Q:What are the advantages of PVC pipe and galvanized steel pipe?
Galvanized steel pipe is also used, because some areas require the use of strength. Moreover, the iron and steel industry is a pillar industry, there are some unspoken rules in it.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
Is the wire: also called pipe thread connection, the malleable steel pipe fittings, malleable iron is the thread connection using DN40X32 diameter hoop.
Q:What is the difference between steel pipe and round steel?
Steel tube or conventional weapons indispensable materials, barrel, barrel to steel pipe manufacturing. The steel pipe can be divided into round tube and special-shaped pipe according to the cross sectional area and shape. Because of the condition of equal circumference, the circle surfaceThe product is the largest and uses round tubes to hold more fluids. In addition, the ring section is subjected to an average force when it is subjected to internal or external radial pressure, so most steel tubes are round tubes.
Q:What does "spiral welded steel pipe" DN325*10 mean?
Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
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 is lined pipe?
Is the coating of the inside of the pipe, such as pipe conveying sulfuric acid will corrode, corrosion, but soft plastic pipe, buried in the ground to wall thicker, then you can use the liner and characteristics of hard for using steel pipe laying, sheathed in the steel pipe into the thin plastic tube, it can transport the sulfuric acid,
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
This is according to the "water drawing standards" (GBT50106-2001) in 2.4.2-2 seamless steel pipe, welded steel pipe (straight or spiral seam), brass, stainless steel pipe, pipe diameter should be D diameter * thickness representation (such as D108 * 4 and D159 * 4.5); and the provisions of the habit of acting D with seamless pipe diameter.
Q:The difference between carbon and welded steel tubes
Quality solutionsThe carbon steels we usually refer to include carbon structural steels and carbon tool steelsThe common steel pipe is divided into two kinds: seamless steel pipe and welded steel pipe. The welded pipe of small size is straight welded, and the big size steel pipe is usually spiral welded
Q:Is the electric pipe used with steel pipe or PVC pipe?
In industrial designs, galvanized steel tubes are generally used for laying electric tubes, especially in the case of explosion protection.The benefits of galvanized steel pipe is not easy to damage, can prevent the destruction and damage of environmental forces to a certain extent, a junction box, check for export, export lines and other accessories, construction and maintenance in explosion-proof environment can be exempted from hot work. The disadvantage is higher cost.The PVC tube is less costly, but less impact resistant.
Q:How to perform nondestructive inspection of steel tubes
Including fluorescence, coloring two kinds. Because of its simple equipment and convenient operation, it is an effective method to check the surface defect of magnetic particle inspection. It is mainly used for surface defect inspection of non-magnetic materials.
