API 5L SSAW Welded Spiral Steel Pipe

API 5L SSAW (Submerged Arc Welding) spiral steel pipe is a carbon steel pipe that meets the API 5L specification. It is commonly used in the oil and gas industry for the transportation of hydrocarbons and in other industries such as water supply, construction and structural applications.

The SSAW welding process involves forming a spiral weld by feeding a continuous strip of steel through a series of rolls and then welding the edges together with submerged arc welding. The result is a strong and durable joint that can withstand high pressures and stresses.

API 5L SSAW spiral steel pipe is available in various diameters and wall thicknesses. It is suitable for transporting large quantities of liquids and gases over long distances. The spiral shape of this pipe allows it to be installed in a more flexible manner, as it can easily be bent to follow the contours of the terrain. This makes it ideal for applications where pipelines need to be installed around obstructions or in areas that are difficult to access.
