TLP - Pressure vessels

This European Standard is applicable to the selection of bolting for equipment subject to the Pressure Equipment Directive 2014/68/EU.
It specifies standards and additional requirements for dimensions, materials and technical conditions of delivery for bolting.
The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN 1092 (PN designated flanges) and the series EN 1759 (Class designated flanges).
The selection is based on commonly used materials, bolts and nuts. It covers temperature ranges of the general service of standard flanges (based on PN or Class).
NOTE 1   The bolting selection given may be used in combination with non-standard flanges too provided that the range of application of the equipment for which the bolting is intended to be used is covered. It is the purchaser's option to decide on this.
When selecting bolting according to this European Standard it is essential to take into account other parameters such as type of fluids, corrosion hazards and relaxation at elevated temperatures.
The purpose of this European Standard is to provide a selection of most commonly used bolting types and bolting material combinations as well a tool for easy selection of suitable bolting for equipment.
It is not the intention to specify all possible applications but to give guidance on the most commonly applications. According to this, e.g. application limits for material in the creep range are not explicitly covered in this European Standard but some bolting materials listed (see Table 3, footnote h) are suitable to be used in this temperature range. Wherever the starting material standard provides mechanical properties for this temperature range respective reference is made in Table 3.
NOTE 2   Special services and ambient conditions may require the application of coatings. It is the purchaser's option to decide on this. Depending on the coating used, a verification of the temperature ranges

calculations as within a gasket type there will be differences
depending upon the supplier.

It is applicable to cylinder bundles containing cylinders containing compressed gas, liquefied gas and mixtures thereof. It is also applicable to cylinder bundles for acetylene. Additional requirements for acetylene cylinder bundles containing acetylene in a solvent are provided in Annex B. This document does not, however, cover acetylene cylinder bundles with solvent-free acetylene cylinders.

This Standard specifies the requirements for valve protection caps and valve guards used on cylinders for liquefied, dissolved or compressed gases. Valve protection caps and valve guards are some of the options available to protect cylinder valves, including valves with integral pressure regulators (VIPRs) during transport. This document is applicable to valve protection caps and valve guards which inherently provide the primary protection of a cylinder valve. It can also be used to test other equipment (e.g., handling devices) attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content. This document excludes protection devices for cylinders with a water capacity of 5 l or less and cylinders whereby the protection device is fixed by means of lugs welded or brazed to the cylinder, or is welded or brazed directly to the cylinder. This document does not cover valve protection for breathing apparatus cylinders. This document does not specify requirements that could be necessary to enable the valve protection device to be used for lifting the cylinder.

To allow ductile iron pipe manufacturers and users of the product to apply TMPO linings and thereby comply with the relevant requirements of EN 545, EN 545, EN 969. This demonstrates innovation according to Annex I, by the use of non-traditional coating systems offering environmental and economic benefits. The TMPO linings meet the criteria expressed in EN 14901, except for those pertinent to fusion bonded epoxy chemistry. The linings are being used in other parts of the world eg Australia and New Zealand and have been incorporated in the recent AWWA C116/A21.16-15 publication. The current status for TMPO linings in EU amounts to a barrier to trade and does not support SME’s involved in the manufacture, lining and application of the material that offers human health benefits, as highlighted in the Annex I and II.

This European Standard defines the requirements and test methods for factory applied epoxy coatings (fusion bonded powder or liquid two-pack) used for the corrosion protection of ductile iron fittings and accessories conforming to EN 545, EN 598, EN 969, EN 12842, EN 14525, for:
-   conveying water (e.g. potable water) at operating temperature up to 50 °C excluding frost; or
-   conveying waste water at operating temperature up to 45 °C excluding frost; or
-   conveying gas at operating temperature up to 50 °C;
-   suitable for external environments, i.e. soils, waters and atmospheres of all common corrosion loads, characterized in EN 545:2010, D.2.3.
