corrugated pipe machinery: The production equipment and its technology for the corrugated pipe winded with steel strip were developed in the 1990’s. They are now widely used in many fields in the developed countries, especially for water, drainage, sewerage piping in industries and agriculture in USA, Canada, Japan, Korea and the European countries.An extrusion line for the corrugated pipe winded by steel strip is newly presented by Hengchangtai, combining international advanced technology, with a diameter range of ID 800 mm—3,500 mm, which fills the gap in China and is the best choice for replacement of the imported ones Main machine adopt two-stage type pressure-reduction screw, with special mixing plasticity component, which can ensure use recycling material to produce under the condition of high toque and high temperture contronl precision. Supplied goods by two machine, form shape by helix rotation, high compound tech-art, to ensure the high quality of product. To use special plastic-steel combination technology, to ensure the pipe reliable property Main Features 1 The strip pitch can be easily adjusted by a pitch mechanism so as to achieve the best ring stiffness and the lowest unit weight. 2 The forming and bending of the strip and forming of the composite pipe is synchronically controlled by PCC control system, avoiding disadvantages of pulling off, piling up and breaking of the strip during forming, ensuring 100% of the finished product rate. 3A special composition device makes the forming of the spiral strip and inner pipe stable, with adjusting function both for inner and outer wall thickness. 4 A professional PCC (B&R, Austria) control system is adopted for high automation, reliable running and easy operation. 5Long-distance communicative function can realize tele-diagnosis and maintenance. Product features (1) Light weight, high ring stiffness, low cost, with strong market competitive power. Under the same diameter and ring stiffness, thelightest weight per meter can be obtained for the pipe over 800 mm of diameter and materials can be cut down by 20%-60% in comparison with those of hollow winded pipe, moulding ribs winded pipe and double wall corrugated pipe. (2) Easy and reliable connecting, by thermo-melt coupling (for the purposes of drainage, sewerage and ventilation) or thermo-shrinking film, or outer half-block with sealing rings. (3) Excellent low temperature resistance, being installed between -60°C 60°C. (4) High complete strength, bearing large axial tensile force and circumferential ring stress. (5) Good soil adaptability. It has a good adaptability without breaking for resisting earth settlement and movement because of high coefficient at rupture which is up to 500%. (6) Excellent flowing performance. The flow is bigger than that in cement pipe under the same diameter because of the small flow resistance. (7) Excellent wear and corrosion resistance. Its life is longer than that of the cement pipe. (8) Being green product for environmental protection, without any pollutionPurposes of the Product (1) It can be widely used in the drainage and sewerage piping of municipal construction. (2) Irrigation engineering for farmland, irrigation network, water supply and drainage flooded fields. (3) Fluid conveying in chemical and mineral Industries. (4) Piping in factories, sewerage treatment plants and other public places.HDPE large diameter steel (Main Technical Parameters TYPE PIPE OD(mm) MOULD SIZE(mm) EXTRUDER OUTPUT(kg/h) (m/min) INSTALLED POWER(kw) LINE LENGTHM SGB400 225-400 225,300400 SJ75/33 SJ75/33 600 5.0 480 SGB600 225-600 400,500600 SJ90/33 SJ75/33 800 5.0 580 SGB800 225-800 500,600,800 SJ120/33 SJ90/33 1000 3.0 750
