Tubing vs. Pipe 仪表管与工艺管的区别
TUBING 仪表管 Size by OD 尺寸由外径决定 Exact Wall Thickness 精确的壁厚 No thread 不可加工螺纹 Suitable for bending 可弯 PIPE 工艺管 Size by Norminal Bore 尺寸由公称通径决定 WT Is by Schedule 壁厚由承压等级决定 Can make thread 可加工螺纹 Not design for bending 不可弯

Advantages of Tubing vs. Pipe 仪表管的优点
Same Strength but less weight
承压相同的情况下重量更轻
Full wall thickness of tubing is used to contain pressure Wall thickness of pipe needed to contain pressure Extra pipe wall thickness required for threading

Two Main Reasons to Match Materials 材料须匹配的两个主要原因

? Dissimilar metals may cause galvanic corrosion
不同金属之间可能会产生电化学腐蚀

? Ferrules must to be harder than the tubing
卡套硬度必须高于钢管硬度

Galvanic Corrosion (electromechanical)
电化学腐蚀
? Please refer to your Instrument Tube Fitting Installation Manual (page 19)
请参阅管件安装手册Bulletin 4200-B4(第19页)

? Dissimilar Metals – Create a low energy current.
不同的金属间将产生弱电流。

? The low energy current will travel between the two dissimilar metals.
弱电流会在不同的金属间进行流动。

? The metal with more anodic potential will begin to corrode. 电位较高的金属将被腐蚀。 ? Parker does not recommend the use of dissimilar metals.
派克不推荐使用不同的金属材料。

? The only exception is brass fittings on copper tubing.
唯一的例外是黄铜接头配紫铜管。

Typical Corrosion Example
(electromechanical)

典型电化学腐蚀案例
Galvanic corrosion may occur when two different metals are in contact with each other. An example of galvanic corrosion of aluminum in contact with a stainless steel screw after six months exposure in air at a Florida sea coast site
不同的金属相互接触会产生电化学腐蚀。下图是佛罗里达海岸,铝垫片和不锈钢螺栓暴 露在空气中6个月后的腐蚀实例。

Proper Tubing Hardness
正确选择钢管硬度
? For the fitting to properly react with the tubing, the ferrules Must be harder than tubing.
为使接头与钢管正确连接,卡套硬度必须高于钢管 硬度。

? SS tubing should have a maximum hardness of Rb 90.
不锈钢管硬度不得高于Rb 90。

? Rb 80 is recommended.
推荐采用Rb 80的钢管。

Proper Tubing Hardness
选择合适的钢管硬度
? 请将管件安装手册翻到25页

? Please refer to your Instrument Tube Fitting Installation Manual (page 25)

Four Areas for Consideration: 选择时请考虑以下四点: ? Chemical Compatibility
化学兼容性

? System Pressure
系统压力

? System Temperatures
系统温度

? Gas Service

Protecting the Tubing Surface
保护钢管的表面
钢管表面光洁度对卡套接头的密封性能至关重要
? Good quality tube surface finish is essential
高品质的钢管表面光洁度是基本条件。

? Scratches, abrasions, weld seams or roll stampings on the tube surface can create leak paths under the ferrule system.
表面的划伤、磨损、焊缝及压痕都可能会是潜在的泄漏通道。 ? Rule of Thumb:经验方法

? If you can feel a scratch, or weld seam, with your finger nail – it may be deep enough to create a leak path
? 如果您能用手感觉到划痕或者焊缝,那么该缺陷已经足够深而可能导致 泄漏 全面检查 ? Work around 切除质量差的末端 ? Cut off bad end ? Get another piece of tubing 得到一段新的钢管
