Carbon Steel Pipe Manufacture in China: Guarantee the material

Carbon steel pipe is one of the best-selling products,it also has a wide range of application scenarios. One of the most important indicator of carbon steel pipes is its material.

  • Inspection reports of Raw material must correspond to batches, so the source is traceable.

  • In the producing process, all the key points are recorded, so the process is traceable.

  • Each test is completed and recorded.

  • 100% testing of finished products.

What is Carbon steel pipe?

Carbon steel pipe is one type of durable material which is made of carbon steel. Carbon steel is a steel alloy consisting of iron and steel. Due to its high strength and pressure, carbon steel pipes are widely used for liquid transport of various heavy industries such as infrastructure, shipping, distiller, chemical fertilizer equipment, petroleum, oil and others.

Carbon steel pipes provide safety and durability. It is an ideal material for structural application because of its impact resistance, which won’t be affected by harsh environmental conditions such as pressure or extreme weather.

Carbon Steel Pipe: Classify according to manufacturing ways

Carbon steel seamless pipe

Carbon steel seamless pipe is made of carbon steel , its main component elements include carbon, silicon, manganese and other elements. Adding carbon elements that will make carbon steel seamless pipes have the features of high strength, pressure resistance, high temperature resistance, etc.

Longitudinal weld steel pipe

Longitudinal weld steel pipe, its surface has one weld seam parallel to the longitudinal direction of the steel pipe. It’s always used in low-pressure pipeline.Generally the raw material of longitudinal weld steel pipe is steel roll or steel plate. They are formed by forming a machine to cylinder and then welding.

Spiral weld steel pipe

Spiral weld steel pipe is also one type of weld steel pipe, which is manufactured based on strip steel as raw material through heating under normal temperature to form and welded by automatic double-wire submerged arc welding process. It is mainly used for liquid transportation with low pressure.

Carbon Steel Pipe type - Classify as shape

Round carbon steel pipes

Round carbon steel pipes are the common materials for pipeline of liquid transportation, petroleum exploitation, construction, ship building, machine manufacturing, and mining. Because most of the pipes have good mechanical properties and corrosion resistance.

Square carbon steel pipe

Square carbon steel pipe is a common building material that has extensive use in construction and machine manufacturing due to it having good performance in mechanical capacity and corrosion resistance. Square carbon steel pipe also has two types: seamless and weld.

Carbon Steel Pipe type - Classify as Size

Features

Carbon steel pipe is very easily manufactured that makes it a material with a wide arrangement. It is also easy to cut and bend to fit anywhere you need it as well as it can be easily connected to joints, valves and other pipe fittings. The following are some features about it.

Tensile strength

Carbon steel pipe has high tensile strength and can support greater tension.

High temperature resistance

The carbon steel pipe for high temperature service has good heat resistance.

Corrosion resistance

By adding appropriate alloying elements, carbon steel pipes have good corrosion resistance and are suitable for a variety of corrosive media.

Machinability property

Carbon steel pipe has good machinability performance that makes it easily manufactured in a variety of shapes to meet different needs.

Connection performance

Carbon steel pipe has good connection properties and can be connected with pipe fittings through welding, threaded connection etc.

Low temperature resistance

The carbon steel pipe for low temperature service won't shrink or deform obviously in a low temperature environment.

Economical

The price of carbon steel pipe is relatively low and has good economical efficiency.

Applications

Petroleum and gas industry: carbon steel pipes play very important roles in the petroleum and gas industry. They are used for transporting petroleum and gas and have good corrosion resistance and high tensile strength.

Chemical industry: Carbon steel pipes can be used in the chemical industry to transport acids, alkalis and other chemical media. Its strong corrosion resistance can ensure the safe transportation of media.

Construction industry: Carbon steel pipe also has extensive use in the building field, such as it can be used for the support of building structures and the load-bearing of bridges.

Quality Assurance

1) To ensure the quality of carbon steel pipes, we need to ensure the material first. We only buy the material form large qualified factory.

2) In producing process, every step must carried out in according to the stander. 100% Productions need to pass the test, including wall thickness, diameter and others.

3) If the customer needs the testing of international third-party testing companies such as BV,SGS, our company will cooperate with the whole process, and let the inspector complete the testing in a fair and impartial manner.

4) Package is also very important. We must strengthen the package, so you can receive the best goods after long sea voyage.
