Additionally, the behavior of FRP-reinforced concrete under service loads differs from that of traditional reinforced concrete. Due to the linear stress-strain relationship of FRP materials, structures tend to have a more brittle failure mode compared to the ductile behavior of steel-reinforced concrete. As such, design codes need to incorporate specific considerations for failure mechanisms, ensuring that structures remain safe under unexpected loading conditions.

- The '794' could refer to the heat range of the plug, indicating its ability to dissipate heat effectively, ensuring a stable firing under various load conditions. The ' 000' might symbolize the plug's double-digit rating, suggesting its enhanced durability and resistance to wear, allowing it to last for thousands of miles without needing a replacement.
Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.




Requirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.
