Q:Seamless steel tube with the tube with what is the difference?
At present there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
With this kind of steel manufacturing products, usually by heat treatment (normalizing and tempering); parts made before use, usually need to go through refining or chemical surface treatment (carburizing and nitriding), surface quenching or high-frequency quenching treatment. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and use of different, such steel can be roughly divided into carburizing, quenching and tempering and nitriding steel three.
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.Strength: the strength of the pipeline in the composition of the alloy and alloy containing the same and the same heat treatment of seamless tube and seamed tube essentially consistent strength. After the tensile test and three-dimensional vibration test, tube tearing almost all occurred in the welding point or away from the heated area where. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, the ASME Boiler and Pressure Vessel Association believes that the seamed tube can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today. The provisions of ASME 100% completely under license by ultrasonic testing pressure tube. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current test tube, the eddy current testing is subject to legal procedures and licensed institutions. Trent's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
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:The plastic pipe and steel pipe difference
The steel plastic pipe is a general term, which includes plastic pipe, plastic lined pipe. Plastic pipe external coating, zinc coated and so on in Shanghai, Fujian, Portland, professional in this area
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The nut body and the junction box are connected at one end by adopting metric fine tooth thread, and the pipe is connected with the pipe, and one end is the same as the straight pipe joint (direct). Withhold the box joint points inside and outside teeth two. The diameter of straight pipe joint is divided into 16mm, 20mm, 25mm, 32mm, 40mm, 50mm.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
SC in principle, it should be called water gas pipe, also called thick wall steel pipe;
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Seamless steel tube branch and seamed two, seamed steel pipe welding is formed, all two can be welded together, if you do not allow the use of seam tube cannot connect.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
High cleanliness requirements for ultrasonic cleaningUltrasonic cleaning principle: the pressure change of ultrasonic wave propagation in the liquid in the liquid cavitation phenomenon strongly, per second produced millions of tiny gas bubbles, these bubbles rapidly in large pressure under the action of not following the violent explosion, impact force and produce strong suction, enough to make the stubborn dirt quickly stripped.
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.
