The black steel pipe is a kind of cold rolled products, it can be the shear plate, it also can be a coil. Black steel pipe can be used for various of the final product processing and manufacturing , including containers, trays and toys etc.. After coating the organic coating, black steel pipe becomes the double-sided pure tin electroplating black steel pipe, which shows a good corrosion resistance. What’s more, when it is in the uncoated condition, whether through single cold or two cold rolling steel plate, black steel pipe is very easy to produce rust, double-sided pure tin electroplating black steel pipe is not.

Over the past 20 years the tinplate industry of black steel pipe, in order to maintain the tin plate in the packaging industry status, there has been in competition with several alternative materials, the main alternative material is plastic, wax paper and aluminum. Speaking of double-sided pure tin electroplating black steel pipe which can also be used on food, beverages and other non food uses, because of its corrosion resistance, formability and weldability, is becoming a main kind of black steel pipe type. The double-sided pure tin electroplating black steel pipe is a new kind of black steel pipe. Tinplate generally has different kinds of oil film surface such as the Sn-Fe alloy layer, the pure tin, or the tin oxide layer. Originally, it is the black steel pipe by annealing and hardening after cold rolling production, but the current trend is to lighter and stronger materials, thus leading to the development of the thickness of tin plate. After annealing and second cold reduction, we can get the double-sided pure tin electroplating black steel pipe.

Generally speaking, there are several ways for double-sided pure tin electroplating black steel pipe production, and to produce good black steel pipe is a basic foundation. One, with the 2 stand reversible cold rolling mill instead of the commonly used 5 stand tandem cold rolling mill, there can be an annual output of 200000 tons of black steel pipe. The mill equipped with the most modern device controls the flatness of black steel pipe, which ensures the highest quality of the surface of double-sided pure tin electroplating black steel pipe coming after. To use various grades of hydrogen batch annealing production from Tl to T6, black steel pipe in higher level don’t the need the continuous annealing, but it needs to choose the process and material grade to make sure the double-sided pure tin electroplating black steel pipe can be produces. The improved investment saving is great. Especially at the beginning of entering the market and the higher number of black steel pipe companies will save at least $10000000 a year.

It is no exaggeration to say that our daily life could not work properly without the pipes. In fact, since ancient Rome, human beings have began to use the pipes. But at that time, the lead pipes are harmful for human health. Nowadays, the API steel pipe has shown significant improvement in pipe system. What is the definition of pipe? It is a hollow structure made from different materials including metals and plastics. Black steel pipes are made up of selected steel and they could be used to convey various kinds of materials, such as liquid and gases. You may find that the pipes installed in your house are the plastic types. But when it comes to the industrial purpose, the metal pipes should be chosen to meet the tough working environment.



Steel is allowed to combine with different alloying component. For example, the carbon steel means that the main component is the carbon. The content of carbon could be as high as 1.2%. In addition, the steel could consist of several types of metals including manganese and chromium. While the carbon steel comprise other alloying component, it would be recognized as alloy steel.

The content of the alloying materials are controlled to enhance the advantages of welded steel pipe. For example, the addition of carbon could improve the tensile strength. But at the same time, the ductility would be decreased. So, the manufacturers need to control the content of the additive depending on the customers' expectations. The carbon would make the steel harder. Through the tempering procedure, the hardness could be enhanced. First, the steel is heated to a high temperature for a period, then the steel would be cooled immediately. After the two steps, the tempering is completed.

When you have realized what is black steel pipe, you would have to choose the reliable supplier on the internet. Determine the type of pipes you need and insure the quantities you need. Especially while you are choosing the pipes for heavy industrial purposes, it is a necessity to make sure that the pipe you choose could meet your demand. Generally speaking, API steel pipe offered by reputable distributor could be used for different purposes. Your choice should adhere to the requirements. The reputable distributor would help you to select the proper type even it is hard to find. For more introduction to help you understand steel pipe, please visit: www.xinlinsteel.com
