Q:25 of the steel pipe with 6 in charge of what is the difference?
Outer diameter representation of steel pipe:When the design is nominal diameter DN means diameter, should be nominal diameter DN and the corresponding product specifications table. Specification for unplasticized polyvinyl chloride pipes for building drainage, de (nominal outer diameter) * e (nominal wall thickness), (GB, 5836.1-92), polypropylene (PP) pipe for water supply, specifications by de * e (nominal outer diameter * wall thickness).
Q:The difference between carbon and welded steel tubes
Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
The pile reinforcement cage construction characteristics: in general application of the reinforcement cage can be used when not required manual assembling reinforcement cage, such as deep or large pile diameter should be used for solid and solid mechanism of reinforcement cage better (by reinforcing cage seam welder production) to meet Zhuang Jishi high technology requirements, enhance the stability of pile foundation.
Q:How do you solder purple copper plate and steel tube?
When the copper and copper tube size is too large, argon welder welding, DC argon arc welding machine, of course, when DC argon arc welding welding belongs to welding, argon arc welding of brass with Wei Odin 204S welding, the argon arc welding wire for gas welding is not brass wire, this concept must be clear, the wire diameter of 2 80-120A, welding current parameters, if the copper thickness is relatively thick, with a red copper welding after welding preheating in advance.
Q:Seamless steel pipe and welded pipe what is the difference?
The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Seamless steel pipe material is steel, but also seamless, high strength, used in high pressure, harsh environment occasions. The galvanized pipe is only made on the steel tube, which is similar to the so-called antirust paint
Q:How to descaling galvanized steel pipe?
Galvanized steel tubes will not rust in principle.... Batch rust with weak acid water immersion, individual can use steel wire brush brush on it.
Q:Where is the difference between seamless steel pipe and welded pipe?
In appearance, seamless steel pipe and welded steel pipe difference in the welded pipe wall welded tendons, and seamless No.
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless 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. Compared with solid steel such as round steel, steel tube is lighter in strength and equal in resistance to bending and torsion. It is an economical cross section steel and is widely used in the manufacture of structural and mechanical parts.
Q:What are low-pressure carbon steel tubes?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;(2) by refining methods can be divided into open hearth steel, converter steel;(3) according to deoxidization methods, they can be divided into boiling steel (F), killed steel (Z), semi killed steel (b) and special killed steel (TZ);(4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%);(5) according to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur, higher), high quality carbon steel (low phosphorus and sulfur) and high quality steel (lower phosphorus and sulfur) and super quality steel.Description: the carbon content in general carbon steel is higher, the hardness is higher, the strength is higher, but the plasticity is lower.
