    High Presure Pipeline

    Hello, I am looking for some guidance on determining what applicable codes and/or regulations would apply to siting a transmission line structure next to underground high pressure gas lines. NESC discusses grounding and/or grounded structure requirements. Does anyone know of any other...

    Power Pole Clearance - Ground Disturbances

    I am well aware that codes do not stipulate the construction techniques or method used, however code do specify such things as safe working distances from energized parts, clearances, etc. I don’t believe it is so unrealistic to think with all the power line in the US that some entity might...

    Power Pole Clearance - Ground Disturbances

    The utility engineers are involved and seem to be looking to us to provide insight/guidance. The code is pretty clear on horizontal and vertical clearances such as distances from the track to the base of the structures, etc. Just seem like there would be at the very least recommend practice...

    Power Pole Clearance - Ground Disturbances

    Does anyone know of a code or industrial standards that specify the clearance of any ground disturbances should be kept from the base of the adjacent power poles structures to avoid weakening the foundations? The planned project is for a new rail road track to be constructed parallel to an...

    Drill Casings

    I was recently given a drill casing specification by my client that specified H40 7 inch production casing 16 lb/ft and a H40 10.75 inch surface casing 22 lb/ft. However, I have been unable to find any reference to the above mentioned casing. The closest match I have found is 17 lb/ft on the...

    Can someone recomment book/manual?

    I do not know of a users manual for algor and the only text that I am aware that has examples of algor problems is Linear and Nonlinear Finite Element Analysis in Engineering Practice written Dr. Constantine Spyrakos. This text is more on the basics of FEA with limited software interface...

    Lack of Preheat

    Thanks, Additional thoughts, I know that the weld process deviated from the code, therefore I am liable if this joint fails (if I accept the deviation). Per the code, the course of action would be to qualify the weld duplicating the conditions actually used (a new WPS with the lower/no...

    Lack of Preheat

    Hello, Here is my dilemma. A recent inspection revealed that the required preheat was not followed per AWS code. The joint: A36 base plate (2 inches thick), A992 Column (W10 x 77). Required preheat was 150 F. Visual inspection showed no sign of cracking. The ambient conditions are not...

    Simulating a fluid

    Here is my dilemma ........ I am designing a large elevated tank (open) and would like to model the tank to verify/check my hand cal's for the reactions on my support columns due to seismic loading. Which brings me to my question, what is the best way to model the fluid. I am not concerned...

    Weld Stress

    The base allowable stress in tension, Sa, is specified in BPVC and depends on the material and the temperature. For specification SA-516 70 temperature range of -20F to 650F is 17,500 psi. The joint efficiency (E) used in calculation for seamless shells is 1. For weld joints subject to...

    Weld Group Analysis

    Welding1, Thanks for our response. I should have stated that the weld group is subject to a parallel load (shear). The weld joint is a 15" diameter bushing approximately 9" long being welded to a 24” OD flange 2” thick. I also have no problem analysis the welds independently. What...

    Weld Group Analysis

    Hello, I am writing in hopes of acquiring information on the analysis of a groove & fillet weld group. Here is my question: In analyzing a groove weld "capped" with a fillet weld how is the strength of the weld determined. More specifically, how is the effective throat measured...

    Welding Courses?

    Hello, I am inquiring about any weld courses that may be offered through various organizations, which would cover theory, procedures, and inspection. I am looking for something that is geared more towards a design-engineering role. I am considering ASME’s course, “Practical Welding...

    EP Lubricants

    What is the difference between an extreme pressure (EP) lubricant and a lubricant that has extreme pressure additives? If gear oil contains the EP additives is that enough to classify it as an EP lubricant? I define each as follows: EP (Extreme Pressure) lubricants -- lubricants that impart...

    Natural frequencies and Finite Element Analysis

    Cadbury_Girlno, I have been looking for similar literature regarding the natural frequency of fluid filled tanks. The best resourse I have found so far is Algor's web site. Algor's Mechanical Event Simulation software does account for the inertia and its influence on a structures loading...
