Full welding ball valve usually refers to not bolt-bonnet design of body, it be welded by 2 pcs body or 3 pcs body.
Full welding ball valve are widely used in oil & gas process,transportation
industry,water treatment,chemical pipeline for conventional on-off, emergency shut off and quick opening and controlling the flow, especially underground installation.
Fully welded ball valves are especially designed for gas transportation and
storage industries. The fully welded body design can prevent any potential external
leakage from connection of body and bonnet. In addition, the forged body with the
advantages of consistent grain size and even thickness. Thus it inherently eliminates
the conventional casted valve material defects, such as: shrinkage, porosity.
1. Integral Valve Structure
It is welded by forged steel. The forging materials are subjected to ultrasonic examination according to ASME nondestructive flaw detection requirements. The welding slope on the connection face is subjected to liquid penetration examination.
2. Corrosion Resistance And Sulfide Stress Resistance
Certain corrosion allowance is left for the body wall thickness. The carbon steel stem, fixed shaft, ball, seat and seat ring are subjected to chemical nickel plating according to ASTM B733 and B656. In addition, various corrosion resistance materials are available for users to select.
According to customer requirements, the valve materials can be selected according to NACE MR 0175/ISO 15156 or NACE MR 0103, and strict quality control and quality inspection should be carried out during the manufacturing so as to fully meet the requirements in the standards and meet the service conditions in sulfurization environment.
3. Welding Of Transition Pipe
During the manufacturing of the fully welded pipeline ball valve, the transition pipe can e welded for the welding ends valve. The transition pipe can be supplied by users or by our company according to user requirements. Please indicate the transition pipe diameter and length A when placing orders.
