Five factors affecting the brightness of stainless steel pipe fittings during annealing

Annealing is a heat treatment process in the processing of stainless steel pipe fittings. The pipe is slowly heated to a certain temperature for a sufficient period of time and then cooled at a suitable speed.   The brightness of the product after the production of stainless steel pipe fittings determines the quality of the product. […]

What are the factors that affect the quality of bright annealing of stainless steel pipes?

After annealing the stainless steel pipe, the brightness of the pipe determines the quality of the product. There are many influencing factors. This paper gives the following 5 relatively important factors. The first is whether the annealing temperature is up to the specified temperature. The heat treatment of stainless steel pipes is usually treated by solid […]

Application of stainless steel pipe in petroleum and petrochemical industry

1 Application of Stainless Steel in Petroleum and Petrochemicals The most commonly used classification of stainless steel is classified according to the structure of the steel and can generally be divided into ferritic stainless steel, austenitic stainless steel, martensitic stainless steel, duplex stainless steel, and precipitation hardened stainless steel. In petroleum and petrochemical applications, austenite stainless steel, […]

Application advantages of stainless steel bellows

Stainless steel bellow has many advantages, such as safety, reliability, easy installation, and elegant appearance. In recent years, it has gradually replaced rubber hoses in practical applications. The following describes the advantages of stainless steel bellows. Firstly, it is embodied in high safety and reliability. The stainless steel bellow changes the screw connection process into a […]

Factors Influencing Grain Boundary Corrosion of Stainless Steel pipes

The corrosion of stainless steel pipe is mainly caused by the material properties, surface conditions, medium properties, pH value, temperature, flow rate and time. In addition, the factors affecting the properties of stainless steel include composition, crystal structure and passivation. Membrane and so on. The composition and crystal structure of the stainless steel pipe and the contained […]

Cause of point corrosion in passivation state of stainless steel pipe

Stainless steel pipe in the passivated state will still have a certain ability to react because the passive film is always in a dynamic equilibrium state of dissolution and repair and passivation. When the stainless steel pipe contains the active anion in the environmental media, the equilibrium state is easily destroyed, and the dissolved state at […]
