1 General
This standard presents flow substances used in the project, their media codes, piping
materials specified for different flow substances, pipe classes, flange gasket material,
hand valve types and materials for valve body, closing device and seat and leakage
rates.
The operation and design values for pipelines will be specified in a separate pipe line list.
The abbreviations and codes in Appendix I are presented in the following Chapters 2…6.
The code consists of letters and numerals. The codes and media names are based on
the existing fluids at the mill.
Flow substances and their codes are divided into the following main categories:
1 Airs
2 Additives
3 Condensates
4 Chemicals
5 Effluents
6 Feed waters
7 Gases
8 Liquors
9 Oils and Fuels
10 Pulps
11 Solids
12 Steams
13 Waters

SP Sampling
The valves shall be CE marked to the extent required by the Pressure Equipment
Directive (PED) 2014/68/EU classification.
Valve types shall be tested in use and found well-tried reliable types.
Dependent on the process conditions, may gear also be required for smaller dimensions.
Valves on suction pipelines to the pumps shall be of full bore type, such as ball valve,
knife gate valve, etc.
Ball valves DN < 100 shall be delivered with long weld ends if not otherwise agreed.
Valves are not allowed to be welded to each other without piece of pipe in between them.
The flow port of ball valves with core ball shall be tubed for media that cause plugging,
also for high consistency stock > 10 %.
For stock > 3.0 % valve types with a full port shall be used.
In stock lines butterfly valves between flanges shall be equipped with metal seals and
with a cutting closing movement of the disc.
One-part welded ball valves DN < 100 with reduced bore may only be used for media
with low viscosity and without impurities or abrasive particles.
The leakage rates of the valves are based on the standard EN 12266-1. The leakage
rates shall be A for soft seated valves and B for hard seated valves if not otherwise
specified.
Main shut-off valves shall be equipped with locking device for lockout by LOTO padlock.
Diameter of hole for padlock shall be minimum 7 mm.
