BS EN 10305-3:2016

What is BS EN 10305-3 - Welded cold-sized tubes about?  

BS EN 10305 is a European standard on steel tubes for precision applications that discusses the required best procedures and specifications required for manufacturing high-quality welded cold-sized tubes. BS EN 10305-3 is the third part of a series of documents on steel tubes for precision applications. BS EN 10305-3 specifies the technical delivery conditions for welded cold-sized steel tubes of the circular cross-section for precision applications with specified outside diameter D ≤ 193,7 mm. 

BS EN 10305-3 may also be applied to other types (excluding square and rectangular) of the cross-section. 

Tubes according to this document are characterized by having precisely defined tolerances on dimensions and specified maximum surface roughness. Typical fields of application are in the vehicle, furniture, and general engineering industries. 

Who is BS EN 10305-3 - Welded cold-sized tubes for?  

BS EN 10305-3 on steel tubes for precision applications is relevant to: 

• Manufacturer of welded cold sized tubes  

Why should you use BS EN 10305-3 - Welded cold-sized tubes? 

A welded tube is produced through roll forming strips or sheets of stainless steel into a tube shape and then welding the seam longitudinally. 

BS EN 10305-3 provides guidance on classification and designation, steelmaking process, tube manufacture, and delivery conditions, chemical composition, mechanical properties, appearance, internal soundness, dimensions and tolerances, inspection, and test methods. 

BS EN 10305-3 exemplifies the required chemical composition, mechanical properties, outside diameter, inside diameter, wall thickness, and eccentricity that help you achieve precision in terms of product functionality and specification. 

As a user of BS EN 10305-3, you can be ensured of technical delivery conditions for welded cold-sized steel tubes. With obedience and compliance to BS EN 10305-3, you can efficiently manufacture high-quality precise welded cold-sized steel tubes. With BS EN 10305-3 you can be ensured that the products consistently meet and exceed quality assurance targets. BS EN 10305-3  provides you with comprehensive information useful throughout the process of production.
