This article provides an alternative specification for Australian food services. These specifications include:
ASTM A269 “Specification for General Purpose Seamless and Welded Austenitic Stainless Steel Tubing”
ASTM A249 Specification for Austenitic Boiler, Superheater, Heat Exchanger, and Condenser Welded Tubes
AS1528 was revised in 2001 by key stakeholders in the Australian food and pipe industry. AS 1528 is unique in that it covers all relevant fittings except pipes.
All sizes are common grades such as grades 304, 304L, 316 and 316L. AS1528.1 applies to all duplex and austenitic stainless steel grades listed in ASTM A240.
All sizes require fusion-welded products without filler metal. Specifications such as ASTM A270, ASTM A269 and AS 1528 also apply to seamless products.
AS 1528 defines a nominal thickness of 1.6 mm for all outside diameters (OD) and 2 mm for 203.2 mm; other thicknesses may be specified by the purchaser. Standard tolerance + zero, -0.10 mm. Fully negative tolerances are common practice for all pipe sizes, i.e. production in the lower part of the tolerance range. A typical range is 1.52 to 1.58 mm. This tolerance also applies to tube fittings.
* ASTM A554 Tolerance for weld removal conditions. * AS1528 also applies to OD sizes 12.7, 19.0, 31.8, 127.0, 152.4 and 203.2 mm.
All of these pipe specifications specify limits for wall thickness and outside diameter. The inner diameter is not specified separately.
The Australian Food and Beverage Service recommends the following surface finish properties:
Processed products used in the food industry require pipes without welding residues on the inside.
The mechanical properties of various grades of stainless steel commonly used in the food industry are as follows:
At Advanced Materials 2022, AZoM interviewed Andrew Terentiev, CEO of Cambridge Smart Plastics. In this interview, we’ll discuss the company’s new technologies and how they’re revolutionizing the way we think about plastics.
At Advanced Materials in June 2022, AZoM spoke with Ben Melrose of International Syalons about the advanced materials market, Industry 4.0, and the pursuit of zero.
At Advanced Materials, AZoM spoke with General Graphene’s Wig Sherrill about the future of graphene and how their new manufacturing technology will drive down costs to open up a whole new world of applications in the future.

This article provides an assessment of the life of lithium-ion batteries, with a focus on recycling the growing number of used lithium-ion batteries, in order to provide sustainable and closed approaches to battery use and reuse.
Corrosion is the destruction of an alloy under the influence of the environment. Various methods are used to prevent corrosive wear of metal alloys exposed to atmospheric or other adverse conditions.
Due to the growing demand for energy, the demand for nuclear fuel is also increasing, which further leads to a significant increase in the demand for post-irradiation inspection (PVI) technology.
