How are steel plate rolled pipes manufactured, and what applications do they serve? Steel plate rolled pipes primarily consist of a roller, a roller shaft, a gear‑disc adapter (or large gear), a roller hub, a bearing housing, and bearings.

　　 Steel plate rolled pipe How is it manufactured? What applications does it cover? Steel plate spiral pipes are primarily composed of a roller, a roller shaft, a gear‑disc adapter (or large gear), a roller 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. Steel plate rolled pipe structure: The steel plate rolled pipe primarily consists of a drum, a drum shaft, a gear‑disc adapter (or large gear), a drum hub, a bearing housing, and bearings.

　　3. Materials for steel plate rolled pipe fabrication: Crane Accessories Co., Ltd. specializes in manufacturing steel drums and other crane components. The material used for rolling is typically cast iron of grade no lower than HT20‑40; for special applications, ZG25 or ZG35 cast steel, or Q235B/Q345B steel plates welded together, may be employed.

　　Steel plate‑rolled pipe is manufactured by bending and welding steel tubes; it is commonly referred to as welded pipe. Based on its external shape, carbon steel pipe—more accurately termed welded steel pipe or seam‑welded pipe—is made from ordinary carbon steel. The entire pipe features a longitudinal seam, formed in a single pass by heating and stretching strip steel; this is known as a seam‑welded pipe. Steel plate‑rolled carbon pipe is produced by rolling and joining individual sheets of ordinary carbon steel. It is suitable for low‑temperature, low‑pressure service and is called steel plate‑rolled carbon pipe. It is primarily used in industries such as hydraulic cylinder manufacturing, signage production, structural columns, and heavy‑duty shaft machining. The wall thickness of coiled steel pipe typically ranges from 6 to 20 mm, while thicker sections are processed to 20–35 mm using cold‑rolling techniques.

　　Steel plate coil tubing is primarily targeted at large‑scale customers; most end users lack the equipment to uncoil it or face usage constraints. Consequently, downstream processing of steel plate coil tubing represents a highly promising industry.
