When the stainless steel pump surface brown rust (point), people were surprised: that "stainless steel centrifugal pump is not rusty, rust is not a stainless steel pump, the steel may be a problem." In fact, this is a one-sided erroneous view of the lack of understanding of stainless steel. Stainless steel will rust under certain conditions. Stainless steel has the ability to resist atmospheric oxidation --- that is, stainless steel, but also has acid, alkali, salt medium corrosion resistance --- that is, corrosion resistance. However, its corrosion resistance is the size of its own chemical composition of steel, plus the mutual state, the use of conditions and the type of environmental media and change. Such as 304 steel, in the dry and clean atmosphere, there is absolutely excellent resistance to corrosion, but to move it to the beach area, in the sea fog containing a lot of salt, it will soon rust; and 316 steel pipe performance good. Therefore, not any kind of stainless steel pump, in any environment can be corrosion-resistant, non-rusting. Today's latest valid order information free to send! Morning latest buyers information free to send! Punch grab Rob here! Stainless steel is formed by its surface layer of very thin and strong and stable chromium-rich oxide film (protective film), to prevent the continued infiltration of oxygen atoms, continue oxidation, and corrosion resistance. Once for some reason, the film was continuously damaged, the air or liquid oxygen atoms will continue to infiltrate or continuous separation of iron atoms in the metal, the formation of loose iron oxide, the metal surface will also continue to rust. This surface film is damaged in many forms, more common in everyday life are the following: 1, stainless steel surface deposits of deposits containing other metal elements of dust or heterogeneous metal particles in humid air, attachments Condensate with stainless steel, the two together into a micro-cell, triggering electrochemical reactions, the protective film is damaged, called the electrochemical corrosion. 2, stainless steel surface adhesion of organic juice (such as vegetables, noodles soup, sputum, etc.), in the case of water oxygen, organic acids, organic acids for a long time on the metal surface corrosion. 3, stainless steel surface adhesion contains acid, alkali, salts (such as the renovation of the wall of alkali water, lime splashing), causing local corrosion. 4, in polluted air (such as containing a large number of sulfide, carbon dioxide, nitrogen oxides in the atmosphere), the case of condensate, the formation of sulfuric acid, nitric acid, acetic acid point, causing chemical corrosion. The above conditions can cause damage to the stainless steel surface protective film caused corrosion. Therefore, in order to ensure permanent bright metal surface, not rust, we recommend: 1, the stainless steel surface must always be cleaned and scrubbed to remove the attachment, eliminating the external factors that lead to modification. 2, the seafront to use 316 stainless steel, 316 material can resist seawater corrosion. 3, some stainless steel tube on the market chemical composition can not meet the appropriate national standards, up to 304 material requirements. So it will also cause rust, which requires users to carefully choose a reputable manufacturers of products
CA Temporary Fence Introduction:
Temporary Fence is also called
Construction Fence,Removable Fence and Portable Fence. This type was
very popular in Canada, the United States, and some other America
countries.
It is quick to be set up and easy to move and is ideal for restricting
access or containing a site and is commonly seen at construction sites,
public events, as a dog run, or anywhere crowd control is important.
It offers the benefits of affordability and flexibility.
