Welcome to inquire! Contact: Zhang. Many manufacturers may not be very great importance to suppress the bellows from the factory before the test this step heat pipe compensator, often producing complete installation on delivery to the customer, often there is a problem compensator prices during use, began to search for the origin of the problem. Pressure test can help you verify whether bellows qualified, accurate discovery problem. Today I'll tell you about corrugated compensator pressure test before leaving the factory. Bellows compensation device is piping hot fluid, primarily for paved straight pipe. For hot water, steam, oil medium, by sliding movement of the sliding sleeve external sleeve compensator offer, to achieve thermal expansion compensation. Bellows pressure is applied to medium projects ≤2.5MPa, medium temperature -40 ℃ ~ 600 ℃. Using the new flexible graphite sealing materials loop compensator, which has high strength, low coefficient of friction (0.04 to 0.10), aging, effective, easy to maintain.
