Glass-to-Titanium Sealing: The Ideal Choice for Hermetic Solutions

Sunkye specializes in customizing high-performance Glass-to-Metal Sealing Connectors that are perfect for use in harsh environments.

Hermetically tight connectors are designed for use in harsh environments such as sensors in well pipelines, oil valves, etc. This small connector was chosen because of its ability to protect equipment and complete signal transmission efficiently.

Under suitable conditions, glass will be bonded well to a wide variety of metals and alloys which has led to the development of many useful technologies. One of them is the Glass-to-metal seal technique. Glass-to-metal seals become a popular method of hermetic sealing, which is an important part of the design of Connector today. The Glass-to-metal seal technology is a fusion bonding technique; glass is heated to a molten state and bonds to the metal. Bonding occurs through wetting and chemical reactions between the metal and the glass. In addition to providing a seal, the glass acts as an insulator between one pin to another and housing.

Compared with traditional sealing metal materials such as Kovar, Alloy 52, etc. Titanium and Titanium Alloy materials have similar strength to high-quality steel, but their density, is 4 .5g/cm3, between aluminum (2 .7g/cm3) and iron (7 .8g/cm3). Titanium and Titanium Alloy materials and Kovar Alloy with glass sealed can high output current and electrical signal propagation efficiency, at the same time, it also has the advantages of low density and high specific strength.

Oil pipeline equipment usually works in a very high-pressure environment, connectors must perform their magic at extremely high-pressure differentials, often as high as 20,000 psi (137Mpa), to prevent petroleum and high pressure in one area from impacting normal environmental conditions and pressures in another. And the excellent corrosion-resisting ability of Titanium makes the connectors keep working in a harsh environment that is soaked in crude oil.

Sunkye has years of experience in providing glass-to-metal sealing solutions for the oil and gas industry. Our hermetically sealed connectors are available in various styles and are manufactured using high-density glass seal technology. With our expertise, you can rest assured that your equipment will stay protected and perform efficiently in even the harshest of environments.
