Many companies are now specifying that anodes should be supplied that pass an x-ray test to level 1, level 2 or level 3 ASTM E The best way to verify the integrity of the sub-surface structure of a casting is by x-ray.
Historical Version s – view previous versions of standard. At acceptance criteria level 3 the casting may not perform correctly. This standard is also available axtm be included in Standards Subscriptions.
A direct comparison of Centrifugally Cast Tubular Anodes and Die Cast Tubular Anodes
Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels wstm not be needed.
These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. It is the responsibility of the user of this standard to establish appropriate safety and health aztm and determine the applicability of regulatory limitations prior to use.
The x-ray acceptance criteria should and does take in to account both the size, frequency and type of defect present.
The table below represents the most up to date summary for assessing the design life against w186 x-ray level acceptance criteria. By examining the quality of levels 1 to 5 that are displayed by anodes you are able to understand how the theoretical life design of the anode system will be affected. We have previously been the only manufacturer exclusively supplying tubular anodes to the Durichlor 51 Anode company.

Called Type 3 asttm previous revisions 1. Although it is not economically viable to carry out an x-ray test on every anode, it is possible to demand that anodes supplied should pass an x-ray criteria level such as level 2 or better and that a percentage of anodes should be tested.
If an accelerated corrosion test was carried out on the whole anode, then this area would be consumed at a faster rate than the remainder of the anode. This x-ray shows a die-cast anode.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The x-ray image of the die-cast anode above shows a serious casting aw visible as a dark shadow in the connection area and is a real-life sample con rming the di culties encountered with this design.

ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings
Reference radiographs containing ungraded discontinuities are provided as a guide for recognition of a specific casting discontinuity type where severity levels are not needed. Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E This chart shows a comparison in sizes between Specialist Castings Anodes and other common anode sizes.
Following is a list of discontinuity categories, types and severity levels for the adjunct reference radiographs of this standard:. You can find out more about which cookies we are using or switch them off in settings. Each volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities.
Subscription pricing is determined by: This includes cobalt or equivalent isotope radiation and from 2—MV up to 4—MV X-rays- Set of 28 plates nominal 5 by 8 in. However, the size and frequency of these flaws are sufficiently small so their existence does not immediately require the need for the casting to be scrapped. Cancel e86 Post comment.

This slower cooling rate not only astn an inferior grain structure that is almost as poor as sand-cast anodes, but also necessitates an additional riser to help feed w186 shrinkage that is catalysed from the change in section.
SI values are shown for information only. Even though the silicon iron material retains gas porosity, if the anodes are produced to level 3 then there are additional flaws in the manufacturing procedure which are quantifiable and ideally should not be accepted.
This standard is not included in any packages. It should be noted that the type of defect seen on the x-ray and its position in the casting will further influence the design life.
In some applications, reference radiographs for steel castings may not be entirely applicable to ductile cast iron material dependent upon design or other usage criteria.
