What are the cooling methods for large-diameter steel pipes?

Large-diameter steel pipes refer to those with an outer diameter of 1,000 mm or greater. Large-diameter seamless steel pipes are manufactured by piercing a steel ingot or solid billet, followed by hot rolling, cold rolling, or cold drawing.

Maintenance of steel plate rolled pipes is also very important!

Steel plate coiled pipe: As everyone knows, it is a highly practical stainless steel product, making it suitable for a wide range of applications. When not in use, steel plate coiled pipes should be stored safely, maintained, and handled with care. Avoid tossing them aside and then putting them away, as improper storage can lead to significant damage. Clearly, proper maintenance of steel plate coiled pipes is also crucial!

How is hot-rolled spiral steel pipe inspected before leaving the factory?

After spiral steel pipes are manufactured, it is essential to give full consideration to issues such as delivery, dispatch, and inspection. Compared with the actual production phase, these aspects may seem minor at first glance, yet they play a crucial role and should by no means be overlooked. Consequently, contracts must always be signed upon delivery of spiral steel pipes, which helps ensure the quality of this pipeline material. In fact, many of the advantages of this type of piping material are most clearly reflected in this stage.

What are the common lengths of spiral welded steel pipes?

Spiral steel pipes typically come in a standard length of 12 meters. In most applications, the quantity of spiral steel pipe is calculated based on this 12-meter length. Pipe specifications are indicated by the nominal diameter in millimeters; note that the nominal diameter may differ from the actual dimension. According to standards, there are two types of wall thickness: standard‑wall and thickened‑wall pipes.

Testing Methods for Spiral Tube Manufacturing Processes

Spiral pipes, also known as spiral steel pipes or spiral welded pipes, are manufactured by rolling low-carbon structural steel or low-alloy structural steel strips into a tubular blank at a specific helical angle—referred to as the forming angle—and then welding the seam. This process enables the production of large-diameter steel pipes from relatively narrow steel strips. So, what are the manufacturing processes and inspection methods for spiral pipes? Let’s take a look.

Methods for Surface Treatment of Spiral Tubes

Surface treatment methods for spiral pipes: 1. Cleaning Solvents and emulsions are used to clean the steel surface, removing oil, grease, dust, lubricants, and similar organic substances. However, this method cannot eliminate rust, scale, welding flux, or other contaminants from the steel surface; therefore, it serves only as a supplementary step in corrosion‑prevention processes.
