Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, and the length is generally 6 meters. Welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless steel pipe.

Commonly used materials for welded pipes are: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.

With the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welds has been continuously improved, the varieties and specifications of welded steel pipes have been increasing, and seamless steel pipes have been replaced in more and more fields. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld. Classification by production method: process classification - arc welded pipe, electric resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.

The blanks used for welded steel pipes are steel sheets or strips, which are divided into furnace welded pipes, electric welded (resistance welded) pipes and automatic arc welded pipes due to their different welding processes. Due to the different welding forms, it is divided into two types: straight seam welded pipe and spiral welded pipe. Because of its end shape, it is divided into circular welded pipe and special-shaped (square, flat, etc.) welded pipe.

Application

liquid delivery (pump well, gas, water), construction pipe, structural pipe(greenhouse structure, fence post), curtain wall, machinery part ect.

The main application areas of carbon steel pipes are:

1) Construction field

1. Structural support: Carbon steel pipes are often used for structural support of buildings, such as bridges, buildings, etc. Because carbon steel pipes have high strength and rigidity, they can withstand greater pressure and loads, making buildings more stable and safer.

2. Piping system: Carbon steel pipes play an important role in the piping system of buildings. It can be used to transport water, gas, oil and other fluids. It has good corrosion resistance and sealing performance and can ensure the normal operation of the pipeline system.

3. Decorative materials: Carbon steel pipes have a smooth appearance and good texture, and are often used in interior decoration, such as stair handrails, railings, etc. Not only does it have a beautiful appearance, it is also durable and easy to maintain.

2) Machinery manufacturing field

1. Automobile manufacturing: Carbon steel pipes are widely used in automobile manufacturing, such as body structure, chassis, engine exhaust system, etc. Carbon steel pipes have high strength and rigidity, can provide good safety and stability, and at the same time have low cost and good processability.

2. Mechanical equipment manufacturing: Carbon steel pipes play an important role in mechanical equipment manufacturing. It can be used to manufacture various parts such as bearings, gears, shafts, etc. Carbon steel pipes have good mechanical properties and wear resistance and can meet the requirements of mechanical equipment.

3. Pipeline transportation: Carbon steel pipes can be used to transport various fluids and gases, such as oil, natural gas, water, etc. It has good corrosion resistance and high strength, which can ensure the safe and reliable operation of the pipeline system.

3) Energy field

1. Oil and natural gas mining: Carbon steel pipes are widely used in oil and natural gas mining. It can be used in oil well casing, oil pipelines, etc. It has the characteristics of high temperature resistance, corrosion resistance and pressure resistance, and can ensure the safe transportation of oil and natural gas.

2. Power transmission: Carbon steel pipes can be used to support and protect power transmission lines. It has good electrical conductivity and mechanical properties, can withstand the transmission of high voltage and large current, and ensures the normal operation of the power system

The advantages of carbon steel pipes mainly include the following aspects:

1. High-strength 

2. Good processability

3. Good corrosion resistance 

4. Economical and practical

5. Recyclable and reusable
