Nantong Yutung Industrial Co., Ltd.  

Product Name: Continuous Cold Rolled and Sectional Screw Flights for Screw Conveyor Model NO.: Continuous Cold Rolled, Sectional Trademark: Yutung Transport Package: Pallet Specification: Continuous Cold Rolled, Sectional Origin: China Product Description Screw FlightsThe largest and professional screw flight manufacturerwith spiral manufacturing process.Backed with three manufacturing technology to produce the different types includingContinuous Cold Roller Screw Flight,Sectional Screw FlightandContinuous Equal Thickness Screw Flightwhich almost meet all the market demand on the types and sizes.Equipped with 23 screw flight forming machines, we have an annual production capacity up to 7000 tons.WIDE ASectional / Segmented Auger FlightsFEATURESA proprietary process coming into its own when material type, material thickness, big diameters, hard controlled special gauge are considerations and cannot be accomplished by conventional continuous rolled forming processA single pitch construction with consistent cross sectional thickness between inner and outer edges. Every screw flight section is formed accurately up to the customer's size.A wide range of sizes up to 2000 mm in diameter, 40 mm in thickness, and 1500 mm in pitch are availableRibbon, Tapered and Variable Pitch Flights are available on application. Flights can also be hard faced or coated with wear protection materialsHigh precision, with no minimumorder quantity requirement and customized size can be met.MATERIALSCarbon Steel, Low Alloy Steel, WearResistant Steel, Stainless Steel, etc.SPECIFICATIonSAny Screw flight with size coming in the range of the following table can be made.P--Pitch,D--Do,d--ID,T--ThicknessPitch(mm)I.D.(Min.)(mm)O.D.(Max.)(mm)Ratio of Min.O.DMin O.D.(mm)Thickness Range(mm)60~100304801.0Min O.D. = PitchCustomized x Ratio3~16100~150354800.83~18150~200505200.753~20200~250606300.73~25250~300656703~25300~350909003~30350~400909503~30400~450959503~30450~50013511503~35500~55015013003~40550~65015013503~40650~75020014003~45750~85020014003~45850~90025014503~50900~95025014503~50950~105030015003~501050~120035016000.83~501200~125040018003~501250~130045020003~50Continuous Cold Rolled Screw FlightsFEATURES·Continuous equal thickness is another proprietary process developed by our own in-house engineers with the purpose of overcoming problems like difficult forming, material wastage for small lot production.·Continuous formed pitch construction with consistent cross sectional thickness between inner and outer edges, high precision, high output and high material usage.·Manufactured in the same fashion as the screws manufactured by continuous cold rolled forming methods with the difference being consistent material thickness from inner to outer edge of the screw flight.High accuracy, low material wastageSmooth surface finish and good rigidity, easy to weld and assembleMATERIALSCarbon SteelAnyscrewflight with size coming in the range of the following table can be made.SPECIFICATIonSBand Thickness(mm)Min.
