How to clean stainless steel elbows?

When stainless steel elbows are rusted, special cleaning agents are usually used to clean the rust spots. And it should be cleaned more often in daily use. If there is dust on the surface of the stainless steel elbow or stains that are easy to remove, it is recommended to clean it with warm water or weak detergent or even soapy water. If there are films such as trademarks on the surface of the stainless steel elbow, it can also be cleaned with weak detergent, but it needs to be cleaned and wiped dry with clean water.

When installing stainless steel elbows, install them according to the use position. Generally, it can be installed anywhere on the pipeline. However, in order to facilitate inspection and operation, it should be noted that if the medium flow direction of the stainless steel elbow is downward and upward of the longitudinal plate, the stainless steel elbow can only be installed horizontally. In addition, when installing stainless steel elbows, pay attention to the tightness between the elbow and the pipeline to prevent medium leakage, which will affect the normal operation of the pipeline.
Stainless steel elbows are generally not corroded, pitted, corroded, and worn. The strength of stainless steel is one of the highest among building metal materials. And because stainless steel has good corrosion resistance, it can maintain the integrity of the engineering design of structural components for a long time. Chromium-containing stainless steel has both high mechanical strength and high ductility, which can well meet the processing and manufacturing requirements of parts. Usually, oxygen in the metal metropolitan environment will react to form an oxide film on the surface. This oxide film can ensure the corrosion resistance of stainless steel.

The corrosion resistance of stainless steel is affected by the alloying elements contained in the steel body. Chromium is the basic element that provides stainless steel with corrosion resistance. When the chromium content in stainless steel reaches about 1.2%, chromium reacts with oxygen in the external medium to form a thin and dense oxide film on the surface of stainless steel, which can prevent stainless steel from further corrosion.

The stainless steel raw material in the stainless steel elbow is an interstitial solid solution of elements such as chromium and nickel in -Fe, which should be regarded as the mainstream stainless steel type.

The main characteristics of this stainless steel are: non-magnetic austenite arrangement at room temperature, low yield strength ratio, good plasticity, excellent weldability, and easy tempering and casting. The composition characteristics of this steel are high content of chromium (17%), nickel (8%-15%) and other corrosion-resistant elements (such as molybdenum, niobium, titanium, etc.).). Therefore, on the one hand, austenitic stainless steel elbows have excellent corrosion resistance and excellent mechanical and technical properties, so they are widely used in mechanical equipment.
