Here, we delve into the lapping process of a formidable 16” 4500# A182 F92 Parallel Slide Gate Valve currently in our fabrication lineup.

Upon closer inspection, the valve’s appearance has undergone a transformation, the vibrant color giving way to a more subdued hue. This change is not a mere aesthetic shift but a testament to the valve’s journey through seat rings and bypass welding operations, vital components in its construction.

Central to the valve’s structural integrity is the welding process, a linchpin in fabrication. Strict adherence to the prescribed procedures outlined in the Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) is imperative. The careful execution of each welding step ensures the durability and performance of the final product.

Equally paramount are the mandatory and rigorously enforced Heat Treatments, an indispensable phase governing both the heating and cooling processes. Compliance with stringent protocols is not negotiable, especially during Post Weld Heat Treatment (PWHT). The controlled heating and cooling processes ensure structural integrity, mitigating the impact of welding-induced thermal stresses, preventing deformations, and optimizing material strength for reliable industrial components. The resulting changes in the valve’s appearance signify a commitment to enhancing material properties, reinforcing its capability to withstand the rigors of industrial operations.
