Q:How can galvanized steel pipe be connected with stainless steel pipe?
Attention should be paid to the zinc coating at the side of the groove before welding. It is OK to brush silver powder after welding. There is a lot of information about the welding of carbon steel and stainless steel. Just check it online.
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:How long are the seamless tubes? Are they six meters long?
The usual length of steel pipe is as follows: hot rolled steel pipe 3000~12000mm and cold drawn steel pipe 3000~10500mm.
Q:Seamless steel tube with the tube with what is the difference?
Of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good, pay attention to oh!!
Q:Seamless steel pipe and welded pipe what is the difference?
Seamless steel pipe is made of solid round tubes and perforated without gaps. The welded pipe is made of steel or strip after welding and has a slit. Generally seamless pipe can be greater pressure on the city.
Q:SC15 what does galvanized steel pipe look like?
Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Dimensions of ordinary steel tubes (taken from GB/T 17395-1998)The theory of weight / (kg/m) | wall thickness (2.9 3.0mm: 3.33)
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Formula for calculating weight of welded steel pipe:Kg/m= (outside diameter mm-, wall thickness mm) * wall thickness mm*0.02466= (108-4) *4*0.02466=10.26 kg / MBecause of galvanizing, the weight is heavier than that of ordinary welded pipe 3%~6%.Therefore, the length of 6 meters galvanized steel pipe weighs about 10.26*6*1.06=65 kilograms
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 material of Q325 steel pipe?
In terms of deoxidation methods, F, B, Z can be expressed as boiling steel, flat killed steel, killed steel and boiling steel. They are deoxidized steel, which is of poor plasticity and toughness. Welded joints made of this material are susceptible to cracks when subjected to dynamic loads. Should not work at low temperatures, sometimes hardening. In contrast, calming steel is excellent and uniform, with good plasticity and toughness.
