    Like the famous saying goes that “Love what you love, don’t ask questions”. Actually, even for the steel pipe such as seamless steel pipe, ERW steel pipe, galvanized steel pipe, choose the one you love and let it serve you by complete the transport mission.     Some researches have told human beings that galvanized steel pipe may caused the flow of water during transporting after decade’s use. However, like the human’s organ that may have problems. We should see the benefit of this kind of steel pipe too.     Steel is affordable, strong and readily worked for engineering project, but it will quickly rust if not protected from the effects of moisture. Under this situation, the galvanized steel pipe protected by zinc coating. Thus, it prevents the steel core from corroding by serving as a protective outer layer. This is the galaxy for the zinc galvanized steel pipe and for the replacement after decades would be necessary like human body’s exam every y...

    Even for the same carbon steel pipe, there is the difference of seamless and welded. So how could we choose the suitable one for our engineering project when we go the the market for seamless steel pipe or welded steel pipe?     To determine which kind of category should be used, the best way is to get the specimen for the detail research. For example, generally speaking, we could say that welded carbon steel pipe has “crevice” in the welded part. Under this situation, if your using environment need high pressure taking, you may choose the seamless steel pipe as it is made by hollow steel pipe process which could have better pressure holding than welded carbon steel pipe.     After determining which type of carbon steel pipe is right for your application, or if you need help to determine which you should use, contact Xinyue steel pipe for looking various steel pipes such as seamless steel pipe, ERW steel pipe, SSAW steel pipe, galvanized steel pipe,...

    You would know how important for environment, quality for the impact on steel pipes if you are workers who installing the steel pipe like seamless steel pipe, SSAW steel pipe and so on during projects.     First of all, climate would be one of the fundamental factor affecting the steel pipe’s installation. There is less need to consider the cold weather which would make crack of the steel pipe if we install the steel pipe in tropic zone. Of course, for arctic pole, the equipment of steel pipe would be higher quality than general steel pipe’s.     In addition, make sure the weight of your load is evenly distributed. There is no doubt that evenly road would benefit for the life insurance of the steel pipe. If your product steel pipe shifts on uneven roads, it’ll make it more difficult to control the whole balance of the steel pipe. That is why we would see that the workers would dig the road and try to balance it before installing the pipes here. ...

　　There are 9 kinds of weling process of Chinese welded steel pipe: 　　1.High frequency resistance welding 　　Using the skin effect of high frequency current and the proximity effect, the edge of the strip of steel billet is quickly heated to reach the molten state, and the molten metal is squeezed and pressed by the squeezing roller to achieve welding. 　　2.Submerged arc welding 　　Arc welding arc welding method in the coverage of the flux. The weld metal pool is solidified into a weld under the protection of the flux coating, and the flux melt layer cools to the slag shell over the outer surface of the weld. 　　3.Tungsten inert gas welding (TIG) 　　The use of pure tungsten or activated tungsten (thorium tungsten, cerium tungsten, etc.) as the electrode of the inert gas welding tungsten inert gas shielded welding, the English referred to as TIG welding.

　　First, the station open-air, buried seamless line pipe and equipment construction and environmental protection control requirements. 　　Coating can be used for construction coating, brushing, roller coating and other means. Before construction, except for the front coating surface to be clean and dry, but also pay attention to the substrate temperature is higher than the dew point temperature above 3 ℃, so as to avoid condensation of the substrate adhesion of paint. In general, at a relative humidity of less than 85%, the lowest substrate workable temperature is about the same as the ambient temperature, so construction can be done with less than 85% relative humidity. In addition, the two-component epoxy paint, such as the temperature is below 5 ℃, due to the curing reaction is basically stopped, so the construction can not be carried out. 　　Second, anti-corrosion construction safety requirements and requirements 　　1, Safety technical requirements 　　(1) All personnel particip...

    LSAW, short for Longitudinal Submerged Arc Welded steel pipe, was invented in 1940.     It adopt a new welding method, welding hand in front of it and the same place it is to protect the use of slag, but this residue is not a skin electrode medicine, is dedicated melting out of the welding flux.     The welding system consists of a funnel drug loading of the welding flux through a pipeline to be welded to the front. The second difference is the use of welding, using wire, because the wire can be continuously sent; electrode, we gotta burn a welding electrode head and gave a throw, and the operation was suspended, ready for welding and then welding the weld seam.     http://www.xysteelpipe.com/info/A-guide-to-the-history-of-LSAW-Steel-Pipe-741-1.htm

    HSS, short for hollow structural section, is a type of steel pipe with a hollow tubular section. The term is used predominantly worldwide.     HSS steel pipe can be circular, square, or rectangular hollow sections, although other shapes such as elliptical are also available. HSS is only composed of structural steel.     HSS is sometimes mistakenly referenced as hollow structural steel. Rectangular and square HSS are also commonly called tube steel or structural tubing. Circular HSS are sometimes mistakenly called steel pipe,although true steel pipe is actually dimensioned and classed differently from HSS. (HSS dimensions are based on exterior dimensions of the profile; pipes are also manufactured to an exterior tolerance, albeit to a different standard.) The corners of HSS are heavily rounded, having a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.     In the UK, or other countri...
