Q:How big is the seamless steel tube of DN50?
DN refers to the nominal diameter, the outer diameter is 60.3mm
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: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:What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?
DN represents the path of the tube". Fair represents diameter. Path is the diameter of the fluid through which it should be inside. The diameter may be the outer diameter or the inner diameter. The diameter is only used when the pipe is used for flow through. Fair as long as the garden can be used. According to the requirements of mechanical drawing fair, DN text notes.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe is suitable for medium voltage and low voltage 0.4MPa below the pressure pipe wall thickness. According to the different pressure is not the same, so the steel tube can be used for high pressure.
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 steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Where outdoor heating pipes are buried, what steel pipe shall be referenced by the 11.1.2 code for installation of outdoor piping?:This chapter applies to the quality inspection and acceptance of the outdoor heating pipe network installation of the plant and the civil building group (residential area) with the saturation steam pressure not greater than 0.7MPa, and the hot water temperature not exceeding 130 degrees celsius.
Q:How to establish a concrete-filled steel tubular column model in ANSYS?
A two unit model or a composite unit model can be adoptedTwo units are constructed of steel tubes and concreteA composite unit may be either a fiber element or a section conversion attribute
Q:What is the difference between steel pipe and round steel?
Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
