Test & Burst Pressure Calculator

Enter a working-pressure class and read the API 16C proof-test pressure (1.5×) and Welong’s published minimum burst (2.25×). These are the margins most catalogues leave off the page.

Test ratio (1.5× working pressure) follows the standard hydrostatic proof for API 16C pressure-containing equipment. The 2.25× minimum burst is Welong’s published manufacturing figure. Values are indicative; a qualified data sheet is issued per configuration.
