Mokhoa oa Tlhahiso ea Sehlahisoa
Litlhaloso tsena li bontša mefuta e fapaneng ea mahlakore a IPE ho latela boholo le thepa ea 'ona:
- Libalaka tsa HEA (IPN): Tsena ke libalaka tsa IPE tse nang le bophara ba flange bo boholo le botenya ba flange, e leng se etsang hore li lokele ho sebelisoa lits'ebetsong tse boima tsa meaho.
- Mahlaseli a HEB (IPB): Tsena ke mahlasedi a IPE a nang le bophara bo mahareng ba flange le botenya ba flange, a sebediswang haholo kahong bakeng sa merero e fapaneng ya meaho.
- Libalaka tsa HEM: Tsena ke libalaka tsa IPE tse nang le flange e tebileng le e tšesaane haholo, e fanang ka matla a eketsehileng le bokhoni ba ho jara mojaro.
Mabala ana a etselitsoe ho fana ka bokgoni bo itseng ba sebopeho, mme kgetho ya mofuta oo o tla o sebedisa e itshetlehile hodima ditlhoko tsa projeke e itseng ya kaho.
