How are steel plate spiral pipes typically manufactured, and what applications do they serve?

How are steel plate spiral pipes typically manufactured, and what applications are they suitable for?

Steel plate rolled pipes are primarily composed of a winding drum, a drum shaft, a gear‑disc coupling (or a large gear), a drum hub, a bearing housing, and bearings.

1. Function of steel plate rolled pipes: Steel plate rolled pipes are an essential component of lifting machinery and equipment.

2. Structure of steel plate rolled pipes: Steel plate rolled pipes primarily consist of a drum, a drum shaft, a gear‑disc coupling (or a large gear), a drum hub, a bearing housing, and bearings.

3. Material for steel plate rolled‑tube fabrication: Crane Accessories Co., Ltd. specializes in manufacturing steel plate drums and other crane components. The material used for rolled‑tube fabrication is typically cast iron of grade HT20–40 or higher; for special applications, ZG25 or ZG35 cast steel may be employed, or Q235B and Q345B steel plates may be welded together.

Steel plate‑rolled pipes are manufactured by bending steel strips and then welding them together; they are commonly referred to as welded pipes. Based on their external shape, carbon steel pipes—also known as welded steel pipes or seam‑welded pipes—are typically made from ordinary carbon steel and feature a longitudinal weld along the entire length of the pipe. This type of pipe is called a seam‑welded pipe because it is formed in one step by heating and drawing strip steel. Carbon steel plate‑rolled pipes, on the other hand, are produced by rolling and joining sections of ordinary carbon steel sheet. They are well suited for low‑temperature, low‑pressure service fluids and are therefore termed carbon steel plate‑rolled pipes. These pipes are widely used in applications such as hydraulic cylinder manufacturing, signage, structural columns, and large‑diameter shaft machining. The wall thickness of standard plate‑rolled steel pipes generally ranges from 6 to 20 mm, while thicker walls—between 20 and 35 mm—are achieved through cold‑rolling processes.
