Product Description

 

Product Description

Item	Details
Material	Commonly include carbon steel, stainless steel, and some alloy materials, which can be flexibly selected according to different usage scenarios
Size Range	The outer diameter usually ranges from 6 to 168 mm, and the wall thickness is 0.5 - 8 mm. Special specifications can also be customized according to the special needs of customers
Surface Quality	The surface roughness is low, reaching Ra0.1 - 0.3μm, presenting a mirror - like effect with no obvious scratches, pitting, or other defects
Hardness Range	Depending on different materials and annealing processes, the hardness can be controlled between HV100 - 250 to meet diverse processing and usage requirements

 

Precision - rolled BA, namely precision - rolled bright - annealed pipes, are high - quality pipes made through high - precision rolling processes and bright - annealing treatments. During the rolling process, advanced equipment and technologies are adopted, and every process is strictly controlled to ensure that the dimensional accuracy of the pipes is extremely high with minimal deviation. The subsequent bright - annealing treatment is carried out in an environment of protective gas, forming a uniform and dense oxide film on the surface of the pipes. This not only maintains the metallic luster but also enhances the corrosion resistance of the pipes.

Precision - rolled BA has remarkable advantages. In terms of surface quality, the mirror - like surface is not only aesthetically pleasing but also eliminates the need for additional surface treatment processes in subsequent processing. Welding, bending, and other operations can be carried out directly, greatly improving production efficiency. In terms of dimensional accuracy, the high - precision dimensions ensure a good fit during the installation and use of the pipes, reducing problems such as leakage and assembly difficulties caused by dimensional deviations. In terms of corrosion resistance, due to the oxide film formed by bright - annealing and high - quality materials, it can be stably used in various corrosive environments, extending the service life of the product. In terms of mechanical properties, the reasonable processing technology endows the pipes with good strength and toughness, enabling them to withstand certain pressure and external force impacts.
