Q:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:Seamless steel tube with the tube with what is the difference?
Seamless pipe can withstand ultra-high pressure, of course, its wall thickness will increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:What's the actual size of the DN25?
Different materials of steel pipe, nominal diameter of the same, then its outer diameter is the same, diameter = outside diameter -2 times, wall thickness.
Q:What connections are there for concrete filled steel tubular column foundations?
The Liang Duan local widening joint is achieved by the continuous construction of longitudinal steel bars around the steel tube. At the beginning of the creation of additional stirrups should be widened longitudinal reinforced wrap, Liang Duan local widened joints of steel reinforced concrete beam and corbel overlapping transition zone can transmits beam internal force, bending steel bracket in both shear and participation. The node form is used in building engineering in Xiamen. The force transfer path of this joint is clear and reliable, with less welding on site and more convenient for construction. This kind of node passes shear stress through the bracket, and the stress is more concentrated.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.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:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless steel pipe DN15 specification phi 18*3 refers to 3 outer diameter of 18mm B type DN15 seamless steel tube.
Q:Does the seamless steel pipe need rust removal?
Chemical and electrolytic methods are generally used for pickling treatment. The pipeline corrosion only uses chemical pickling, which can remove oxide, rust and old coating. Sometimes, it can be treated as sand blasting after rust removing. Two. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, but its anchor grain is shallow, and easy to pollute the environment.
Q:How do you solder purple copper plate and steel tube?
The copper plate and the steel tube are brazed by brazing or argon arc welding.
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.
Our product range covers include seamless steel pipes for high temperature, heat-exchanger condenser and boiler, cold drawn or cold-rolled precision pipe, fin tubes, special shaped pipes, API series oil well pipes, ASME/DIN/JIS/EN series seamless tubes. Based on strict quality control and scientific management system, the cooperation has successfully obtained International Quality System certificate of ISO9001:2000(12809Q10292ROM), monogram certificates of API 5L (5L-0596) & API 5CT (5CT-0872) and BV certificate (MAT77113-2009)for ship building usage production.
