Product Introduction

Welded carbon steel pipe is made of carbon steel strip or steel plate, and is made by coiling, high-frequency resistance welding (ERW), submerged arc welding (LSAW) or spiral welding (SSAW). It has the advantages of efficient production and economy. Its manufacturing process is flexible, and it can produce pipes with a wide range of diameters (from DN15 to DN2500 and above), and the cost is significantly lower than that of seamless pipes. It is especially suitable for medium and low pressure and non-rigorous working conditions.

According to the welding method, welded carbon steel pipes can be divided into straight seam welded pipes and spiral welded pipes. The weld of straight seam welded pipe is straight, the structure is simple, and the pressure bearing capacity is relatively balanced. It is mostly used in urban pipelines, building supports and general fluid transportation; the weld of spiral welded pipe is spiral, and the length of a single pipe is longer. It is suitable for large-diameter oil and gas pipelines and areas sensitive to geological subsidence. Both types of pipes need to be ensured by means of radiographic inspection, ultrasonic testing and other means to ensure the quality of the welds, and some areas also need to be treated with anti-corrosion coatings to extend the service life.

Advantages of Welded Carbon Steel Pipe

1. Low cost

The main components of carbon steel pipes are iron and carbon. Compared with materials such as stainless steel and alloy steel, the raw material and processing costs are lower, and they are suitable for large-scale engineering applications.

2. Mature welding process

The welding technology of carbon steel pipes has been developed for a long time, and the process is mature and easy to operate. Commonly used methods such as arc welding and gas shielded welding (such as MIG/MAG, TIG) can be applied, with high welding efficiency and relatively low equipment requirements.

3. Material plasticity is strong

Carbon steel pipes are easy to cut, bend and form, and have good processing performance before and after welding. They can adapt to the construction needs of complex structures, especially in pipeline laying or special-shaped component manufacturing.

4. Stable mechanical properties

Low carbon steel pipes (such as Q235, Q345) have high strength after welding and can meet the load-bearing requirements of most structural parts, such as building frames, bridge supports, etc. Medium carbon steel pipes are suitable for scenes that require higher strength.

5. Wide applicability

Carbon steel pipe welded joints have reliable performance in conventional environments (such as room temperature and non-strongly corrosive media), and are widely used in oil and natural gas transportation, water supply and drainage systems, machinery manufacturing and other fields.

6. Easy to repair and modify

If there are defects in the welding part, the repair cost of carbon steel pipe is low and the technical difficulty is relatively low. The problem can be quickly solved by repair welding or partial replacement.

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Applications of Welded Carbon Steel Pipe

1.Water supply system

Carbon steel welded pipes are often used to construct urban water supply networks, including drinking water supplies and the transmission of other non-corrosive liquids. Its good sealing and corrosion resistance ensure the safety of water quality and the stable operation of the system.

2.Drainage system

Carbon steel welded pipes are also suitable for drainage systems such as sewage discharge and rainwater collection. Its high strength and compression resistance can withstand large water pressure and scouring force.

3.Oil and gas transportation

Carbon steel welded pipe can reliably transport oil and natural gas in high-pressure environments. Its sealing and corrosion resistance ensure safety and stability during transportation.

4.Chemical Industry

Carbon steel welded pipes are also common in chemical production because of their ability to resist corrosion and erosion from some chemicals. At the same time, its high strength and temperature resistance are also suitable for some special chemical processes.

5.Heat and steam delivery

Where high-temperature media transfer is required, such as heat exchanger circuits in power plants, carbon steel welded pipes can be used. Its high temperature resistance ensures the stable operation of pipelines in high temperature environments.

6.Construction sector

Carbon steel welded pipes are also widely used in the construction field, such as hot water supply, heating systems, air conditioning ducts, etc. Its excellent thermal insulation performance and durability make the operation of building systems more efficient and reliable.
