MSS SP-97 ASTM A105 BW forged weldolet for Iranian client

Haihao Group is proud to announce the production and delivery of MSS SP-97 weldolet BW (Butt Weld) fittings forged from ASTM A105 normalized steel for our valued client in Iran. These specialty fittings are engineered to meet stringent industry standards and are compliant with NACE MR0103 specifications, ensuring they are suitable for sour service applications in oil and gas environments.

MSS SP-97 ASTM A105 BW forged weldolet

Product Overview

The MSS SP-97 weldolet is a type of branch connection used in piping systems, designed to provide a secure and robust connection between a larger main pipe and a smaller branch pipe. The “BW” in its designation indicates that it is a butt weld fitting, meaning it is welded directly to the main pipeline, forming a seamless, high-strength connection that minimizes the risk of leaks and ensures the integrity of the piping system.

Material and Standards

1.ASTM A105 Forged Steel: The material used for this weldolet is ASTM A105, a carbon steel specification for forged fittings, flanges, and components used in pressure systems. The “Normalized” condition indicates that the steel has undergone a heat treatment process to improve its mechanical properties, including strength and toughness.

2.NACE MR0103 Compliance: The compliance with NACE MR0103 is crucial for sour service applications, where the presence of hydrogen sulfide (H₂S) in the environment can lead to sulfide stress cracking (SSC). This specification ensures that the material and manufacturing processes are tailored to resist the harmful effects of sour conditions, enhancing the safety and reliability of the fitting.

Heat Treatment and HIC Testing

To meet the rigorous demands of the application, the Weldolet fittings undergo a precise heat treatment process. This treatment enhances the mechanical properties of the fitting, making it better suited for high-pressure and high-temperature conditions. Additionally, HIC (Hydrogen Induced Cracking) testing is performed to ensure that the material can withstand the challenges posed by hydrogen-rich environments. HIC testing assesses the material’s resistance to cracking caused by the absorption of hydrogen, which is critical for applications in sour service.

Applications

The MSS SP-97 weldolet BW fitting is widely used in the oil and gas industry, particularly in systems that transport sour gas or other corrosive substances. The combination of robust material properties, heat treatment, and stringent testing ensures that these fittings provide long-lasting, reliable performance even in the most demanding environments.

Haihao Group is committed to delivering high-quality piping solutions that meet and exceed industry standards. Our expertise in forging, heat treatment, and testing ensures that our products provide exceptional performance and reliability.
