OEM/ODM China Circular Hollow Section - Hot Galvanized Steel Rectangular Steel Tube – Zheyi Detail:

hot Galvanized Steel Rectangular Steel Tube It is a hollow strip of steel, also known as flat pipe, flat square pipe or square flat pipe (as the name implies). A large number of pipeline used for conveying fluid, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at the same time, lighter weight, so also widely used in manufacturing machinery parts and engineering structures. Also commonly used for the production of conventional weapons, gun barrels, shells and so on.

Distinguish Between

Hot Galvanized Steel Rectangular Steel Tube And electric galvanized moment tube two categories. hot Galvanized Steel Rectangular Steel Tube There are wet method, dry method, lead-zinc method, REDOX method and so on.

Different hot Galvanized Steel Rectangular Steel Tube The main difference of the method is how to activate the surface of the tube body to improve galvanizing quality after acid leaching cleaning. At present, dry method and REDOX method are mainly used in production, and their characteristics are shown in the table. The surface of zinc layer is very smooth and compact, and the structure is uniform. Good mechanical properties and corrosion resistance; Zinc consumption is 60% ~ 75% lower than hot dip galvanizing. Electrogalvanizing has certain complexity in technology, but it is necessary to use this method for single-sided coating, double-sided coating with different thickness of inner and outer surface coating, and galvanized thin-walled pipe.

Introduce The Galvanized

Hot Galvanized Steel Rectangular Steel Tube Its protective effect is stronger, strong corrosion resistance. The entire structure is made of zinc, forming dense tetrad crystals that form a barrier on the steel plate, thus effectively preventing corrosion agents from penetrating. Corrosion resistance from zinc barrier layer protection. When zinc sacrificial protection on cut edges, scratches and coating abrades, zinc forms an insoluble oxide layer and acts as a barrier protection.

Hot Galvanized Steel Rectangular Steel Tube Said method
Example: rectangular tube 40*60*5*6m, expressed as: 40 (height)* 60(width)*5 (wall thickness)* 6m (number of meters). Because the moment tube commonly used meters of 6 meters; The general industry is simply expressed as: 40*60*5

Hot Galvanized Steel Rectangular Steel Tube Acceptance criteria
hot Galvanized Steel Rectangular Steel Tube Generally, the appearance of the product is judged to be qualified. If there is leakage plating, pitting, white spots, heavy skin, bubbles, green and high frequency on the surface of the outer wall of the square tube, it is judged as unqualified product. But in the product standard, the deviation of the product has a specified range, that is, the “allowable deviation” of the size.
