In the field of industrial piping and equipment manufacturing, the physical and chemical properties of pipe materials are directly related to product safety and service life. Recently, pipes produced by a certain type of stainless steel pipe brightening and holding furnace were tested and certified by a national metal materials testing laboratory to fully meet and exceed relevant physical and chemical performance requirements.

Testing Agency: Jiuli National Laboratory
Testing Standards: GB/T 4237, GB/T 12770, etc.
Testing Items: Tensile strength, yield strength, elongation, hardness, etc.

Bright Holding Furnace Process Advantages
1. Bright Annealing

Heating in a protective atmosphere prevents oxidation, resulting in a high surface finish.

Maintains the inherent corrosion resistance of stainless steel.
2. Constant Temperature Holding

Precise temperature control ensures uniform microstructure.

Relieves processing stress and improves toughness.
3. Energy-saving Design

Excellent furnace insulation and low heat loss.

Energy consumption is over 15% lower than traditional annealing furnaces.

Applications

Food-grade piping: Fluid pipe production lines

Petrochemical: Chemical fluid transport pipes, extra-long pipes

Semiconductor: PE pipes

"The surface finish and weld quality are very stable, requiring little additional processing." - Technical Director of a pipe factory

Tested and certified by national laboratories, the pipes produced by this stainless steel pipe bright holding furnace not only meet physical and chemical performance requirements but also excel in surface quality, corrosion resistance, energy conservation, and environmental protection.
