Application range of unconstrained compensator and spherical compensator
"Unconstrained" is named because there are many constraints on the use of axial contraction joints in the past.
The unconstrained compensator completely eliminates the requirements of the previous axial contraction joint for the guide support spacing of L1 ≤ 4D, L ≤ 4D and L3.
Unconstrained compensator not only has columnar stability, but also has self guiding ability.
Completely eliminate the constraints of 4D, 14D and L3, restrain the device error, have small size, and are safe and reliable, which can eliminate the common problems such as twisting and instability that are easy to occur in the past axial contraction joints, and also bring great convenience to pipeline insulation.
The calculation of the fixed support thrust and the fixed support spacing of the unconstrained compensator is identical to that of the ordinary axial contraction joint.
In order to make the project stable and reliable, the unconstrained compensator is required to be close to the fixed support device, and three guide supports are also required to be set in the space between each fixed support.
The unconstrained compensator can be used for overhead and trench laying of pipelines, or for directly buried laying with compensation. At this time, inspection wells or darkrooms should be set at contraction joints.
The spherical compensator is fixed on the tube plate at one end by expanding the tube, welding and other methods, so that the active state of the cooling medium can be changed to improve the heat transfer coefficient and increase the heat transfer efficiency.
Spherical compensator is a kind of equipment to deal with thermal expansion and cold contraction of pipes, which can be widely used in metallurgy, petroleum, chemical industry, electric power, light industry, textile, construction, national defense establishment and other industries. The detailed uses are as follows:
1. It is used in various pipeline expansion joints of buildings to avoid damage to pipelines due to uneven settlement of foundation, or earthquake and other unexpected reasons.
2. It is used in thermal pipelines to compensate for thermal contraction, and its compensation ability is 5-10 times that of the "Piao" compensator.
3. It is used as a universal joint in the vaporization cooling system of metallurgical equipment (such as blast furnace, converter, electric furnace, heating furnace, etc.).
4. It is used on rocket launching pad and aircraft exhaust equipment to compensate impact contraction.
