Stainless Steel Elbow Material Characteristics and Cleaning

The pipe mouth of the stainless steel elbow is equipped with a lining. Part of the lining is located in the pipe mouth and fixedly connected with the inner wall of the wide mouth. The other part of the inner lining is located outside the nozzle. The inner lining of the product located outside the nozzle is provided with a cut. It is easy to connect the device when the stainless steel elbow is connected with the stainless steel pipe. It can eliminate the tension caused by the pipe joints' tension and has a solid anti-deformation ability. After welding, the joints will not be deformed after long-term use.

Elbows are pipe fittings that change the direction of the pipeline in the pipeline system. According to the angle, 45°, 90°, and 180° are the most commonly used. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°. The elbow materials include cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, non-ferrous metals, and plastics.

Ⅰ. Characteristics of stainless steel elbow raw material

The stainless steel raw material in the stainless steel elbow is a void solid solution formed by chromium, nickel, and other elements in γ-Fe, which should be regarded as the mainstream stainless steel type. The main characteristics of this steel grade are: it has a non-magnetic austenite arrangement at room temperature, its bending strength ratio is low, the plasticity is good, the welding function is good, and it is easy to be trained and cast and forged.

Ⅱ. Cleaning of stainless steel elbow

Usually, when stainless steel elbow fittings rust, special cleaning agents are usually used to clean the rust spots. And it should be cleaned more frequently during daily use. If the stainless steel elbow has dust or stains that are easy to remove, it should be washed with warm water or weak detergent, or soapy water can also be used. Suppose the surface of the stainless steel elbow has a sticky film such as a trademark. In that case, it can also be washed with a weak detergent, but it needs to be washed with water and wiped dry after washing.

The corrosion resistance of stainless steel is affected by the alloying elements contained in the steel body. Among them, chromium is the basic element that provides the corrosion resistance of stainless steel. When the chromium content in the stainless steel reaches about 1.2%, the chromium will deal with the oxygen effect in the external medium to form a thin and dense oxide film on the stainless steel surface. The film can prevent the stainless steel from being corroded more deeply.

Stainless steel elbows will not produce corrosion, pitting, rust, or wear. Stainless steel welded elbows are manufactured by certain processes and standards in actual production to ensure that they can show good value and function in actual work. It can give full play to specific characteristics and importance in practical applications. According to the normal process, exporting to different countries and regions can promote the rapid development and progress of the national economy, which is of great significance to manufacturers.
