Ka la 8 Phupu, 2023, re ile ra romela liphaephe tsa tšepe tse se nang moalo tsa ASTM A335 P92 Italy, 'me ra li tlisa ka nako. Lekhetlong lena, re entse liphutheloana tse matlafalitsoeng ka 100%, ho kenyeletsoa liphutheloana tsa PVC, liphutheloana tsa mekotla e lohiloeng, le liphutheloana tsa pampiri tse tletseng seponche, tse ka sebelisoang hape ka kakaretso. Lithapo tsa tšepe li sebelisoa ho kopanya liphaephe, 'me liphaephe tse pela tsona li tletse pampiri ea lipululana e thibelang ho thulana le pampiri ea ho tlatsa seponche, 'me qetellong li pakiloe ka mabokoseng a lehong. Ka ntle ho lebokose la lehong, re boetse re sebelisa lebanta la tšepe le matla haholo ho lokisa lebokose, e le ho sireletsa kahare le kantle ho phaephe ka kakaretso.
Ho tlisoa ha lihlahisoa ho tsoa ho bareki ba Italy ho thehile motheo o betere bakeng sa 'maraka oa rona oa Europe, 'me re labalabela tšebelisano-'moho ea rona e latelang!
