Process Characteristics of Spiral Tubes

Process Characteristics of Spiral Tubes

The raw materials for spiral pipe production include steel strip coils, welding wire, and flux. Before being put into service, these materials must undergo rigorous physical and chemical testing. At the head‑to‑tail joining stage, single‑wire or dual‑wire submerged arc welding is employed; during the post‑welding process after rolling into steel pipes, a fully automated submerged arc welding system is used. Prior to forming, the steel strip is subjected to leveling, edge trimming, edge flattening, surface cleaning, transport, and bending operations. An electrically‑controlled pressure gauge is utilized to regulate the pressure of the cylinders on both sides of the conveyor, ensuring smooth and stable strip conveyance.

Manufacturing Processes and Treatment Methods for Spiral Tubes

The manufacturing process of spiral pipes uses strip steel coils, welding wire, and flux as raw materials. Before being put into service, these spiral pipes must undergo rigorous physical and chemical testing. The butt welding of the strip steel is performed using single‑wire or dual‑wire submerged arc welding, while the back‑welding after the spiral pipe is rolled into a steel tube is carried out by automatic submerged arc welding. Prior to forming, the strip material is subjected to leveling, edge trimming, edge planing, surface cleaning, and specialized processing for transportation and bending. An electric contact pressure gauge is used to regulate the pressure in the cylinders on both sides of the conveyor, ensuring smooth conveyance of the strip steel.

Spiral pipe manufacturer: What are the methods for removing rust from spiral pipes?

Spiral pipe manufacturers state that chemical and electrolytic methods are used for pickling. Chemical pickling is employed solely for pipeline corrosion protection, effectively removing scale, rust, and old coatings. It may also serve as a post‑treatment step following sandblasting to remove rust. Although chemical cleaning can produce a clean, slightly rough surface, the resulting anchor profile is relatively shallow, making it prone to environmental contamination.

Spiral Pipe Manufacturer: Relevant Knowledge About Spiral Pipes

Spiral pipe manufacturers explain that spiral pipes, also known as spiral steel pipes or spiral welded pipes, are produced by winding 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. Below is an overview of relevant knowledge about spiral pipes for your reference.

Spiral Pipe Manufacturer: Production Process of Spiral Pipes

According to the manufacturer, spiral pipes can be categorized into several types based on their production process, including spiral-welded steel pipes, plastic-coated steel pipes, and straight-seam steel pipes. They are manufactured from steel coil stock and produced through a double-sided welding process, resulting in a circular steel pipe. The manufacturing of spiral pipes remains quite complex, involving numerous steps. So, what are the key stages in the production of spiral pipes? Let’s take a look!

Spiral Pipe Manufacturer: How Can You Prevent Wear When Using Spiral Steel Pipes?

Spiral pipe manufacturers emphasize that spiral steel pipes should be protected from abrasion during use, and their packaging must prevent loosening and damage throughout normal handling, transportation, and storage. Therefore, measures to prevent wear are of great importance, and we must employ the proper methods to avoid it. So, how can we minimize wear when using spiral steel pipes? Here’s an overview from the spiral pipe manufacturer.

Spiral Steel Pipe Manufacturer: What are the characteristics of straight-seam steel pipes?

2022/07/25

Spiral Steel Pipe Manufacturer: What are the characteristics of straight-seam steel pipes?

Spiral steel pipe manufacturers state that straight-seam steel pipes are primarily used in municipal water supply projects, the petrochemical and chemical industries, the power industry, agricultural irrigation, and urban construction. They are employed for liquid transport—both water supply and drainage—and for gas transport, including coal gas, steam, and liquefied petroleum gas. In structural applications, they serve as pile‑driving pipes and bridge components, as well as piping for docks, roads, and various building structures.

Spiral Steel Pipe Manufacturer: Some Basic Facts About Longitudinal Seam Steel Pipes

Spiral steel pipe manufacturers believe that the corrosion resistance of thick-walled straight-seam steel pipes and the extension of their service life have long been key concerns for pipeline designers and builders. Over nearly six decades of development, pipeline anti-corrosion technologies worldwide have largely reached maturity and stability. Steel pipes with an outer diameter-to-wall-thickness ratio of less than 20 are classified as thick-walled straight-seam steel pipes. They are primarily used as drill pipes for petroleum and geological exploration, cracking tubes in the petrochemical industry, boiler tubes, bearing tubes, and high-precision structural tubes for automobiles, tractors, and aerospace applications.
