IFlange enemisonto

I-Screwed okanye i-Threaded flanges isetyenziswe kwimigca yombhobho apho i-welding ayinakuqhutywa. Iflange enemisonto okanye ifakelo ayilungelanga inkqubo yombhobho enobungqingqwa bodonga olubhityileyo, kuba intambo yokusika kumbhobho ayinakwenzeka. Ngoko ke, ukutyeba kodonga kufuneka kukhethwe.ASME B31.3 Umbhobho weSikhokelo uthi:Apho umbhobho wentsimbi uthungelwa kwaye usetyenziselwa inkonzo yomphunga ngaphezu kwe-250 psi okanye kwinkonzo yamanzi engaphezu kwe-100 psi ngamaqondo obushushu angaphezulu kwama-220 °F alinganayo kwaye ishedyuli iya kuba ne-seam ye-ASME elingana ne-8 F, ishedyuli iya kuba ne-seam ye-ASME ubuncinane B36.10.I-Socket welding kunye ne-threaded flanges ayikhuthazwa kwinkonzo engaphezu kwe-250 ° C nangaphantsi kwe -45 C.
