1. What Is a Valve Welding Electrode? A valve welding electrode refers to a category of welding consumables specifically used for hardfacing, repair welding, and overlay welding of valve components, including the valve body, sealing surfaces (such as valve seats and valve discs), as well as welding joints between valves and pipelines. It is not a single product, but rather a general ...

In seawater piping systems, globe valves can be used to control and isolate fluid flow, provided that the materials and corrosion protection design are suitable for seawater service conditions. Seawater contains a high concentration of chloride ions and dissolved oxygen. If the valve material is not properly selected, corrosion can occur rapidly. Therefore, when globe valves are used in sea...

Valve pressure rating is one of the primary parameters used to determine whether a valve can safely operate in a specific piping system. In industrial applications, pressure class does not simply represent the maximum working pressure of a valve. The actual pressure capability depends on the pressure-temperature rating defined by standards such as ASME B16.34, as well as valve materials, design co...
