Q:What's the difference between a rectangular tube and a rectangular steel tube?
Rectangular tube is a kind of hollow long strip steel, also known as flat tube, flat square tube or square flat tube (Gu Mingsiyi). A large amount of pipe used to transport fluids, such as petroleum,Natural gas, water, gas, steam, etc., in addition to bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:How can seamless steel tubes be produced?
Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Q:What does the diameter of a steel pipe project mean?
Suppose we specify a standard that defines the nominal diameter of the same steel tube as G-1, then this G-1 is the same as DN50.I hope it doesn't make you any more confused, huh?. If you still don't understand, keep in mind that the nominal diameter is neither outside nor inside diameter.
Q:What are the uses of welded steel pipes?
Ordinary carbon steel wire bushings (GB3640-88) are industrial and civil construction, installation of machinery, equipment and other electrical installation works for the protection of electric wire.
Q:Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?
SC is welded pipe, not galvanized pipe, RC is galvanized pipe, MT is lined pipe laying
Q:What is ND steel pipe?
ND steel also has the ability to resist chloride ion corrosion. ND steel pipe, the main reference indicators (70 degrees Celsius, 50%H2SO4 solution immersion 24 hours), and carbon steel, Japan imported similar steel, stainless steel corrosion resistance compared to higher than these steel grades. Products by domestic refineries and manufacturing units after the use of widely acclaimed, and achieved good results.
Q:Are steel tubes and round steel in weight or length when purchased?
It's priced by weight. The cutting process should size to determine the length (otherwise - please specify the weight of the material), the material ration to calculate weight for cost accounting as.
Q:What is the difference between seamless steel pipe and welded pipe?
Such as hydraulic equipment pipeline connection. The weld seam of common steel pipe is its weak link, and the quality of weld is the main factor that affects its overall performance. People who have lived in the north have experienced the experience of freezing pipes and pipes in winter, and the places where they burst are usually welds. Welded pipe is not seamless steel pipe.
Q:Where is the difference between seamless steel pipe and welded pipe
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
