Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Other commonly used theoretical weight formulas per metre:Thread steel (Kg/m):W=0.00617 * D * D, D - sectional diameter (mm)Fang Gang (Kg/m):W=0.00785 * a * a, a - edge width (mm)Flat steel (kg/m):W= 0.00785 * b * D, B -- edge width (mm) d - thickness (mm)Round steel rod (kg/m),:W= 0.006165 * D * D, D - diameter (mm)
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
Welding: AC arc welding machine welding. Mode 1: apply to the medium of non demanding piping, DN40 steel pipe necking and DN32 steel pipe butt welding, or directly DN32 steel pipe into the DN40 internal welding. 2: the pipeline requirements apply to the inner wall of smooth transition, reducing short circuit welding for DN40x32 suppression of this mechanism are used for connection pipe seamless steel pipe high pressure pipeline connection, no special requirements, not commonly used welded steel pipe. Connection of mechanism fittings is not only costly, but not necessary unless special requirements are required!
Q:What's the actual size of the DN25?
DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)
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:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:What connections are there for concrete filled steel tubular column foundations?
Application of double beam connection node usually uses "I" shape columns and steel bracket which is around the construction technology of a modern steel concrete column girder casting formed in the steel pipe outside through the two structures, the bearing pin four axis and four angles on the common components of stress transfer. The construction technology in the application is usually used at both ends of the stress transfer construction mode, through the four steel bracket to the corresponding shear stress, avoid crack width because the node contact produces clear, delayed cracks, improve anti cracking ability of regional nodes.This node model in the connection when the longitudinal reinforcement without through the tube, without bending the construction can be carried out directly, with easy construction technology, construction control difficulty, the economic benefits of construction at the same time, the advantage of low reinforcement to save. In this joint engineering technology, the key pride is to control the stress transfer of steel bracket.
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:How do you solder purple copper plate and steel tube?
When the copper pipe and the size is not too large, such as 10 mm below the pipe welding, brazing is suggested, with brass solder, such as Wei Odin 201 solder, with supporting solder paste, with a neutral flame welding, the copper plate is heated to about 800 degrees, and then use the solder with 201 Wei Odin 201-F in solder welding, welding wire with melt molding.
Q:What does "HBB" glass steel pipe mean?
Non electrical corrosion, non-magnetic, suitable for single core cable laying, and steel pipe is a magnetic material, special treatment must be taken to prevent the formation of eddy currents.
Q:What materials are used in scaffolding pipes?
Safety net with dense green net, safety net of flame retardant standards GB, and safety net of flame retardant performance detection for lighter lit mesh 12 seconds after leaving the fire, flame retardant, continued burning of not more than 4S. The application of 9MM safety net rope, rope, nylon rope woven, each network should be able to withstand the impact of the national standard 1.6KN test.
