Causes of Certain Issues in Spiral Pipe Production

What are the common causes of production problems in spiral pipes? During smelting or hot working, certain factors—such as non-metallic inclusions, gases, improper process selection, or incorrect operating procedures—can give rise to internal or surface defects in the steel. These defects severely compromise the quality of the material or finished product and may even result in scrap.

What are the characteristics of using anti-corrosion spiral pipes for potable water pipelines?

When tap water flows through steel pipes, it exerts significant impact on the pipeline. Conventional steel pipes are prone to damage under such pressure, whereas spiral-welded pipes, with their exceptional toughness, can withstand much higher pressures.

How is rust removed from straight-seam pipes?

In the anti-corrosion construction of oil and gas pipelines, surface treatment of longitudinal‑seam pipes is one of the key factors determining the service life of the pipeline’s corrosion protection; it is also a prerequisite for ensuring strong adhesion between the protective coating and the pipe. According to research by specialized institutions, the service life of an anti-corrosion coating depends on such factors as coating type, coating quality, and the construction environment. Surface treatment of longitudinal‑seam pipes accounts for approximately 50% of the influence on the coating’s service life; therefore, surface‑treatment methods must be continuously refined in strict accordance with the requirements specified in the anti-corrosion coating standards.

How should the raw materials for steel plate spiral pipes be selected?

Producing steel‑plate coiled pipes requires certain raw materials. To ensure the quality of these products, we must pay close attention to every detail of the manufacturing process, starting with the fundamental raw materials. After all, raw materials form the foundation; only with high‑quality inputs can we guarantee consistent performance in subsequent stages. Moreover, selecting appropriate raw materials for steel‑plate coiled pipes does not mean that any material will suffice—choosing the right ones is essential. It is imperative not to cut corners on raw materials, as doing so can compromise production quality. Below are some key principles to consider when manufacturing steel‑plate coiled pipes, for your reference:

What is the bend test for steel plate rolled pipes used to assess?

2021/11/16

What is the bend test for steel plate rolled pipes used to assess?

The bend test for steel plate rolled pipes is primarily used to determine the bending strength of brittle and low‑ductility materials (such as cast iron, high‑carbon steel, and tool steel) and to assess deflection, which serves as an indicator of ductility. The bend test can also be employed to evaluate the surface quality of the material.
