- 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 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:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
- Welded and seamless pipe standards are ASME B31.10, no go, if you want to force a seamless tube, the request can be seamless for seamless meaning.In addition to that, the cost and difficulty of manufacturing welded pipe is higher than that of seamless tube.
- Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
- The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
- Q:Does seamless steel tube have a bend of 135 degrees?
- Other name: 90 degree elbow, right angle bend, love bend, punching elbow, pressing elbow, mechanism bend, welding elbow, etc..Usage: connect two pipes with same nominal diameter or different pipe, make the pipe bend at 90, 45, 180 degrees and various degrees.Bending radius is less than or equal to 1.5 times the diameter of the elbow. It is 1.5 times larger than the pipe diameter and belongs to the elbow
- Q:How to make the internal tooth of the steel pipe?
- At present, in our country, 300MW or 600MW or more large capacity sub critical and supercritical thermal power boilers are designed or imported abroad. Membrane internal wall tubes are widely used in membrane water wall.
- Q:Galvanized steel pipe DN100 and SC100
- DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
- 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:Can stainless steel pipes spray black paint?
- Yes, after painting, I usually touch hands and paint off in 2 years or so
- Q:What is a tight steel tube?
- JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
The company's main products are: the low-pressure boiler seamless steel pipe, oil casing seamless pipe, ship seamless steel tubes, seamless steel pipe, petroleum cracking, chemical fertilizer equipment, seamless steel tubes, structural seamless steel pipe, seamless steel hollow pumping rod with eight series. According to GB, ASTM, APL5L, AP15CT, DIH, JIS and other standard production seamless steel tubes.
