GB 1527-87 Seamless Copper Tube
Seamless copper tubes are tubes that are devoid of a seam or a weld joint. These copper tubes are made using a process that involves pushing a hollow copper rod through a die to form a seamless tube. Due to this lack of a seam, these tubes are highly resistant to corrosion and other kinds of damage. The seamless copper tubes that meet GB 1527-87, sometimes referred to as “Chinese Standard” are made to a rigorous set of standards regarding material composition, finish, and other characteristics.
The material composition and form of these tubes must adhere to the standards established by the “Chinese State standard”. The GB 1527-87 tubes must have a minimum tensile strength of 315MPa as well as a solid yield strength of 242MPa. The material must also have an elongation ratio of 9% minimum. Finally, the chemistry of the material itself must meet the requirements of national standard GB/T 5114.
These GB1527-87 copper tubes must have a smooth surface finish to ensure that the tube does not inevitably corrode when exposed to water or other corrosive elements. The ra value, or roughness average, must be 0.7 microns or less. The copper tubes must also be free of any scratches or other blemishes which could lead to premature corrosion. The surface must also be even and consistent throughout the entire tube. The GB1527-87 copper tubes must also have a round cross section.
The seamless copper tubes that meet GB1527-87 standard not only have higher quality materials, but also better performance when compared to their welded or standard seamless counterparts. Due to their uniformity in size and lack of welds, these tubes demonstrate a higher pressure resistance, particularly when compared to welded pipes. Additionally, the lack of welds also means that each section of the pipe has the exact same properties, thus reducing the chances of cracks developing over time. Finally, due to the higher quality and uniformity of the surface, these pipes are more resistant to corrosion then welded or standard seamless tubes, yielding a higher service life.
Seamless copper tubes that meet the GB 1527-87 Chinese Standard are perfect for applications that require a sure seal, high pressure resistance, higher levels of corrosion resistance, and a longer service life. These pipes are the perfect solution for a wide variety of piping needs, and are available in a wide range of sizes and shapes. Additionally, they are relatively easy to process compared to other types of copper tube, making them easily customizable to specific needs. These qualities make them perfect for applications such as plumbing, heating, cooling, and ventilation.
