1. DN ka lebitso:
Flangebophara ba lebitso bo bolela bophara ba setshelo kapa phala e nang le flange. Bophara ba setshelo ka lebitso bo bolela bophara bo ka hare ba setshelo (ntle le setshelo se nang le tube e le cylinder), bophara ba lebitso la phala bo bua ka bophara ba eona ka lebitso, e leng boleng bo pakeng tsa bophara bo ka hare le bophara bo ka ntle ba phala, tseo boholo ba tsona li leng haufi le bophara bo ka hare ba phala. Bophara bo ka ntle ba phala ea tšepe e nang le bophara bo tšoanang ba lebitso bo tšoana, 'me bophara bo ka hare bo boetse bo fapane hobane botenya bo ntse bo fetoha. 14 Sheba tafole ea 1.

2. Khatello ea lebitso PN:
Khatello ea lebitso ke boemo ba khatello e abetsoeng ka morero oa ho theha maemo. 14 Sheba tafole ea 2.
3. Khatello e phahameng e lumelletsoeng ea ho sebetsa:
Khatello ea lebitso ka har'a khatello ea sekepe sa flange standard e khethoa tlasa boemo bathepa ea flange16Mn (kapa 16MnR) le mocheso oa moralo 200oC. Ha thethepa ea flangele phetoho ea mocheso, khatello e phahameng e lumelletsoeng ea ho sebetsa ea flange e tla eketseha kapa e fokotsehe. Ka mohlala, khatello e phahameng e lumelletsoeng ea ho sebetsa ea flange e telele ea molala butt welding e bontšoa ho Lethathamo la 14-3.
