What is a steel pipe used for?
Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling steel strips through processing. Generally, the steel strips are unpacked, flattened, curled, and welded to form round tubes, which are then rolled into square tubes and cut into required lengths.
Square tubes have a wide range of uses. They are used in many industries such as construction, machinery, shipbuilding, electricity, agriculture and animal husbandry, warehousing, fire protection, and home appliances. It can be said that they are an indispensable steel material for the development of modern industry. Square tubes are an indispensable part of the construction field. With the hot construction projects, the demand for square steel tubes is also increasing.
Galvanized Pipe
Galvanized pipes, also known as galvanized steel pipes, are divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thick galvanized layer, uniform coating, strong adhesion, and long service life. Electro-galvanizing has low cost, but the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
Galvanized steel pipes can be used in urban water supply pipes, industrial water pipes, and transportation of oil, natural gas, chemical liquids and other fields.
Hot-dip galvanized pipes
Hot-dip galvanized pipe: Hot-dip galvanized pipe is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.
Uses of hot-dip galvanized steel pipe: mainly used for transporting gas and heating.
ERW Steel Pipe
"ERW steel pipe" is Electric Resistance Welding pipe, abbreviated as ERW, which is used to transport gas and liquid objects such as oil and natural gas. It can meet various high and low pressure requirements and occupies an important position in the world's transportation pipe field.
LSAW Pipe Manufacturers
Straight seam submerged arc welded pipe products are suitable for various oil and natural gas pipelines and building steel structures, such as oil pipelines, natural gas, urban pipelines, mining water-coal slurry pipelines, high-voltage transmission lines, wind power generation, bridges, high-speed railways, etc.
SSAW is the abbreviation of Spirally Submerged Arc Welding, which means spiral seam submerged arc welded pipe. SSAW steel pipe is spiral welded steel pipe, also known as spiral steel pipe, spiral welded pipe or spiral pipe.
It uses double-sided submerged arc spiral welding technology to continuously weld narrow strip (plate) coils into steel pipes. It has been widely used in my country's long-distance oil and gas pipeline projects such as the West-East Gas Pipeline, and is the main pipe type used in my country's long-distance oil and gas pipeline projects.
Spiral steel pipes are widely used in natural gas, petroleum, chemical industry, electricity, heat, water supply and drainage, steam heating, pressure steel pipes for hydropower stations, thermal power generation, water sources and other long-distance transmission pipelines and piling, dredging, bridges, steel structures and other engineering fields.
Carbon Steel Seamless Steel Pipe
Seamless steel pipes for structures are mainly used to support the well wall during drilling and after completion to ensure the drilling process and the normal operation of the entire oil well after completion. The pumping pipe mainly transports oil and gas from the bottom of the oil well to the ground.
It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction.
