  • Quality Defects Analysis Of Welded Steel Pipe Welding Section

    The quality of welded pipes (SSAW/LSAW/ERW) is significantly influenced by the welding seam, which is considered the lifeline of these pipes. As such, it is imperative to conduct a comprehensive analysis and address quality defects related to the welded section.
  • Surface Treatment of SSAW Steel Pipe

    SSAW (Spiral Submerged Arc Welded) steel pipes are commonly used in various applications, and their surface treatment is essential to enhance durability, corrosion resistance, and overall performance. Here are some common surface treatments for SSAW steel pipes.
  • Quality Evaluation Process Of ERW Steel Pipes

    ERW (Electric Resistance Welded) steel pipes are made from steel coils or steel plates and the weld seam runs parallel to the pipe. They are commonly applied to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure. This article will introduce in detail the quality evaluation process of ERW steel pipes. Read on to learn more.
  • Connection Method Of Large Diameter SSAW Steel Pipe

    When welded steel pipe is manufactured, a steel plate or strip is bent and subsequently welded into either a circular, traditional pipe shape or a square shape, resulting in a seam on its body. Today, we will introduce in detail GB standards for welded steel pipes.
  • Double-sided submerged arc welding straight seam steel pipe (LSAW) production process

    Double-sided submerged arc welding straight seam steel pipe (LSAW) production process
  • Welded pipe process introduction

    Welded pipes are divided into spiral welded pipes and longitudinally welded steel pipes according to the forming process, and high-frequency resistance welding and submerged arc welding according to the welding process. Spiral welded pipes all adopt submerged arc welding process. For longitudinally welded pipes, submerged arc welded pipes are referred to as UOE, and longitudinal high-frequency resistance welding is referred to as ERW.
