Product Description

    Aerosun Corportion is  a global leading  intergrated engineering and solutions suplier for flexible piping.

Aerosun has absolute advantages in the domestic design and manufacture of propane dehydrogenation units with flammable, explosive, toxic and high temperature media and expansion joints for styrene units.Product features: The diameter of the circular expansion joint is from DN40-DN10000mm, the size of the square is unlimited, and the diameter of the overall solution equipment is DN40-DN5500. The maximum pressure of the production equipment can reach 15.5MPa, and the temperature range is -196-1300 . The highest density can reach 10-9.

Aerosun has complete manufacturing and testing equipment, with precision shearing machine, automatic longitudinal weld machine, hydraulic forming machine, vertical lathe, solid solution treatment furnace, nondestructive testing equipment and other devices which are more than 100. Have professional production, detection and testing equipment of perfect raw material physicochemical analysis, stainless steel sheet straight procedure and surface pad pasting, precision blanking, longitudinal seam welding, port sealing, bellows forming, heat treatment, structure piece manufacturing, welding combined device and test assembly device, NDE and so on.

Product function: It is mainly used to compensate the thermal expansion and contraction caused by the temperature change of the pipeline. If the pipe is not completely free to expand or contract when the temperature changes, thermal stress will develop in the pipe. This stress must be considered in the pipeline design, otherwise it may lead to the rupture of the pipeline and affect the normal production. As an important part of pipeline engineering, the expansion joint plays an important role in ensuring the long-term normal operation of the pipeline.

Application areas:
1. Nuclear power:Auxiliary equipment and piping for nuclear islands of nuclear power plants: mechanical penetrations, vessels, pumps, valves, important service water systems (SEC), emergency diesel generator setsEquipment and pipelines of conventional island: nuclear power steam turbine unit, high-pressure cylinder exhaust pipe (GPV cold section), low-pressure cylinder inlet pipe (GPV hot section), low-pressure cylinder extraction pipe (ABP)
2. Petrochemical:The expansion joints specially designed by our company have been widely and successfully used in catalytic cracking, propane dehydrogenation, (poly) ethylene/propylene, styrene, PTA, acid (alkali), desulfurization (nitrogen), oil storage and transportation, etc.
