![]() ![]() This requirement addresses the heart of the issue - freedom from sites for product or bacterial build-up.įor more information or advice, contact our team of stainless steel experts in Adelaide. There is also a requirement that the internal surface be smooth, with no lack of weld penetration and no crevices adjacent to welds. Weld BeadĪS1528.1 requires removal of the weld bead (except in the small sizes where the procedure is not possible). This tube specification give limits for OD and Wall Thickness – the Inside Diameter is not separately specified, even although from the hygiene point of view there may be some logic in doing so. ![]() All the above specifications that allow extra ovality for thin wall tube still require the mean OD to be within their respective OD tolerances. Outside DiameterĪS 1528.1 allows ovality of up to double the OD tolerance for all sizes. Slightly wider tolerances apply to the complimentary tube fittings covered by the other parts of AS 1528. A range of between 1.52 and 1.58mm is typical. The all-minus tolerance recognises the usual practice for tube, to all specifications, to be produced towards the lower limit of the tolerance range. Dimensional Tolerances Wall ThicknessĪS 1528.1 specifies standard nominal thicknesses of 1.6mm for all ODs except 2.0mm for 203.2mm OD other non-standard thicknesses can be specified by purchasers. ![]() Another key benefit is the existence of matching specifications for associated tube. Batch traceability marking – considered essential to validate many food and pharmaceutical plants - is mandatory. It is specifically directed at food industry applications, specifying the features necessary to ensure high integrity lines for hygienic applications without requiring high cost additional mechanical testing. It is also the only dimensionally integrated set of tube and fitting standards in the world.ĪS1528.1 is by far the safest option … and the most cost-effective. The standards has been successful in these aims. The aim of AS 1528.3 has been to standardize a hygienic tube fittings for use in dairy and other food and beverage manufacturing, that is effective in maintaining the required food safety standards and that is also readily available at a relatively economical price.
