Q:What's the difference between a rectangular tube and a rectangular steel tube?
The classification of rectangular tube: steel pipe seamless steel pipe and welded steel pipe (tube) hot-rolled seamless tube, seamless tube, seamless tube, welded tube extrusion. The welded square pipe is divided into two parts:(a) according to the process of arc welding - resistance welding tube, square tube (high frequency and low frequency), welding square tube, welding square tube furnace (b) according to the weld - welded square tube, spiral welded pipe.
Q:Can the KBG25 steel tube hold 4 six types of cables?
1 of the six lines of cross-sectional area of about 25 square millimeters, 4 to 100 flat, KBG25 cross-sectional area of about 490100/490=20.4%, just over the specifications, so short distance and less elbow can be worn. However, due to the construction of pipes are generally not standardized, elbow more, and do not use special elbow (site bending), so KBG25 wearing 4, six kinds of cable are more difficult.
Q:How to distinguish seamless pipe and welded pipe?
Most of the welded pipe is six meters, the pipe has obvious welding marks, and seamless pipe wall without welding marks
Q:What is the difference between steel pipe and round steel?
Steel tube or conventional weapons indispensable materials, barrel, barrel to steel pipe manufacturing. The steel pipe can be divided into round tube and special-shaped pipe according to the cross sectional area and shape. Because of the condition of equal circumference, the circle surfaceThe product is the largest and uses round tubes to hold more fluids. In addition, the ring section is subjected to an average force when it is subjected to internal or external radial pressure, so most steel tubes are round tubes.
Q:How much is 4 inches steel tube MM?
The nominal diameter of the 4 inch steel pipe is DN100, that is to say, the diameter of the center of the pipe wall is 100mm.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20#: low carbon steel seamless steel pipe, carbon steel is generally divided into low carbon steel, medium carbon steel and high carbon steel three, 45# steel in carbon steel, low carbon steel is lower than 45#, 45# is higher than that of high carbon steel, seamless steel pipe, such as no special requirements, using 20# seamless steel tube. 20# seamless steel pipe material is 20# steel, the strength is slightly higher than 15#, very little quenching, no temper brittleness. Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing state of the cutting process is better than that of the annealed one. It is generally used to make workpieces with little stress and high toughness.
Q:Hot galvanized steel pipe for use?
The use of hot galvanized steel pipe: mainly used for the delivery of gas, heating.In the greenhouse gas, heating, with the kind of pipe and galvanized pipe, galvanized pipe as a water pipe, produced a lot of rust in the tube, the outflow of water not only pollute the sanitary ware, and mixed with smooth inner wall corrosion caused by bacteria, heavy metal content in the water is too high, serious harm to human health. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries have also issued a civilization, from two, 000 years since the prohibition of galvanized pipe, the current New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.
Q:RC is it welded steel pipe or galvanized steel pipe?
The basic knowledge of wire tubes - wire tubes, SC is welded steel pipe, RC is galvanized steel pipeThe basic wire pipe is the minimum requirement in the steel pipe. For so long, I wonder if you will adopt it
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
