This slower cooling rate not only causes an inferior grain structure that is almost as poor as sand-cast anodes, but also necessitates an additional riser to help feed the shrinkage that is catalysed from the change in section.

We have retained aatm pieces for further testing by any interested party, if so desired. These are our key findings. Where such modifications may be appropriate for the casting application, all such changes shall be specifically called-out in the purchaser supplier agreement or contractual document. Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date of production or the revision level of the text standard. Likewise, if a mechanical test bar was machined out of this section of the casting, the results would fall far short of those exhibited by any section of the centrifugally-cast anode.

In the top x-ray of the die-cast anode dark circular shadows depicting sub-surface shrinkage can be seen around the area of the pouring cup, i. You can download and open this axtm to your own computer but DRM prevents opening this file on another computer, including a networked server.

The exact application and usage of discontinuity classifications contained within steel casting reference radiographs must, however, give consideration to the differences in material properties between cast steel and ductile cast iron. Called Type 3 in previous revisions. Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date of production or asmt revision level of the text standard.

If the document is revised or amended, you will be notified by email. 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. E Aastm Radiographs for Heavy-Walled to 12 in. Therefore, generally defining the overall integrity of d186 casting. This chart zstm a comparison in sizes between Specialist Castings Anodes and other common anode sizes.

We have previously been the asttm manufacturer exclusively supplying tubular anodes to the Durichlor 51 Anode company. Astmm radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E 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.

Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. This includes cobalt or equivalent isotope radiation and from e1866 — MV up to 4 — MV X rays- Set of 28 plates nominal 5 by 8 in.

Called Type 3 in previous revisions 1. These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. Severity levels of similar discontinuity categories and energy level range of E or E reference radiographs may alternatively be used, as determined appropriate for the casting service application, if so agreed upon in a purchaser supplier agreement satm Section 1 and 5. However, e1886 size and frequency of these flaws are sufficiently small so their existence does not immediately require the need for the casting to be scrapped.

This standard is also available to be included in Standards Subscriptions. In the image, this area has been de ned as a level 3 defect. This is the same for level 4 and 5 as these flaws are increasing and the design life will be dramatically shortened.

Each volume consists of three categories of graded discontinuities in increasing severity levels, and three categories of ungraded discontinuities.

Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. We have anodes stocked in 2 locations in the USA, utilising purpose-made connectors that have been used in over 1 million anodes over the last 35 years see g 4 for TA2 and TA5A connectors.

These connections can be made in the factory or in the eld. 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.

Some companies, such as the ENI Group simply state their refusal to accept any anodes that are below level 3 and other companies have based their design life on their own experience and installations. 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.
