Abstract
The temperature sockets on the pressure parts of thermal power units frequently fail. The main influencing factors of temperature tube seat failure were summarized, the concept of comprehensive optimization was proposed, and the three most important influencing factors affecting the security of temperature sockets were studied. Relevant suggestions were given for the technical supervision of the temperature manifold of the thermal power unit, which provided theoretical guidance for the design and manufacture of the temperature sockets of the new unit of the thermal power plant and the maintenance and transformation of the temperature sockets of the in-service unit.
