This type of tube is a welded structural grade tubing which is available as per the size and wall thickness. It is actually more of an economical square bar which is used for applications that have a greater and stronger resistance than the others. It has a dull finish in nature which is not attractive at all but is mostly used for different fabrication projects that are exposed to the chemical, fresh water, and salt water environments. This was just the basic information about these tubes; now let us go into details about its uses and specifications. As mentioned above there are a couple of other places where these tubes are used such as structural support for buildings, bridges, highways, machine parts, sign posts, ornamental usages and much more. They are also used at the industrial sites for support only such as construction, furniture and agricultural ones.
Some Basics to Understand
When it comes to steel, the first thing you need to know about it is that has some sort of grade and type that needs to be understood before you purchase one. For example, if you visit the market, you will get to know various types of steel that are available among which you can enquire about the carbon steel kind. All you need to do is then to match the grade with the one you find in the market and the grade for it is A500 GR B/C. So, in short, there is the grade for every type of steel pipe and tubes out there. The other factor you need to be aware of is the shape of the tube or pipe you need to purchase. Let me also inform you another important factor that the steel tube normally comes in various shapes such as round, rectangle, hexagon, oval, oval with flat sides and much more. However, if you wish to have a customised one then you can speak to the concerned manufacturer and supplier and if it is possible you might get it too.
This was all about the shapes and the grade. Let us now know something more about the sizes. Pipes are mostly measured by inner diameters and the schedule that they have whereas the tubes here are measured by their outer diameters and wall thickness, also known as OD and WT respectively. If you are getting a tube then make sure that you also check about another measurement known as Average Wall Thickness since this covers the average area of the wall thickness taken around the tube. Sometimes people consider another type of measurement which is also known by Minimum Wall Thickness. This type of measurement here determines the minimum thickness of the wall throughout the tube. In the market, normally you get various types of tubing and those types are seamless and welded ones. Seamless normally has no weld seam at all while the welded ones have a visible type of weld seam. There are many other companies that also supply Drawn over Mandrel (DOM) tubing too. This type here is a welded product which is without a weld seam since it is removed out completely. You might find it to be a seamless product but it is a welded tube like the others too. The grades for a hot finished carbon steel tubing is around ASTM A106 GR B/C whereas the common carbon welded ones are ASTM A513 respectively. In case you are in a hurry to get some steel tubes then you should definitely go in for Round Mechanical Tubing, Electric Weld and cold drawn ones which are always available and you do not have to wait like the others to be manufactured and then delivered.
Lastly, all I can conclude by saying that it is the best possible type of tube to buy and if you need a customized one with different length and tubing, then all you need to do is to just send a quote as per your requirements to the concerned supplier and manufacturer and get your tubes delivered in just a span of few days. Hope that the above article has given you an idea about the basic information pertaining to the different steel tubes.
