Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:How long are the seamless tubes? Are they six meters long?
6 meters of a root in general need to be customized, seamless tubes are mostly seven meters above the variable foot
Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
To look at the use of concrete after welding, if the stress is relatively large and thin galvanized pipe wall is recommended to not use welding, if the requirement is not high Po mouth welding should be welding depends on galvanized pipe material selection electrode generally no sealing material are 20
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Galvanized steel pipe wall thickness weight outer diameter 108mm 4mm 6 meters in length is about 10.26*6*1.06=65 kg.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%.
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 is the diameter of the steel tube DN20?
Usually the nominal diameter is nominal for cast iron pipe, steel pipe joints, concrete pipe pipe, seamless steel pipe does not use this notation (with diameter * wall thickness). With nominal diameter pipeline accessories, meaning with tube.
Q:What are low-pressure carbon steel tubes?
It's pressure levelThe design pressure (P) of pressure vessel is divided into four pressure levels: low voltage, medium pressure, high pressure and extra high pressure:(1) low voltage: Code L, 0.1MPa is less than or equal to p<1.6MPa(2) MP: Code M, 1.6MPa is less than or equal to p<10.0MPa(3) high voltage: Code H, 10.0MPa is less than or equal to p<100.0MPa(4) high voltage: Code U, P = 100.0MPa
Q:What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Seamless steel tube branch and seamed two, seamed steel pipe welding is formed, all two can be welded together, if you do not allow the use of seam tube cannot connect.
Q:How seamless steel tube is formed?
Seamless steel tubes are formed by cold drawing and hot rolling.
