AS 1528.2:2019 PDF

This Standard specifies requirements for all screwed tube fitting types intended for food processing and hygienic applications. This includes ring-joint types, and trapezoidal thread (ISO type) stainless steel screwed couplings.

The objective of this Standard is to specify the materials, dimensions, and surface finish requirements for welded-type and expanded-type screwed tube fittings, comprising male parts, liners, nuts, blank caps, seals and gaskets in screwed couplings for effecting joins in pipelines in food processing and hygienic applications.

This is Part 2 of a series of Standards for stainless steel tubes and tube fittings for food processing and hygienic applications. The Standards in the series are as follows:

AS 1528.1, Stainless steel tubes and tube fittings for food processing and hygienic applications, Part 1: Tubes

AS 1528.2, Stainless steel tubes and tube fittings for food processing and hygienic applications, Part 2: Screwed tube couplings (this Standard)

AS 1528.3, Stainless steel tubes and tube fittings for food processing and hygienic applications, Part 3: Butt weld tube fittings

AS 1528.4, Stainless steel tubes and tube fittings for food processing and hygienic applications, Part 4: Clamp tube fittings

The revision of the AS 1528 series more closely aligns with other national and international Standards applicable to stainless steel tube and tube fittings for hygienic applications, while retaining a number of requirements that were identified in the prefaces to the 2001 editions as lacking in ASTM and ISO Standards.
