Q:How can galvanized steel pipe be connected with stainless steel pipe?
The method of non direct fusion is adopted, such as blue, silk head and movable joint
Q:Can the KBG25 steel tube hold 4 six types of cables?
The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
12Cr1MoVG is a kind of material for alloy tubes. The main purpose is to make the steel structure in the boiler, the use temperature of 580 degrees, requiring high temperature resistance steel plate, durable strength, steel plate in the normalized and tempered state delivery. 12Cr1MoV alloy tube is based on high quality carbon structural steel. It is appropriate to add one or more alloy elements to improve the mechanical properties, toughness and hardenability of steel.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
In general, steel is divided into two groups according to their chemical composition: carbon steel and alloy steel;(1): carbon steel low carbon steel (C = 0.25%); carbon steel (0.25% < C < 0.60%); high carbon steel (C = 0.60%)(2): alloy steel, low alloy steel (alloy is less than or equal to 5%); in steel (5% < < 10% alloy; high alloy steel (alloy) = 10%)Carbon seamless steel tubes are mostly pipes for mechanical engineering structures and pipes for conveying fluids.
Q:What's the actual size of the DN25?
Different materials of steel pipe, nominal diameter of the same, then its outer diameter is the same, diameter = outside diameter -2 times, wall thickness.
Q:Difference between cold rolled steel pipe and common steel pipe
3, the caliber of cold-rolled steel tube is smaller than that of hot rolled steel tube4, from the price point of view, cold-rolled steel pipe is 1000-2000 tons more expensive than hot-rolled steel pipe
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'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:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
Including galvanized steel pipe, but galvanized steel pipe is generally used for plumbing professional, electrical professional generally only civil air defense or high anti-corrosion requirements of the region;
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
