We usually referred to the stainless steel used for the production or storage of food containers and processing machinery as the food-grade stainless steel. The so-called “food-grade” generally refers to the material production of the product that meets the standard, or there are requirements for corrosion resistance and heavy metal precipitation(Lead, Chromium, Nickel, Cadmium, Arsenic).…
As we know, according to the content of alloy elements in steel, it can be divided into carbon steel and alloy steel. High carbon steel, often referred to as tool steel, is the steel with a carbon content from 0.60% to 1.70%, mainly used for cutting tools manufacturing. Manganese steel, also known as manganese alloy…
Oil casing is a kind of steel pipe used to support the well wall of oil and gas Wells in the fixed hole. This kind of large caliber pipe can fix the oil and gas well wall or hole to ensure the normal operation of the drilling process and the completion of the whole well.…
The oil casing is a steel tube used to support the walls of oil and gas wells to ensure the normal operation of the well during drilling and after completion. Several sets of casing are used for each well, depending on the drilling depth and geology conditions. The casing can be divided into conduit casing,…
The sucker rod is a crucial component of rod pumping equipment. It connects the upper rod to the pumping unit through a coupling. The plunger of the pumping unit is attached to the sucker. The sucker’s function is to transfer the movement of the ground pumping unit to the downhole oil pump. Thread failure is…
Copper-nickel alloy is also known as cupronickel, is a copper alloy with nickel as the main element. It includes copper-nickel binary alloys and nickel-copper alloys containing other alloys such as manganese, iron, zinc and aluminum. The element copper and nickel can solubilize with each other. When the content of nickel exceeds 16%, the metal surface…
