WallosHow much is a ton of galvanized rectangular pipeEconomical production process

there will be thinning, so manufacturers usually use thick spot pipes. If thin raw materials are used, the products produced must be unqualified. Generally, there are about wires thinned. If the technology is not good or the drawn pipe is used, the thickness is significantly lower than the standard.Fake and shoddy square tubes are easy to scratch, because the equipment of fake and shoddy material manufacturers is simple and easy to produce burrs and scratch the surface of square tubes. Deep scratches reduce the strength of square tubes.Wallos,In the test place the sample between two parallel plates and press it evenly to the flattening distance h specified in relevant technical conditions with a press or testing machine at a speed of no more than mmin.Zinc layer thickness: there is a great difference between cold galvanized square pipe and hot galvanized square pipe in galvanizing process; Cold galvanized square pipes are prone to & ldquo; Electric burning & rdquo; The color of this part is gray and the zinc layer is thick. It is easy to form a current dead angle at the corner, resulting in an under current area. The zinc layer at this part is thin, and there is no zinc layer attached to the cold galvanized square pipe. The cold galvanized square pipe has no zinc lump and caking as a whole but the overall zinc layer is thin, and the thickness of the outer wall zinc layer is μ m-μ m. The and outer walls of the hot-dip galvanized square tube are attached with zinc layer, and there will be water marks and a few zinc tumors, but the overall zinc layer is thick, and the thickness of the zinc layer on the inner and outer walls of the square tube is -mu; M above. The nature of QB square tube!Rivas,Square tubes are classified by forming: forged steel; Cast steel; Hot rolled steel; Cold drawn steel.Square pipe is the name of square pipe that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment.Square tube is an essential material for the construction and Realization of industrialization. It is widely used and has a wide variety. According to different section shapes, square tube is generally divided into sections, plates,Wallos48 galvanized square pipe, pipes and metal products. In order to facilitate the production, ordering and supply of square tube and do a good job in operation and management, it is also divided into heavy rail, light rail, large section steel, medium section steel, small section steel and square tube cold bending Section steel, wire rod, medium and thick steel plate, sheet steel, electrical silicon steel sheet, strip steel, seamless steel pipe, square pipe, welded steel pipe, metal products, etc.

Structural stainless steel square pipe (gbt-) is a hot-rolled (extruded, light textile food, machinery and other industries.Spray fluorocarbon paint after.Square tube is made of different materials. It needs qualified inspection by relevant staff before leaving the factory. Square tube has a wide range of uses. Its main field is not only the construction industry, but also can be seen everywhere in our daily life. The service life of square tubes is mainly affected by surface treatment. I will explain the specific operations of surface treatment of square tubes.details,Classification of square tube steel is iron carbon alloy with carbon content of square tube between .% - %. In order to ensure its toughness and plasticity, the carbon content generally does not exceed %. In addition to iron and carbon, the main elements of steel also include silicon, manganese, sulfur, phosphorus, etc. There are various classifications of steel and square tubes, mainly including the following: square tubes are classified into ordinary steel according to quality (P & le; .%, S & le; .%)If the re inspection results are unqualified (including the items whose preliminary inspection results are unqualified and re inspection is not allowed), the supplier can submit them for acceptance one by one; Or re conduct heat treatment (the number of RE heat treatment shall not exceed times), and propose acceptance with a new batch.Steel used & mdash& mdash; Such as bridge steel, ship steel,WallosPrice of galvanized square pipe, boiler steel, pressure vessel steel, agricultural machinery steel, etc.

Steel for construction and engineering according to the classification of use without phase transformation or partial phase transformation of square tube: A. ordinary carbon structural steel; b. Low alloy structural steel; c. Steel reinforcement.Project scope,It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.Production standard classification square tube is divided according to production standard: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube and non-standard square tube.Large diameter qb square tube production standard classification square tube is divided according to production standard: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube and non-standard square tube.Wallos,There are many processing technologies for square tubes. I won't introduce the specific processing technology here. We only know about the processing technology of each other's tubes. We may have insufficient understanding of its heating technology. Next, I'll give you a detailed introduction to the heating technology of the lower tubes.In recent years, large-diameter seamless square tube plays a good role in economic development. Because there are many types of large-diameter seamless square tubes, the continuous casting process of large-diameter seamless square tubes is also different. What are the specific steps of the continuous casting process of large-diameter seamless square tube? As the name suggests, square tube is a kind of square tube type. Many materials can form square tube body. Its medium is used for what purpose and where it is used. Most square tubes are steel tubes,WallosSpecification of galvanized pipe, which are unpacked, leveled, crimped and welded to form round tubes, Then the round pipe is rolled into a square pipe and then cut into the required length. Generally, square tubes per package are mostly in large specifications in terms of spot, and . - ~~ - square tubes are divided into structural square tubes, decorative square tubes, building square tubes, mechanical square tubes, etc. according to their uses.Special performance steel: A. stainless and acid resistant steel; b. Heat resistant steel: including oxidation resistant steel, heat strength steel and air valve steel; c. Electric heating alloy steel; d. Wear resistant steel; e. Low temperature steel; f. Electrical steel.
