Carbon steel tubes are made of ingot or solid round steel through perforation to make capillary tubes, and then made by hot rolling, cold rolling or cold drawing processes. This kind of pipe occupies an important position in the steel pipe industry in our country. 

Manufacturing process

Perforation process: The ingot or solid round steel is heated, and the perforator is pierced into a capillary tube, which is the first step in the production of carbon steel tubes.

Hot and cold rolling: The tube is hot rolled or cold rolled to achieve the desired wall thickness and outside diameter. Hot rolling is typically used for thicker tubes, while cold rolling is suitable for thinner, more precise applications.

Cold drawing process: In order to obtain higher dimensional accuracy and surface finish, some carbon steel pipes will also go through the cold drawing process.

Classification type

According to the classification of welding performance: carbon steel pipe can be divided into welded steel pipe and seamless carbon steel pipe. The welded steel pipe is rolled into a tube through the welding process, and the seamless carbon steel pipe is made through the above perforation, hot rolling and other processes, and there is no weld.

According to the classification of carbon content: according to the different carbon content, carbon steel pipes can be divided into low carbon steel pipes, medium carbon steel pipes and high carbon steel pipes, different carbon content of steel pipes in hardness, strength and toughness are different.

Application field

Construction industry: carbon steel pipes are widely used in building structures, scaffolding, etc., providing good support and connection.

Industrial production: In the petroleum, chemical, electric power and other industries, carbon steel pipes are used to transport fluids and gases, and are an important part of industrial pipeline systems.

Transportation: Carbon steel pipes are also used as structural components in automobiles, ships and railway vehicles, improving the safety and durability of vehicles.

Price quotation

Market price: The price of carbon steel pipe is affected by many factors such as raw material cost, market supply and demand, and international trade policy. Wholesale prices provided by e-commerce platforms such as Alibaba can provide a reference for buyers.

Specifications: There are differences in the price of carbon steel pipes of different specifications, such as DN300, DN400 and other pipes of different diameters.

Quality standard

National standards: The production and use of carbon steel pipes must meet the relevant national standards, such as GB/T3091-2015 "Welded steel pipe for low-pressure fluid transportation" and so on.

Quality control: Manufacturers need to carry out strict quality control in the production process, including chemical composition testing, mechanical performance testing, dimensional accuracy measurement, etc., to ensure that the quality of carbon steel pipes meet the requirements of use.

Future development trend

Technological innovation: With the advancement of manufacturing technology, the production of carbon steel pipes will be more automated and intelligent, improving production efficiency and product quality.

Green production: The improvement of environmental protection requirements will prompt carbon steel pipe manufacturers to adopt more environmentally friendly production processes to reduce energy consumption and emissions.

Carbon steel pipe, as a basic industrial material, plays an important role in many fields. Its production and application need to follow strict standards and specifications to ensure safety and performance. In the future, with the development of technology and changes in market demand, the production and application of carbon steel pipes will continue to optimize and innovate.
