Q:What's the actual size of the DN25?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN (nominal diameter) 250 is generally the industry said 273, welded steel pipe (spiral steel pipe) thickness is generally between 6-8mm, more common.
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
Pile: refers to the use of hammer piling method and pile vibration method, steel casing with valve type pile tip or precast reinforced concrete pile boots into the soil, then pouring concrete (or first in the tube into the cage), while hammering or vibration of a pile side pull tube. The former is called hammer sinking pipe cast-in-place pile, and the latter is called vibrating sinking pipe cast-in-place pile.
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:Stainless steel tube, also known as why tube?
According to the end of the pipe can be divided into light pipe and wire tubeThe tube can be divided into ordinary tube and special thread tube
Q:Galvanized steel pipe DN100 and SC100
Zinc plating, hot dip galvanizing and cold galvanizing, to see the design instructions and design requirements, which will explain
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
It is made up of steel pipe, fastener, base, foot board, safety net and so onSteel pipe rod: generally there are two kinds, an outer diameter 48mm, wall thickness 3.5mm; another kind of outer diameter 51mm, wall thickness 3mm; according to its location and function is different, can be divided into vertical pole, horizontal rod, sweeping rod, etc..Fasteners: fastener is the connection between the steel tube and steel tube, which has three forms, namely the right angle fastener, rotating fastener, butt joint fastener: rectangular fastener for connecting the two vertical pipes, it depends on the friction between the fastener and the steel pipe to transfer load. Swivel fastener: used for connecting two steel tubes intersecting at any angle.
Q:What are the advantages of PVC pipe and galvanized steel pipe?
The steel plastic composite pipe is a product made of two different materials, steel and plastic, and the coefficient of linear expansion between them is quite different. The company is using a new plastic special plastic steel plastic composite pipe company and Nanjing University jointly developed, the polyethylene matrix, adding more than twenty kinds of new materials inside, greatly reduce the plastic coefficient of linear expansion, so as to ensure the steel and plastic composite materials in the reliability of the.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Small and medium-sized cold drawn and hot-rolled are many, large caliber is hot rolling, cold rolled spot less.
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.
