METALLURGICAL CONSULTING

New York
Provide pre-assessment and design consultation for DOT / PHMSA waiver request to operate a section of the proposed pipeline at 80% SMYS in a Class I location. Project involved review of pipe design, material specification, welding procedures, application and interaction with regulatory agencies.
Texas
Engineering Critical Analysis (ECA) of 42” girth welds made with automatic welding per API 1104 Appendix A, 20th edition for weld defect acceptance criteria. Analysis combined axial stress analysis of pipeline during construction, testing, and operation; welding procedure qualification including CTOD testing; and weld defect sizing with AUT.
South Dakota
Provided design review of proposed interstate liquids line for public utility commission. Work involved review of design considerations used, evaluation of 80% SMYS waiver application to PHMSA and preparation of direct testimony for certificate hearing.
Louisiana, Texas
Review and provide revisions to pipe welding specification, welder qualification including material and construction related specifications for double joint and automatic welding.
Texas
Root cause failure analysis of weld cracks during construction of 42”, X-70 pipeline. Metallurgical samples provided allowed analysis of weld sequence and fracture characteristics to determine cause.
India
Qualify India pipe mills and SAW pipe mills as pipe suppliers. Provide specification and construction related specifications for double joint and automatic welding during construction.
Louisiana
Review and metallurgical analysis of a weld failure during a horizontal directional drill operation. Work involved field inspection of the failure, mechanical stress evaluation of drill operation, metallurgical evaluation of failed weld specimen and review of welder qualification and welding procedures.
Louisiana
Performed a review and modification of pipeline specifications with regards to welding procedures, welder qualification and automatic welding methods for all grades of pipe and for X70 and X80 in particular. An additional contract was executed to review one of the pipe mills to ensure the mill’s compliance with company standards and criteria.
Louisiana
Technical assistance and support for DOT waiver petition request to operate a new pipeline at an 80% stress level in a Class I location.
Connecticut
Assisted a major distribution company in the Eastern U.S. in re-establishing a welding procedure to verify the procedures adequacy for joining pipes with unequal yield strength. The work allowed the company to use welds performed in the field while maintaining stress levels below 20% SMYS, thus classifying the line as distribution piping rather than as a transmission line.
Texas
Performed failure analyses of pipe failure during commissioning hydrotest. Pipe was determined to be over pressurized causing tensile failure in the pipe and excessive deformation.
Texas
Provided metallurgical technical support at the Jindal Saw Pipe Mill in Baytown, TX. Reviewed and revised the Pipe Specification, particularly in regards to meeting requirements for the 80% stress level.
Texas
Performed stress analysis of pipe during construction, testing and operation of a 170 mile, 42” X70 line in support of Engineering Critical Analysis for weld procedure acceptance criteria.
Iowa
Investigated corrosion of separator vessel and meter run piping including chemical analysis of liquid and solid samples and corrosion morphology.
Kansas
Investigated casing design in support of cracked girth weld failure at a rail crossing including load transfer through soils and vibration analysis.
Kentucky
Hydrotest and metallurgical examination of vintage pipe girth welds for pipeline integrity evaluation.
Illinois
On site examination and metallurgical analysis of failed elbow and associated piping in storage field drip.
Gujarat, India
Pipe mill inspection to evaluate pipe manufacturing process and inspection of pipe production at a mill in Anjar, Gujarat, India
Nevada, Arizona, and California
Developed an engineer training and development program to cover design standards. These standards covered the entire company system from mains and services, to material selection and testing.
