Haihao Group delivers MSS SP-97 A182 F316 45 degree socket weld latrolet for customers in Singapore

As a comprehensive service provider integrating industry and trade, Haihao Group offers various pipe fitting solutions that meet international standards to global customers. Recently, we delivered a 45-degree socket weld latrolet (A182 F316 material) for an energy project in Singapore. The socket weld latrolet is designed with a special specification of 1″x10″, and the wall thickness is precisely controlled at 23.83mm, meeting the requirements of 3000# high-pressure working conditions. Its structural design strictly follows the dimensional tolerance requirements for socket weld latrolet as stipulated in the MSS SP-97 standard.

Quality inspection of MSS SP-97 A182 F316 45 degree socket weld latrolet

During the product realization process, we ensure reliability through a three-stage quality assurance system:

Raw material verification: For the A182 F316 stainless steel material, a double insurance mechanism of spectral analysis and mechanical property re-inspection is implemented to ensure that the material certificate is completely matched with the physical parameters

Process control: The 45-degree socket weld latrolet adopts a combined process of CNC pipe bending and precision machining. The key welding parts undergo 100% penetration testing (PT) + ultrasonic testing (UT).

Finished product verification: In addition to the regular size spot checks, pressure simulation tests were conducted for each socket weld latrolet, and the pressure values were verified by increasing by 15% in accordance with the ASME B16.11 standard.

It is worth emphasizing that this type of MSS SP-97 A182 F316 45-degree socket weld latrolet performs particularly prominently in the low-temperature working conditions of LNG.
