一、 What is the product?
Sanitary grade quick installation glass tube sight glass (also known as quick installation sight cup, sanitary grade pipeline sight glass) is an industrial accessory installed on sanitary grade pipelines to directly observe the flow and state changes of the medium inside the pipeline.
It adopts a quick release clamp interface design, matched with food grade seals, and uses stainless steel as the main material and transparent glass tube as the observation component. It combines the characteristics of convenient disassembly, sanitary sealing, and high transparency observation, and is widely used in fluid transportation and production pipelines with strict requirements for hygiene level and cleaning convenience.
二、 Core Structure and Material Analysis
The structural design of this mirror is fully centered around the four core requirements of "hygiene, safety, convenience, and durability", and the materials and processes of each component are adapted to the standard requirements of sanitary production scenarios
1，main framework
Made of 304/316L stainless steel material, among which 316L stainless steel has stronger corrosion resistance and is more suitable for special scenarios such as pharmaceuticals and high acidity and alkalinity chemicals. The surface of stainless steel is polished with a mirror finish, and the Ra value is usually ≤ 0.8 μ m, reducing dead corners of medium residue and bacterial growth, and meeting the hygiene standards of the food and pharmaceutical industries.,
2，Transparent observation section
The middle observation component is a high borosilicate tempered glass tube, and some high-end models use quartz glass tubes. High borosilicate glass has the characteristics of high transparency, high temperature resistance, high pressure resistance, and temperature difference resistance. It can clearly display the color, flow rate, bubbles, liquid level, and other states of the medium inside the pipeline. At the same time, it can withstand the high temperature environment of CIP/SIP cleaning and disinfection in sanitary production.
3，Quick installation connection interface
Both ends are equipped with sanitary grade Tri Clamp interfaces, paired with food grade silicone/EPDM sealing rings. The interface size is compatible with industry standard pipeline specifications (such as 19mm, 25mm, 38mm, 51mm, 63mm, etc.), without the need for welding or threaded connections. Only clamps are needed to quickly connect with the pipeline, making disassembly and assembly convenient.,
4，Strengthen the protective structure
Equipped with stainless steel pull rods and protective bolts, the stainless steel flanges at both ends are fixed, which can prevent displacement of the glass tube due to pressure fluctuations and provide protection in case of accidental glass breakage, avoiding debris splashing and improving safety during use.
三、 Main application industries and scenarios
The characteristics of sanitary grade quick installation glass tube sight glasses make them widely used in multiple industries with strict requirements for hygiene levels:
1，Food and beverage industry
It is used in the transmission pipeline of fruit juice, dairy products, beer, sauce and other foods to observe the flow state, filling level and foam of the media, and it is suitable for food grade cleaning process to avoid media pollution.,
2，pharmaceutical industry
Used in pharmaceutical pipelines such as drug delivery, reactor discharge, and purified water pipelines to monitor real-time changes in the color and concentration of drug solutions, meeting the GMP hygiene standards of the pharmaceutical industry and ensuring the safety of drug production.
3，Fine chemical industry
Suitable for chemical raw material transportation and reaction process monitoring pipelines with high hygiene requirements, observing the reaction state and mixing situation of the medium, and withstanding the corrosion of some acidic and alkaline media.,
4，water treatment industry
Applied in sanitary grade pipelines for purified water, water treatment, and sewage treatment, monitoring water flow status and water quality changes, and adapting to the online cleaning and disinfection process of water treatment systems.
5，Other scenes
It can also be used in daily chemical and cosmetic production pipelines, as well as small hygiene grade production lines such as beer brewing and dairy processing, providing visual monitoring support for the production process.
