What are the two methods of inspection?
Some common methods are visual, industrial computed tomography scanning, microscopy, dye penetrant inspection, magnetic-particle inspection, X-ray or radiographic testing, ultrasonic testing, eddy-current testing, acoustic emission testing, and thermographic inspection.
What are the inspection techniques?
methods are visual, microscopy, liquid or dye penetrant inspection, mag- netic particle inspection, eddy current testing, x-ray or radiographic test- ing, and ultrasonic testing.
What is OCTG?
The term Oil Country Tubular Goods describes tubes that are used in oil and gas production: As a rule these include drill pipe, casing and tubing. Oil Country Tubular Goods are used both onshore and offshore. In the industry, they are also referred to by the acronym OCTG (for “Oil Country Tubular Goods”).
What are the three different types of inspection methods?
There are three primary types of quality inspections: pre-production, in-line, and final. There are a variety of details that must be inspected and approved during each phase in order to detect and correct quality problems.
What are the four inspection categories?
The four different types of inspections conducted by FDA are pre-approval inspection, routine inspection, compliance follow-up inspection, and “for cause” inspection. Each is intended to help protect the public from unsafe products, but the focus and expectations of each type of inspection are different.
What are different types of casing?
The five types of casing string are conductor casing, surface casing, intermediate casing, casing liner, and production casing.
What are the different types of OCTG inspections?
There are the OCTG Visual Thread Inspection (VTI), Visual Body Inspection (VBI, FLVI), Drift Testing, Length Measurement. Another is NDT inspections, that including Magnetic Particle Testing, Ultrasonic Testing and Liquid Penetrant Testing.
How is OCTG used in oil and gas production?
Oil Country Tubular Goods (OCTG) are used in oil and gas production. As a rule, these include drill pipe, casing and tubing that are used both onshore and offshore. Producers of heavy wall OCTG tube must meet the demands of individual client specifications, as well as API 5L & 5CT, ISO, EN and other standards.
How is magnetic flux leakage used in OCTG?
For typical OCTG and other heavy wall tube tests, Flux Leakage technology detects longitudinal and transverse defects as small as 5% on OD and ID, as well as defects within the wall, depending upon material type and condition. MFL inspection uses a DC magnetizing field to create enough flux density to bring the material to near-saturation.
How is ultrasonic testing used in Oss inspection?
Ultrasonic Testing is a family of None Destructive Testing base on the propagation of ultrasonic wave in the material tested. This would be carried out on remaining wall thickness comply with API Standard. This method can be applied on long storage pipes or suspected material, to check the remaining thickness.
