An overview of the spherical compensator installation position of auxiliary parts.
Piping installation ball spherical compensation, auxiliary installation location is very important.Due to the spherical compensator in laying pipelines borehole, it is a convenient and maintenance.The second is spherical compensator itself needs to have some activity space.Auxiliary parts installed undeserved, can directly affect the normal operation of compensator, causing leakage of medium, the spherical compensator sphere brackets, pipe in mouth serious deformation, even wears away the whole pipe scrap.
Assist spherical compensator are: stents, rolling, spring supports, pipe rolling device, etc.;
Auxiliary installation considerations:
1. The spherical compensator for pipe has a certain amount of compensation can make free telescopic pipe, expansion, shift, etc.The work environment must have enough space.Multiple installations, sphere in sphere installation should leave shall not be less than the sphere of the diameter of the distance between the legs to the limit, in order to avoid sphere influence each other, ensure the normal use of compensator;
2. The pipe connection spherical compensator, generally can be divided into flange connection and socket welding, welding pipe socket position when the auxiliary parts installation and compensator sphere diameter distance shall not be less than 40%, its excess length must be cut off.Spherical compensator deflection displacement has certain defects, pipe flanges are not recommended different heart connection, avoid leakage of sphere;
3. The terrain complex pipe connection, on both ends of the compensator should increase rolling stents and spring.Installation position shall not be less than two times the diameter of the expansion pipe.In order to avoid pipeline compensator for ground friction;
4. Spherical compensator when multiple installations.Must be installed in each sphere below spring support, to ensure that the spherical compensator free activities to ensure the pipeline is not affected by the force, thus extending the service life of the compensator is!
