industrial applications, Papailias can be counted on for reliable and fail-proof products.
