G550 Galvanized pipe belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.
DX51D Galvanized steel pipe has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion.
Characteristics of galvanized seamless pipe
Light weight, easy to handle
Because the galvanized seamless pipe itself is relatively light, the daily transportation and construction are very simple, which can save a lot of time and cost.
Good corrosion resistance
The corrosion resistance of seamless steel pipes is very good. They are resistant to acid, alkali, salt and atmospheric environment. Moreover, it is resistant to high temperature and impact, and does not need regular maintenance.
Good physical and chemical properties
Galvanized seamless pipe has very good physical and chemical properties, its tensile strength is more than 8 times stronger than ordinary steel, and its elastic modulus is also better than ordinary steel. Moreover, it also has good mechanical capabilities and is very easy for daily processing. Long term use will not deform, anti-static ability is good.
Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life.
1. For pipelines. Water, gas pipes, steam pipes, and oil and gas trunk lines. 2. Tubes for thermal equipment. Superheating pipes, high temperature and high-pressure boiler pipes for locomotive boilers. 3. For the machinery industry. Aviation structural tubes, automobile axle tubes, tractor structural tubes, etc.
The characteristics of galvanized I steel: 1. Strong corrosion resistance: the thickness of hot-dip galvanized layer can reach more than 300 m; 2. Good plasticity and toughness: no deformation in cold bending; 3. High strength: it can be used as the load-bearing framework of ceiling enclosure plate. 4. Good fire resistance: high melting point (1000 ° C), strong fire resistance; 5. Long service life: ≥ 100 years. 6. Flexible and fast installation: short construction period. 7. The color is bright and durable, without surface decoration
I-beam, also known as steel beam (English name universal Beam), is a long steel with the section of the I-shaped. I-section steel is divided into hot rolIed I-beam and lightweight I-beam
Stainless steel I-beam is a long steel bar with a grooved section. It can be used to form various stress components according to the different needs of the structure, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
Stainless steel I-beam is a carbon structural steel used for construction. It is a simple section steel, mainly used for metal components and plant frames. Good weldability, plastic deformation performance and mechanical strength are required in use. The raw steel billet of stainless steel I-beam is low carbon square steel billet, and the finished stainless steel I-beam is delivered in hot rolling forming, normalizing or hot rolling state.
H-beam is a kind of Economic section steel, which sectional area distribution is more optimized, the ratio of strength to weight is more reasonable, Mechanical properties of section is more better.It is developed from the I-section steel optimization of a better section mechanical properties of the economic section steel, because its section is same as the English letter "H" ,so be named as H-Beam. Because the various part of H-beam is arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, so it has been widely used.
Stainless H beam is widely used in beams and columns of industrial and civil steel structures. Steel structure load-bearing supports for industrial structures. Ship and machinery manufacturing frame structure. Steel piles and supporting structures of underground works.
With the rise of new economic building materials, galvanized H-shaped steel is widely used, especially in steel structure buildings, supports, and bridges. In short, it is integrated with many aspects of daily life.
Galvanized channel steel is an effective way of metal corrosion prevention, which is mainly used on metal structures and facilities in various industries.
