Product Description
The characteristics of galvanized steel pipes :
1. The zinc layer on the inner and outer surfaces is thick, with a bright and uniform color, and strong corrosion resistance;
2. Pipe wall thickness, strong mechanical properties, good compression and bending resistance;
3. Small caliber optional threaded thread and sleeve tight set type; Large diameter options include socket expansion and clamp connection.
Galvanized square pipe is a kind of hollow square sectional steel pipe with square section shape and size made of hot rolled or cold rolled galvanized strip steel or galvanized coil as billet by cold bending processing and then by high frequency welding, or the cold formed hollow steel pipe made in advance by hot dip galvanized square pipe processing.
There are two types of galvanized square tubes: hot-dip galvanized square tubes and electro-galvanized square tubes. There are wet method, dry method, lead-zinc method, redox method and so on for hot-dip galvanized square tube. The main difference between different hot-dip galvanizing methods is the method used to activate the surface of the pipe body to improve the quality of galvanizing after the steel pipe is pickled and cleaned. The current production mainly adopts dry method and redox method. The surface of the electro-galvanized zinc layer is very smooth and dense, and the structure is uniform: it has good mechanical properties and corrosion resistance: zinc consumption is 60% to 75% lower than that of hot-dip galvanizing. Electrogalvanizing is technically complex, but it must be used for single-sided coating, double-sided coating with different thicknesses on the inner and outer surfaces, and thin-walled tube galvanizing.
Hot-dip galvanized square pipe is a square pipe made of steel plate or steel strip after crimping and welding, which is formed by a series of chemical reactions in hot-dip galvanized pool. It can also be a hollow square cross-section steel pipe made by cold bending of hot-rolled or cold-rolled galvanized steel strip and then high frequency welding. The production process of the pipe is simple, the production efficiency is high, the variety specifications are many, and the equipment is less, but the strength is generally lower than that of the seamless square pipe.
The production process of galvanized pipes:
It can be divided into three basic methods: cold drawing, cold rolling, and hot rolling
Hot-dip galvanized square pipe has good strength, toughness, plasticity, welding and other process properties and has good ductility, its alloy layer is firmly attached to the steel base, so the hot-dip galvanized square pipe can be cold stamping, rolling, wire drawing, bending and other forms without damaging the coating; Suitable for general processing such as drilling, cutting, welding, cold bending and other processes. The surface of hot-dip galvanized parts is bright and beautiful, and can be directly used in engineering according to demand.

Galvanized square pipe is a special pipe with hollow cross section, and it is precisely because of this special design that the application of this pipe in our lives has been expanded a lot. Especially in our shipbuilding and construction industries, but also in the military, aviation field has also made great progress.
Hot-dip galvanized square tube: It is a square tube welded after the use of steel plate or steel strip crimping, and on the basis of this square tube, the square tube is placed in the hot-dip galvanized pool after a series of chemical reactions. The production process of hot-dip galvanized square pipe is relatively simple, and the production efficiency is very high, the varieties and specifications are also many, and the equipment and funds required for this kind of square pipe are very little, which is suitable for the production of small galvanized square pipe manufacturers. However, in terms of strength, the strength of this steel pipe is far lower than that of seamless square pipe.
Features of galvanized channel steel:
(1) It has a thicker dense layer of pure zinc covering the steel surface, which can prevent the steel substrate from contacting any corrosive solution and protect the steel substrate from corrosion. In the general atmosphere, a thin layer of dense zinc oxide layer is formed on the surface of the zinc layer, which is difficult to dissolve in water, so it plays a certain role in protecting the steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal.
(2) It has an iron-zinc alloy layer and is tightly bonded. Exhibits unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere:
(3) Due to the firm combination, zinc and iron are soluble in each other, and have strong wear resistance:
(4) Due to the good ductility of zinc, its alloy layer is firmly attached to the steel base, so hot-dip parts can be cold punched, rolled, drawn, bent, etc. without damaging the coating;
Product Usage
galvanized steel pipe/tule It is widely used in subway, tunnel and other underground structure, along the river, coastal areas, and high standard civil, commercial, and public buildings for the installation of exposed and concealed electrical lines, pipelines, and civil air defense projects.
Hot-dip galvanized square pipe because of its excellent performance is often used in: glass curtain wall, power tower, communication grid, water and gas transmission, wire bushing, housing, Bridges, metal structure, power transmission, etc., has been widely used in recent years.
Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quadruple junction crystal, which forms a barrier on the steel plate and thus effectively prevents the penetration of corrosion factors. Corrosion resistance The barrier layer from zinc provides strong protection. When zinc is sacrificed for protection in the cut edges, scratches and abrasion parts of the coating, zinc forms an insoluble oxide layer, which acts as a barrier protection.
