The forming angle of a spiral welded pipe is a crucial parameter. It refers to the acute angle between the centerline of the strip steel or coiled plate and the axis of the formed spiral welded pipe. The formula for calculating the forming angle (α) is as follows.

Seamless steel pipe (SMLS) production involves various processes, and regardless of whether the pipes are rolled, extruded, pressed, or spun, billet heating equipment is essential. This makes billet heating equipment a critical component in the seamless steel tube manufacturing process. Here, we discuss the key aspects of seamless steel pipe production equipment.

Heat treatment involves heating metal materials to an appropriate temperature, maintaining that temperature, and then cooling them in various ways. For carbon seamless steel tubes, the overall heat treatment is generally employed.

Spiral welded pipes are produced by rolling low-carbon or low-alloy structural steel strips into a tubular form at a specific helical angle, also known as a forming angle. To ensure the quality of large-diameter spiral welded pipes, several inspection methods can be employed.

When transporting steel pipes, careful inspection is essential, especially for anti-corrosion spiral steel pipes which must be checked multiple times before entering or leaving the warehouse. Then how should these pipes be inspected during warehouse entry and exit? What should be considered during their transportation, loading, and unloading? Here’s a comprehensive guide.

When transporting and handling anti-corrosion spiral submerged arc welded (SSAW) steel pipes, several important factors must be considered to ensure the integrity of the pipes and their protective layers. Here’s what you need to pay attention to.

Seamless steel pipes are crafted from a single piece of metal with no joints on the surface, formed by perforating a steel ingot or solid tube blank to create a capillary tube, which is then hot-rolled, cold-rolled, or cold-drawn. This article highlights the performance advantages of seamless steel pipes.

Yield strength is a crucial concept in the mechanics of seamless pipes. It represents the stress value at which a ductile material, such as seamless steel pipe, begins to deform permanently. This article will briefly introduce factors affecting the yield strength of seamless steel pipe.

The forming and sizing of seamless steel pipes are critical processes, and the design and adjustment of the hole can directly affect the quality of the pipes. When handling the forming of seamless steel pipes, the following eight points should be considered.

Carbon steel welded pipes are primarily produced using three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW), and straight seam submerged arc welding (LSAW). Each process has distinct characteristics, making them suitable for different applications based on raw materials, forming processes, caliber sizes, and quality.

Cold rolling involves processing steel plates or strips into various types of steel products through cold working methods such as cold drawing and cold bending at room temperature. Here's an overview of the cold drawn carbon steel pipe.

Seamless boiler tubes are a type of boiler tube that falls under the category of seamless steel tubes. Their manufacturing process is similar to that of other seamless tubes, but the steel grades used to produce these tubes must meet strict criteria.
