Double flange type limit expansion joint water supply pipeline selection

Double flange type limit expansion joint is generally accepted solid solution heat treatment, commonly known as "annealing", the temperature range of 1040 ~ 1120 ℃. You can also check through the viewing hole of the double flange type limit expansion joint, the annealed double flange type limit expansion joint should be incandescent form, but did not show softening sagging. In order to avoid presenting micro-leakage, double flange type limit expansion joint maintenance gas should adhere to the inevitable positive pressure, if it is hydrogen maintenance gas, the general requirement is more than 20kBar. The method of review can use the double flange type limit expansion joint in the double flange type limit expansion joint at each joint crack, to see if the gas can run. The place where the air can easily run is the place where the double flange type limit expansion joint enters the pipe and the place where it leaves the pipe, the seal ring in this place is especially easy to wear, so it should be reviewed often and changed often. Double flange type limit expansion joint generally receives solid solution heat treatment, which is "annealing" in plain language, the temperature range of 1040-1120℃.
The double flange type limit expansion joint can be dry, double flange type limit expansion joint to dry; second is into the furnace double flange type limit expansion joint can be too much water residue, special tube if there is a hole above, don't leak water into, double flange type limit expansion joint to otherwise the furnace atmosphere all ruined. The double flange type limit expansion joint should be yes, double flange type limit expansion joint and outside air barrier.
For those who use hydrogen as protective gas, only one exhaust port is through. You are also able to view through the double flange type limit expansion joint viewing hole. The double flange type limit expansion joint in the annealing area should be in incandescent form, but there is no softening sag. In all directions, double flange type limit expansion joint can be freely bent into various angles and radii of curvature with the same softness and durability. The spaced flexible and pliable double flange type limit expansion joint is not hindered or stiffened. The tension of the shaft can withstand more than 6 times of the rated inner diameter. Therefore, the double-flange type limit expansion joint is easy to install, energy efficient and can be used effectively to achieve energy saving.
