What is the role of tinplate

What is tinplate? Tinplate , also known as tinned steel or tinned steel, is a thin steel plate with a layer of tin on both sides. The purpose of the coating is to provide corrosion protection and enhance the appearance of the steel. The history of tinplate goes back centuries and its origins can be traced back to ancient civilizations such as China and Egypt. However, it was during the Industrial Revolution in the 18th century that major advances in tinplate production were made. Because of its ability to prevent rust and keep fresh, it has become an important material for canned food. So how is tinplate made? The process involves passing the steel plate through a molten tin bath to ensure an even coating on both sides. The result is a durable and versatile material that combines the strength and stiffness of steel with the protective properties of tin. Tinplate is so attractive because it has many advantages. It acts as a reliable moisture and oxygen barrier, making it ideal for...

One-piece ball valve

Description Although one-piece ball valves and flanged gate valves belong to the same type in the large family of valves, there are obvious differences between them. Among them, the most significant difference is that their closing parts are different. The closing part of a one-piece ball valve is a sphere, which can be rotated around the center line of the valve body to realize the opening and closing of the valve by rotation. The flange gate valve usually uses the gate plate as the closing part, and controls the flow of the medium by the rise and fall of the gate plate. Ball valves play a vital role in piping systems. It is mainly used to cut off, distribute and change the flow direction of the medium. Whether in petroleum, chemical, electric power or other industrial fields, ball valves are one of the indispensable equipment. Its unique design and working principle enable the ball valve to quickly and accurately control the flow of the medium to meet a variety of...

How much does hot dip galvanizing cost?

Hot-dip galvanizing is a widely used metal surface treatment technology, mainly used for anti-corrosion treatment of steel products. By coating the zinc layer on the surface of iron or steel, the sacrificial anode effect of zinc is used to protect the base metal, thereby extending its service life. This technology not only improves the durability of the product, but also enhances the appearance quality. However, the cost of hot- dip galvanizing involves many aspects, and the following is a specific analysis: Raw material cost: The main raw materials for hot-dip galvanizing are zinc alloy and steel. The price of zinc alloy fluctuates according to market conditions, generally between 25,000 and 35,000 yuan/ton, affecting 50-70% of the cost of hot-dip galvanizing. Steel prices will also directly affect production costs. Since the prices of zinc and steel are greatly affected by the supply and demand relationship in the international market, companies need to ...
