Q:Can the KBG25 steel tube hold 4 six types of cables?
The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
Q:How to descaling galvanized steel pipe?
Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
Q:What are the uses of seamless steel tubes?
A large number of pipes used for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:What's the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:How to make the magnetic steel, can be like a magnet?
Of course, not all materials can be magnetized, austenitic stainless steel will not do.
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:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
Full house scaffold is mainly used in the decoration construction of the single storey workshop, exhibition hall, gymnasium and so on. It consists of vertical pole, cross bar, diagonal brace and scissors support
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
