Umnikelo omtsha--Perforated steel belt polyethylene composite pipe

Umbhaco wemeshi wepolyethylene oluchaswayo olubhedwe nguqembu lwenqanawe yemeshi elincane elichaswayo, kunye nombhaco ondlulayo oluchaswayo.

Ngokusho shesha kweziphumo zokugcina, umnotho wokugcwaliswa kwedwelo kukhishwa ngakwiphi. Ukukhetha amakhulu amahluke nezilithi zokuthathela ezintshangeni kufuneka zivumele izindlela ezidingekayo.

Iphayipeyi lesteel ibheke elibambeleyo elishintswini lapho lichasene nge: ususi lwamanzini, igas ethile, umoya omncane, umnandi wechemikali kunye nokusetyenziswa okanye.
