ASME Section VIII Carbon Steel Oil & Gas Industry Application Elliptical Dished Head Manufacturer from China

1. Weld-Fabricated Dished Head with Strict NDT To Assure Quality:

All Weld-Fabricated Dished Head undergo comprehensive non-destructive testing (NDT), including radiographic testing (RT), penetrant testing (PT), magnetic particle testing (MT), and ultrasonic testing (UT), to ensure structural integrity and reliability.

During PT inspection, our technicians perform a highly detailed, segment-by-segment examination, carefully covering the entire surface to guarantee that even the smallest surface discontinuities are detected. This meticulous inspection process reflects our commitment to delivering safe, high-quality pressure components.

For welded heads, we typically produce stainless steel heads with diameters greater than 1.7 meters, and carbon steel heads with diameters greater than 2.1 meters. With advanced fabrication capabilities and strict inspection standards, we ensure that every product meets stringent customer specifications and performs reliably in high-pressure applications.
