【Abstract】 Vertical radial pipe extrusion process is the production of small diameter concrete and reinforced concrete pipes of the latest technology methods. The typical vertical radial extrusion equipment structure and forming process principles are analyzed. And the common defects and the main causes of concrete pipes produced using current domestic vertical radial extrusion molding equipment are introduced. In addition, the key issues of vertical radial pipe extrusion ma chine and their solutions are put forward. Finally, the development trend of the vertical radial pipe extrusion is prospected.更多还原
