Yangzi Petrochemical conducts equipment shutdown

The first time this year, Yangzi Petrochemical carried out a comprehensive overhaul of the equipment by a partial overhaul. The depth, breadth, and difficulty of maintenance were the highest in the past year. At present, the company's oil refinery has more than 3,000 meters of prefabricated pipelines, and completes more than 70% of the overhaul welding work, orderly makes repair connections, and reduces the impact on the surrounding chemical markets. The picture shows the busy prefabrication site of the company's refinery.

Bright Steel Bar


BRIGHT STEEL BAR


Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.

peeled steel bar processing

Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.

Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.

The advantages of steel bright bars we supply:

1) Big stocks of hot rolled round bars or wire rods as raw materials

2) Heat treating furnaces to adjust the mechanical properties

3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.

4) Multiple packages to avoid broken packages and anti-rusty
