304 stainless steel pipe is widely used in agriculture, chemicals, building materials, boilers, marine parts, medical equipment, auto parts, and household products, because 304 stainless steel pipe has good corrosion resistance, heat resistance, non-magnetic, Impact resistance, weldability and other characteristics.
However, the 304 stainless steel pipe has good corrosion resistance and does not mean that it will not be rusted by corrosion. If used and stored during use, the 304 stainless steel tube will still rust.
The reason for the rust prevention of the 304 stainless steel pipe is because there is a dense oxide film formed by the alloying elements on the surface, which can effectively block the oxygen contact and prevent further oxidation and rusting. In the daily use environment, attention should be paid to the presence of chloride ions. For example, salt, sea breeze, seawater, sweat, and soil will all contain chloride ions. Chloride ions will erode the dense oxide film of the 304 stainless steel tube. Accelerated corrosion and rust of the 304 stainless steel pipe can even surpass the ordinary carbon steel. Therefore, attention should be paid to the use environment of the 304 stainless steel pipe, and the surface of the 304 stainless steel pipe must be wiped regularly to remove dirt, oil, etc., and be kept clean and dry. This type of 304 stainless steel pipe will not rust corrosion, the service life will be longer.
Gate Valves are called "full-flow" valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
