Nowadays, the emergence of new materials of construction of lightweight, safety, health, energy saving, high efficiency, beautiful, and cheap, healthy, and began to meet environmental protection requirements. HDPE hollow wall winding pipe and its supporting products, belong to the Chinese government vigorously promote, application of chemical building materials with light weight, long service life, resistant to chemical corrosion, both inside and outside is smooth, the overall price moderate, transport, installation is convenient wait for a characteristic, can be widely used in highway, municipal construction, residential area, playground, square, mining, agriculture, culverts, Bridges, and other fields of drainage sewage pipe.

SBG large caliber hollow wall winding pipe production line is my factory in combination with the international advanced equipment developed by the new pipe equipment, has the production speed, molding process stability. Production line adopts the most advanced modular design, operation and maintenance is very convenient.

　　SBG winding pipe production line of large diameter hollow wall of pipe with high density polyethylene as the main raw material, by the first extruder extrusion tube by cooling presses shapes round square tube, and then into the winding machine, at the same time the second extruder extrusion melt glue glue the square tube in a spiral form, its internal and external wall level off is smooth, specifications from 200-3000 - mm,

　　According to the different conditions of use ring stiffness is divided into four grades, and maximum 16 kn/m2, this kind of tubing corrosion resistance, light quality, easy installation, high flux flow, and the advantages of long service life (50 years), alternative energy materials (cement, iron, ceramics, etc.) production of pipe material, widely used in highway, municipal construction, residential area, playground, square, mining, agriculture, culverts, Bridges, and other fields of drainage sewage pipe.
