Product Of Advantages

Black Carbon Steel Pipe is a metal pipe composed of carbon and iron elements. It has the following characteristics:
High strength and hardness. Carbon steel pipes can withstand greater pressure and weight, which gives them good performance in bearing structures and transporting liquids and gases.
Good toughness. Carbon steel pipes have good toughness and wear resistance and are suitable for transporting hot and cold liquids and abrasive substances.
Strong corrosion resistance. Carbon steel pipes can be used in various corrosive environments, but their corrosion resistance is relatively weak and they are easily corroded by the external environment. Especially when used in humid corrosive media, they are prone to corrosion and rust.
Good processability. Carbon steel pipes are easy to process and customize, can be processed and connected through welding, threaded connections, etc., and have good plasticity.
Good economy. The cost of carbon steel pipes is low and the price is relatively economical.
Carbon steel pipes are widely used in petroleum, natural gas, chemical industry, aerospace, aviation, machinery manufacturing and other fields. They are also used in construction, shipbuilding, bridges and other fields, especially playing an important role in transporting liquids and gases.

Product Description

Main Application:

1. Low Carbon Steel Pipe are used for the transportation of general lower pressure fluids such as water, gas, air, oil and heating steam.

2. Ordinary carbon steel wire casing (GB3640-88) is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings, and installation of machinery and equipment.

3. Straight seam electric welded pipe (YB242-63) is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on.

4. The spiral seam submerged arc welded pipe for pressurized fluid transportation (SY5036-83) is made of hot-rolled steel strip coils, spirally formed at constant temperature, and welded by double-sided submerged arc welding. Seam steel pipe. The steel pipe has strong pressure bearing capacity, good welding performance, large steel pipe diameter, high transmission efficiency, and can save investment in laying pipelines. It is mainly used for pipelines transporting oil and natural gas.

5. Spiral seam high-frequency Q235 Steel Pipe for pressure fluid transportation (SY5038-83) is made of hot-rolled steel strip coils, spirally formed at constant temperature, welded by high-frequency lap welding, and used for pressure fluid transportation Spiral seam high frequency welded steel pipe. The diameter of the steel pipe is large, the transmission efficiency is high, and the investment in laying pipelines can be saved. It is mainly used for laying pipelines for transporting oil and natural gas.

6. The spiral seam submerged arc welded steel pipe (SY5037-83) for general low-pressure fluid transportation is made of hot-rolled steel strip coils, spirally formed at constant temperature, and made by double-sided automatic submerged arc welding or single-sided welding. Submerged arc welded steel pipes for general low-pressure fluid transportation such as water, gas, air and steam

Process of production
First of all, raw material uncoiling: The billet used for it is generally steel plate or It is made of strip steel, then the coil is flattened, the flat end is cut and welded-looper-forming-welding-inner and outer weld bead removal-pre-correction-induction heat treatment-sizing and straightening-eddy current testing-cutting- Water pressure inspection—pickling—final quality inspection and size test, packaging—and then out of the warehouse.

Packing and Transportation

Packaging is generally naked, steel wire binding, very strong.
If you have special requirements, you can use rust proof packaging, and more beautiful.

1. Cargo packaging
Carbon steel is a metal material that is prone to rust and needs to be packaged and protected during transportation. Generally, wooden boxes, cartons or plastic films are used for packaging to prevent carbon steel products from direct contact with the atmosphere and moisture, which may cause rust and oxidation. At the same time, the packaging of goods should comply with transportation specifications and standards to ensure that the goods are not damaged during transportation.
2. Transportation environment
The transportation environment is the key to whether carbon steel can reach its destination safely. The first thing you need to pay attention to is temperature and humidity to avoid extreme high, low and high humidity conditions during transportation, which may cause the goods to get damp or freeze to crack. Secondly, attention should be paid to the isolation between goods and other goods to avoid collisions, friction, etc. during transportation, resulting in damage to the goods.
3. Loading and unloading operations
Loading and unloading operations are the most problematic aspects of carbon steel transportation. During loading and unloading operations, special hoists, forklifts and other machinery are required to prevent excessive squeezing, pulling, beating and other operations. In addition, safety protection measures need to be taken before operation to avoid safety risks to personnel and the environment caused by improper operation.
To sum up, carbon steel transportation must not only pay attention to cargo packaging and transportation environment, but also pay attention to loading and unloading operations, so as to ensure that carbon steel single-axle vehicles, carbon steel bicycles and other goods can be transported safely and stably to their destinations.
