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 the production process of seamless steel tube?
Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspectionThe production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
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 external parts name
Fastener type steel pipe scaffold fastener malleable iron casting should be adopted, its basic form has three kinds: vertical cross bar for a connection between the rectangular fastener, fastener for rotating connecting parallel or oblique bars and rods for butt joint butt joint fastener.
Q:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Small and medium-sized cold drawn and hot-rolled are many, large caliber is hot rolling, cold rolled spot less.
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
Galvanized steel pipe is a kind of antirust steel pipe, often used in relatively high water supply pipeline or hot water pipeline, the price is higher, can use for at least 30 years;PPR pipe is a kind of polypropylene plastic, which is commonly used in environmental protection plastic pipes, but only suitable for low temperature occasions. It is mainly used for water supply;
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20G seamless steel tube is a high-pressure boiler tube. In addition to carbon content, 20G seamless steel tubes also have some trace elements that are more suitable for use as boiler pressure vessels. In addition, 20G also focuses on its physical performance. Such as bending, impact and tensile properties. 0G seamless steel tube is a kind of steel strip with hollow section and without seams. A steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
Full house scaffold is mainly used in the decoration construction of the single storey workshop, exhibition hall, gymnasium and so on. It consists of vertical pole, cross bar, diagonal brace and scissors support
Q:45 and 316 which steel tubes are of high hardness?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. 316F stainless steel is easy to cut stainless steel with high sulfur content. Good corrosion resistance, easy processing, good smoothness, suitable for axial parts.
