LSAW Steel Pipe

 Galvanized pipe generally refers to galvanized steel pipe (GI pipe), which is an important building material, and its advantages and disadvantages need to be considered before using galvanized pipe. Next, it is about the advantages and disadvantages of galvanized steel pipe. Advantages of galvanized steel pipe: 1. Low processing cost: the cost of hot-dip galvanizing and anti-rust is lower than that of other paint coatings. 2. Durable and durable: hot-dip galvanized steel pipe has the characteristics of surface luster, uniform zinc layer, no missing plating, no dripping, strong adhesion and strong corrosion resistance. The anti-rust thickness can be maintained for more than 50 years without repair; in urban or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair. 3. The toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation ...

　　Hot-dip galvanized steel pipes are used in construction, machinery, coal, chemical, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery and other manufacturing industries. 　　The surface of the galvanized steel pipe is welded with hot dip or galvanized steel. Zinc plating can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., it also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, oil heaters, condensation of chemical coking equipment, cooler, coal distillate oil exchanger pipe, trestle pipe pile, and support pipe for mine tunnel, etc. 　　The hot-dip galvanized tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining t...

　　Galvanized steel pipes: In order to improve the corrosion resistance of steel pipes, general steel pipes (black pipes) are galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electric steel zinc. The hot-dip galvanizing galvanized layer is thick and the cost of electro-galvanizing is low. 　　Blowing oxygen welded pipe: used as a steel pipe for oxygen blowing, generally with small diameter welded steel pipe, the specifications are from 8/8 inch to 2 inch. Made of 08, 10, 15, 20 or Q195-Q235 steel strip. For corrosion protection, some are aluminized. 　　Wire bushing: It is also an ordinary carbon steel electric welded steel pipe used in concrete and various structural power distribution projects. The commonly used nominal diameter is from 13-76mm. The sleeve of the wire sleeve is thin, and most of it is coated or galvanized, and a cold bend test is required. 　　Metric welded pipe: The specification is in the form of seamless pipe. The welded steel pipe is exp...

　　Black steel pipe is similar to galvanized steel pipe . Black steel pipe and galvanized pipe all use steel as raw material. And general speaking, galvanized steel pipe is more expensive and more durable since galvanized pipe has a zinc coating while black pipe does not. Galvanized pipe covered with a layer of zinc which makes it have higher ability of corrosion protection and help to prevent the accumulation of mineral deposits that will block the pipe.This will lead to a burst. So galvanized steel pipe is more suitable for carrying water instead of gas. 　　For transportation, galvanized pipe is mainly used for carrying water to supply home and commercial buildings. It is also serve as scaffolding frames because of its rust prevention. Black steel pipe is manufactured as seamless which makes it a better type for gas transportation. It can be used for fire sprinkler system since it can prevent fire better than galvanized pipe. Since it has a dark color surface that is form by iron oxi...

　　Due to the different production process and materials, we know that there is huge difference between galvanized and seamless steel pipe. Today, we will compare these two kinds of steel pipes for their uses difference. 　　For seamless steel pipe, it is used among lots of industries widely. Except the general usage of water, gas, oil, general low pressure fluid line pipe, it can be used among heating oil oil industry in particular, marine oil field oil well pipes, pipelines, chemical coking equipment and so on. 　　For galvanized steel pipe, it has more limit than seamless one. Generally speaking, we would like to make it in the project of fence, balcony guardrail, roads, factories, development zones and so on. 　　When talked about high pressure or high dense medium transportation, we would like to choose seamless steel pipe for the basic guarantee during the whole transmit process. 　　 http://www.xysteelpipe.com/info/Uses-difference-for-SMLS-and-galvanized-steel-pipe-1250-1.htm

    Wearing your out like leather, you're bigger than life. And you're beautiful right where you are; you're perfect with all of your galvanized steel pipe scars. No doubt that you contribute yourself for our daily life with the water, oil and gas transportation. All of use need to say “thank you”.     There are three types of galvanized steel pipe mainly: pre-painted, hot-dipped galvanized, and cold-dipped galvanized. Galvanization would involve coating steel, iron or aluminum with a layer of zinc. Thus, here is the question: which kind of type would be better than others? Of course, the common method is hot-dipping for zinc with 120-500G/M2 which is high quality product, or fully submerging the metal in a bath of molten zinc. Under this situation, hot-dipping is usually preferred over other methods because it produces a thicker, more durable zinc layer.     In addition, when talking about function, galvanized steel pipes have a range of uses, especial...

    Whatever demands you have for your steel pipe supplier, if you need your steel pipe to be long lasting, then galvanized steel pipe coated with a thin layer of zinc would be one of your top choices.     1/2 inch diameter galvanized steel pipe, with connections threaded, the rust accumulation inside the steel pipe would choke down the diameter of the pipe. And this would lead to poor water pressure. Under this situation, it is necessary to have a check for the galvanized steel pipe regularly. Thus it would prolong life-span for the steel pipe. Rust can attack the steel pipe's walls too, making the walls thinner. What should we do for that? A zinc layer would slow down the progress of rust and this would save our money for repairing as well as the replacement. In addition, with a minimum thickness of 50 microns, galvanized steel pipe gives a working temperature of between -10 and +110 °, which has excellent adhesion properties and resistance to abrasion or burst. ...
