What is BS EN 13958 - Cold drawn, round, coiled tube about?
BS EN 13958 specifies the tolerances on dimensions and form of round aluminium and aluminium alloys porthole extruded and cold drawn tubes with an outside diameter (OD) of over 2 mm up to and including 50 mm supplied in coil form or straight lengths cut from coiled material.
BS EN 13958 mainly applies to round cold drawn tubes for general engineering applications manufactured in 1xxx series of aluminium and 3xxx series of alloys. The use of BS EN 13958 for non-standardised 1xxx aluminium and 3xxx alloys or alloys from other series, e.g. 5xxx or 6xxx, is subject to agreement between supplier and purchaser.
BS EN 13958 only applies to:
- Round tube extruded by the porthole/bridge method in coil form and then cold drawn to the final dimensions required
- Tube as above but delivered in straight lengths cut from coiled material
BS EN 13958 does not apply to:
- Seamless extruded (die/mandrel method) and drawn tubes (EN 754-7)
- Tubes extruded in straight lengths (i.e. Not coiled) and drawn (EN 754-8)
Who is BS EN 13958 - Cold drawn, round, coiled tube for?
BS EN 13958 on the cold drawn, round, coiled tube is relevant to:
- Manufacturer of the cold drawn, round, coiled tube
Why should you use BS EN 13958 - Cold drawn, round, coiled tube?
Porthole extruded tubes are commonly referred to as “structural” or porthole tubing. The aluminum association describes these tubes as: “a tube produced by extrusion of a solid billet through a porthole die.
BS EN 13958 provides guidance on production and manufacturing processes, quality control, chemical composition limits, mechanical properties, surface quality, coil characteristics, tolerances on dimensions.
With the guidance of BS EN 13958, you can efficiently manufacture high-quality aluminium and aluminium alloy cold drawn, round, coiled tubes. With BS EN 13958 you can be ensured that the products consistently meet and exceed quality assurance targets. BS EN 13958 exemplifies the required chemical, mechanical properties that help you achieve precision in terms of product functionality and specification. BS EN 13958 provides you with comprehensive information useful throughout the process of production.
