Q:Welded and seamless steel pipe how to distinguish?
Generally, careful observation, can see traces of the weld seam pipe, further is the determination of the polished incision, and then with the file can be seen there is no clear cut, interface traces with the file cleanup to remove when cutting was pasted interface.
Q:Seamless steel tube with the tube with what is the difference?
Seamless steel tube is integrally formed with welded steel pipe steel plate butt welding and welding seam.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffold steel pipe shall be made of 48.3 * 3.6 steel tube. The maximum mass of each steel tube shall not be greater than 25.8kg.Fastener type steel pipe scaffold: for building construction and build, bear the load by the fastener and steel pipe and other scaffolding and support frame, collectively referred to as scaffolding. The fastener is a fastening piece which is fastened by bolts.
Q:What is ND steel pipe?
ND steel also has the ability to resist chloride ion corrosion. ND steel pipe, the main reference indicators (70 degrees Celsius, 50%H2SO4 solution immersion 24 hours), and carbon steel, Japan imported similar steel, stainless steel corrosion resistance compared to higher than these steel grades. Products by domestic refineries and manufacturing units after the use of widely acclaimed, and achieved good results.
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?
The maximum flexural normal stress is calculated as: Sigma =M/ (gamma x*Wnx).Of which: M is the maximum bending moment of the steel tube;Gamma X - the plastic development coefficient of the cross section; for the cross section of the steel tube, 1.15,
Q:What connections are there for concrete filled steel tubular column foundations?
Strengthening ring joint is a more common in the construction of steel pipe concrete column construction, it is to beam column connection through the upper and lower plate reinforcing ring bending force transmission way is through two to strengthen the uniform arrangement between the rings radial ribs and rib structure to connect with the ring the pipe wall at the top of the plate, so as to transfer the shear stress, so as to strengthen the thickness and improve the quality of connection engineering advantage. In the process of engineering construction, according to the construction principle of longitudinal reinforcement of Deng Qiang to control, so that the smaller width of not less than the replacement of the width of the connecting plate 70%, also need to be given due attention in the form of node selection
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The use of scaffold as its height, when the ceiling height below 3.6M, no matter what the ceiling decoration, decorative scaffolding are calculated
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, steel tube is lighter in strength and equal in resistance to bending and torsion. It is an economical cross section steel and is widely used in the manufacture of structural and mechanical parts.
Q:Is the electric pipe used with steel pipe or PVC pipe?
Electric pipe laying is generally divided into the following circumstances:1) the explosion-proof area must be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);2) non explosion-proof area can use KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
Q:How long is the seamless tube?
Seamless steel tube specification: 8-1240 * 1-200mm
