Introduction and selection of electrical penetration joint

Cryogenic technology is mainly used in energy, transportation, medical health, electronic technology, aerospace, scientific experiments and other fields of cryogenic environment. In the field of energy, replacing coal with oil and gas is an important choice to comply with environmental regulations. The development and utilization of natural gas involves its liquefaction and transportation, so the derivative such as LNG receiving stations, LNG liquefaction plants, LNG carriers, floating LNG liquefaction storage devices, etc., involve the liquefaction and transportation of energy gases, and these processes require the use of low-temperature submersible pumps and low-temperature electrical penetration joints for the power supply and measurement and control of the submersible pumps. LNG, alkanes, olefins and other low temperature media have the characteristics of low temperature, flammable, explosive and easy to vaporize.

Therefore, the working conditions of the pump transporting this medium are poor, the requirements of materials, sealing and other aspects are very demanding, and the equipment requirements have the requirements of sealing safety and reliability. Due to small market consumption, difficult design, manufacturing and testing difficulties, it is still dependent on imports. Using its own technical advantages, Dongyuan has devoted itself to the development of low-temperature electrical penetration joints, obtained a number of zhuanli, and passed the national explosion-proof product certification. At present, the products cover SBD-JT series and SBD-XT series 2 major categories, to meet the different application projects of LNG. (ELECTRICAL PENETRATION,ELECTRICAL TERMINAL HEADER)
