BLACK ANNEALED SQUARE CARBON STEEL WELDED TUBE AND PIPE

Short Description:

Black annealed steel pipe is a type of steel pipe that has been annealed (heat-treated) to remove its internal stresses, making it stronger and more ductile. The process of annealing involves heating the steel pipe to a certain temperature and then slowly cooling it down, which helps to minimize the formation of cracks or other defects in the steel. The black annealed finish on the steel pipe is achieved by applying a black oxide coating to the surface of the steel, which helps to resist corrosion and increases the durability of the pipe.
