Q:How to set the channel steel into a circle?
Divide the line 16 from 0.1.2.3 to 16. Calculate the two diameter elbow lofting: Yn=r cos alpha when 0 DEG n below 90 DEG Yn=1/2 alpha (d-2t alpha) cosWhen 90 degrees less than or equal to 180 degrees when n < alpha Yn=1/2dcos alphaIn the formula, the Yn--- expansion graph has a circumferential length equal to the curve coordinate value;R--- auxiliary circle radius;D--- diameter of round tube;T--- plate thickness;Alpha n--- auxiliary circumferential equal angle; tube of 300mm diameter,N optional 16 alpha 1=360 degrees, /16=22.5 degrees, 2=45 degrees, 3=67.5 degrees, 4=90 degrees, 5=112.5 degrees, 6=135 degrees, 7=157.5 degrees, 8=180 degreesFormula: Y0=1/2 (d-2t) cos0 degrees =0.5 (d-2t)Y1=1/2 (d-2t) cos22.5 degrees =0.4619 (d-2t)Y2=1/2 (d-2t) cos45 degrees =0.3536 (d-2t)Y3=1/2 (d-2t) cos67.5 degrees =0.1913 (d-2t)Y4=1/2 (d-2t) cos90 degrees =0Y5=1/2 dcos112.5 degrees =-0.1913dY6=1/2 dcos135 degrees =-0.3536dY7=1/2 dcos157.5 degrees =-0.4619dY8=1/2 dcos180 degrees =-0.5d
Q:10kV and below the distribution cabinet in the room, the basic channel should be higher than the indoor ground level? Which specification is clearly defined?
Power distribution cabinet (box), power distribution cabinet (box) and lighting distribution cabinet (box), measuring cabinet (box), is the last stage equipment of power distribution system. Power distribution cabinet is the general term of motor control center.
Q:What does channel 160 type 140*40 steel pipe mean?
Channel steel is a long strip steel with a cross section, and a section shaped steel with a cross section.
Q:Geometrical dimension of channel steel channel 8
GB material. Now a lot of non-standard (lower tolerance. National standard difference 5~7%)
Q:The lift Ii Michihiro 2500 needs to be fitted with large channel steel to withstand 3 tons of weight
2 28 channel steel or 2 25 steel
Q:What is the concept of nonstandard channel steel compared with the national standard channel steel? Is there any difference in size between the national standard channel steel and the material?
Non-standard channel steel, with channel steel waist height, leg width, waist thickness and per meter weight as the standard, non-standard channel steel, mainly in order to not affect the safety quality of the premise of cost saving, in high, wide and thick discount. For example, 12# channel weight per meter 6 meters for 12.059kg, 72.354kg, and 12# 6 if a channel is 48kg, then we call it under 33.3% (1-48/72.354). In our country, most of the steel market has sales of non-standard profiles, this is called "cut foot".
