Which Warehouse is Suitable for Steel Pipe ?

  We all know that steel pipes are easy to corrupt. So when we choose a warehouse to store our steel pipes, what should we pay attention to?   1. Steel products should not be put with acid, alkali, salt and cement which are corrosive. Different kinds of steel should be stacked separately to prevent mixing and corrosion.   2. The site and warehouse for storing steel products should be clean, with good drainage, and away from factories and mines which produce harmful gases or dust. Weeds and other stuff should be removed in order to keep the steel clean.   3. The warehouse should be selected according to geographical conditions, we often adopt ordinary closed warehouse, that is, a roof with walls, tight doors and windows and ventilation device.   4. We should pay attention to the ventilation of the warehouse in sunny days and prevent moisture in rainy days so as to keep the appropriate storage environment.   5. Large-scale structural steel, steel rail, large diameter steel pipe...

Love what I love of steel pipe

  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 year.   Never forget to reflect up...

Difference of seamless carbon steel pipe and welded carbon steel pipe

  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, LSAW steel pipe and so on.    ht...

Transmission safely in winter condition

  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.    http://www.xysteelpipe.com/info/Tr...

If your answer is "yes", there is no doubt that you would like to your steel pipe, like the galvanized steel pipe, with a long life span that will save your money over the long haul.     We all want to use products that will last as it would fail to create headaches and add cost for customers. For building projects, galvanized steel pipe would be one of the options for clients for the reasons:     Zinc layer in galvanized steel pipe would prevent rust for the main pipe. We all know that the galvanization process involves hot-dipping a steel. Thus, once the materials are in use, rusting will still occur, but the zinc layer will rust before the material underneath.     Different supplies made out of galvanized steel. With urbanization and globalization, because of high quality and efficient cost, galvanized stee...

SSAW steel pipe VS LSAW steel pipe

    SSAW steel pipe, short for spiral sub-merged arc welded steel pipe, is a kind of welded steel pipe. LSAW steel pipe, short for longitudinal sub-merged arc welded steel pipe, is also a kind of welded steel pipe. Both pipes are of large diameter, and pipe length can be longer than other steel pipe. Today, we’ll talk about the advantages and disadvantages of SSAW and LSAW.     Outer diameter:     SSAW: 219.1mm-3048mm     LSAW: 219.1mm-1626mm     Wall thickness:     SSAW: 5-25.4mm     LSAW: 8-60MM     Raw material:     SSAW: Steel Coil     LSAW: Steel plate     Because of the different of raw material, thus the length of steel pipes for LSAW is shout, but SSAW steel pipe’s length can be dozens of times as the length for LSAW.     There are many differences between LSAW steel pipe and SSAW steel pipes. Differences are caused by raw material or othe...

Do you really know about SSAW?

    SSAW steel pipe, nickname spiral submerged arc, is made by forming ube centerline hose reel molding angle (adjustable). However, do you really know me? Can you identify me with my family members of seamless steel pipe, ERW steel pipe and LSAW steel pipe?     My special trait is that with the same specification, we can be produced a variety of diameter sizes steel pipe. In addition, the raw materials to adapt to a wider range. With the balance production process, we SSAW steel pipe can avoid the main stress coming from the oil, gas or water when applied in the transportation work.     Of course, my bad behavior is that the poor geometry of the weld length compared to the long straight seam pipe. This may cause crack, slag or porosity. Then, who can own me with the saving money? Actually, class 3 and 4 grade oil and gas transportation can find me with the special design specification.     http://www.xysteelpipe.com/info/Do-you-really-know-...

Galvanized steel pipe is very important to our life

    It is the fact that you're very important to our daily life, dear galvanized steel pipe. We know that life it isn't not like a fairy tale, we often try and fail. Finally, we bring you here in our daily life after year’s hard work. Although there are still lots of questions for you; we can handle it for customers.     Does galvanization really protect pipes?     The answer is "of course". Zinc in steel pipes serves as a sacrificial layer. Thinking about it, the zinc parts would be rust before the metal beneath it if they are exposure in the environment of humid.

We know that cost would be an important factor for customers when we choose a product. Actually, prices are vary and they are depended on your galvanized pipe supplier...

Cold weather with freezing galvanized steel pipe

    Everywhere is snow not just only in wechat or qq. According to the weather forecast, lots of places are frozen weather. Under this situation, it is a bad news for the steel pipe like seamless steel pipe, ERW steel pipe and galvanized steel pipe used for transportation.     The hard freeze forced the closure of a building serving in some residences so that the resident would be difficult to get water from the tap. At the same time, the office in the heart of town or in the residence was among dozens dealing with frozen pipes to deal with the cold weather's damage for various steel pipes. As it turned out, water was streaming from a pipe beneath the ground and it had to be shut down due to the cold weather.     Thus, steel pipes would have special advantages compared with plastic or other pipes. This is because the steel pipes pressure taking is higher than other pipes. Of course, the temperature holding is also better than other pipes. Considering th...

Factors attribute to dielectric corrosion for steel pipe

    Due to the complex elements in soil and water, there is no doubt that different corrosion is occurring in innumerable steel pipes like seamless steel pipe, galvanized steel pipe as well as ERW steel pipe.     How could we figure out the relevant factors attributing to dielectric corrosion for steel pipe and keep it from the faster corrosion? Sara thinks that research for different environment is necessary.     Seawater, for instance, would be much more likely to promote dielectric corrosion than distilled water. Under this situation, we should pay high attention to the high quality of the steel pipe if we know they are produced for the deep sea project.     The temperature of the electrolyte also is a factor - the higher the temperature, the more aggressive the corrosion. In the ground water business, we usually are dealing with relatively cool water temperatures. Thus, different temperature would need different steel pipe equipment for ...
