中亚天然气项目首批
气液联动全焊接球阀交付
良固阀门持续拓展全球能源工程市场
近日，良固阀门集团出口中亚天然气长输管线项目的气液联动全焊接球阀完成生产并进入分批发运阶段。
该批产品用于天然气干线截断与站场控制系统，首批口径覆盖DN1000–DN1200
(40″-48″)， Class 600压力等级设计，服务于区域能源输送主干网络中的关键节点。
该项目所对应的管线系统运行环境复杂，线路需跨越荒漠及戈壁地带，长期处于高压输送与显著昼夜温差变化的工况条件下，对阀门的结构稳定性、密封可靠性及长期运行一致性提出了持续性要求。
Recently, the first batch of fully welded ball valves for a Central Asia natural gas transmission project has completed manufacturing and entered staged shipment.
The valves will be used in main gas transmission pipelines and station control systems, covering sizes from DN1000 to DN1200 (40″-48″), designed for Class 600 pressure rating, serving critical nodes of regional energy transmission networks. The project serves a key regional energy transportation network.
The pipeline system operates in harsh environments, crossing desert and plateau regions, with long-distance transmission, high pressure, and large temperature differences between day and night. This places strict requirements on valve structural stability, sealing reliability, and long-term operational consistency.
面向长输干线的结构设计与工程适配Engineering Design for Long-Distance Transmission
产品的整体式全焊接阀体结构，适用于地下直埋及长周期免维护运行工况。
相较于分体式结构，全焊接设计在长输管线应用中可减少潜在连接界面，从结构层面提升整体密封连续性与外部环境适应能力，更符合天然气主干线对长期安全运行的工程要求。
针对高压输送系统，阀门在球体加工、阀座密封结构及配合面精度控制方面进行了系统化工艺管理，以保证在Class 600压力工况下的稳定密封表现与动作一致性。
These fully welded ball valves adopt an integral welded body design, suitable for direct buried pipelines and long-term maintenance-free operation.
Compared with split-body structures, the fully welded design reduces potential leakage paths and improves structural integrity, making it more suitable for natural gas trunk line applications requiring long service life and high safety levels.
For high-pressure service conditions, the valve design includes optimized ball machining, sealing structure, and precision control of mating surfaces to ensure stable sealing performance under Class 600 pressure rating conditions.
执行系统与远程控制能力集成Actuation and Control System Integration
本批产品配套气液联动执行机构，用于长距离管线系统的远程启闭与联锁控制需求。
该类执行系统通常应用于站场集中控制或无人值守管段，通过气液驱动方式实现大扭矩输出与稳定动作控制，满足天然气长输系统在紧急切断与远程调度场景下的响应要求。
阀门本体与执行机构在出厂前完成整阀联调与动作测试，确保机械结构与控制系统在统一工况条件下的匹配性与可靠性。
Each valve is equipped with a pneumatic-hydraulic actuator system, designed for remote operation and interlocking control in long-distance pipeline networks.
This system is widely used in unmanned or centralized control stations, providing high torque output and stable actuation performance for emergency shut-off and remote pipeline management.
Each valve undergoes full assembly testing and actuator calibration before shipment to ensure mechanical and control system compatibility under real operating conditions.
工程制造与批次交付能力Manufacturing and Batch Delivery Capability
在制造环节中，该类大口径高压全焊接球阀涉及多道关键控制工序，包括：
· 大型阀体焊接变形控制与焊后应力管理
· 球体高精度加工与同轴度控制
· 阀座密封副的压力适配与耐久验证
· 整阀高压强度试验与密封测试
· 执行机构联动调试与动作一致性验证
该批订单按照工程节点组织生产与检验流程，并以分批方式完成发运，以匹配项目现场施工节奏与安装计划。
The manufacturing process of large-diameter high-pressure fully welded ball valves involves strict control over key procedures, including:
· Welding deformation control and post-weld stress management
· High-precision ball machining and concentricity control
· Seat sealing performance verification under pressure
· Full pressure and leakage testing of assembled valves
· Actuator functional testing and stroke calibration
The order is executed in batches according to project milestones to match construction and installation schedules.
