Hot Dipped ASTM Standard ERW 200*200 Hollow Section Square Tubing Galvanized Steel Pipe
Galvanized square tube widely used in construction, machinery, coal, chemical, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery manufacturing industry. Galvanized square tube surface is hot-dip plated or galvanized layer welded steel pipe. Hot-dip galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized square tube is widely used, in addition to water, gas, oil and other general low-pressure fluid pipeline, but also for the oil industry, especially offshore oil wells, pipeline, Pipe with the tube, as well as the bridge bridge pile, mine tunnel support frame with the tube.The galvanized square tube is an alloy layer produced by the reaction of the molten metal with the iron matrix, so that both the substrate and the plating layer are combined. Hot-dip galvanizing is the first pickling of the steel pipe, in order to remove the iron oxide surface of the steel pipe, pickled, through ammonium chloride or zinc chloride water solution or ammonium chloride and zinc chloride mixed aqueous solution And then into the hot-dip plating tank. Galvanized pipe and molten bath complex physical and chemical reactions, the formation of corrosion-resistant structure of a dense zinc alloy layer. Alloy layer and pure zinc layer, steel pipe body integration. So its strong corrosion resistance.

 Feature

Galvanized square steel tubes have excellent comprehensive mechanical properties, stable performance and excellent quality. The main reason for the wide application of galvanized rectangular pipe is that it can

play more advantages in the use process and meet the needs of more industries. It can show better corrosion resistance when the service quality is very stable, so don't worry about the quality risk.

 Classification

Square tubes are classified according to their cross sections:

(1) simple square tubes-_square tubes and rectangular frame square tubes;

(2) complicated square tubes-_flower-shaped square tubes, open-mouthed square tubes, corrugated square tubes and special-shaped square tubes. Classification of metal surface treatment of galvanized square

tubes: according to metal surface treatment, square tubes are divided into hot-dip galvanized square tubes, phosphatized square tubes, oiled square tubes and pickling passivated square tubes

Classification of main uses of galvanized square tubes: Square tubes are classified according to their main uses-square tubes for decoration and design, mechanical equipment, industrial grade square tubes

for mechanical equipment, square tubes for chemical plants, steel frame structures, square tubes for shipbuilding industry, square tubes for trolleys and square tubes for steel columns and beams.

Classification of wall thickness of galvanized rectangular tubes: rectangular tubes are classified according to wall thickness-ultra-thin-walled rectangular tubes, thin-walled rectangular tubes and thick-walled

rectangular tubes.

 Application

Galvanized square steel pipes are mainly used in curtain wall, architecture, machinery manufacturing, steel construction projects, shipbuilding, solar power generation support, steel structure engineering, power

plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, etc
