- Q:Are the welded and galvanized tubes the same weight?
- There should be no difference in the weight of the same specifications for the welded pipe and galvanized pipe. The slight difference is that the galvanized pipe should be pickled before galvanizing and must digest some iron and then galvanized. The difference depends on the difference in the process. So the theoretical calculations are the same.
- Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
- Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe
- Q:Where is the difference between seamless steel pipe and welded pipe?
- The steel tube is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
- Q:How to distinguish between steel pipe and spiral pipe material?
- The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
- Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
- The straight seam welding is relative to the spiral welding and the T-shaped welding, and so on.
- Q:What does GALV mean in a steel tube?
- 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:DN80 seamless steel tube, what is the standard thickness?
- Commonly used DN80 seamless steel pipe caliber should be 89mm*4mm.
- Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
- One is thermal expansion on a bar, that is, piercing between the bars and expanding the tube with a little bit of mandrel. The other is to expand the formed tube before it is heated so that the defects in the pipe will be enlarged. Comparatively speaking, the quality of the first kind is better than the second, and you should belong to the second kind. Compared with the original seamless seamless tube, the quality and chemical properties are certainly different. The price will be cheaper, too.
- Q:Is it good to buy a simple wardrobe or a steel pipe?
- Natural nobility, if the quality and the degree of firmness, is the simple steel cloth cabinet is the best. However, because the texture of wood wardrobe, solid wood wood may be used after deformation.
- Q:What is the difference between steel pipe and round steel?
- The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
