HG/T20593 and GB/T9113 – all other sizes are available; however, the total height is not specified. Is it not necessary to provide the total height when placing an order?

According to the standards, indicate the flange type, diameter and its series, sealing surface, and standard number

Are you referring to the flange of LWN? Now HG/T20592 specifies the total height; if it is insufficient or too long, the corresponding symbol value can be indicated in the remarks

HG/T20592 specifies the required height for the flanges of LWN

The last edit to this post was made by xlxuiin on 2017-6-14 at 11:02. HG/T20593 does not specify the total height directly, as this value is determined by the flange structure; one can refer to the data table for values of DN, N, R, S0, S1, and the taper rate.
