双卡套接头

即使系統在高震動的情況下運作，螺絲連接也能保證在高壓或真空狀態下有足夠的安全性。

这是通过4点有效的结构细节达到的:

• 双卡套通过它的弹性变形可以减弱整个管道系统的震动。它还可以阻止拧紧弯矩从螺母传递到卡套。
• 双卡套以圆环的形式密封管接头和钢管的挤压面。通过管接头本体孔的锥度双卡套被挤压在钢管上，这样产生了压缩现象，钢管就被紧密的密封。
• 通过螺母细牙的特殊表面处理消除了不锈钢螺纹连接的咬死现象。螺母可以重复的使用。
• 一个长的钢管的插入端确保了精密的位置，很小的制造公差确保了钢管的对齐。

Schwer Fittings Standard cleaning

As standard, the u2-Lok twin-ferrule fittings are supplied free of oil and grease (off) and individually packed in foil. A special multi-stage cleaning process with ultrasonic support removes oil and grease residues as well as loose particles, ensuring that the components meet the basic requirements of the industry.

When using oxygen, certain precautions must be taken to rule out the risk of fire. The cleanliness of the system plays an important role in preventing an oxygen fire. For such applications, we offer fittings in accordance with the "offO2" Schwer Fittings standard. This in-house standard defines the cleaning, assembly and packaging of stainless steel fittings in accordance with ASTM G93 Level C for all components in contact with media.

 Please refer to our more detailed information on the various cleaning standards in the data sheets listed below.
