Dear costumer, thank you for using SAMA Tools penetrant liquids to control and maintain the quality in your company.
ASME (American Society of Mechanical Engineering) is an engineering company born in 1880 in America in order to solve problems related to steam plants, but then it began to formulate also standards for manufacture and to size properly several types of mechanical plants. ASME Boiler and Pressure Vessel Code (BPVC) is still now an international standard for design, manufacturing and inspection of steam and / or pressure plants, such as the gas section in the production of electricity (nuclear, fossil fuels, etc.).
Section V of the BPVCspeaks about inspection by Non-Destructive Testing, including Penetrant Liquids; in particular, this document looks for requirements of fluorides, chlorides and sulphates content, because these chemicals can trigger dangerous events of corrosion in ferrous materials and the like: for example nickel-based alloys, Austenitic stainless steels and Duplex (said austenitic-ferritic) and Titanium.
ASME compliance of penetrant liquids must be guaranteed by:
a) Number of “batch”. Themixtures are prepared in large-capacity bins, and a number called “batch number” identifies each one. This number identifies uniquely a quantity of material produced in a single operation and having uniform properties (indicated in UNI EN ISO 3452-2). Then, this identification number is printed on each bottle or barrel that come from the mixture related. A sample of this mixture is preserved: this procedure ensures the traceability of the product for many years and it protects from possible objections.
b) Chemical analysis. Every batch must be analysed by a certified laboratory and the test results become part of product and single batch’s documentation. ASME Compliance means ensuring a very low capacity to trigger corrosion (rust) in ferrous materials, high degree of product purity and traceability for long. Our products comply with ASME. The analysis certificates for each batch are available in our company. Please contact us directly or through your dealer to have them.
UNI EN ISO 3452-2:2006
The products purity is very important in the Non-Destructive Testing field. The new UNI EN ISO 3452-2:2006 section 6.12 also speaks about products low in sulphur and halogens. The requirement is quite restrictive and shows as absolute limit maximum 200 parts per million of sulphur and 200 parts per million of chlorides and fluorides. Batch Certificates of analysis carried out so far show that this requirement is satisfied.
Application fields of penetrant liquids
There are numerous application fields of penetrant liquids; our products can be used to detect discontinuities in any type of non-porous material. Concerning the metallurgy, two applications are particularly interesting: in the welding processes control, to detect any discontinuity defects during the process (crater cracks, shrinkage cracks, porosity, slag cracks, undercut), and in the control of elements subjected to fatigue to detect discontinuities, due to repeated and prolonged stresses.
Production process and chemical analysis
In accordance with ASME, internal production procedures ensure the quality of our products. The correct application is assured both by analysing all chemicals in entrance, and by a manager who personally certify the proper execution in the mixtures preparation. All chemical analysis takes place according to very accurate procedures in a laboratory that operates with certified quality management system ISO 9001:2000.
