Hot sale QSTE500TM welded steel pipe cold bending welded round steel pipe

Welded round pipe is a product that connects a metal strip (usually a steel strip) with two open ends into a circular pipe through a welding process. During the welding process, the metal strips at both ends are melted and joined together to form a seamless, closed pipe structure.

Welded round tubes are usually made of various types of steel. Steel is a material with good mechanical properties, plasticity and corrosion resistance, so it is widely used in the manufacture of welded round pipes.

Advantage of welded steel pipe:

1. Strength: The welds of welded round tubes are fused in the welding process to form a continuous structure, so welded round tubes usually have good strength and compressive resistance.

2. Cost: Welded round tubes are cheaper than seamless tubes. Seamless pipe production requires a high cost and complex production process, while the production process of welded round pipe is relatively simple, high production efficiency, so the cost is low, suitable for large-scale production.

3. Production efficiency: The production speed of welded round tubes is faster, especially when using efficient welding technologies (such as LSAW and SSAW), the production efficiency is higher. In contrast, the production process of seamless pipes is more cumbersome and the production speed is relatively slow.

Quality Assurance:

1. Raw material selection: For the production of welded round pipes, the selection of high-quality steel plates and pipes is key. The chemical composition and mechanical properties of raw materials need to meet relevant standards, and strict quality inspection is carried out to ensure the weldability and mechanical properties of raw materials.

2. Production process control: The production process of welded round pipes needs to strictly control various process parameters, such as welding temperature, welding speed, current and voltage. Adopt advanced welding equipment and process to ensure welding quality and consistency.

3. Welding process monitoring: In the welding process, it is necessary to conduct real-time monitoring and control, as well as timely correction of possible problems. Automatic monitoring equipment is used to monitor welding temperature, welding energy, weld quality, etc., to ensure the stability and reliability of the welding process.

4. Finished product inspection: The finished product of welded round pipe needs to be comprehensively inspected, including weld inspection, dimensional inspection, mechanical property testing, etc. In the inspection of finished products, a combination of non-destructive testing and destructive testing is usually adopted to ensure product quality.

Application:

1. Oil pipelines: Welded round pipes are widely used in pipeline systems for transporting oil and natural gas.

2. Natural gas pipelines: Similar to oil pipelines, welded round pipes are also widely used in the construction of natural gas pipelines.

3. Oil and gas equipment: Welded round pipes are also used in the manufacture of oil and gas equipment, such as storage tanks, pressure vessels, pipe connectors, etc.
