Crane Inspection – The Next Level

The OSHA Crane Rule, effective in 2010, clearly defines the requirements for crane inspections. The rule defines the frequency and minimum requirements for compliance. Crane inspections are really nothing new. We have developed our methods and procedures through years of experience. The question is: Are We Doing Enough? In my earlier years in the trades […]

A Novel Nondestructive Technique for Detecting and Sizing Carburization Damage in Heater Tubes

Fired Heaters come in many types and configurations: catalytic reformers, crude heaters, visbreakers, vacuum heaters, coker heaters, etc; and many are prone to carburization damage (i.e. residual carbon diffusing into the tube material, causing damage or even failure). Many refineries today use delayed coking processes to upgrade their crude product. This process includes the use […]

What is the Future of ASME B31.3, Appendix P?

Appendix P was written to introduce piping flexibility analysis rules that are more suitable for computer piping flexibility analysis, in contrast to the rules in the base Code which were written when piping analysis was done by hand calculations.  Most of the elements of Appendix P have been, or are proposed to be, added to […]

API 579/ASME FFS-Based Software Delivers Efficient Evaluation of Brittle Fracture Resistance and Minimum Allowable Temperature

Process vessels such as towers, drums and heat exchangers may be exposed to low temperatures as a part of normal operation or as the result of an upset condition. Carbon and low alloy steels typically used in process vessels undergo a transition from ductile to brittle behavior as temperature is reduced and are at increased […]

Crane Backward Stability  

Backward stability for cranes has always been a serious consideration and often misunderstood or overlooked. The tendency is to carefully study the capacity charts to assure frontward stability when planning a lift. It is somewhat counter intuitive to worry about backward stability as all the lifting is being done over the front. In fact, there […]

Oil System Cleaning – Making Oil Flushing a Predictable Procedure

Oil system cleaning or Oil Flush has humbled many Machinery Guys. What seems like a very simple task often turns out to be to the Achilles’ heel and often unpredicted and embarrassing critical path of the machinery overhaul. The purpose of this article is to outline improvements that we have implemented to the old-fashion “Flush […]

Performing an FEA in Section VIII, Division 1 to Qualify an Article U-2(g) Component

  While there are currently no explicit rules on how to perform a finite element analysis (FEA) if you are doing so in support of an ASME Section VIII, Division 1 vessel, there is good practice. Regarding rules, all you have is from Article U-2(g), which says: This Division of Section VIII does not contain […]

Use of Fracture Mechanics for Fatigue Design

While fracture mechanics is used in fitness-for-service, FFS, for evaluation of crack like flaws that are detected and for evaluation of the potential for brittle fracture, it is also used in new design to evaluate fatigue life. The rules for high pressure vessels in Section VIII, Div 3 and ASME B31.3 Chapter X permit and […]

Changing Your Crude Slate?

Changing Your Crude Slate? You Need to Consider More Than Just Naphthenic Acid Corrosion and High Temperature Sulfidation. Refiners are constantly evaluating their crude slates in an effort to maximize profits. It involves a continuous effort in trying to get the most product value from the lowest cost crudes. Generating a $1.00 per barrel margin […]
