How to clean stainless steel elbow?
2021-11-18
Stainless steel elbow corrosion and rust, usually with special detergent to wash the rust spot. At the same time, more washing should be done in daily life. If there is dust or easy to remove stains on the surface of stainless steel elbow, it is recommended to wash with warm water or weak detergent, or even soapy water. If there are trademarks on the surface of the stainless steel elbow, it can also be washed with weak detergent, but it needs to be washed dry with water after washing.
When installing stainless steel elbow, it can be installed according to the position of use. Usually it can be installed in any position on the pipe. But in order to facilitate the inspection operation, it should be noted that if the medium flow of the stainless steel elbow is upward flow under the longitudinal plate, then the stainless steel elbow can only be installed horizontally. In addition, in the installation of stainless steel elbow, special attention should be paid to the sealing between the elbow and the pipeline, to avoid medium leakage, and then affect the normal operation of the pipeline.
Stainless steel elbows generally do not suffer from corrosion, pitting, corrosion or wear. Stainless steel is one of the strongest building metal materials. At the same time, because of the good corrosion resistance of stainless steel, it can keep the integrity of structural component engineering design for a long time. Chromium-containing stainless steel has high mechanical strength and high ductility, which can meet the requirements of spare parts manufacturing. Normally, oxygen in a metal metropolis reacts to form an oxide film on the surface. This oxide film ensures the corrosion resistance of stainless steel.
The corrosion resistance of stainless steel is affected by alloying elements contained in the steel. Chromium is the essential 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, forming a thin and dense oxide film on the surface of stainless steel, which can avoid further corrosion of stainless steel.
The stainless steel raw material in the stainless steel elbow is the clearance solid solution of chromium, nickel and other elements in -Fe, which should be regarded as the mainstream stainless steel type. The main characteristics of this steel are: non-magnetic austenite arrangement at indoor temperature, low yield ratio, good plasticity, excellent weldability, easy tempering and casting forging. The composition of this steel is characterized by a 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 elbow has excellent corrosion resistance and excellent mechanical technical performance, so it is widely used in mechanical equipment.
