Brief Introduction of Galvanized Pipe and ERW Pipe

Steel suppliers always play a role of “bridge” between manufacturer and user. Through sales, steel suppliers get a lot of the latest information and intelligence of users, and give feedback to the steel mills at the same time, meanwhile, steel mills can also adjust the production plan and categories to meet market demands better .And customers can also learn information about technology industry and market trends through dealing with steel suppliers .As a supplier, I’ll give you a brief introduction of galvanized pipe and ERW pipe today.

Galvanized pipe has two development phases, the cold galvanized pipe and hot dip galvanized pipe. Due to the requirements of environmental protection, cold galvanized pipe has been forbidden. What we use is mainly hot dip galvanized pipe. Zinc is known as the “skin” of steel, galvanized processing cut off the contact between air and steel pipe, so under the circumstance of anaerobic, steel is not rusty, and extends the service life of steel pipe largely. Besides, Zinc oxide is more intensive to prevent further oxidation. If you keep an eye on surrounding, galvanized steel pipe is used as water pipe and gas pipe, not only for the sake of safety, but also the convenience for construction. Practical application shows that the use of galvanized steel pipe reduce the water and gas waste, since the galvanization steel tube is not easy to broke and cause water and gas leak. Galvanized steel pipe can also be used in petroleum industry; it is very sensitive in the field of detecting oil, because the anti-interference function of zinc coating is very strong. A lot of heating pipes take galvanized pipes as materials. Of course, in the respects of machinery, coal, chemical industry, automobile industry, highway, container, and agricultural machinery manufacturing, galvanized steel pipe can often be seen .At the end, for the daily life, here is a little cleaning tips, do washing off rust with dilute hydrochloric acid.

ERW pipe (Electrical Resistance welding pipe) is a welding way that by taking the electrode pressure after the work piece combination to generate heat through touching with the surface and close region of work piece, with the characteristics of high efficiency, low cost, material saving , easy automation, etc. It is widely used in water supply and drainage engineering, petroleum engineering. It also can be used as pile pipe, structural pipe in the field of bridge, docks, roads, building, etc. With the development of aerospace electronics, automobile, household electrical appliances, ERW pipes are increasingly widely noted.

Above are what we mainly introduced today. Steel pipes are with numerous categories, and it may be difficult to understand all of them. But never mind, our sales team will be patient enough to help you. So contact us if you have any questions.

China’s Steel Industry Executive Summary in March 2014

China is the largest steel manufacturer in the world and it is still in fast growing, not only in Steel products’ output, but also in steel products’ range and quality. Chinese low-end steel products, billets and hot-rolled coils for example, are not favorable as before for foreign importers. Instead, Chinese steel industry is becoming a higher value-added supply base. You will find that China’s steel industry is becoming a whole new entity.

How Many Do You Know about Galvanized Steel and Galvalume Steel?

The best way for anti-rust of steel is hot dip galvanizing and galvalume. Galvanized steel and Galvalume steel is becoming more and more popular in modern building market to fulfill our daily life. Among so many China steel suppliers, Steel from China performs outstanding for the qualified products and good service it services.

Galvanized steel is steel that has gone through a chemical process to keep it from corroding. The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily. The coating also gives the steel a more durable, hard to scratch finish that many people find attractive. For countless outdoor, marine, or industrial applications, galvanized steel is an essential fabrication component. Galvanized steel can be found almost everywhere. Many individuals live in steel frame houses, and buildings are often made with galvanized steel roofs. There are multiple steel parts in cars that help protect them from the weather, and it’s used in many marine applications due to its ability to withstand the salt and the elements. Besides being inexpensive, durable and effective, this metal is also popular because it can be recycled and reused multiple times.

Galvalume sheet steel is a 55% Al-Zn coated sheet steel product that is ideally suited for most types of roofing and siding applications as well as unexposed automotive parts, appliances and miscellaneous applications like furniture, outdoor cabinetry, computer cases, gutters, pipe, etc. Since 1972, over 100 million tons of licensed products have been produced globally. Galvalume sheet steel continues to gain approval by specifiers, architects, building owners and many others due to its versatility, ease of use, aesthetics and long-term performance.

Application of Angle Iron and Galvanized Angle Iron

Angle iron is widely used in building structure and engineering structure, such as house beam, bridge, power transmission tower, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame, cable duct support, power piping, bus bracket installation, as well as the warehouse shelves and so on.

Angle iron is mainly divided into two categories, equal angle iron and unequal angle iron, and the unequal angle iron can be divided into equal thickness and unequal thickness. Photos can be seen in the website Steelfromchina.com.

In order to extend span of service life, there is another angle steel named galvanized angle iron. The advantages of galvanized angle iron are as follows:

1. Low processing costs: the cost of the hot-dip galvanized anti-rust coating is lower than any other paint Coating;

2. Durability: hot-dip galvanized angle iron has the properties of glossy surface, uniform zinc layer, no skipping plate, strong adhesion and strong corrosion resistance. In the suburban environment, standard hot-dip galvanized thickness can keep for 50 years without repair; In urban areas or offshore areas, the standard hot-dip galvanized layer can keep 20 years without repair;

3. Good reliability, the galvanized layer is metallurgical combined with steel, which become a part of the steel surface, thus, the durability of the galvanized coating is more reliable;

4. The high toughness of the galvanized coating: the galvanized layer can form a kind of special metallurgical structure which can bear the mechanical damage when in transporting and using;

5. Comprehensive protection: each section of the work piece can be plated with zinc, even in the cavity, sharp corners and hidden place;

6. Time-saving and labor-saving: the galvanizing process is faster than other coating construction method, and this can save the time for painting after installation on site.
