Q:Which is better, galvanized steel pipe or stainless steel?
In rural and urban areas, it is often necessary to wash them in order to keep them in the open. In the heavily polluted industrial and coastal areas, the surface can be very dirty and even rust. But to obtain the aesthetic effect of outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other building applications, but in corrosive industrial or marine atmospheres, it is better to use 316 stainless steel. There are several design criteria including 304 and 316 stainless steel.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
Q:Will the steel tube dance?
In a single pole dance performance, the dancer moves more naturally, herself, moves and techniques, and does what she wants to do, while the style of dance is determined by herself, no one intervenes, and quite free.
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: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 difference between seamless steel pipe and welded pipe?
The difference can be seen from the outward appearance that the welded pipe is welded by roll up.
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:What's the difference between round and round tubes?
Round steel is solid and round tubes are hollow
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
However, there are a variety of non GB steel tubes on the market, mainly in the wall thickness, and are thinner than the national standard requirements, you said that thickness may have, but the thinnest only about 2.6mm-2.7mm.
Q:What does "SC50" steel pipe mean in civil engineering?
The corrosion resistance of Ni is very strong in acidic environment. In the environment containing sulfuric acid or hydrochloric acid, the higher the content of Ni in the welded pipe is, the stronger corrosion resistance is. In general circumstances, the addition of Cr in a T-junction steel pipe prevents erosion. The marginal condition of the steel strip is another important cause of the wrong edges. The influence of mass flow rate, heat flux density and structural parameters (ratio of spiral curvature diameter and diameter of T-shape welded tube Dc/D) on heat transfer coefficient of saturated bubble boiling in vertical helical tubes.
