  • Piping systems: Determine the limiting component
    Hydrocarbon Processing, 1995
    Co-Authors: S. Kannappan
    Abstract:

    A Piping Specification is written for each service such as steam, oxygen and hydrogen. Reliable use of a component is limited by the service conditions such as pressure and temperature. The limitations are described in applicable codes and standards listed in the references. Additional data such as corrosion allowance, thread allowance, mill tolerance and yield stress are also used to determine the limiting component. Components covered in a Piping Specification are pipe, flanges, valves, fittings, unions and other special items. Examples are presented to show when a pipe, flange or valve becomes the critical or limiting component.

  • Piping Specification Optimization of Reheat Steam System for 1000MW Ultra-Supercritical Thermal Power Plant
    Power System Engineering, 2011
    Co-Authors: Zhou Guang-ji
    Abstract:

    From the aspects of initial investment and profit economy calculate and optimize the reheat steam system Piping dimensions for one 2×1000MW ultra-supercritical air-cooling thermal power plant.It selects a series of different diameter and wall thickness pipe Specifications according to design parameter,then use AFT fluid analysis software to do flow velocity and pressure loss simulation.Through quantification influence of pressure loss for steam turbine power and heat consumption,carry on comparative economic analysis,determine optimal size of cold reheat steam and hot reheat steam pipe.

  • ASME B31.3 End of Life Considerations: Corrosion, Mechanical Strength, and Small Bore Geometry
    ASME 2010 Pressure Vessels and Piping Conference: Volume 1, 2010
    Co-Authors: Dennis K. Williams
    Abstract:

    This paper discusses the prescribed requirements contained within the ASME B31.3 Process Piping Code that specifically address the considerations of the design corrosion allowance when coincidently taken into account with the mechanical strength requirements of the same. In particular, the most significant effects of the least favorable corrosion allowances in combination with the mechanical strength requirements of ASME B31.3 are prevalent in thin walled, small bore Piping of minimal geometric properties associated with the calculation of component stresses in the longitudinal direction. Careful examination of ASME B31.3 paragraph 302.4 reveals that the minimum required thickness of a Piping component include allowances for corrosion and when taken in conjunction with paragraph 302.4.1, which requires that when necessary, the wall thickness shall be increased to prevent overstress, damage, or collapse, due to superimposed loads from handling or other causes. The effects of the aforementioned Code requirements are addressed and examples are presented for small bore Piping (nps 2″ and below) that lead to a proposed small bore Piping criteria for consideration by Piping Specification engineers. Finally, the results of the evaluation of various combinations of corrosion allowance and mechanical strength requirements in terms of metal cross sectional area and section modulus are presented in tabular form that support the proposed small bore Piping criteria.Copyright © 2010 by ASME

  • Application of Electrochemical Protection Technology in Water Injection Pipeline Anticorrosion of Underground and Ground
    Materials review, 2020
    Co-Authors: Zhang Jiangjian
    Abstract:

    According to the corrosion in Tahe oilfield downhole and surface pipeline perforation serious situation,combined with the analysis of water injection wells corrosion characteristics and factors,the injection well bet the waterline corrosion is serious,according to the technical characteristics of sacrifice anode cathodic protection with sacrificial anode in TK422,injection well tubing wall installation.The test results show that,the water injection pipe wall were not obvious corrosion by P110Smaterial,the inner wall of the sacrificial anode protection compared to the point corrosion rate of unprotected droped 91%,the technology of downhole corrosion inhibition effect was obvious.And the development of anode and cathode protection technology at the expense of ground metal pipeline corrosion was studied,the metal carbon steel pipe bypass sacrificial anode protection device were designed,combined with the Piping Specification,the corrosion rate and the sacrificial anode performance parameters,that the different Specifications of pipe protecting sacrificial anode dosage range was got,economic evaluation was carried out and corrosion control suggestions are put forward.
