Mabitso ana a bolela mefuta e fapaneng ea maballo a IPE ho ipapisitsoe le boholo le thepa ea ona:
- libalaka tsa HEA (IPN).: Tsena ke maballo a IPE a nang le bophara bo pharaletseng haholo le botenya ba flange, e leng se etsang hore e tšoanelehe ho sebelisoa lits'ebetsong tse boima tsa meralo.
- Mabala a HEB (IPB): Ana ke maballo a IPE a bophara ba flange e mahareng le botenya ba flange, a atisang ho sebelisoa ha ho etsoa merero e fapaneng ea meralo.
- Lifate tsa HEM: Tsena ke maballo a IPE a nang le flange e tebileng haholo le e moqotetsane, e fanang ka matla a eketsehileng le bokhoni ba ho jara mojaro.
