Product Description:

1Structure of Seamless  Steel  Pipes

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

 

2、‍‍Main Features of Seamless  Steel  Pipes:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

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: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:Is it good to buy a simple wardrobe or a steel pipe?
Therefore, the simple solid wood wardrobe and steel pipe wardrobe is good or bad, according to personal preferences to set, and that environmental protection seems to have grades, easy to crack
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.
Q:What time what time for gas pipeline steel pipe PE pipe
City network is generally medium, are generally. PE pipe high pressure pipe with building the required distance, is generally used around the high pressure pipe laying (high pressure gas supply capacity, and can play the role of peak shaving), the city zone by the supply voltage to the voltage, residential building regulation boxes of low voltage supply to the users.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
12Cr1MoVG is a kind of material for alloy tubes. The main purpose is to make the steel structure in the boiler, the use temperature of 580 degrees, requiring high temperature resistance steel plate, durable strength, steel plate in the normalized and tempered state delivery. 12Cr1MoV alloy tube is based on high quality carbon structural steel. It is appropriate to add one or more alloy elements to improve the mechanical properties, toughness and hardenability of steel.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
The production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
Q:How can seamless steel tubes be produced?
The material of rolling seamless tube is round tube blank, and the billet is processed by cutting machine to grow about 1 meters, and sent to the furnace by conveyor belt. The billets are heated into a furnace and the temperature is about 1200 degrees celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. When the round billet is released, it should be punched through the pressure piercer. The most common punching machine is a cone roll piercer, which has high production efficiency, good product quality, large perforation and expanding diameter, and can be used in various steel grades. After the perforation, the round tube blank has been successively rolled, rolled or squeezed by three rollers.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
The urban water supply pipeline cleaning is a very necessary work, it can not only improve the transmission efficiency of pipeline to reduce energy consumption, but also to clear the pipeline dirt, remove two pollution, improve water quality, protect the people's physical and mental health.
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.
