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.
1, The allowable deviation of galvanized square rectangular pipe wall thickness, when the wall thickness is not greater than 10mm shall not exceed the nominal wall thickness of plus or minus 10%, when the wall thickness is greater than 10mm, it is plus or minus 8% of the wall thickness, except for the wall thickness of the corner and weld area.
2. The usual delivery length of galvanized square tube is 4000mm-12000mm, with 6000mm and 12000mm being the majority. Square pipe allows the delivery of not less than 2000mm short size and non-fixed size products, can also be delivered in the form of interface pipe, but the buyer should cut the interface pipe when in use. The weight of short size and non-fixed size products shall not exceed 5% of the total delivery volume, and for square pipe with a theoretical weight greater than 20kg/m, it shall not exceed 10% of the total delivery volume.
3, the bend of galvanized square rectangular pipe shall not be greater than 2mm per meter, the total bend shall not be greater than 0.2% of the total length.
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.
Mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agriculture and chemical machinery, glass curtain wall, automobile chassis, airports and so on.
Because the galvanized square pipe is galvanized on the square pipe, the application range of galvanized square pipe has been greatly expanded compared with the square pipe. It is mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agriculture and chemical machinery, glass curtain wall, automobile chassis, airports and so on.
The production process of galvanized pipes:
It can be divided into three basic methods: cold drawing, cold rolling, and hot rolling
Storage capacity
Adequate supply of goods in the warehouse
1. The company has stable and good supply channels with sufficient supply sources
2. Complete goods, quality assurance, and delivery speed
3. Support wholesale and retail
Quality inspection
We have a strict quality system, the raw materials of each order will be tested before production, and a rolling mill test certificate will be provided to customers.
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. Galvanized square pipe from the production process is divided into hot galvanized square pipe and cold galvanized square pipe. It is precisely because of the different processing methods of these two galvanized square pipes that they have many different physical and chemical properties.
The cold galvanized square pipe is to use the principle of cold galvanized on the square pipe used to make the square pipe have anti-corrosion performance. Different from hot-dip galvanized coating, cold galvanized coating is mainly anti-corrosion through the electrochemical principle, so it is necessary to ensure that the zinc powder is in full contact with the steel, resulting in electrode potential difference, so the surface treatment of steel is very important.
Galvanized square pipe is a name for square pipe and rectangular pipe, that is, steel pipe with equal side length. It is made of strip steel by processing and rolling. Generally, the strip is unpacked, flat, crimped, welded to form a round tube, which is then rolled into a square tube and cut to the required length. They usually come in packs of 50. Also known as square and rectangular cold-formed hollow steel, referred to as square tube and rectangular tube, code F and J respectively.
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.
Galvanized square pipe has two categories: hot-dip galvanized square pipe and electric galvanized square pipe. Hot-dip galvanized square pipe has wet method, dry method, lead-zinc method, REDOX method and so on. The main difference between different hot dip galvanizing methods is what method is used to activate the surface of the pipe to improve the quality of galvanizing after the acid dip cleaning of the steel pipe. At present, dry method and REDOX method are mainly used in production, and their characteristics are shown in the table. The surface of the zinc layer of electrogalvanizing is very smooth and compact with uniform structure. Good mechanical properties and corrosion resistance;
