Valve repair commonly used materials and temperature relationships
Valve repair process, spool or valve seat and valve parts often are mechanical injury to repair these valves generally use the same material surfacing or welding, and then processed to restore its , so to fully understand the valve inner parts material and the use of temperature changes is extremely critical, the following is often encountered in the material in the valve repair procedures and use of the temperature dependence of valve repair peer help.
