Webcast: How to Select and Maintain Sight Glasses for Chemical and Pharmaceutical Applications

Improperly specified, installed or maintained sight glasses can represent the weakest link in a processing system.  The wrong glass or materials used will limit observation, require extra maintenance and replacements, and even fail under pressure with catastrophic results – since glass can fracture at 5 miles/second!

Before you choose your next sight glass, there are a variety of key specifications and glass material questions to answer, based on application temperature, how any chemicals used react to the glass, and the level of pressure involved. ​And, you’ll want to understand the differences between true borosilicate glass – its performance and certifications – compared to others that may be suggested as equivalent alternatives.

Watch this tutorial webcast from the process engineers at LJ Star to see how others are specifying and maintaining sight glass installations in their facilities.

Webcast: The Top Three Steps to Ensuring Sight Glass Safety

Keeping an Eye on Sight Glass Safety

If improperly specified, installed or maintained, sight glasses can be the weakest link in a processing system because they can limit observation capabilities, require frequent maintenance or replacement, or make it difficult to illuminate the vessel in which they’re installed.

 

Additionally, sight glasses can fail, endangering workers and causing extensive destruction and system downtime. When glass fails under pressure, it is sudden and catastrophic. Glass can fracture at 5 miles per second which can cause irreputable damage to both your workers and your facility.

 

In systems made primarily of metal, such as pressure vessels or process piping runs, the weak spots are generally sealing joints and glass.  Typically, failure of an industrial sight glass on a piece of equipment, or within a piping system, will halt the entire manufacturing process and force downtime until the equipment can be repaired or replaced.

 

 In this webcast, How To Ensure Sight Glass Safety, you’ll learn how to choose the right sight glass for the application and applicable standards, how to install the sight glass correctly and how to routinely and carefully maintain sight glasses.

ASME Process Instrumentation Committee Makes Progress at Recent BPE Meeting

ASME LogoMichael Bosley, one of L.J. Star’s Product Support Specialists, took part in ASME Bioprocessing Equipment (BPE) Committee Meetings, held May 7-10, 2018, in San Diego, California. As a leading supplier to the biotechnology industry, we take our responsibility to participate in advancing the industry very seriously. By participating in the work of these committees, we hope to stay on the leading edge of evolving technologies; at the same time, we want to share updates on the topics these committees are weighing with you, so you can stay up to date on industry trends.

Mike participates in the Subcommittee on Process Instrumentation, part of the Bioprocessing Equipment Standards Committee and the Board on Pressure Technology Codes and Standards. Process instrumentation includes sensors, transmitters, analyzers, controllers, recorders, transducers, control elements, and supporting components such as light sources and sight glasses.

The Task Group on Optical Devices was formed to revise the language in the Optical (sight glass) section of the BPE Specification and move that content from System Design (SD) to Process Instrumentation (PI). The task group will be responsible for content related to sight glasses, fused glass, and lighting.

The four-year Task Group on Turbine Flow Meters is charged with adding new content to the BPE Specification on the use of Turbine Flow Meters in product contact lines. The section for Turbine Flow Meters has been written from scratch, balloted numerous times, revised and re-submitted, and is now undergoing final balloting. Non-mandatory content is also being developed while balloting continues.

The Subcommittee on Process Instrumentation has begun development of a template for use as an unofficial guide for developing new content. This template has been submitted to the Main committee and has been accepted for use. Process Instrumentation Subcommittee members have voted and approved the use of the template, and a formal ballot to the Main Subcommittee will follow.

How BioGas Sightglass Keeps an Eye on Green Energy

     Say green energy, and the first words that spring to most minds are likely either solar power or wind power. But there’s another important player in the alternative energy marketplace─biogas generation.

     Biogas is produced when organic matter breaks down in the absence of oxygen. It’s produced by anaerobic digestion by bacteria or fermentation of biodegradable materials such as manure, sewage, municipal waste, or plant material. Like solar and wind power, it’s a renewable energy source. It can be used as a fuel in a variety of applications; when cleaned and compressed, it can power motor vehicles.

     In the United States, anaerobic digesters for farm animal waste are typically large, heated stainless steel tanks fitted with tightly sealed sight glass windows to allow operators to monitor mixing and digestion to ensure efficient operation. These biogas sight glasses are often equipped with explosion-proof LED lighting and cameras, as well as spray nozzles and wipers to keep the window clean despite the often-messy process material. To learn more about what goes into matching the sight glass to the application, watch our new video: “Biogas Sight Glass Use and Selection.”
