Welded Steel Pipe

what is a weled steel pipe?


Welded steel pipe is a type of steel pipe that is formed by welding two or more pieces of steel together. The welding can be done using various methods such as electric resistance welding, submerged arc welding, and high-frequency induction welding.


Welded steel pipes are used for various applications such as transporting fluids and gases in pipelines, structural support for buildings and bridges, and as casing for oil and gas wells. They are available in various sizes and thicknesses, and can be made from different grades of steel to suit different applications.


Seamless steel pipe VS welded steel pipes


Compared to seamless steel pipes, welded steel pipes are generally more cost-effective, but may have slightly lower strength and durability. However, modern welding techniques and high-quality materials have made welded steel pipes a reliable and durable option for many applications.



Specifications about weld steel pipe


Welded steel pipe is a type of pipe made from steel plates or strips that are welded together to form a continuous tube. This type of pipe is commonly used in various industries, including oil and gas, construction, and transportation. Here are some specifications about weld steel pipe:


  1. Size range: Welded steel pipes can be produced in a wide range of sizes, from small diameter pipes with a few millimeters in diameter to large diameter pipes with several meters in diameter.

  2. Wall thickness: The thickness of the pipe wall can vary depending on the application and requirements, ranging from thin-walled pipes used for low-pressure applications to thick-walled pipes used for high-pressure applications.

  3. Material: Welded steel pipes can be made from a variety of materials, including carbon steel, stainless steel, and alloy steel.

  4. Manufacturing process: Welded steel pipes can be produced using several manufacturing processes, including electric resistance welding (ERW), submerged arc welding (SAW), and seamless welding.

  5. Coating: Welded steel pipes can be coated with different types of coatings to protect the pipe from corrosion and improve its durability. Some common coatings include galvanized, epoxy, and polyethylene coatings.

  6. Standards: Welded steel pipes must meet various standards depending on the application and country of use. Some common standards include API 5L, ASTM A53, and EN 10217.

  7. Uses: Welded steel pipes are used in a wide range of applications, including transporting fluids and gases, structural support, and manufacturing equipment.

 Types of weld steel pipe

There are several types of weld steel pipes, including:


  1. ERW (Electric Resistance Welding) Pipe: This type of pipe is produced by rolling a sheet of steel into a cylindrical shape and then welding the edges together using an electric current. ERW pipes are commonly used for low-pressure applications such as water, gas, and oil transportation.

  2. LSAW (Longitudinal Submerged Arc Welding) Pipe: This type of pipe is produced by bending and shaping a steel plate into a cylindrical shape and then welding the edges together using a submerged arc welding process. LSAW pipes are commonly used for high-pressure and high-temperature applications such as oil and gas transportation.

  3. SSAW (Spiral Submerged Arc Welding) Pipe: This type of pipe is produced by forming a spiral-shaped steel plate and then welding the edges together using a submerged arc welding process. SSAW pipes are commonly used for conveying fluids such as water, gas, and oil.
