SSAW (Spiral Submerged Arc Welding) steel pipe is a type of welded steel pipe made from strip steel coils. Appearance inspection is a simple yet essential method for assessing SSAW pipe quality, primarily identifying surface defects and dimensional deviations.

According to the anti-corrosion coating standards for large-diameter submerged arc steel pipes, the methods for surface treatment of these pipes are continuously improved. This article discusses the various techniques for removing surface impurities from submerged arc welded steel pipes.

This article will briefly introduce the purpose of SSAW steel pipe preheating.

In water supply systems, SSAW steel pipes need effective anti-corrosion measures to ensure longevity and safety. Here are some commonly used methods.

Here's an overview of the DIN 17175 ST35.8 boiler tubes.

DIN 17175 is a German standard that specifies the requirements for seamless steel pipes used in high-temperature service. These pipes are designed for applications where high heat resistance and durability are essential, such as in the construction of boilers, pipelines, pressure vessels, and equipment for service up to 600°C and at simultaneous high pressures.

Here's an overview of the JIS G3454 carbon steel pipes for pressure service.

This article will discuss the characteristics, manufacturing process, and applications of API 5L SCH 80 spiral welded pipes.

API 5L line pipe is a specification developed by the American Petroleum Institute (API) for steel pipes used in the transportation of petroleum, natural gas, and other fluids. These pipes are essential for the oil and gas industry, providing a reliable and efficient means of transporting these resources from production sites to refineries and distribution centers. This article will discuss the materials used in API 5L line pipes.

The flattening test is a crucial quality assurance procedure for Electric Resistance Welded (ERW) pipes. This test evaluates the material's ductility and the quality of the weld seam by subjecting a sample of the pipe to compressive deformation. The goal is to ensure that the pipe can withstand mechanical stresses during its intended application without failure.

Welding steel pipes is a critical process in construction, manufacturing, and repair. To ensure welding quality and safety, several key considerations must be addressed during the welding operations.

Heat exchanger boiler tubes are essential components in industrial boilers, primarily used in heat exchange processes. These tubes are typically arranged in bundles, allowing high-temperature flue gas or water vapor to flow through them. This setup enables the transfer of heat to water or other media (such as feed water in steam generators) flowing outside the tubes, ensuring efficient heat utilization and conversion.
