高压活接弯头

高压活接弯头（High-Pressure Swivel Elbow）是一种用于高压管路系统中改变流体方向的可旋转连接件，兼具高压密封性和安装灵活性。广泛应用于石油化工、能源装备、船舶液压及重型机械等领域的高压流体输送系统。

高压活接弯头核心特点结构设计

旋转结构：采用精密轴承或球面密封设计，允许接头在高压下360°旋转，便于管路方向调整。

高压密封：多层金属密封环（如Spiral Wound Gasket）或弹簧增强密封结构，耐压可达100MPa以上。

材质多样：主体为不锈钢（316L）、合金钢（如A182 F51）或镍基合金（Inconel 625），适应腐蚀性介质。

接口类型：螺纹（NPT/BSPP）、法兰（ANSI/ASME）或卡套式（Ferrule）连接，支持快速拆装。

高压活接弯头功能优势

动态密封：旋转过程中保持密封性，避免管路扭应力积累。

抗振动疲劳：适用于高频振动的设备（如泵组、压缩机管路）。

免维护设计：预装润滑密封组件，延长使用寿命。

High-Pressure Swivel Elbow Product Overview

The high-pressure swivel elbow is a rotatable fitting designed to change fluid direction in high-pressure piping systems, combining pressure integrity with installation flexibility. It is critical in petroleum, energy, marine hydraulics,  heavy machinery applications.

Key Features

Structure Design

Swivel Mechanism: Precision bearings  spherical seals enable 360° rotation under pressure for alignment adjustment.

High-Pressure Sealing: Multi-layer metal gaskets (e.g., spiral wound)  spring-assisted seals withstand 100MPa+.

Materials: Stainless steel (316L), alloy steel (A182 F51),  nickel alloys (Inconel 625) for corrosive media.

Connections: Threaded (NPT/BSPP), flanged (ANSI/ASME),  ferrule-type for quick assembly.

Functional Advantages

Dynamic Sealing: Maintains leak-proof performance during rotation, reducing pipe stress.

Vibration Resistance: Ideal for high-vibration equipment (e.g., pumps, compressors).

Maintenance-Free: Pre-lubricated seals extend service life.

Typical Applications

Directional changes in oil rig high-pressure manifolds

Multi-port connections for chemical reactors

Flexible routing in marine hydraulic systems

注：根据行业标准，可标注为 "HP Rotating Elbow" 或 "Swivel Joint Elbow"，需注明旋转角度（如90°/45°）及压力等级（如Class 3000）。
