Detail Information

Carbon steel seamless pipe(OEM ODM OBM)

Carbon steel seamless pipe overview

Carbon steel, also known as carbon steel, is an iron-carbon alloy with an internal carbon content of nearly 2%.In carbon steel materials, in addition to carbon, there are also various other components, such as manganese, sulfur, or silicon. Generally speaking, if the carbon content in carbon steel is relatively high, its hardness will increase and the strength generated will also be higher. Just note that the higher the carbon content, the lower the plasticity.

Seamless steel pipe is a steel pipe that is perforated from the entire round steel and has no welds on the surface, which is called seamless steel pipe. The material of carbon steel seamless steel pipe is carbon steel.

Carbon steel seamless pipe classification

Carbon steel seamless pipes are divided into Hot rolled seamless steel tubes, cold-rolled pipes, cold-drawn pipes, extruded pipes, top pipes, etc. according to different production methods, and all have their own process regulations.

Usage of carbon steel seamless steel pipes

Seamless steel pipes are widely used.

1.Seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel, or alloy structural steel, with a large production capacity.They are mainly used as pipelines or structural parts for conveying fluids ,For example, black steel pipe for gas lines can be used in natural gas pipeline engineering, water transmission pipeline engineering, and so on.

2. Supply is divided into three categories according to different purposes:

a. Supply based on chemical composition and mechanical properties;

b. Supplied according to mechanical properties;

c. Supply according to hydraulic test. Steel pipes supplied according to categories a and b, if used to withstand liquid motion, must also undergo hydraulic testing.

3. There are various types of seamless pipes for specialized purposes, including boiler seamless pipes, geological seamless steel pipes, and petroleum seamless pipes.

Manufacturing Process and Types of Carbon Steel Seamless pipe

The production process of seamless steel pipes is divided into the following steps:

Round tube blank → Heating → Piercing → Three roll oblique rolling, continuous rolling or extrusion → Tube detachment → Sizing (or reducing) → Cooling → Straightening → Hydrostatic testing (or flaw detection) → Marking → Warehousing.

Seamless steel pipes are made from steel ingots or solid billets that are perforated into tubes, and then hot-rolled, cold-rolled, or cold-drawn.

Seamless steel pipes are mainly divided into hot rolled seamless steel pipes, cold drawn seamless steel pipes, and cold rolled seamless steel pipes. This article mainly provides a detailed explanation of these three production processes.

Factors to consider when selecting carbon steel seamless pipelines

When selecting carbon seamless black steel pipes, several factors should be taken into account. These include the application requirements, operating conditions, pressure and temperature ratings, size and dimensions, and compliance with industry standards. Consulting with experts and reputable suppliers can help ensure the right selection.

1. Strength: Under a working pressure of 3MPa, the strength of the pipeline needs to meet certain requirements to ensure its safe operation. The strength of carbon steel seamless pipes is closely related to the wall thickness of the pipeline, and the larger the wall thickness, the higher the strength.

2. Corrosion resistance: Compressed air may contain certain amounts of moisture and impurities, which may cause corrosion to pipelines. Therefore, it is necessary to choose materials with good corrosion resistance.

3. Economy: The larger the wall thickness of the pipeline, the higher the material cost, and the weight of the pipeline will also increase, increasing the difficulty of transportation and installation. Therefore, it is necessary to choose economical and practical materials as much as possible while ensuring strength and corrosion resistance.

Taking into account the above factors, it is generally recommended to choose a reference wall thickness carbon steel seamless pipe under the guidance of the customer manager, which can meet the requirements of strength and corrosion resistance, while also having good economic efficiency. However, the specific selection still needs to be combined with actual situations, such as the length of the pipeline, support method, pipeline connection method, and other factors for comprehensive consideration. It is recommended to consult a professional engineer or manufacturer before selecting materials to ensure the safety and reliability of the pipeline.

Strict product inspection

Each steel pipe must pass the inspection layer by layer. Only the products that pass the inspection can leave the factory. Never let an unqualified product flow into the market.In addition to conventional water pressure testing and X-ray weld inspection experiments, we also conducted metallographic experiments, chemical composition testing, yield strength testing, tensile strength testing, impact testing, and other steel pipe inspection experiments, and recorded them.

Maintenance and Care | Tips for Extending the Lifespan of Carbon Steel Seamless Pipes

1. Store in a clean and unobstructed area away from factories and mines that produce harmful gases or dust

2. On the site, weeds and all debris should be removed, and thick walled steel pipes should be kept clean.

3. In the warehouse, materials that are corrosive to thick walled steel pipes such as acid, alkali, salt, cement, etc. should not be stacked together to prevent confusion and mutual corrosion.
