02-SAMSS-012Weld Overlayed Fittings, Flanges and Spool Pieces
The 02-SAMSS-012 Specification is a comprehensive document that outlines the requirements for corrosion resistant alloy (CRA) clad (weld overlayed) fittings, flanges, and spool pieces (pipes) used in the fabrication of clad pipe spools. These spools are essential components used in various industries to transport corrosive or high-temperature fluids while providing protection against corrosion and wear.
The specification covers a range of components, including fittings, flanges, and spool pieces, which are clad with a corrosion-resistant alloy through the process of weld overlaying. This overlaying technique involves applying a layer of CRA material to the surface of the base metal, providing enhanced resistance to corrosion and other forms of degradation.
One significant inclusion in this specification is the coverage of weld overlayed scraper traps. Scraper traps are devices used for the launching and receiving of pipeline scrapers for various purposes, such as cleaning, batching, and inspection. By specifying the requirements for weld overlaying, the specification ensures the scraper traps’ durability and resistance to the harsh conditions of pipeline operations.
Moreover, the specification also permits the use of the clad overlaying process for valves and valve components, expanding its applicability to other critical components in industrial processes.
However, it is important to note that the 02-SAMSS-012 specification has specific limitations. It does not apply to clad line pipes, which are covered under a separate specification, 01-SAMSS-048. Additionally, it does not pertain to the girth welding of clad components for the purpose of fabricating pipe spools. The specification is primarily focused on the requirements related to the overlaying process itself and the components resulting from this process.
In conclusion, the 02-SAMSS-012 specification plays a crucial role in ensuring the quality and reliability of corrosion-resistant alloy clad fittings, flanges, and spool pieces. By adhering to this specification, operators and manufacturers can fabricate clad pipe spools and scraper traps that withstand corrosion, extend service life, and maintain the integrity of critical industrial processes.

FAQs about 02-SAMSS-012 of Weld Overlayed Fittings, Flanges and Spool Pieces
Answer: The 02-SAMSS-012 specification covers corrosion resistant alloy (CRA) clad fittings, flanges, and spool pieces (pipes) used in the fabrication of clad pipe spools. Additionally, it includes weld overlayed scraper traps and permits the overlaying process for valves and valve components.
Answer: CRA clad components provide enhanced resistance to corrosion and wear, making them suitable for transporting corrosive fluids or handling high-temperature and aggressive environments. By overlaying the base metal with a CRA layer, these components offer superior protection, increasing their service life and ensuring the integrity of pipeline systems.
Answer: The weld overlaying process involves applying a layer of corrosion-resistant alloy to the surface of the base metal through welding. This creates a metallurgical bond, effectively clad the components with the CRA material. The benefits of this technique include improved corrosion resistance, wear resistance, and cost-effectiveness compared to using solid CRA materials for the entire component.
Answer: The specification is primarily intended for CRA clad fittings, flanges, and spool pieces used in the fabrication of clad pipe spools. It also allows for overlaying of scraper traps, valves, and valve components. However, it does not apply to clad line pipe nor for the girth welding of clad components for the fabrication of pipe spools.
Answer: The specification includes detailed requirements for the weld overlaying process, material selection, fabrication techniques, and quality control measures to ensure the durability and performance of CRA clad components. Key inspection and testing requirements may involve non-destructive testing (NDT), mechanical testing, and visual inspections to verify the integrity of the clad layers and overall component quality. Adhering to these requirements ensures that the fabricated components meet the industry’s highest standards and perform optimally in corrosive and challenging environments.
