# EO 高压焊接接头 > EO高压焊接接头是一种广受欢迎的焊接接头类型，且符合复杂的焊接流程对于单个零件的严格标准要求。 所属技术：流体连接 ## 系列介绍 EO焊接接头AS和WAS系列可与EO接头装配连接。该接头材料可选碳钢和不锈钢两种，根据轻重系列不同，其尺寸范围从6mm至38/42mm不等。EO弯管焊接接头的焊接端可与硬管焊接而无需使用O形圈，在焊接之前，需将正确尺寸的螺母按照正确的方向预装配好。在焊接过程中，管端预处理、实际焊接操作、焊接人员的资质认证、后续处理、产品测试及存档等流程可能需要符合相关的标准和法规。 市场： • 冲压设备厂 • 重型机械厂 • 发电厂 • 造船厂 应用： • 适用于通用液压系统。 特征/优势： • EO焊接接头可与任意EO接头装配连接，因此拥有广泛的应用范围。 • 弹性密封圈作为主要的密封元件，以获得连接系统密封的稳定性，因此维护和返修的成本大大降低。 • 即使连续多年在严苛工况下长期工作，该弹性密封EO焊接接头也无需重新拧紧。这也就意味着该连接方式拥有更长的使用寿命，且维护和维修成本均显著降低。 • 即使是装配不到位的EO焊接接头也不会没有预兆地突然断开。通常情况下，接头会发生泄漏以表明装配不到位，用户可以及时发现，并重新拧紧接头。 • EO焊接接头可无限次重复拆装。此特性也使得该连接方式拥有更长的使用寿命并降低了成本。 ## 技术参数 | 参数 | 值 | 单位 | | --- | --- | --- | | 品牌 | Ermeto | | | 应用 | Automotive Process, Chemical Transfer, Construction Equipment, Fuel Transfer, Hydraulics, Manufacturing Equipment, Marine, Material Handling, Mobile Equipment, Oilfield, Packaging, Transportation, Fuel Transfer, Hydraulics | | | 分部 | High Pressure Connectors Europe Division | | | 技术 | Fluid & Gas Handling | | | 行业 | Agriculture, Automotive, Construction, Industrial Manufacturing Equipment, Marine, Material Handling, Transportation | | | 产品类型 | Hydraulic DIN Fittings, Weld Fittings | | | 产品风格 | Buttweld | | | 产品序列 | EO Heavy, EO Light | | | 配置 | Tube to Weld | | | 最大运行压力 | 100 to 630 bar | | | 形状 | Elbow 90°, Straight | | | 连接 1 类型 | Male, 24° Cone | | | 连接 1 尺寸 | 6 to 42 mm Tube O.D. | | | 连接 2 类型 | Male, Metric | | | 连接 2 尺寸 | 10 to 46 mm | | | 符合规格 | DIN, ISO 8434 | | | 与流体类型共同使用 | Hydraulic Fluids, Chemicals, Fuels, Gases, Steam | | | 包括附件 | Pre-assembled with EO-2 Functional Nut, Pre-assembled with Nut and EO-D Cutting Ring, Pre-assembled with Nut and EO-DPR Cutting Ring, Pre-assembled with Nut and EO-PSR Cutting Ring | | | 阀体材料 | Brass, Stainless Steel, Steel | | | 密封类型 | Sealing Edge | | | 密封材料 | n/a | | | 最高环境温度 | 250 °C (Steel), 400 °C (Stainless Steel), 482 °F (Steel), 752 °F (Stainless Steel) | | | 最低环境温度 | -40 °C (Steel), -60 °C (Stainless Steel), -40 °F (Steel), -76 °F (Stainless Steel) | | | 最高流体温度 | 250 °C (Steel), 400 °C (Stainless Steel), 482 °F (Steel), 752 °F (Stainless Steel) | | | 最低流体温度 | -40 °C (Steel), -60 °C (Stainless Steel), -40 °F (Steel), -76 °F (Stainless Steel) | | ## 型号入口（首批） -
