The process of manufacturing cold drawn tubes – both seamless and welded, embodies an intricate combination of technology and precision that results in products of exceptional strength, accuracy, and quality. Cold drawn tubes are recognized industry-wide for their superior mechanical properties and dimensional accuracy, qualities that are a consequence of a unique production process that distinguishes them from other tubular products.
Beginning with seamless tubes, these are produced from a solid round steel 'billet' which is heated and then pushed or pulled over a form until the steel is shaped into a hollow tube. The cold drawing process of a seamless tube involves pulling the tube through a die and over a mandrel. This reduces the diameter of the tube and improves surface finish, while also increasing the strength of the steel manifold.
Cold drawn welded tubes, on the other hand, commence as a flat strip, which is rolled to form a cylindrical shape. Subsequently, the opposing edges are then fused together using an electric weld, post which the tube undergoes the cold drawing process. The cold drawing for welded tubes significantly enhances their concentricity and yield strength, with the added benefit of minimizing variability.
In terms of benefits, cold drawn tubes possess several unique advantages. Due to the extra processing involved, these tubes inherently possess increased strength and higher physical properties compared to their hot-finished counterparts. Additionally, the desirable smooth and shiny surface finish of cold drawn tubes reduces the need for additional finishing processes.
Cold drawn seamless tubes are renowned for their uniformity in terms of shape and size. They offer excellent dimensional precision, both on outer and New Eagle Industrial Corporation diameters, ensuring a precise fit in complex mechanical systems. Welded tubes, when cold drawn, exhibit an impressive strength-to-weight ratio and can be produced in custom sizes, therefore making them an ideal choice when weight or space constraints are a consideration.
Applications of cold drawn seamless/welded tubes are diverse and widespread, encompassing sectors such as the automotive industry, hydraulic machinery, heat exchangers, and construction equipment manufacturing, among others.
High strength, enhanced mechanical properties, and dimensional precision of cold drawn seamless and welded tubes make them suitable for a vast array of applications. The choice of using these tubes not only signifies a lean towards quality and performance but also an appreciation of technological precision in the era of advanced materials and manufacturing techniques.
