Phi 31 Copper washer for ship

The copper gasket can be processed into various semi-finished products and finished products by cold and thermoplastic processing. The precise turning of the CNC lathe ensures that the sealing surface is flat and warped, and the high-precision grinding ensures that the metal surface closely fits the flange sealing surface. The bolted flange connection structure is usually adopted. Therefore, the bolts must be pre-tightened enough to meet the requirements of preliminary sealing during assembly. Accurately controlling the pre-tensioning level is a very difficult problem. Secondly, the gasket is more affected by this structure. Many factors affect the sealing element.
