Cold formed sectional screw flight, strictly control the inner and outer diameter and pitch, then weld it into the continuous screw shaft, form a smooth spiral propulsion for delivery. It can greatly reduce the use of blade wear, energy consumption, and improve the efficiency of material transport per unit time. Our products have been widely used in mining, chemical industry, food production, food processing, environmental protection and building foundation and other industries.
Production process: cold forming technology
Product advantages: Formed by cold forming technology, our sectional screw flight with equal thickness does not affect the physical properties of the product material. It has accurate inner, outerside diameter and pitch; We are able to form large outer diameter, large thickness, large pitch sectional screw flight.
Common materials: carbon steel, alloy steel, stainless steel, wear-resistant steel, etc.
Product specifications: customized according to request, outside diameter up to 4000mm, plate thickness up to 70mm;
Product usage: sectional screw flight can be used in spiral conveyor, mixer, pile driver, drilling machinery and other equipment etc., conducting to material transportation and clean drilling. It can greatly improve the working efficiency of equipment.
The cold forming technology for sectional screw flight is a solution for special sizes of helix, which may be larger outside diameter,or thicker plate or larger pitch etc. The continuous flight forming machine can not produce this type of helix, including in different type of material, for example stainless steel, wear resistant steel. We are able to form these helical with accurate specification. With our helix, the client can assembly the screw shaft efficiently.
The maximum specification for OD, ID and Pitch we can reach:
OD 4000mm;
ID 16mm
Pitch 3000mm
Thickness: up to 70mm.
We can form all kinds of sectional screw flight based on maximum specification no matter tapered OD or ID, various pitch, notches etc.
All the sizes of helix can be custom ordered to match the client requirement. We supply to all different type of screw conveyors industries, environmental protection machineries, screw pile foundation etc.
