Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Hot rolling is relative to cold rolling, cold rolling is performed under recrystallization temperature, while hot rolling is rolling above recrystallization temperature.
Q:What's the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Outside diameter 89, most are cold drawn, more than 89 hot rolling.
Q:How to make the internal tooth of the steel pipe?
Compared with the ordinary light pipe, tube can effectively prevent the formation of steam film between the seal and the pipe wall, increase the light disturbance flow inside the tube, the tube wall temperature is more uniform, which can avoid the light pipe damage, and improve the heat transfer efficiency of boiler. The number of thread head of internal thread pipe is 4, 6 head and 8 head according to need. The main materials are 20G, SA210C, T2, T12, 12Cr1MoVG, 15CrMoG, T22, T23 and so on. China needs 2.5~3.0 tons per year of inner thread tube.
Q:What's the material of Q325 steel pipe?
Plain carbon structural steelIt's a kind of steel material. Q stands for the yield of this material, and the latter 325 means the yield value of this material, at around 325. And the yield value will decrease as the thickness of the material increases.
Q:The plastic pipe and steel pipe difference
In fact, including the steel plastic pipe plastic pipe, but on the market all the steel plastic pipe and plastic lining steel pipe is synonymous, lined with plastic pipe is made of galvanized steel pipe internal set of plastic pipe manufacturing process, process using high pressure steam to both adhesion.
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:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
