中亚天然气项目首批

气液联动全焊接球阀交付

贝斯特持续拓展全球能源工程市场

近日，贝斯特集团出口中亚天然气长输管线项主张气液联动全焊接球阀实现出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节造系统，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，线路需逾越荒漠及戈壁地带，持久处于高压输送与显著昼夜温差变动的工况前提下，对阀门的结构不变性、密封靠得住性及持久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，合用于地下直埋及长周期免守护运行工况。

相较于分体式结构，全焊接设计在长输管线利用中可削减潜在衔接界面，从结构层面提升整体密封陆续性与表部环境适应能力，更切合天然气主干线对持久安全运行的工程要求。

针对高压输送系统，阀门在球体加工、阀座密封结构及共同面精度节造方面进行了系统化工艺治理，以保障在Class 600压力工况下的不变密封阐发与作为一致性。

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.

执行系统与远程节造能力集成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关与联锁节造需要。

该类执行系统通常利用于站场集中节造或无人值守管段，通过气液驱动方式实现大扭矩输出与不变作为节造，满足天然气长输系统在垂危堵截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实现整阀联调与作为测试，确

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.

工程造作与批次交付能力Manufacturing and Batch Delivery Capability

在造作环节中，该类大口径高压全焊接球阀涉及多路关键节造工序，蕴含：

 · 大型阀体焊接变形节造与焊后应力治理

 · 球体高精度加工与同轴度节造

 · 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作为一致性验证

该批订单依照工程节点组织出产与检验流程，并以分批方式实现发运，以匹配项目现场施工节拍与装置打算。

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.

面向国际能源工程的系统交付经验Experience in Global Energy Projects

随着全球天然气输送与能源基础设施建设持续推动，全焊接球阀在长输管线、城市供热及工业能源系统中的利用比例持续提升。

在有关工程项目中，阀门产品通常不仅作为单一设备使用，而是纳入整个管线系统的关键节造单元，对造作一致性、批量不变性及工程配套能力均提出较高要求。

依附持续的工程项目实际，贝斯特集团已参加中亚、非洲及北美等多个海表能源与工业管线项目，在产品造作、系统测试及项目交付共同方面形成持续美满的工程服务能力。

With the continuous development of global energy infrastructure, fully welded ball valves are increasingly used in natural gas transmission, district heating, and industrial pipeline systems.

These applications require not only reliable products but also stable manufacturing capacity and engineering-level delivery support.
