美标承插焊球阀

美标承插焊球阀是遵循美国标准（如API、ASME等）设计制造的球阀，采用承插焊连接方式，主要用于中高压管路系统中控制流体的通断。

美标承插焊球阀其结构包括阀体、球体、阀杆、承插焊接口及密封组件等，阀体和球体多选用高强度合金材料（如碳钢、不锈钢），以适应高压工况（常见压力等级为Class 150、300、600等）。承插焊连接通过将管道插入阀体接口后焊接固定，密封性能稳定，适用于中小通径管路（通常DN≤50）。工作时，通过旋转球体90°实现通道的开启或关闭，密封面设计可耐受高压流体冲击，确保无泄漏。

美标承插焊球阀兼具美标标准的规范化、承插焊连接的密封性，以及球阀本身流阻小、操作便捷的特点，广泛应用于石油、化工、天然气等行业的高压管路系统，尤其适合对连接强度和密封性要求较高的场景。

American standard socket weld ball valves are designed manufactured in accordance with American standards (such as API, ASME, etc.). They adopt socket weld connections are mainly used to control the on-off of fluids in medium high-pressure pipeline systems.

Their structure includes a valve body, ball, valve stem, socket weld ends, sealing components. The valve body ball are mostly made of high-strength alloy materials (such as carbon steel, stainless steel) to adapt to high-pressure working conditions (common pressure ratings include Class 150, 300, 600, etc.). The socket weld connection is fixed by inserting the pipeline into the valve body interface then welding, providing reliable sealing performance, is suitable for small medium-diameter pipelines (usually DN≤50). During operation, the channel is opened closed by rotating the ball 90°, the sealing surface is designed to withstand the impact of high-pressure fluids, ensuring no leakage.

This valve combines the standardization of American standards, the tightness of socket weld connections, the advantages of ball valves such as low flow resistance easy operation. It is widely used in high-pressure pipeline systems in petroleum, chemical, natural gas other industries, especially suitable for scenarios with high requirements for connection strength sealing performance
