Seamless Steel Pipe

Seamless pipe made of a single piece of metal with no seams on the surface is called a seamless steel pipe. According to the production method, the seamless pipe is divided into a hot rolled pipe, a cold rolled pipe, a cold drawn pipe, an extruded pipe, a top pipe, and the like. According to the shape of the section, the seamless steel pipe is divided into two types: a circular shape and an irregular shape, and the shaped pipe has a square shape, an elliptical shape and the like. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

Production technology of straight seam steel pipes

Straight seam steel pipes play a vital role in various industrial applications due to their durability and performance. Their production involves sophisticated technology divided into two major phases: the forming phase and the post-forming production phase. Each phase incorporates specific techniques and processes to ensure the quality and functionality of the final product.

Is carbon steel pipe a welded steel pipe?

Carbon steel pipe is not synonymous with welded steel pipe. Carbon steel pipe refers to a type of steel pipe made from carbon steel, an iron-carbon alloy containing less than 2.11% carbon. In addition to carbon, it may include small amounts of silicon, manganese, phosphorus, sulfur, and trace elements. This type of pipe is widely used in industries such as construction, bridges, railways, vehicles, ships, and machinery manufacturing. Carbon steel pipes can be categorized into two main types based on the manufacturing process: carbon steel welded pipes and carbon steel seamless pipes.

Weld parameters of welded steel pipe

A welded steel pipe is produced by crimping and welding steel plates or strips, typically with a length of 6 meters. The manufacturing process of welded steel pipes is straightforward, highly efficient, and cost-effective, requiring relatively low equipment investment. These pipes come in various types and specifications, but generally, their strength is lower compared to seamless steel pipes. Welded steel pipes are classified into straight seam welded pipes and spiral welded pipes (SSAW steel pipes) based on the type of weld used. They can also be categorized by the production method, such as arc welded pipes, electric resistance welded (ERW) pipes, high frequency or low frequency gas welded pipes, and furnace welded pipes.

Weld pitting of submerged arc welded steel pipe

Weld surface indentation in submerged arc welded (SAW) steel pipes refers to a defect where the weld surface is lower than the surrounding base material. This is a common issue in submerged arc welding, especially in the production of long weld seams such as those used in spiral submerged arc welded steel pipes, where welds can stretch for thousands of meters. Due to the continuous nature of the welding process, the occurrence of weld surface indentations is relatively frequent.

SSAW steel pipe weld eddy current nondestructive testing method

The eddy current nondestructive testing (NDT) method for Spiral Submerged Arc Welded (SSAW) steel pipes is used to detect surface defects, weld irregularities, and other potential flaws in the pipe’s material. This method is based on the principle of electromagnetic induction, where an alternating current (AC) is passed through a coil to generate a changing magnetic field. When this magnetic field interacts with the conducting material of the pipe, it induces eddy currents. Any changes in the pipe’s surface (such as cracks, weld defects, or variations in material properties) will disrupt the flow of these eddy currents, which can then be detected by the testing equipment.
