This European Standard specifies dimensions, tolerances, materials, internal and external surface characteristics, and marking of stainless steels longitudinally fusion welded tubes for the food and chemical industry
This European standard specifies requirements for two types of hose and hose assembly identified by their maximum working pressures and main use i.e. Type 1 is for road and rail tanker use and Type 2 is for dockside use. The types are further divided into two classes related to the maximum temperature of the product to be conveyed. The hose constructions may be smooth or rough bore.
NOTE These types of hose or hose assemblies may not necessarily be suitable for all types of petroleum based products or coal tar, or products containing coal tar.
This European Standard specifies materials and test requirements for tube connections with press fittings made of unalloyed steel.
This European Standard specifies press fittings in the size range 12 mm to 108 mm for the purpose of joining unalloyed steel tubes intended for use in heating and cooling systems, wet sprinkler systems, oil transporting and compressed air.
Permissible operating temperatures and maximum operating pressures are also established.
Fittings may comprise a combination of end types, specified in this standard or other standards, providing they are suitable for the fluid /air being conveyed.
The standard establishes a designation tube system with press end joints made with the components fitting and tube, pressed with a pressing tool.
This standard is applicable to press fittings for joining unalloyed steel tubes to EN 10305-3, EN ISO 2081, EN 10346.
Fittings may be suitable for joining other metallic tubes provided the press fitting joint with the specified tube meets the requirements of this standard.
This European Standard describes the specific functional requirements for the design, construction, operation, maintenance and disposal activities for safe and secure gas compressor stations.
This European Standard applies to new gas compressor stations with a Maximum Operating Pressure (MOP) over 16 bar and with a total shaft power over 1 MW. For existing compressor stations this European Standard applies to new compressor units. Where changes/modifications to existing installations take place, due account may be taken of the requirements of this European Standard.
This European Standard does not apply to gas compressor stations operating prior to the publication of this European Standard.
The purpose of this European Standard is intended to
— ensure the health and safety of the public and all site personnel
— to cover environmental issues and
— to avoid incidental damage to nearby property.
This European Standard specifies common basic principles for the gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or codes of practice may exist in the CEN member countries.
This European Standard specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countries.
This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, the national legislation/regulation shall take precedence as illustrated in FprCEN/TR 13737. FprCEN/TR 13737 gives:
— clarification of all legislations/regulations applicable in a member state;
— if appropriate, more restrictive national requirements;
— a national contact point for the latest information.
This European Standard does not apply to:
— off-shore gas compressor stations;
— gas compressor stations for compressed natural gas filling-stations;
— customer installations downstream of the point of custody transfer;
— design and construction of driver packages (see Annex C).
For supplies to utility services such as small central heating boilers reference should be made to EN 1775.
Figure 1 shows a schematic representation of compressor stations in a gas infrastructure.
This European Standard specifies the rating conditions, tolerances and the method of presenting manufacturer’s data for positive displacement refrigerant compressors. These include single stage compressors and single and two stage compressors using a means of fluid subcooling. This is required so that a comparison of different refrigerant compressors can be made. The data relate to the refrigerating capacity and power absorbed and include correction factors and part-load performance where applicable.
This Part of EN 13480 specifies requirements for industrial piping systems made of aluminium and aluminium alloys in addition to the general requirements for industrial piping according to the series of standards EN 13480 and CEN/TR 13480-7.
This International Standard specifies the requirements for the periodic inspection of acetylene cylinders with and without solvent.
