Fully welded ball valves, also called welded-body ball valves, feature a completely welded body construction. They are designed to serve as stop or shut-off valves in water and gas supply systems, heat and power engineering, housing and municipal services, as well as in process lines at chemical, oil-refining, and pulp-and-paper production facilities. Forging materials undergo ultrasonic examination in accordance with ASME nondestructive testing requirements. The welding slope on the connection face is subjected to liquid penetration inspection. A certain corrosion allowance is maintained for the body wall thickness. The carbon steel stem, fixed shaft, ball, seat, and seat ring are treated with chemical nickel plating according to ASTM B733 and B656. Additionally, a range of corrosion-resistant materials is available to suit specific applications. Valve materials can be selected according to NACE MR0175/ISO 15156 or NACE MR0103 standards based on customer requirements. Strict quality control and inspections are performed during manufacturing to ensure compliance with standards and reliable service in sulfurous environments.
