60.3*2.5mm Welded Galvanized Gi Iron Steel Pipe Price From China Factory
Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. Hot dip galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube base and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
Features
The advantages of galvanized pipe are light weight, corrosion resistance, high temperature resistance, no deformation and anti-static, the specific advantages are as follows:
1, light weight:
The parameters of the galvanized pipe are 1/5 of the square steel, so it has better weight and light performance, lighter than the square steel, and its weight is only 1/5 of the square steel.
2. Corrosion resistance and high temperature resistance:
Galvanized pipe parameters are 15CrMo pearlitic heat-resistant steel, so it has good corrosion resistance and high temperature resistance, better than square steel, galvanized pipe corrosion resistance to acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact resistance and fatigue resistance, do not need regular maintenance, effective service life of up to 15 years or more.
3, no deformation and anti-static:
The parameter of galvanized pipe is D133×4.5, so it has good antistatic performance, better than ordinary steel pipe, galvanized pipe is high elasticity, reused in mechanical equipment, no memory, no deformation, and antistatic, galvanized pipe has excellent mechanical properties, easy machining, etc.
Application
Galvanized pipe has high anti-corrosion properties, widely used in construction, industry, agriculture and other fields, such as stair handrails, outdoor water pipes, gas pipelines and so on.
First, the construction field
1. Stair handrail: The surface of the galvanized pipe is covered with a zinc layer, which can prevent rust and corrosion of the pipe, so it is very suitable for the material of indoor stair handrail.
2. Outdoor water pipes: For outdoor water pipes, corrosion resistance and high pressure resistance are required, and galvanized pipes can meet these characteristics and become a classic outdoor water pipe material.
3. Architectural decoration: In terms of architectural decoration, galvanized pipes can be used for indoor and outdoor corridors, balconies, decorative doors, etc., which are not only corrosion-resistant, but also look more beautiful on the surface.
2. Industrial field
1. Marine engineering: The Marine environment is often corroded by seawater, and the corrosion resistance of galvanized pipe is very good, so it is widely used in Marine engineering.
2. Gas pipelines: Galvanized pipes are also widely used in gas pipelines and gas pipelines, because the zinc layer covered by their surface can be oxidized. This makes galvanized pipes more resistant to corrosion and safer than other materials.
3. Agriculture
1. Agricultural channels: Galvanized pipes are also widely used in the agricultural field, such as underground irrigation channels, pumps, watering equipment, etc. Because they can carry water pressure for a long time, while preventing pipe rust and clogging.
2. Aquaculture: In the aquaculture industry, galvanized pipes are used to build the pipes and metal skeletons of poultry houses and livestock houses, which can not only avoid rust and breeding bacteria, but also carry a lot of weight.
In short, the characteristics of galvanized pipe in the application determine that it can be applied in many fields, with strong corrosion resistance, light weight, stable performance and many other advantages. With the further development of the market, the application field will continue to expand.

Details
Under normal circumstances, the zinc layer thickness of galvanized pipes is between 5um and 40um. Different use scenarios, purposes and production processes will affect the thickness of the zinc layer, so the specific zinc layer thickness needs to be determined according to the actual demand. When purchasing galvanized pipe, it is necessary to choose the appropriate zinc layer thickness according to the specific needs.
1. Packaging material: commonly used packaging materials are plastic film, woven bags, cartons, wood, pallets and so on. Under normal circumstances, we recommend the use of plastic film and woven bags for packaging, these two materials have excellent impact resistance and buffer performance, can better protect the hot-dip galvanized pipe.
2. Packaging tape and cable: Packaging tape and cable are essential auxiliary materials for hot-dip galvanized pipe packaging. It is recommended to use durable and durable packaging tape and cable to avoid damage to hot-dip galvanized pipe during transportation.
