The thought of designing of limit expansion double flange.
VSSJA - type 2 double flange limit expansion pipe works: loose tube expansion joints after installed on the pipeline, tighten the nut elastic sealing ring, the nut gland depend on each other, the slope under the action of compression in the tube outer ring seal and connection function.When the temperature changes can be in the middle of the joint pipe free of scale, when the foundation sink, the pipe can be skewed, and ensure the sealing with no leakage, thereby the purpose of automatic compensation. VSSJA - type 2 double flange limit expansion pipe expansion joints in buying must strictly according to the design department to provide relevant data.When buying must to manufacturers to provide the following data requirements, a general term for pressure, pipe size, pipe diameter, pipe set, overhead pipeline, directly buried pipeline, the expansion amount of piping expansion joints required, also known as the compensation amount) slip joint pipe and connection way of the expansion joints, can be divided into two methods of flange connection, welding, medium, medium temperature such as offsets, pipes are to be supplied to the manufacturer, the amount of compensation is calculated by the manufacturer. VSSJA - type 2 double flange limit expansion pipe is mainly used in steam pipe, compensation caused by steam pipe heat bilges cold shrink displacement.Advantages: large volume expansion, simple installation, easy maintenance.Features: high voltage, high temperature resistant.Installation note: 1, before installation to loosen pressure plate bolt, install the products to long length, then screw down the bolt diagonal method, don't do partial pressure.2, the expansion pipe should be installed in a straight run of pipe between two fixed bracket, in order to ensure the normal scale and prevent pulled off of products, should be equipped with guide bracket and block.
