Product Description

JIS B8286 Tempered Sight Glass | High-Strength Industrial Glass Supplier

In industries such as petrochemicals, steel metallurgy, shipbuilding, and biomedicine, strict requirements are placed on the safety, reliability, and standardization compliance of sight glass equipment
Insufficient stability in high-pressure, high-temperature, and highly corrosive environments can easily lead to glass breakage and leakage, posing a threat to production safety;
Lack of international standard certification, such as JIS B8286, may result in equipment acceptance failure or export obstruction;
Customization needs are difficult to meet, and conventional products cannot adapt to special sizes, pressure levels, or complex working conditions.

Lumistar Solution:

1. Strictly follow JIS B8286 standard, with high-strength performance guarantee
The tempered mirror glass of Lumixing JIS B8286 has undergone special tempering process, with a strength more than 5 times that of ordinary glass, and can withstand a pressure level of 10K/20K (such as the ISUNTON JIS B8286-10K/20K series). It has a wide temperature resistance range and strong thermal shock resistance, effectively resisting high-pressure fluid impact and extreme environmental corrosion, reducing the risk of equipment failure from the source.

2. Multi standard adaptation and global certification
In addition to JIS B8286, it also covers international safety glass standards such as DIN7080 and BS3463 to meet different market access requirements; Our products have been exported to over 150 countries and have gained long-term trust from international customers such as Siemens and Bayer.

3. Customized services throughout the entire processOn demand design

Provide personalized solutions such as size, thickness, and edge treatment based on pipeline/container specifications, pressure ratings, and medium characteristics;
Quality controllable: from raw material screening to CNC precision machining, full traceability quality control, pressure/sealing testing before leaving the factory, to ensure that each piece of glass meets the working requirements.

4. High cost-effectiveness and long-term reliability
Refuse to sacrifice quality in low-priced competition, achieve cost optimization with advanced equipment, and provide long-term stable solutions for key components such as high-pressure vessels and pipeline sight glasses.

Applications

1.Chemical reaction equipment: Corrosion resistance and thermal shock resistance

2.high pressure steam system: Strong pressure resistance and long-term stability
