SF steel expansion device

product details
SF steel Telescopic device It is composed of body, sealing ring, gland, expansion short pipe and other main parts. It is added with limit device on the basis of original performance of loose sleeve expansion joint, and double nut is used to lock the maximum expansion. The expansion device can be axially retracted within a certain range, and it can also overcome the offset caused by different axial joints of the pipeline in a certain angle. It can greatly facilitate the installation and disassembly of the valve pipeline, and can freely expand and expand in the allowable expansion amount of the pipeline. Once the maximum expansion amount is exceeded, it will play a limiting role to ensure the safe operation of the pipeline.
Scope of application:
Steel expansion joint has good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and light industry, refrigeration, sanitation, water heating, fire protection, electric power and other basic projects.
Connection mode:
The steel expansion device is suitable for both sides to be connected with flange. When installing, adjust the connection length between the two ends of the product and the flange, tighten the gland bolts evenly in diagonal sequence, and then adjust the limit nut. In this way, the pipeline can freely expand and expand within the scope of expansion, lock the expansion amount, and ensure the safe operation of the pipeline. It is convenient to adjust the size according to the installation site. It can reduce the pressure thrust (blind plate force) of the connected parts and compensate the installation error of the pipeline. The steel expansion joint is mainly used for the loose sleeve connection of the accessories such as pumps and valves. The working pressure is divided into 0.6MPa, 1.0MPa, 1.6Mpa and 2.5MPa.
