& does relevant recommendations: [in a flexible rubber joint, rummaged through rubber joint sleeve compensator 】 is gongyi city full state pipeline equipment co., LTD. The main business of our company has been made as a special equipment manufacturing license and ISO quality management system certification of qualified companies, the company management concept: the factory in order to "customer needs is our goal" principle, wholeheartedly for the customers with excellent products, reasonable prices, fast delivery cycle, professional technical support and perfect after-sales service. In the future, full state is full of confidence and hope, was determined in a more high quality brand and good service, sincere cooperation with customers at home and abroad, to do the northern area of the thermal compensation smoke duct equipment industry's first brand.


The heat pipe compensator is introduced
Heat pipe is one of the more common type of pipe installation, when put into operation the temperature of the working medium is generally higher, on the whole system will produce a lot of thermal expansion and axial thrust. In order to ensure the safety of the system, shall ensure that the system has enough telescopic allowance. In the construction of general should make full use of natural expansion of the pipeline compensation, when natural compensation can not meet the requirements, to give priority to the compensator to compensate.
Pipe after installation, the pipe due to factors such as medium temperature, climate change heat bilges cold shrink phenomenon, pipeline heat expansion deformation, fracture due to shrinkage occurs, in order to avoid the phenomenon of pipeline damage called thermal compensation. Generally join compensator in section, line for

Heat pipe compensator construction specifications and standards
According to the industrial metal pipeline engineering construction specifications GB50235-2010, installing a heat pipe compensator should be construction in accordance with the following provisions:
1, install thermal pipeline compensator, shall not be welded on the nodal temporary supports, when lifting sling shall not be binding on the nodal;
2, install thermal pipeline compensator, the straight pipe length shall not be less than 100 mm;
3, bronchitis and hanger installation.
Pipe fixed bracket is in order to ensure the reasonable distribution of the heat pipe thermal expansion between the pipeline compensator, set up by the amount of when pipe expansion and contraction caused by the temperature variation, fixed bracket can prevent displacement of the pipeline at this point. With compensating device fixed bracket should be fixed before the pre-tension (compression)

The maximum length of installed heat pipe compensator is calculated
Have to compensate the thermal pipeline should be in the second place high protection, it is in the straight pipe end, 2 it is in the branch pipe. Long no branching heat pipe between two compensator can not set a fixed point, naturally formed by pipe "stagnation" can play a role of protection. The stationary point is a pipeline between two compensator of the fixed point, the pipe diameter, the same buried depth is consistent, the stagnation point and the distance between the two compensator is equal. Natural compensator) compensator (including the corner to the distance between the fixed shall not exceed the maximum length of installed pipeline Lmax, pipeline installation largest length is defined as a set point to the length of the free end (compensator), the length of the friction xu ? shall not exceed the pipes
The maximum length of installation commonly used pipe Lmax. Consideration should be given within 16 KGF/cm squared pressure produced by the ring to the comprehensive effects of stress.
The selection of thermal pipeline compensator
Heat pipe because of the influence of the friction of soil, the actual thermal elongation than overhead and gutter smaller laying pipe hot elongation. Overhead and trench laying elongation: alpha delta tL
During the directly buried installation, because the soil thermal elongation reduction on the impact of friction:
Actual thermal elongation for:
Type of elastic modulus E - steel tube, KGF/cm squared; Alpha linear expansion coefficient of steel tube, 0.0133 mm/m ℃; Delta t - pipe temperature difference; L - the distance between two fixed point m (maximum lengths of the installation). In actual work, the heat pipe thermal elongation, the Danish moller simplified algorithm of the company.
