PSK 4201 - Pipe classes. Definition
A pipe class denotes the selection of such pipes
and fittings as may be used for one and the same
pipeline, in which selection their dimensions and
materials have been defined.This standard presents the material designations to
be used for the pipe classes, as well as the
designations of standardised pipe classes.Piping components belonging to pipe classes are
straight pipes, elbows, reducers, tee pieces,
branch connections, collars, flanges, caps,
threaded fittings, screws, nuts, washers and
gaskets. Wall thicknesses, dimensions and other
requirements of pipes and pipe fittings are
presented in dimension standards specified in
pipe-class standards.The selection of the pipe class is dependent on the
fluid, corrosion conditions, pressure and
temperature of the pipeline.The pipe classes are used to facilitate the design,
purchasing, installation of a piping and
maintenance. -

PSK-käsikirja 6 - Penetrations
The penetrations in industrial buildings have been a gray area for both process plant and building designers. Both parties have expected something from each other that they have not always been able to define clearly. The goal in creating the standard series has been to clarify the fundamental solutions for penetrations to both parties using type drawings. By publishing this handbook, PSK Standardization provides simplified information on various types of penetrations, which supports application-specific design. However, the standards in the handbook do not take a stance on application-specific design, as there are limitless options. Each standard represents a type solution but allows the user to make more precise size and material specifications. The standards are intended to be used as construction task drawings and for penetration procurements in both domestic and international projects. They have been prepared by experts from the client, supplier, design, contracting, and technical education sectors, representing the best practices currently available. Individual standards are not published in printed versions elsewhere than in this handbook. However, PSK Standardization members receive them in PDF format via the Internet. Additionally, the images of the standards are available for further design in PDF, DWG, and DXF formats.

PSK-käsikirja 7 - Pipe classes. Part 1. Stainless steels
The 6th edition of the handbook compiles the latest versions of all PSK pipe class standards. Part 1 of the handbook includes stainless steels, and part 2 covers non-alloyed and alloyed steels under the name carbon steels. The handbook contains pipe class standards for steel piping prepared by PSK Standardisointi. A pipe class refers to a selection of pipes and pipe fittings suitable for the same pipeline, where dimensions and materials are specified. The strength of all pipes and pipe fittings has been calculated in accordance with the pressure equipment directive. The manual provides comprehensive information on piping needed for pipeline design, manufacturing, installation, and procurement. It presents the identifiers of standardized pipe classes and the materials used in these pipe classes. The pipe classes have been prepared for the steel materials most commonly used in industrial pipelines. This handbook, together with PSK Handbook 8 "Pipe Support" and PSK Handbook 9 "Industrial Insulation" as well as other PSK standards dealing with pipelines, forms the foundation of piping design. All handbooks are bilingual (Finnish and English) and are intended for use in both domestic and export projects. The standards have been prepared by experts from the client, supplier, design, contracting, manufacturing, technical trade, and inspection sectors, representing the best practices currently available. Inspection bodies have provided statements on compliance with the pressure equipment directive. The handbook and separate editions of the standards are available from PSK Standardisointi. Members of PSK Standardisointi can also access the standards in PDF format from PSK website. The dimension tables of the standards are available electronically to members.
