Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Steel tube Kg/m (including seamless steel tubes and welded tubes) theoretical formula per meter weight: W=0.02466 * S * (D-S)Of which: S - wall thickness (mm), D - steel tube diameter (mm), W - kg / M
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
Electrical, gas, water, power, fluid, pipe.The main production process for hot rolling seamless steel tube (the main inspection):Tube preparation and check delta to billet heating, heating, rolling, perforated pipe, steel pipe and heat treatment, diameter (minus) Delta to finished tube straightening, finishing and inspection of delta (nondestructive, physicochemical, Taiwan inspection and warehousing)Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspection
Q:How can galvanized steel tubes be painted on the surface?
Galvanized parts are nonferrous metals, ferrous metals are black, all metal adhesion is poor;
Q:Why can't stainless steel be put together with carbon steel tube?
1, the potential difference is: potential "stainless steel tube" and the negative potential "carbon steel" coupled "stainless steel", "a cathode carbon steel tube" is anode potentials of the two difference the greater the galvanic corrosion is bigger.2. An electronic passage formed by wire connection or direct contact. The carbon in the carbon steel tube loses its electrons to the stainless steel tube and the surface is absorbed by the etchant.3. Electrolyte: the contact area of two metals is covered or submerged by electrolyte. The iron in the carbon tube loses electrons to form ions into the solution, and the electrons on the surface of the stainless steel tubes are taken away by the corrosive agents in the electrolyte (such as oxygen in the air). Electrolytes become ionic channels.
Q:Material of welded steel pipe
GB/T3092-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is: Q235 grade a steel.GB/T14291-1992 (mine fluid conveying welded steel pipe). It is mainly used in mine pressure air, drainage and vertical seam gas welding pipe. Its representative material is Q235A, B grade steel.
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.
Q:What is the difference between seamless steel pipe and welded pipe?
The main molding process is different. Ordinary steel pipes, such as tap water pipes, are usually welded by bending flat plates, and you can find a seam on it;
Q:Why seamless steel pipe called seamless steel pipe?
Seamless steel pipe is a hollow section, without the joint round, square, rectangular steel. Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel pipe with a hollow section, as pipe conveying fluid, compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, bike frame and construction using steel scaffolding.
Q:Where is the difference between seamless steel pipe and welded pipe?
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe, not seamless steel pipe, seamless steel pipe, welded seam, how can it be called seamless pipe?. Tell you a method: measurement of wall thickness, multi test several points, if each point, that is because it is cold drawn pipe, seamless pipe, hot rolling, wall thickness may% by sample.
