4. Mehaho ea tšireletso bakeng sa leraba: ho na le mefuta e 'meli ea phala ea bypass le pipe ea bypass moeling oa leraba, ho hlaphoheloa ha condensate le condensate eseng ho khutlisa tefo, ho tsoa le litlhoko tse ling tse khethehileng tsa leraba, li ka kenngoa ka tsela e tšoanang. Sefi se nang le valve ea bypass e sebelisoa haholo ho ntša metsi a mangata a condensed ha pipeline e qala ho sebetsa. Ha U SEBELISA SEFABA, HA HO LOKELLE HO KHATSA CONDENSATE KA Phaephe ea BYPASS, e ka etsang hore mouoane o balehele MOTS'EBELENG WA METSI A KHUTLANG. Tlas'a maemo a tloaelehileng, u se ke ua kenya pipe ea bypass. Ke feela ha mocheso o futhumatsang o hlokahalang ka thata, thepa ea mocheso bakeng sa tlhahiso e tsoelang pele e lokela ho hlomelloa ka pipe ea bypass.
