Gas Pipeline Fully Welded Ball Valve
Gas Pipeline Fully Welded Ball Valve is selected for natural-gas transmission lines requiring full-bore flow, welded-body integrity and long-term sectionalizing service. A gas pipeline fully welded ball valve is tailored around transmission duty, often with full bore, low pressure drop, trunnion support, DBB functionality and butt-weld or flanged ends. Stem extension, drain/vent details, coating and actuator selection depend on station or buried installation.

When to select this design
Natural-gas transmission lines requiring full-bore flow, welded-body integrity and long-term sectionalizing service.
Choose this configuration when the application is specifically gas transmission rather than general industrial welded-body service.
Typical applications
- Natural gas transmission
- Compressor stations
- Metering stations
- Pipeline sectionalizing

Gas Pipeline Fully Welded Ball Valve: design points to confirm.
This is a specific valve construction. Final size, class, material and seat combinations depend on the approved datasheet and design calculation.
| Body construction | This configuration adapts a fully welded trunnion valve to natural-gas transmission duty, emphasizing long-term shell integrity, low pressure drop and remote or station operation. |
|---|---|
| Seat & sealing | SPE/DPE seat philosophy, DBB capability and cavity relief should match transmission operator requirements. Low-emission stem sealing may also be specified for station service. |
| End connection | Butt-weld ends are typical for mainline installation; flanged ends may be used at stations. Full-bore configuration may be specified where pigging is required. |
| Engineering focus | Review pipeline pigging, pressure cycling, line break/emergency shutdown philosophy, actuator sizing, stem extension and drain/vent accessibility. |
| Material selection | Body material should match pipeline design temperature and material class. Trim, seals and bolting must be compatible with dry gas, wet gas or other specified composition. |
| Testing & inspection | Pipeline projects may add DBB verification, fire-safe/emission requirements, actuator functional testing, coating inspection and project-specific documentation to normal pressure testing. |

Construction and maintenance
This configuration adapts a fully welded trunnion valve to natural-gas transmission duty, emphasizing long-term shell integrity, low pressure drop and remote or station operation.
Seat, sealing and torque
SPE/DPE seat philosophy, DBB capability and cavity relief should match transmission operator requirements. Low-emission stem sealing may also be specified for station service.
Piping and installation
Butt-weld ends are typical for mainline installation; flanged ends may be used at stations. Full-bore configuration may be specified where pigging is required.
What to verify before approving the technical offer.
Engineering risk
Review pipeline pigging, pressure cycling, line break/emergency shutdown philosophy, actuator sizing, stem extension and drain/vent accessibility.
Materials and traceability
Body material should match pipeline design temperature and material class. Trim, seals and bolting must be compatible with dry gas, wet gas or other specified composition.
Inspection and testing
Pipeline projects may add DBB verification, fire-safe/emission requirements, actuator functional testing, coating inspection and project-specific documentation to normal pressure testing.
Send the valve datasheet together with the piping class and project valve, material, testing and coating specifications. Missing design inputs should be clarified rather than assumed.
