      7、每只阀门在出厂前均按设计压力的1.1倍进行氮气密封测试,并按额定工作压力的1.5倍水压进行壳体强度测试

承插焊截止阀

承插焊截止阀是一种采用承插焊接连接方式的截止阀，主要用于截断或调节管路中的流体介质，适用于中高压、小口径（通常DN50及以下）的管道系统。

承插焊截止阀连接特点是管道插入阀体的承口内，通过焊接实现密封与固定，这种结构连接紧密、泄漏风险低，且流阻较小，适合对密封性要求高且不常拆卸的工况。阀芯与阀座采用精密配合，确保截断时的严密性，同时可通过旋转阀杆调节阀芯开度，实现流量的精准控制。阀体材质多为碳钢、不锈钢（如304、316）等，适配水、蒸汽、油品及部分腐蚀性介质，工作压力通常可达42MPa，工作温度范围根据材质不同约为-29℃至550℃，广泛应用于石油、化工、电力等行业的高压管路中。

The socket weld globe valve is a type of globe valve with socket weld connection, mainly used to cut off regulate fluid media in pipelines, suitable for medium-high pressure, small-diameter (usually DN50 below) pipeline systems.

Its connection feature is that the pipeline is inserted into the socket of the valve body sealed fixed by welding. This structure ensures tight connection, low leakage risk, small flow resistance, making it suitable for working conditions with high sealing requirements infrequent disassembly. The valve core valve seat are precisely matched to ensure tightness during shut-off, the flow can be accurately controlled by rotating the valve stem to adjust the opening of the valve core. The valve body is mostly made of carbon steel, stainless steel (e.g., 304, 316), etc., suitable for water, steam, oil some corrosive media. The working pressure can usually reach 42MPa, the working temperature range is approximately -29℃ to 550℃ depending on the material. It is widely used in high-pressure pipelines in industries such as petroleum, chemical industry, electric power.
