High temperature flange operation requirements and high temperature sealing

High-temperature flanges often require flat high-temperature sealing during operation. If there is no good sealant for additional sealing in a separate pressure area during operation, it will be affected by pressure during operation, which will directly cause production. The inability or deformation, which means that there will be leakage under pressure in a single pressure area, which requires unplanned repair. The best application in the field of high-temperature flat sealing is Bocus high-temperature sealant. Its special formula makes it inert in standard applications of steam, gas turbines and high-temperature flanges, so it can withstand hot air, steam, water, and light fuel. Oils and lubricants are resistant to crude oil and natural gas.

High-temperature flanges are very suitable for working conditions that require high temperature and pressure on a smooth and flat sealing surface during operation. When operating, use a plaster knife or a rubber spatula to spread on the dry surface. Since the sealing product will not solidify, but its consistency will change slightly to maintain flexibility and elasticity, so there is no time requirement in use, and it can be put into operation immediately after construction, without waiting. If you need to repair the high temperature sealing surface damaged by scratches, you should use it with the Bocus high temperature F series repair products.

The rough shape and size of the high temperature flange are accurate, and the processing volume is small and the cost is low during operation. The internal structure of the whole product is poorly streamlined. Forged flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings are streamlined Good, denser organization, better mechanical properties than cast flanges.

In the process of making high-temperature flanges, if the forging process is improper, large or uneven grains, hardening cracks, and the forging cost will be higher than that of cast flanges. During operation, its forgings can withstand higher shear and tensile forces than castings.

The advantage of using high-temperature flanges is that they can produce a more complex shape, and the cost of the entire product is relatively low. The advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the casting. From the production process Process difference is the difference between cast flanges and forged flanges. For example, centrifugal flanges are a type of cast flanges.
