you list this flange as 1000 psi max yet your dimensional drawing has a chart with all the code 61 flanges shows this as 3000 psi. code61 is supposed to be 3000psi and code 62 is 6000 psi. you also show the code 62 flange as 1000 psi. why is there such a low rating on these? are they somehow extra thin or something else?
A: When used to secure and seal the flange of flanged fittings, Code 61 is rated for 3,000 psi. When used as a base to convert to a machined thread of 1.5" NPT female, one must use the lowest rated portion of the conversion. 1.5" NPT female is only rated for 1000 psi working pressure. This limits the entire assembly to the 1,000 psi shown.
