Ibisobanuro bigufi:

Iki gice cyibipimo ngenderwaho byu Burayi byerekana uburyo bwogutanga tekinike yubukonje bwubatswe bwubatswe bwubatswe, ibice byubusa byuruziga, kare cyangwa urukiramende kandi bikoreshwa mubice byubatswe byubatswe bikonje bitarinze kuvurwa ubushyuhe.

Cangzhou Spiral Steel Pipes Group Co, Ltd itanga igice cyubusa cyumuzingi uzenguruka imiyoboro yicyuma.
