ECISS/TC 29/SC 5 - tube for the conveyance of aqueous liquids

This European Standard specifies a range of jointing methods for connecting low alloy steel tubes and steel tubes and fittings for use with aqueous liquids.
The following specific joint types are covered by this document: butt welded joints, welded spigot and socket (or sleeve joints), welding collars, flange joints, threaded joints, spigot and socket joints with seal and mechanical couplings.
This European Standard specifies requirements for the strength and integrity of the joints and the testing of the joints.
This European Standard does not specify the requirements for the tubes or the fittings.
This European Standard is suitable for joints intended for the conveyance of water for human consumption, after an appropriate coating has been applied.
This European Standard is not intended for use in heating networks where elevated temperature properties are required.
Flexible joints which permit significant angular deflection, both during and after installation and which can accept slight offset of the centre line, are not covered by this European Standard.

This European Standard specifies the technical delivery conditions for light gauge welded stainless steel tubes, primarily for water application, including water intended for human consumption, supplied in straight lengths and suitable for connection by adhesive bonding, capillary fittings, compression fittings, press fittings or by inert gas welding. The standard covers the size range from 6 mm to 159 mm outside diameter in two grades of stainless steel from EN 10088-2.

1.1 This European standard specifies requirements for the products listed below for the conveyance of aqueous liquids, including water for human consumption: - seamless and welded non-alloy steel tubes; - end preparation of tube ends for butt welding; - fittings fabricated from the tube; - fittings fabricated from plate or strip. 1.2 This European standard covers a range of tube outside diameters from 26,9 mm to 2 743 mm.
