Block valves are usually provided upstream (and downstream if discharging into a closed system) of pressure relief valves where necessary to permit on stream isolation and maintenance of the PR devices without interrupting process unit operations.
Where block valves are used, the installation should conform to the requirements of Section VIII of the ASME Boiler and Pressure Vessel Code when protecting an unfired pressure vessel. These valves are typically installed so that they are car sealed open (CSO). Mechanical interlocks or key systems are usually required for spared PR valve installations to help ensure continuous safety protection of the system.

The designer now starts thinking about the proper orientation of nozzles and provisions for access to the points of operation and maintenance.
Considerations of the pipeline leaving the tower area and the adjacent piping shall be visualised.
The first step is to orient the manholes preferably all in same directions. Normally, manholes shall be oriented towards dropout area within a 30° segment of column as this facilitates the lowering of tower internals to the main access way. The manhole segment of platform should not be occupied by any piperack.

The basic layout and general engineering specifications describe:
- The minimum access, walkways, platforms width and headroom requirements.
- Handling facilities for tower internals, manhole covers, line blinds, relief valves.
- Maximum rise of ladders.
- Pipe-system requirements, such as open or closed relieving systems.
- Minimum line-size and required hose-stations.
- Access to valves and instruments.

Flange Specification and Identification
A flange is specified by the following information:
a) Type and Facing: i.e. whether the flange is for example “Weld Neck, RTJ” or “Socket Weld, RF”.
b) Nominal Pipe Size: required for all flanges, usually in inches.
c) Flange Pressure Class: required for all flanges, e.g. Class 150, 300, 900, 1500, 2500 etc.
d) Standard: i.e. ANSI B16.5, BS 1560, API 6A, API 605 or ASME B16.47.

To provide the layout designer guidelines for developing pump piping designs that fully consider safety, operation, maintenance and economics.
All or part of this guide may be superseded by client mandatory standards or by the codes and regulations imposed by governmental jurisdictions covering the location where the piping is installed.
Proper consideration for personnel safety around pumps requires piping and valve arrangements that do not obstruct access for operation, maintenance or egress. Care must be exercised not to create tripping hazards with auxiliary piping.
Pumps normally require minimal attention during operation. Valves however, must be located for easy access; this is particularly true for paired or spared pumps. Where manual valves cannot be operated from grade, chain operators shall be used. If chain operators are not allowed per client specifications, platform access to valves shall be considered.

Tubular products are termed ‘tube’ or ‘pipe’. Tube is customarily specified by its outside diameter and wall thickness, expressed either BWG (Birmingham wire guage) or in inches or in thousands. Pipe is customarily identified by ‘nominal pipe size’ with wall thickness defined by ‘schedule number’.
