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:Will the steel tube dance?
The steel tube dance tube has a rotating steel tube and a fixed steel tube, so that different types of steel pipe can be chosen according to the type of pipe dance performed by the dancer.
Q:DN80 seamless steel tube, what is the standard thickness?
Commonly used DN80 seamless steel pipe caliber should be 89mm*4mm.
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:How to distinguish between steel pipe and spiral pipe material?
Steel 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.
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:What is the process of spiral steel tube production?
1. open panel inspection: after the steel plate is opened, the product line is entered, and the ultrasonic examination of the whole plate is carried out first.2., flat milling: through the anvil machine to make the original coiled steel flat, and then through the milling machine on the edge of the steel plate two sides milling, so as to achieve the required plate width, plate edge parallelism and groove shape.
Q:RC is it welded steel pipe or galvanized steel pipe?
RC pipe is galvanized steel pipe, usually followed by the diameter, such as RC50, that is, 50mm galvanized steel pipe.
Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
Cracking carbon steel pipe higher requirements, the general carbon steel pipe to be normalized, the fluid carbon steel pipe as long as the normal annealing treatment.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
