Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
Processing method is very simple, I suggest you add blue disk connection, you can not use welding ~ ~ ~!The gas pipe is the best galvanized pipe, mainly play a role in anti-corrosion ~ ~ ~ ~ if you must use seamless connection can.When welding, can open a certain groove, use galvanized material electrode, but the premise is must be welded with seamless tube firmly.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
Q:How is the steel pipe dance installed at home?
According to international competition practice, the standard size of steel tube is 40 mm or 45 mm in diameter, and the 45mm is usually used. The height of the steel pipe is not less than 3.3 meters and not higher than 4 meters. The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe, not seamless steel pipe, seamless steel pipe, welded seam, how can it be called seamless pipe?. Tell you a method: measurement of wall thickness, multi test several points, if each point, that is because it is cold drawn pipe, seamless pipe, hot rolling, wall thickness may% by sample.
Q:Difference between cold rolled steel pipe and common steel pipe
1, from the dimension accuracy above, cold-rolled steel pipe size is good, high precision2. from the outward appearance, the surface of cold-rolled steel pipe is bright, and the surface of hot rolled steel pipe has obvious oxide skin or red rust
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe
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?
Strength design of steel pipe by this formula to calculate the maximum normal stress in the steel pipe should be less than the value (based on your choice of different grades of steel, steel strength design value is not the same, this value can also be found through the design manual of steel structure), meet the requirements, it can meet the requirements of steel pipe under the action of bending moment strength.
Q:What is the process of spiral steel tube production?
Butt welding: the use of advanced double submerged arc welding technology for pre welding, internal welding, external welding. The welded steel tubes are cut into standard lengths using a plasma gage.
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
The specification for steel tubes is the outer diameter multiplied by the wall thickness.Generally speaking, the diameter of the pipe can be divided into outer diameter (De), inner diameter (D) and nominal diameter (DN).
Q:How many fasteners are there in a ton of steel tubes?
In general, 180-200 fasteners per ton of steel pipe.
