In recent years, significant international research and analysis have focused on the development and application of X80 grade seamless line pipeline for large-diameter, high-grade natural gas pipelines. The main findings are as follows.

Welding ERW (Electric Resistance Welded) pipes during winter necessitates specific precautions to ensure quality and avoid defects due to cold temperatures. Follow these steps for optimal results.

Steel pipes are classified into two main types based on their manufacturing process: Longitudinal Submerged Arc Welding (LSAW) pipes and Seamless (SMLS) pipes. Understanding the differences between these two types is essential for selecting the appropriate pipe for specific applications. Below is a detailed comparison of LSAW and SMLS steel pipes, focusing on their concepts, classifications, manufacturing processes, and applications.

High-pressure boiler tubes are mechanical devices designed to generate high-pressure steam by converting thermal and kinetic energy. This article will briefly introduce how high pressure boiler tubes work.

Welded pipe refers to a pipe manufactured by cutting steel plates or steel strips to a specific length according to relevant national standards or specifications. This article will briefly introduce the definition and industrial use of welded steel pipe.

Producing seamless steel pipe requires careful attention to various steps to ensure high-quality output. Here are the key steps involved in the production process.

Anticorrosion measures are critical in the oil and gas industry to ensure the longevity and integrity of seamless line pipes. Proper construction and maintenance regulations help prevent corrosion, reduce operational risks, and enhance the safety and efficiency of pipeline systems. Below are the key regulations and best practices for anticorrosion construction of seamless line pipes in the oil and gas industry.

Welded steel pipe, commonly known as welded pipe, is manufactured by welding crimped and formed steel plates or strips. This straightforward and efficient production process requires minimal investment in equipment, making welded pipes widely used across various industries. However, several factors influence the market price of welded steel pipes.

Producing Longitudinal Submerged Arc Welded (LSAW) steel pipes involves several critical pieces of equipment to ensure precision, quality, and efficiency. The main equipment used in the production process are as follows.

Seamless steel pipes generally lose their load-bearing capacity at temperatures between 450-650 °C, leading to significant deformation. Below are several fire protection measures for seamless steel pipes.

When choosing between carbon steel Electric Resistance Welded (ERW) pipes and Spiral Submerged Arc Welded (SSAW) pipes, it's important to understand their differences in production process, raw materials, procurement costs, and geometric size. Here’s a detailed comparison.

In the ultrasonic inspection of longitudinally submerged arc welded (LSAW) steel pipes, distinguishing between defect and non-defect signals is crucial. This article will briefly introduce ultrasonic testing of LSAW steel pipe.
