Safety of machinery - Safety requirements for tube forming and rolling mills and their finishing line equipment
|Publication Date:||1 July 2010|
|ICS Code (Equipment for the metallurgical industry):||77.180|
This European Standard describes the health and safety requirements of fully automated plant used in the process of tube forming, rolling and finishing (hereafter referred to as "plant"). It describes the foreseeable, significant hazards, hazardous situations, and events arising from plants and from particular machines integrated to form the plant; it does not describe the full health and safety requirements for each particular machine. It indicates preventive measures for avoiding the hazards and reducing the risks. It deals not only with circumstances where the machinery is used as intended, but also includes other conditions foreseen by the manufacturer, such as foreseeable faults, malfunctions or misuse.
This European Standard specifies the requirements to ensure the safety of persons which are to be met during the design, assembly, transport, commissioning, operation, maintenance and decommissioning of the equipment.
This standard assumes that installations are operated and maintained by adequately trained and competent personnel. Manual intervention for setting, adjustment and maintenance is accepted as part of the normal use of these machines.
This standard assumes that the machinery is used with adequate workplace lighting conforming to EN 12464-1 or to local regulations.
This standard applies to:
Automated plant and equipment operated for the production of metal seamless hot and cold finished tubes and welded tubes. A list of machines which could make up different plants is shown in Annex D (informative).
This standard covers:
For seamless hot-finished tubes: from material charging downstream of the heating furnace through the rolling process and up to, but not including any intermediate storage equipment or the downstream finishing lines.
For seamless cold-finished tubes: from material charging through the rolling process to the discharging equipment but not including any storage equipment.
For welded tubes: from coil charging through strip preparation, forming and welding equipment up to, but not including any intermediate storage equipment or the downstream finishing lines.
For the tube finishing line: from tube charging to the discharging equipment to the storage.
The following items are outside the scope of this standard:
- complete risk assessment of single machines which are used to form a plant
- quenching equipment;
- spiral tube manufacture;
- large diameter tube welding manufacture using three-roll bending machines, U-ing and O-ing press lines and their finishing lines;
- butt welding machinery for the manufacture of endless strips;
- irradiation units (material testing by e. g., ultrasonic and X-ray testing units);
- centrifugal casting machines;
- machine tools used for e. g., threading, chamfering, stamping and marking machines;
- storage equipment.
This standard does not establish any requirements concerning electromagnetic disturbances.
This standard is not applicable to tube rolling and forming mills and finishing line equipment, manufactured before the date of publication of this standard by CEN.
NOTE The words "Tube" and "Pipe" are synonymous in this standard.
