Fully Welded Heating Ball Valve, API 6D, A105, 36 IN, 300 LB

Product Name: Fully Welded Heating Ball Valve
Design Standard: API 6D
Body Material: ASTM A105
Size: 36 Inch, DN900
Pressure: PN25, Class 300 LB
End Connection: Butt Welded

Fully Welded Ball Valve, also known as Welded Body Ball Valve, features a fully welded body. These valves are designed to be fitted as stop/shutoff valves in water and gas-supply systems, heat-power engineering, housing and communal services, as well as in process lines at chemical and oil-refining plants, and pulp-and-paper production facilities.
The forging materials are subjected to ultrasonic examination in accordance with ASME nondestructive flaw detection requirements. The welding slope on the connection face is inspected using liquid penetration testing. A certain corrosion allowance is left for the body wall thickness to ensure durability.
The carbon steel stem, fixed shaft, ball, seat, and seat ring are subjected to chemical nickel plating according to ASTM B733 and B656. Additionally, various corrosion-resistant materials are available for user selection.
In accordance with customer requirements, valve materials can be selected based on NACE MR 0175/ISO 15156 or NACE MR 0103. Strict quality control and inspection are carried out during manufacturing to fully meet the requirements of these standards and to ensure suitability for service conditions in sulfurization environments.
