Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
Absorb movement
Improved thermal stability
Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
Reduce mechanical noise
Compensate for misalignment
Eliminate electrolysis between dissimilar metals
They are ideally suited for hundreds of applications in a wide range of industries, including:
Power Generation
Pulp and Paper
Chemical Processing
Water/Waste Water
Marine
Mining
Heating, Ventilating, and Air Conditioning

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system.
It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed.
Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.

urtain wall architecture. Using spray painting process after processing first, aluminum sheet can be processed into plane, arc and sphere, etc all kinds of complicated geometry.
4. Coating uniformity, colour diversity. Advanced electrostatic spraying technology makes paint adhesion between aluminum plate uniform, color variety, choose space is large.
5. Not defiled, for easy cleaning and maintenance. Fluorine coating film of the viscosity, the surface is difiicult to adhere to pollutants, more good to clean.
6. Installation, construction convenient and quick. Aluminum plate forming in the factory, construction site need not be cut, can be fixed on the frame.
7. Can be recycled, is better for the environment. Aluminum plate can be 100% recovery, is different from the glass, stone, ceramic, aluminum decorative materials, such as recycling salvage value is high.
Range of applications:
1. Building walls, beams, balcony, canopy
2. Airport, station, hospital
3. Conference hall, an opera house
4. Sports venues
5. Reception hall and so on high-rise buildings
