Performance&Characteristic
As a connect unit between the covers of two adjacent equipment,Expansion joint for High Voltage Apparatus mainly used for adjusting the installation,compensate the relative displacement and the movement caused by Expansion and Contraction.General expansion joints always used under the condition of High Stress(Namely,large movement),but this expansion joint always used under the condition of Low Stress(Namely,small movement).
Pressure vessel:
As the holder of the composite apparatus cant bear much pressure,so the structure should be designed to Pressure Balance Type so that the expansion joints can balance the force produced by inside pressure rely on the elastic force of the disc spring to reduce the pressure on the holder.The composite apparatus arefull of expensive media of SF6 gas,annual air leakage≤1,or it will lower the reliability of the products when it operating,if seriously,it will lead to the power cut and the overhaul of the whole system,so the require to the gas tightness is pretty high.
This expansion joint sued as an electric elements,require the inner surface is very smooth and no cusp,or there maybe electric discharge,incluence the insulating property of the products.
Our advantage:
Tieling refinement valve factory since was established large diameter valve have been focused on the road of development.
large diameter gate valves, globe valves, butterfly is our advantage products, company equipment, detection technology to improve, have a good technical team. Strict quality, pay great attention to every detail.
The company mainly exports: Iran, Saudi Arabia, India, Singapore, New Zealand, South Africa, Britain, Germany, Poland, the United States, Mexico and more than 10 countries.
