Kutshanje, abathengi baya kuza kumzi-mveliso wethu ukutyelela imveliso kunye nokulungiswa kwempahla. Imibhobho yentsimbi engenamthungo ethengwe ngumthengi ngeli xesha inaloI-ASTM A106imigangatho kunyeI-ASTM A53imigangatho, kunye neenkcukacha 114.3 * 6.02.
Eyona njongo yotyelelo lomthengi kukwenza uhlolo kwindawo yomzi-mveliso. Abaphathi bethu kunye nabathengisi baya kukhapha umthengi kuyo yonke inkqubo ukubabonelela ngentshayelelo ebanzi kunye nenkonzo.
