  • Piping arrangement drawings sections and elevations
    Pipe Drafting and Design (Third Edition), 2012
    Co-Authors: Roy A. Parisher, Robert A. Rhea
    Abstract:

    The Piping-arrangement drawing evolves from the foundation location and equipment location drawings. It shows all mechanical equipment and vessels in the unit and the pipes connecting them—including manholes, ladders, platforms, and davits. It identifies all structural supports such as pipe racks, equipment structures, columns, braces, and any fireproofing they may have. Once locations for foundations and equipment are established, Piping configurations are added to the drawing with the aid of symbols that represent fittings, flanges, and valves. The arrangement drawing is the most significant drawing developed by a Piping Designer. This plan-view drawing is a major source of information used in the fabrication and erection of the Piping facility. Information on the arrangement drawing aids in the development of the Piping model and the isometric drawings. Good dimensional arrangement and placement enhance a drawing's effectiveness. Clear, concise, well-placed dimensions not only reflect a well-thought-out drawing but also simplify communication, which minimizes checking and reduces drawing revisions.

  • Chapter 7 - Flow Diagrams and Instrumentation
    Pipe Drafting and Design, 2002
    Co-Authors: Roy A. Parisher, Robert A. Rhea
    Abstract:

    Publisher Summary This chapter provides an overview of flow diagrams and instrumentation. Flow diagrams present in a schematic drawing the flow of fluids and gases through a unit or an entire plant. With symbols representing various pieces of equipment, a flow diagram provides the Piping Designer with an overall view of the operation of a facility. The flow diagram found in this chapter is representative of the types used by many companies in the Piping industry. The process flow diagram is the first flow diagram developed by the flow diagram department. It includes major equipment, main Piping, direction of flow, operating pressure and temperature, and major instrumentation. A flow diagram is used by the Piping group to develop and lay out the plot plan. When developing the plot plan, the arrangement of the equipment in the facility reflects, in part, the logical sequence of the flow depicted on the flow diagram. However, many other factors such as code requirements, client standards and preferences, worker safety, and cost also influence the positioning of equipment. Today, almost all flow diagrams are laid out with computer-aided design (CAD), using third-party Piping packages such as Pro-Flow or individually developed company packages.

  • Pipe system design and installation
    Fiberglass Reinforced Plastics, 1995
    Co-Authors: Nicholas P. Cheremisinoff, Paul N. Cheremisinoff
    Abstract:

    This chapter discusses some of the specific properties of fiberglass-reinforced plastics (FRP) pipe and common design problems faced by the Piping Designer or project engineer. FRP pipe has been shown to have outstanding chemical and corrosion resistance, temperature capabilities, and mechanical strength. Recognition of these properties has led to its widespread use in numerous industrial applications. FRP are good thermal insulators—that is, they conduct heat more slowly than metal that expands and contracts more rapidly. This information must be considered carefully to prevent any excess stress on FRP pipe or components when connections are made to metal Piping systems. Tanks, steel Piping, and other structures can transmit significant stresses to FRP pipe; hence, these deflections created by the non-FRP system must be compensated for by independent means. In a Piping system, non-FRP lines should be anchored immediately before the FRP connection to ensure that any thermal strain is not transmitted to the FRP system.

  • Chapter 6 – Installation
    The Safety Relief Valve Handbook, 2010
    Co-Authors: Marc Hellemans
    Abstract:

    Publisher Summary This chapter cautions the Piping Designer, process engineer and user that the performance of a properly sized and selected safety relief valve (SRV) can be severely compromised when used in conjunction with improper companion Piping or incorrect handling and installation. SRV installation guidelines and their rationale, as well as some precautions, are offered to ensure optimum performance and safety. About 75% of all the problems encountered with pressure relief valves (PRVs) are due to improper installation or handling. SRVs are extremely sensitive to the effects of improper companion Piping both on inlet and outlet sides. One of the main malfunctions on primarily spring-operated SRVs is incorrectly designed inlet Piping and the resulting excessively high pressure drops. American Petroleum Institute (API) recommends a maximum pressure drop of 3%. This should be taken into account when sizing valves; higher pressure drops not only cause reduced flow but also cause quick damage to the valve due to chatter, especially when the blowdown is set below the effective pressure drop. Therefore, always try to obtain short and simple inlet Piping. Complex inlet Piping is only effective if the Piping is at least one or two pipe sizes larger than the SRV inlet and its size is reduced just before the SRV inlet.

  • Demonstrating Leak Tight Joints During Piping Design
    Volume 2: Computer Technology and Bolted Joints, 2011
    Co-Authors: David Mair
    Abstract:

    Pipe stressing programs will often show that the selected class of flange is not capable of accommodating the applied Piping moments. In this case, unless a higher class of flange is chosen or the Piping layout changed to reduce the flange moments, the pipe stressing program will indicate that the Piping does not meet all of the requirements of the Piping code. If the moments acting on the flange cannot be reduced, must a higher class of flange be chosen or are there other flange analysis techniques that can be used to show that the moments are not excessive? This paper compares a range of flange analysis techniques to investigate the bending moments that may be accommodated; both from a flange stress and from a flange leakage point of view. The objective of the work is to illustrate the variations in computed results and to help the Piping Designer choose an appropriate method for assessing flange moments. There is a multitude of different flange configurations considering combinations of flange type, size, class, schedule, gasket and the results of any comparison will be affected by many other parameters such as pressure, temperature and bolt pretension. The comparisons have thus been limited to a range of commonly used flange configurations in sizes up to 12 inch in an attempt to draw some general conclusions about the various assessment methods.Copyright © 2011 by ASME
