Product Description:

1   Selling building many types of square tube  

Square tube, square tube is a kind of call and rectangular tube, is equal and not equal to the length of steel pipe. Is the strip through the process of processing roll system. In general is the strip through the demolition of the package, flat, curly, welded to form a circular tube, and then rolled into a square tube and then cut into a square tube and then cut into the required length.

Q:Are the welded and galvanized tubes the same weight?
There should be no difference in the weight of the same specifications for the welded pipe and galvanized pipe. The slight difference is that the galvanized pipe should be pickled before galvanizing and must digest some iron and then galvanized. The difference depends on the difference in the process. So the theoretical calculations are the same.
Q:What does "buried steel pipe" 6*2SC100 mean?
The embedded steel pipe 6*2SC100 refers to a welded steel pipe with 2 pipe thicknesses of 6mm and a diameter of 100mm. SC pipe means welded steel pipe. Embedment means pre installation (burial).
Q:Is steel pipe made of profiles?
According to the shape of the cross-section, the steel is generally divided into profiles, plates, pipes and metal products in four categories.Therefore, the steel pipe belongs to the pipe, not the profile.
Q:What is an electric welded pipe (EFW)? Seek help!
According to the operation requirements of the electric welding machine, connect the lead wire and set up the proper welding parameter of the electric welding machine, which can be operated by manual or automatic two input methods.After checking, start the electric welding machine and enter the welding process. When the welding time is reached, the machine will automatically enter the cooling state.When the pipe completely removed after cooling, electric fusion welding machine.Cutting the pipe with the cutting tool of plastic pipe or fine toothed saw with cutting guide device, and making its end face perpendicular to the axis of pipe. Remove the edges of the edges with a knife, scrape the weld area in the pipe or spigot end and clean the weld area.Should use the special fixture as far as possible to secure the components to be connected, and the roundness of the pipe shall not exceed 1.5% of the outer diameter of the pipe, or it should be corrected on the corresponding fixture.
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
Wnx - net sectional modulus of steel tubes, also called net sectional resistance moment. If the section is not weakened, it can be found in the steel sheet of the steel structure design manual. If the section is weakened, it can be calculated by the formula according to the sectional dimension according to the formula of the material mechanics.
Q:What's the difference between straight steel pipe and seamless steel pipe?
Observe whether there is weld seam. Welded pipe without treatment, there are obvious weld, there are bulges, like scars. A better point will shave off the weld, but there is a distinct difference between the eye and the eye. Also a small number of pipe will be processed after cold rolling, surface roughness and accuracy are relatively high, may be counterfeit seamless pipe sales. Careful observation will still show that the pipe wall will have a continuous spiral, metal luster slightly brighter, that is, the original welding seam, metallographic structure and other parts of the difference. To tell the truth, the layman would have to observe that it might be a little difficult.
Q:Fastener type steel pipe scaffold external parts name
Even the wall piece the upright rod is connected with the main structure together, available steel tube, fastener or embedded part. Rigid wall, also can be used as a flexible reinforced wall connecting piece of the tie bar. , 5.The base in the form of plug-in and coat type two, inserted a D1 diameter rod diameter than 2mm, diameter D2 rod diameter than 2mm type jacket.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
Because the zinc has been plated outside the steel tube, the time for oiling or painting outside is omitted, and the construction is more convenient;
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel weldability is very good, general use TIG with J50 welding wire, hand arc welding with J506, J507 and other welding rod
