Product Specifications

The ASME B16.9 A815 Gr.S31803 seamless concentric reducers delivered to the UAE customer were manufactured with the following specifications:

Manufactured from Gr.S31803 duplex stainless steel, these reducers provide exceptional corrosion resistance, strength, and tensile strength, making them highly effective in harsh environments, including high-pressure and sour service conditions. The material’s superior resistance to pitting and crevice corrosion makes it ideal for use in challenging industries such as offshore drilling and chemical processing.

Quality Assurance and Inspection

We understand that in the pipeline industry, quality is paramount, and this is why we adhere to strict quality control measures at every stage of production. For the UAE order, our comprehensive inspection and testing process included:

Appearance Inspection: Each reducer was thoroughly checked for any defects such as rust, scratches, bending, or any form of physical damage to ensure the products meet both aesthetic and functional standards.

Material Verification: The reducers were manufactured using Gr.S31803 stainless steel, and we guaranteed that the material properties complied with the customer’s specifications, ensuring optimal performance. Specifically:

• Sulfur Content: ≤ 0.025%
• Carbon Content: ≤ 0.23%
• Carbon Equivalent (CE): ≤ 0.43%

Heat Treatment and Solution Annealing: The reducers underwent heat treatment and solution annealing processes to ensure their resistance to hydrogen sulfide-induced stress cracking and to guarantee that they met the NACE MR0175 and ISO 15156 standards for materials used in sour service environments.

Packaging and Delivery

After passing our rigorous inspection process, the reducers were packaged with care to ensure safe delivery. Each product was fitted with protective caps to prevent damage during transit, and the following marking and painting standards were followed:

ASME B16.9 A815 Gr.S31803 seamless concentric reducer marked

• For sizes 3 inches and below, a minimum marking width of 12mm was applied.
• For sizes 4 inches and above, a minimum marking width of 40mm was required.

This attention to detail ensured that the reducers would arrive in perfect condition, ready for immediate use by our customer.

Once the packaging and marking were complete, the reducers were shipped in a timely manner, meeting the agreed delivery schedule and ensuring our customer’s needs were met without delay.
