Seamless Cylinder Technical Requirements

Seamless cylinder technical requirements typically refer to the technical standards and requirements needed to manufacture seamless cylinders. These requirements include, but are not limited to, the following:

Raw material quality requirements: seamless steel cylinder raw materials are usually high-strength steel, the material is required to have good toughness, tensile strength and corrosion resistance.

Manufacturing process requirements: including heat treatment of steel, extrusion molding, forging, rolling and other processes to ensure that the seamless cylinder has the right dimensional accuracy, surface quality and internal structure.

Welding technology requirements: for some seamless cylinder components need to be welded, the welding process is required to be stable, welded joints are strong and free of defects.

Heat treatment requirements: including quenching, tempering and other heat treatment processes to improve the strength and toughness of the steel, to ensure that the seamless steel cylinder has good safety performance in use.

Surface treatment requirements: clean and polish the internal and external surfaces of seamless steel cylinders to ensure that the surface is smooth, no scratches, no oxides and other defects.

Quality testing requirements: including non-destructive testing, pressure testing, sealing testing, etc., to ensure that the quality of seamless steel cylinders comply with the relevant standards and regulations, and have good safety performance.

Marking requirements: The model, specification, manufacturer, production date and other information must be clearly marked on the seamless steel cylinder for traceability and management.

These technical requirements are usually set by relevant standardization organizations or industry associations, such as the International Organization for Standardization (ISO), the American Welding Society (AWS), and the Chinese Standardization Organization (GB/T). Manufacturers need to strictly follow these requirements to ensure the quality and safety performance of seamless cylinders.
