Notice for special ordering
Please inFROM us of the following operating conditions. We will select the optimum type for you.
1.NOMINAL DIAMETER.TOTAL LENGTH
In case they are predetermined.
2. ConNECTION FITTINGES
Standard and nominal designation of the screws, and the standard, nominal diameter, and pressure rating of the flange.
3. FLUID
Name of fluid, and concentration. If the material of the connection piping is know, the selection of material will not be require.
4. TEMPERATURE AND PRESSURE
On the normal and maximum values. In case there is pressure fluctuation, the range of fluctuation.
5. APPLCATION
Example: thermal expansion/absorption of piping. Isolation of mechanical vibration, etc.
6. SHAPE OF PIPING
Example: U-shape sagging pipe.
7. WHETHER MOVEMENT EXISTS OR NOT
In case there are movements, please give the value of movement, direction, andfrequency.
Also indicate the expected life.
8. MATERIAL OF EACH PART
If there is any designation, please let us know.
9. QUANTITY, DELIVERY
10. OTHERS
Fluid speed, outside environmental conditions( corrosivity, temperature, pressure),amount of small leakage at the time of high vacuum.
The strength of stainless decreases with the rise in temperature. In case the working temperature is high,in order to ensure the safety of the piping obtain a rough indication of the maximum working pressure of the metal hose. Equals the maximum working pressure at room temperature multiply the various temperature coefficients by the following figures.
