    Internal Cladding of Pipeline - Different Thermal Expansion Coefficient

    Considering different thermal expansion between carbon steel and say, Inconel, how do they deal with anticipated deformation when internal surface of CS pipeline is cladding with Inconel?

    Maximum Torque on a Jackscrew

    I'm going to calculate (or analyze via FEM) maximum stress in a jackscrew which is used to make space for removing a valve sandwiched between two flages. I know tightening torque on that machine bolt is at first low but it will increase as far as isolating space is increased. So, how can I...

    Changing from GRE to CS for Large Pipes

    thread378-267056 I was reading this thread and with regard to OP question: I think, at that time maybe for pipes larger than 24" the available vendor of fiberglass pipe did not have an oven large enough to cure larger-than-24"-pipes. Therefore, the choice between not-cured GRVE and CS with...

    Vapor Recovery Line - On/Off Valve - Seat Selection

    There are several vapor recovery lines, which are used at gasoline loading bays. During the day, lots of tankers come and go and there is an on/off valve in vapor recovery lines that shall be normally closed unless a tanker is stopped for loading and at this time, its line shall be opened by...

    Selection of job limit/range from a complex large piping

    Hi there, In a complex petrochemical plant with a lot of piping, it's obvious that modeling all of the piping in a CAESAR II job is not a wise approach. But, is there any guideline/s for selection of lines that fall into a single job? Considering a pump station within a complex refinery, which...

    Piping Hydrodynamic Test

    Why piping codes (such as ASME B31.3) deal only with "Hydrostatic Test"? Isn't it possible to have some requirements for dynamic aspect of piping test before its operation (e.g. piping connected to the pumps)?

    Pipe Stress Engineering by Liang-Chuan Peng (Author), Tsen-Loong Peng (Author)

    Hi Piping Professionals, I'm wondering whether this "invaluable" book needs new edition considering changes that has applied to ASME B31.3 during these times (first edition, 2009). (Actually, I haven't opportunity to read this book completely, yet and I considered that book "invaluable" by...

    Paint/Coat Flowchart in Oil&Gas Field

    Hi everybody, Does anybody have any reference to paint/coat decision making flowchart? What is the main parameters in selection of protection system? I think the starting question should be whether it is onshore or offshore. What is the other hierarchically questions? Thanks in advance. Nothing...
