3 Considerations When Buying Special Material Valve

01 Oxidation Resistance

When buying a Special Material Valve, it’s important to consider the valve’s oxidation resistance. Oxidation resistance makes sure that the valve will maintain its integrity even when exposed to high temperatures or corrosive substances. For example, with the aggressive chemicals in the chemical plant a valve with strong oxidation resistance will provide longer service life.

02 ASME B16.34 Certified

Another key consideration is whether the valve is ASME B16.34 certified, which certifies that the valve meets stringent industry standards. This certification is crucial for large-scale projects where safety and compliance are non-negotiable. NTVAL’s Special Material Valves are ASME B16.34 certified, guaranteeing that they meet the highest standards required for industries like oil and gas or chemical processing.

03 Nondestructive Tested

It’s essential to consider whether the Special Material Valve has undergone nondestructive testing (NDT) as part of its quality assurance process. Nondestructive testing certifies that the valve is free from cracks or other imperfections that could compromise its performance. Want to know a secret? Special Material Valves tested using NDT methods guarantee their integrity and performance in the most demanding environments.
