Hot Dip Galvanized Rectangular Tube, also known as flat pipe, flat square pipe or square flat pipe, is a hollow strip of steel.

Hot Dip Galvanized Rectangular 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.

Hot Dip Galvanized Rectangular Tube, Distinguish Between

Sizheng has hot-dip galvanized rectangular tube and electric galvanized rectangular tube two categories. Hot dip galvanized square pipe wet, dry, lead – zinc, REDOX, etc. The main difference between different hot-dip galvanizing methods is how to activate the surface of steel pipe 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

Galvanized 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 Dip Galvanized Rectangular Tube Production Process

Hot Dip Galvanized Rectangular Tube Many people are more understanding, but not all people know the production process of galvanized rectangular tube, now the company will show you the production process of galvanized rectangular tube is what

Hot Dip Galvanized Rectangular Tube Production process: due to the lack of heating in the production process, there is no pitting and oxide sheet defects that often occur in hot rolled rectangular tube, with good surface quality and high finish. And the size precision of cold rolled products is high and the size precision of cold rolled products is high, the product performance and organization can meet some special use requirements, and the organization can meet some special use requirements, such as electromagnetic performance, deep drawing performance and so on. Electromagnetic performance, deep drawing performance, etc. Tool steel has good wear resistance, that is, the ability to resist wear. Good abrasion resistance, i.e. the ability to resist wear and tear. Tools can retain their shape and size under conditions of considerable pressure and friction and still maintain their shape and size. Galvanized square tube is divided into hot-dip galvanized and electric galvanized. Hot-dip galvanized square tube has thick galvanized layer, uniform coating, strong adhesion, long service life and other advantages. The cost of electrogalvanizing is low, the surface is not very smooth, and its corrosion resistance is much different than that of hot-dip galvanizing square tube.

Hot Dip Galvanized Rectangular 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 Dip Galvanized Rectangular Tube Acceptance Criteria

Hot Dip Galvanized Rectangular 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 deviation of the product has a specified range, that is, the size of the “allowable deviation.
